How to Explore Yellowstone: A Complete Visitor’s Guide

To truly explore Yellowstone is to step into a world unlike any other on Earth. As the world’s first national park, established in 1872, Yellowstone National Park protects a vast wilderness teeming with geothermal wonders, iconic wildlife, and breathtaking landscapes. Covering nearly 3,500 square miles primarily in Wyoming, but also extending into Montana and Idaho, this remarkable place offers endless opportunities for adventure, discovery, and connection with nature.

However, its sheer size and complexity can be daunting for first-time visitors. This guide aims to provide you with the essential information needed to plan and execute an unforgettable trip, ensuring you make the most of your time as you explore Yellowstone.

Why Explore Yellowstone National Park?

Yellowstone’s allure lies in its unique combination of features. Firstly, it sits atop a massive volcanic caldera, resulting in the planet’s highest concentration of geothermal features. Think geysers erupting skyward, bubbling mud pots, steaming fumaroles, and vividly colored hot springs. Secondly, it’s one of the last nearly intact temperate ecosystems on Earth, providing sanctuary for an incredible array of wildlife, including grizzly bears, wolves, bison, elk, and pronghorn.

Furthermore, the park boasts stunning scenery, from the deep chasm of the Grand Canyon of the Yellowstone with its powerful waterfalls to the serene expanse of Yellowstone Lake and the rugged beauty of its mountain ranges. Consequently, exploring Yellowstone offers a chance to witness raw nature, learn about geology and ecology, and create lasting memories.

Planning Your Yellowstone Adventure

Proper planning is crucial for a successful trip to explore Yellowstone. The park’s immense scale and popularity necessitate forethought, especially regarding timing, duration, and accommodation. Taking the time to plan will ultimately lead to a smoother and more enjoyable experience.

Best Time to Explore Yellowstone

Yellowstone is technically open year-round, but accessibility varies dramatically by season.

• Summer (June – August): This is the peak season. All park roads, facilities, and entrances are typically open. Consequently, you’ll experience the best weather, with warm days and cool nights, perfect for hiking and sightseeing. However, this is also the busiest time, meaning significant crowds at popular attractions and potential traffic delays. Accommodation books up months, sometimes over a year, in advance.
• Fall (September – October): Many consider fall the ideal time to explore Yellowstone. Crowds thin out considerably after Labor Day, yet most facilities remain open through September, with some into October. The weather is crisp and cool, autumn colors paint the landscape (especially aspens), and the elk rut (mating season) offers exciting wildlife viewing opportunities. However, be prepared for colder temperatures, potential snow, and road closures later in the season.
• Winter (Mid-December – Mid-March): Winter transforms Yellowstone into a magical, snow-covered wonderland. Most park roads close to regular vehicles, limiting access to oversnow travel (snowmobiles or snowcoaches) primarily from the North Entrance to Mammoth Hot Springs and Cooke City, or via guided tours to places like Old Faithful. It offers unique solitude, cross-country skiing, snowshoeing, and excellent wolf-watching opportunities. Facilities are minimal, and conditions are harsh.
• Spring (April – May): Spring is a time of transition and emergence. Snow begins to melt, roads gradually reopen (check schedules!), and wildlife, including baby bison and bears emerging from hibernation, becomes more active at lower elevations. However, weather is highly unpredictable, ranging from sunny days to heavy snow. Many trails remain snow-covered, and some facilities don’t open until late May or early June. Road openings are staggered, so check the park website frequently.

How Long Should You Stay?

While a quick drive-through is possible, it barely scratches the surface. To adequately explore Yellowstone’s major highlights along the Grand Loop Road, plan for a minimum of 3-4 full days. This allows you to visit the main geyser basins, the Grand Canyon of the Yellowstone, Mammoth Hot Springs, and spend some time looking for wildlife.

For a more immersive experience, including time for hiking, attending ranger programs, or exploring less-crowded areas, 5-7 days is highly recommended. This pace allows you to delve deeper, perhaps take a boat tour on Yellowstone Lake, hike a few trails, and spend more quality time in wildlife hotspots like the Lamar Valley. If you truly want to experience the backcountry or explore extensively, plan for even longer.

Getting To Yellowstone

Yellowstone is relatively remote. Therefore, your travel method depends significantly on your starting point and personal preferences.

• Flying: Several regional airports serve the Yellowstone area:
  • Bozeman Yellowstone International Airport (BZN) in Montana: Often the most popular choice, located about 90 minutes from the North or West Entrances.
  • Jackson Hole Airport (JAC) in Wyoming: Located south of the park, inside Grand Teton National Park. Convenient if combining both parks, but typically more expensive.
  • Yellowstone Airport (WYS) in West Yellowstone, Montana: Closest airport (minutes from the West Entrance), but operates only seasonally (usually June-September) with limited flights.
  • Idaho Falls Regional Airport (IDA) in Idaho: About a 2-hour drive to the West Entrance.
  • Cody Yellowstone Regional Airport (COD) in Wyoming: About a 1-hour drive to the East Entrance (East Entrance is seasonally closed).
• Driving: Many visitors choose to drive, incorporating Yellowstone into a larger road trip. Major highways like I-90 (north) and I-80 (south) provide access to connecting routes leading to the park entrances. Driving undoubtedly gives you the most flexibility for exploring the park at your own pace.

Entrance Fees and Passes

You’ll need to pay an entrance fee to explore Yellowstone. As of late 2023/early 2024 (always check the official NPS website for current rates), the standard fee is $35 per private vehicle, valid for 7 days. Alternatively, consider purchasing an America the Beautiful Pass for $80. This annual pass grants access to all US National Parks and federal recreational lands for a full year, often proving a better value if you plan to visit multiple parks within twelve months.

Booking Accommodation and Camping

Securing lodging is one of the most critical planning steps, particularly for summer visits when demand skyrockets.

• Inside the Park: Yellowstone offers nine lodges and numerous campgrounds managed by Xanterra Parks & Resorts and the National Park Service (NPS), respectively. Lodges range from historic hotels like the Old Faithful Inn to rustic cabins. Campgrounds vary from large sites with amenities to more basic options. Importantly, reservations open over a year in advance and fill extremely quickly. Book ASAP via the official concessioner (Xanterra for lodges) and Recreation.gov (for most NPS campgrounds). Staying inside the park maximizes your time for exploration and minimizes driving.
• Outside the Park: Gateway towns like West Yellowstone (MT), Gardiner (MT), Cody (WY), Jackson (WY), and Cooke City (MT) offer a wide range of hotels, motels, vacation rentals, and private campgrounds. These provide more options and amenities but inherently require driving into and out of the park each day. Consequently, this can add significant travel time, especially during peak season traffic.

Navigating Yellowstone National Park

Understanding the park’s layout and how to get around is essential for an efficient trip. Indeed, Yellowstone’s vastness requires strategic planning to minimize backtracking and maximize your time exploring its wonders.

The Grand Loop Road

The main artery for exploring Yellowstone is the Grand Loop Road. Shaped like a figure-eight, this 142-mile (229 km) road connects most of the park’s major attractions. It’s typically divided into the Upper Loop and the Lower Loop for easier planning.

• Lower Loop: This popular section accesses Old Faithful, the Upper, Midway, and Lower Geyser Basins, Grand Prismatic Spring, Yellowstone Lake, West Thumb Geyser Basin, Hayden Valley, and the Grand Canyon of the Yellowstone. It’s arguably the most visited loop due to the high concentration of geothermal features and the spectacular canyon.
• Upper Loop: This loop takes you through Mammoth Hot Springs, Norris Geyser Basin, the Tower Fall area, and the famed Lamar Valley. It’s particularly renowned for wildlife viewing opportunities (especially in Lamar Valley) and the unique travertine terraces found at Mammoth.

Driving the entire Grand Loop without significant stops takes approximately 4-7 hours. Realistically, however, you’ll need much longer to account for sightseeing stops, inevitable wildlife jams (bison frequently cause delays!), and potential road construction delays during summer.

Transportation within the Park

The vast majority of visitors explore Yellowstone using their own private vehicle or a rental car. Undoubtedly, this offers the greatest flexibility to stop whenever and wherever intriguing sights appear. Always ensure your vehicle is in good condition before entering, and consistently start the day with a full tank of gas, as gas stations within the park are limited and distances between them can be substantial.

Alternatively, various commercial bus tours operate within the park, departing from gateway towns or locations inside the park itself. These can be a good option if you prefer not to drive, offering guided commentary and structured itineraries. However, be aware that they follow set schedules and routes, limiting spontaneity. During winter, access shifts primarily to commercial snowcoaches and snowmobiles (either guided or through permitted non-guided trips).

Park Entrances

Yellowstone has five main entrances, each offering access to different areas and operating on varying seasonal schedules:

1. North Entrance (Gardiner, MT): The only entrance open to wheeled vehicles year-round. Provides direct access to Mammoth Hot Springs and the scenic road leading through Lamar Valley to Cooke City.
2. West Entrance (West Yellowstone, MT): Typically the busiest entrance. Opens seasonally (usually mid-April to early November). Offers convenient access to the major geyser basins on the west side.
3. South Entrance (Near Grand Teton NP, WY): Opens seasonally (usually mid-May to early November). Ideal if you plan to combine your Yellowstone trip with a visit to Grand Teton National Park immediately to the south.
4. East Entrance (Near Cody, WY): Opens seasonally (usually early May to early November). Provides primary access to the eastern side of Yellowstone Lake.
5. Northeast Entrance (Near Cooke City, MT): Opens seasonally for wheeled traffic connecting to the interior (usually late May to mid-October), however, the road from Mammoth through Lamar Valley to Cooke City via the North Entrance remains open year-round. Accesses Lamar Valley directly.

Your choice of entrance often depends logically on your overall travel route and the location of your booked accommodation.

Visitor Centers

Visitor Centers are invaluable resources as you explore Yellowstone. Make it a point to stop at one near your entrance or first major attraction. Rangers provide crucial, up-to-date information on road closures, current trail conditions, recent wildlife sightings, weather forecasts, and schedules for ranger-led programs. Moreover, these centers host informative exhibits detailing the park’s fascinating geology, diverse ecology, and rich human history. Major centers include Albright (Mammoth), Old Faithful, Canyon Village, Grant Village, and Fishing Bridge.

Cell Service and Connectivity

Be prepared for limited to non-existent cell service and Wi-Fi throughout most of Yellowstone National Park. Service is generally best near major developed areas like Mammoth, Old Faithful, Canyon Village, Grant Village, and Lake Village, but even there, it can be spotty and unreliable.

Do not depend solely on your phone for navigation or emergency communication in most park areas. Download offline maps (like Google Maps offline areas or dedicated apps like Gaia GPS) before entering the park. For backcountry travel or added safety, consider carrying a satellite communication device (like a Garmin inReach or Spot). Ultimately, embrace the opportunity to disconnect and immerse yourself in the natural world.

Key Areas to Explore Yellowstone

Yellowstone’s myriad wonders are spread across its vast expanse. Focusing on key areas helps structure your visit effectively. These regions offer the highest concentration of iconic features and activities essential to the Yellowstone experience.

Explore Yellowstone’s Famous Geyser Basins

Yellowstone hosts over 10,000 hydrothermal features, including more than 500 geysers – roughly half the world’s total. Consequently, exploring these dynamic landscapes is a primary draw for many visitors. Remember to always stay on designated boardwalks and trails when you explore Yellowstone; the ground is fragile and dangerously hot just beneath the surface, requiring utmost caution.

• Upper Geyser Basin & Old Faithful: This area is arguably the most famous place to explore Yellowstone’s geothermal activity. It is home to the iconic Old Faithful geyser, which erupts predictably throughout the day (check the visitor center or NPS app for estimated times, though intervals do vary). Furthermore, this basin contains the largest concentration of geysers in the world. Allow several hours to walk the extensive boardwalk system, viewing numerous other geysers like the impressive Grand Geyser and colorful hot springs such as the stunning Morning Glory Pool.
• Midway Geyser Basin: Visitors exploring Yellowstone should not miss Midway, famous for the breathtaking Grand Prismatic Spring. This is Yellowstone’s largest hot spring and the third largest globally. Its vibrant rainbow colors are best appreciated from the nearby Fairy Falls Overlook Trail, a relatively easy hike offering a panoramic perspective. Additionally, you can witness the power of the Excelsior Geyser crater as it pours steaming water into the Firehole River. Be prepared for crowds, especially during peak afternoon hours.
• Lower Geyser Basin: This basin offers variety as you explore Yellowstone’s thermal features. The Fountain Paint Pot Trail showcases all four types: geysers (like Fountain Geyser and Clepsydra Geyser), hot springs, mud pots (thick, bubbling mud providing a unique sensory experience), and fumaroles (steam vents hissing from the earth). Nearby, the seasonal, one-way Firehole Lake Drive provides close-up views of Great Fountain Geyser and the intriguing Firehole Lake.

Explore Unique Thermal Areas in Yellowstone

Beyond the major basins clustered near Old Faithful, other areas offer distinct and fascinating thermal sights as you explore Yellowstone. These locations showcase the geological diversity within the park’s volcanic caldera.

• Norris Geyser Basin: Known as Yellowstone’s oldest, hottest, and most dynamic thermal area, Norris presents a starkly different environment. It comprises two distinct sections: Porcelain Basin, offering a wide, almost treeless landscape filled with steaming vents and milky-blue, acidic pools, and Back Basin, a more wooded area featuring impressive features like Steamboat Geyser. Steamboat is the world’s tallest active geyser, although its major eruptions are infrequent and unpredictable. Prepare for strong sulfur smells throughout this volatile basin.
• Mammoth Hot Springs Terraces: Located near the North Entrance, these features are dramatically different from the geyser basins. Here, hot water rich in calcium carbonate cascades over limestone, creating intricate travertine terraces that constantly change and grow. These formations resemble beautifully sculpted, inside-out caves. You can explore both the Upper and Lower Terraces via well-maintained boardwalks. Additionally, keep an eye out for elk, as they frequently graze and rest among the terraces and in the historic Mammoth Hot Springs village area.
• West Thumb Geyser Basin: Situated directly on the scenic shores of Yellowstone Lake, this basin offers a unique juxtaposition of hydrothermal activity and the vast lake. Features here, including some underwater geysers like the famous Fishing Cone, extend directly into the cold lake waters. The stunning backdrop of the lake and the distant Absaroka Mountains makes West Thumb a particularly picturesque spot to explore Yellowstone’s geothermal wonders.

Explore Yellowstone’s Wildlife Havens

Yellowstone offers arguably the best wildlife viewing opportunities in the contiguous United States. Patience and timing are undeniably key elements for success. Dawn and dusk are typically the most productive times for spotting animals. Crucially, always maintain a safe distance: at least 100 yards (91 meters) from bears and wolves, and 25 yards (23 meters) from bison, elk, and other animals. Never, under any circumstances, feed wildlife. Binoculars or a spotting scope will significantly enhance your viewing experience.

• Lamar Valley: Often called “America’s Serengeti” for its wide-open vistas and abundant wildlife, this northeastern corner is prime habitat for bison herds, pronghorn, coyotes, and is globally recognized as one of the best places to potentially spot wolves. Patience is essential here; pull over safely in designated pullouts, turn off your engine, and carefully scan the landscape, paying attention to ridges and openings in the trees.
• Hayden Valley: Another expansive valley located centrally between Yellowstone Lake and Canyon Village, Hayden Valley is also excellent for viewing large bison herds, various waterfowl along the Yellowstone River, herds of elk, and occasionally grizzly bears or wolves, especially during the cooler hours of early morning or late evening. Numerous paved pullouts along the road offer safe viewing spots away from traffic.
• Other Areas: Remember that wildlife can appear almost anywhere as you explore Yellowstone. Keep a watchful eye along the Madison River (often good for trumpeter swans, elk, bison), near Mammoth Hot Springs (where elk are frequently seen grazing on lawns), and around Yellowstone Lake (look for waterfowl, potentially river otters or even moose in marshy inlets). Always be aware that bears can be encountered on trails throughout the park, not just in the major valleys.

Explore Yellowstone’s Majestic Landscapes

Beyond the famous geysers and abundant wildlife, Yellowstone’s diverse scenery is genuinely awe-inspiring at every turn.

• Grand Canyon of the Yellowstone: Not to be confused with the Grand Canyon in Arizona, this breathtaking, V-shaped canyon carved by the powerful Yellowstone River is a must-see. Highlights include the thundering Upper and Lower Falls of the Yellowstone River. Numerous viewpoints along the North Rim (like Lookout Point, Red Rock Point, Inspiration Point, Grandview Point) and the South Rim (including the iconic Artist Point, Grandview Point, Moran Point) offer stunning perspectives of the falls and the colorful canyon walls. Artist Point on the South Rim provides that classic, postcard-perfect view often seen in photographs. Several trails, like Uncle Tom’s Trail (check status) and Brink of the Lower Falls Trail, descend partway into the canyon for different, more immersive vantage points.
• Yellowstone Lake: As the largest high-elevation lake (above 7,000 feet) in North America, Yellowstone Lake dominates the southeastern portion of the park. Its vast, shimmering blue expanse offers opportunities for boating (rentals and guided tours are available at Bridge Bay Marina), fishing (a Yellowstone-specific permit is required), scenic drives along its shoreline (particularly the picturesque route towards the East Entrance), and exploring the unique West Thumb Geyser Basin located right on its edge.
• Mount Washburn: One of the park’s highest peaks accessible by trail (or a challenging dirt road, always check current conditions and vehicle restrictions), Mount Washburn offers unparalleled views. Hiking to the summit (a moderate to strenuous effort depending on the trail chosen) rewards visitors with spectacular panoramic 360-degree views encompassing much of the park, including the Yellowstone caldera rim, the vastness of Yellowstone Lake, and distant mountain ranges like the Tetons on clear days. A historic fire lookout tower sits at the summit, often staffed in summer.

Enhancing Your Yellowstone Exploration

Maximize your visit by participating in various activities that allow you to experience the park in different, often more intimate ways beyond simply driving the loop road.

Hiking in Yellowstone

Yellowstone boasts over 900 miles of hiking trails, ranging from easy, accessible boardwalk loops around geyser basins to challenging multi-day backcountry expeditions. Day hiking is an excellent way to escape the roadside crowds, discover hidden gems, and truly immerse yourself in the natural environment.

• Easy Walks: Consider the numerous boardwalk trails through the major geyser basins (Upper, Midway, Norris, West Thumb, Mammoth), the short Wraith Falls Trail near Mammoth, the pleasant Trout Lake Loop in Lamar Valley (good for potential otter sightings), or the Pelican Creek Nature Trail near Fishing Bridge.
• Moderate Hikes: Popular options include the Fairy Falls Trail (leading to the Grand Prismatic Overlook and then onto the impressive waterfall), the Storm Point Loop Trail offering great views of Yellowstone Lake, the relatively easy Natural Bridge Trail near Bridge Bay, or the Beaver Ponds Loop starting near Mammoth (good chance for wildlife).
• Strenuous Hikes: For experienced hikers seeking a challenge, consider the Mount Washburn Trail (either from Dunraven Pass or Chittenden Road), the steep Avalanche Peak Trail (offering incredible views but check conditions as it holds snow late), or numerous permitted backcountry trails leading deep into the wilderness.

Always carry essential gear: sufficient water, high-energy snacks, layers of clothing (weather changes fast!), sun protection, a reliable map, and bear spray (carried accessibly and know how to use it!). Importantly, check trail conditions at a visitor center before heading out, as closures due to bear activity, high water, or lingering snow are common, especially in spring and early summer. Whenever possible, hike in groups and make noise periodically on the trail to alert wildlife of your presence.

Boating and Fishing

Yellowstone Lake and the smaller Lewis Lake offer wonderful opportunities for boating adventures. Guided scenic cruises on Yellowstone Lake and various rental boats (including motorboats, rowboats, and kayaks) are available at Bridge Bay Marina.

Fishing is permitted in many park rivers and lakes, but requires a specific Yellowstone National Park fishing permit (mandatory for anglers 16 and older; state fishing licenses are not valid within the park). Be absolutely sure to familiarize yourself with and follow all specific regulations regarding permitted bait, catch-and-release areas, size and species limits, and crucial protocols for preventing the spread of aquatic invasive species.

Ranger Programs

Participating in ranger-led programs is a fantastic and often free way to deepen your understanding and appreciation as you explore Yellowstone. Programs typically include guided walks focusing on geology or ecology, evening campfire programs filled with stories and history, informative talks held at visitor centers, and engaging junior ranger activities designed specifically for younger visitors.

Check the park newspaper (provided upon entrance), look at bulletin boards at visitor centers, or inquire with rangers for current schedules, topics, and locations during your visit. These programs offer invaluable insights directly from knowledgeable park staff.

Photography Opportunities

Undeniably, Yellowstone is a photographer’s paradise, offering endless subjects. Capture stunning landscapes bathed in morning light, the otherworldly colors and textures of unique geothermal features, and unforgettable images of iconic wildlife. Generally, the early morning and late afternoon light – the “golden hours” – provide the most dramatic illumination for landscape photography.

For wildlife, a telephoto lens is practically essential for capturing frame-filling shots safely from the required distances. Furthermore, a sturdy tripod can be very helpful for achieving sharp images in low-light situations (like dawn/dusk) and for precise composition in landscape shots. Always remember to be patient – waiting for the right light or animal behavior pays off. Most importantly, prioritize your safety and the well-being of wildlife and park resources over getting the perfect shot; adhere strictly to all park regulations.

Essential Packing List for Exploring Yellowstone

Safety First: Critical Considerations

Exploring Yellowstone is generally a safe undertaking, but constant awareness and preparedness are vital for mitigating risks. Natural hazards are inherent to this wild environment, and respecting park regulations is crucial for protecting both yourself and the park’s invaluable natural and cultural resources.

Wildlife Safety

• Bears (Grizzly and Black): Critically, maintain at least 100 yards (91 m) distance. Always carry bear spray and know precisely how to deploy it effectively (keep it readily accessible on your belt or pack strap, not buried inside your backpack). When hiking, travel in groups if possible, make noise frequently (talking loudly, clapping hands) to avoid surprising bears. Securely store all food, garbage, and scented items in vehicles or designated bear-proof containers; never leave food unattended, even for a moment. Promptly report all bear sightings to park rangers.
• Bison and Elk: Maintain at least 25 yards (23 m) distance. Bison may appear docile but are powerful, unpredictable, and can charge without warning if they feel threatened or annoyed. Never approach them for photos or any other reason. Elk can also be dangerous, especially protective cows with calves and bulls during the fall mating season (rut). Stay clear and give them ample space.
• Other Wildlife: Do not approach or attempt to feed any wildlife, including smaller animals like ground squirrels, marmots, or birds. Feeding wildlife is harmful to them and illegal.

Geothermal Area Safety

• Stay on Boardwalks and Trails: This rule is paramount. The ground surrounding thermal features is often thin, fragile, and unstable, concealing pools of scalding water just beneath the surface. Falling through the crust can result in severe burns or even death. Supervise children very closely at all times in these areas.
• Do Not Touch Features or Throw Objects In: Touching thermal features can damage their delicate formations. Throwing objects (coins, trash, rocks) into pools or vents damages the features, pollutes the water, and is strictly prohibited.

Driving Safety

• Obey Posted Speed Limits: Park roads are often narrow, have sharp curves, and lack wide shoulders. Wildlife frequently crosses roads unexpectedly, especially during dawn, dusk, and nighttime hours. Drive defensively.
• Use Designated Pullouts: Always use paved pullouts for stopping to view wildlife or scenery. Never stop in the middle of the traffic lane, as this creates dangerous situations and significant backups. Exercise patience during inevitable traffic jams (often caused by wildlife sightings).
• Be Aware of Road Conditions: Check the official NPS website or visitor centers for current information on temporary road closures due to weather events (snow, ice, flooding), accidents, or seasonal construction projects. Drive cautiously, particularly at night or during periods of rain, snow, or fog.

Weather and Altitude

• Be Prepared for Anything: Yellowstone’s weather is notoriously unpredictable and can change dramatically within hours. Snowfall is possible during any month of the year, even July or August. Always dress in layers you can easily add or remove, and carry reliable rain gear (jacket and pants). Hypothermia is a genuine risk even on cool summer days if you get wet and chilled.
• Altitude Sickness: Most areas accessible by road in Yellowstone sit above 6,000 feet (1,829 m), with some points exceeding 8,000 feet (2,438 m). Allow your body time to acclimatize, especially if arriving from sea level. Stay well-hydrated by drinking plenty of water, avoid overly strenuous activity on your first day, listen to your body, and be aware of potential symptoms like headache, nausea, unusual fatigue, and shortness of breath. Descend to a lower elevation if symptoms are severe.

Responsible Tourism: Leave No Trace

To ensure the protection and preservation of Yellowstone’s unique environment for future generations to enjoy, it’s essential that all visitors practice Leave No Trace principles diligently during their stay.

• Plan Ahead and Prepare: Know the park regulations and special concerns for the areas you’ll visit. Check weather forecasts and trail conditions. Pack appropriate gear and clothing to ensure safety and comfort.
• Travel and Camp on Durable Surfaces: Stay on marked trails, boardwalks, and established paths. When camping, use designated campsites only. Avoid trampling vegetation or creating new trails.
• Dispose of Waste Properly: Pack it in, pack it out. This includes all trash, food scraps, and even toilet paper. Use provided restrooms whenever possible. If necessary, dig catholes 6-8 inches deep at least 200 feet (about 70 big steps) from water sources, trails, and campsites for human waste.
• Leave What You Find: Resist the temptation to take natural objects like rocks, wildflowers, antlers, or wood. Leave historical or cultural artifacts untouched. Observe, photograph, but do not collect. Avoid disturbing natural features or structures.
• Minimize Campfire Impacts: Where campfires are permitted (check current fire restrictions!), use established fire rings or fire pans. Keep fires small and manageable. Burn only small pieces of dead and downed wood. Ensure fires are completely extinguished – cold to the touch – before leaving the site or going to sleep.
• Respect Wildlife: Observe wildlife from a safe and respectful distance using binoculars or telephoto lenses. Never feed animals, as it harms their health, alters natural behaviors, and can make them aggressive. Store food and scented items securely to avoid attracting wildlife.
• Be Considerate of Other Visitors: Keep noise levels down to respect the natural quiet and the experience of others. Yield to fellow hikers on trails. Manage pets responsibly where allowed (generally restricted to developed areas and must be leashed). Share the trail and viewpoints courteously.
