National Park Field Guide

Explore the landscapes, trails, wildlife, caves, and unforgettable destinations protected within national parks across the United States and around the world.

National Park Field Guide is built for people who want to go beyond simply checking a park off a list. Whether you are planning your first national park trip, searching for a hiking trail, learning about wildlife, exploring underground caves, or discovering parks in another country, you can use the guides here to understand what makes each protected landscape worth exploring.

Start with one of the main guides below, choose a park that interests you, and then dig deeper into its trails, natural features, wildlife, history, and travel possibilities.

🇺🇸 Explore U.S. National Parks

From the granite walls of Yosemite and the geysers of Yellowstone to the wetlands of the Everglades and the immense wilderness of Alaska, the United States has 63 sites with the National Park designation.

Our U.S. National Parks hub brings all 63 together in one place. Browse parks by region, discover destinations you may not have considered, and follow the individual park guides to explore hiking trails, scenic drives, wildlife, caves, geological features, and other attractions.

Some parks can be explored comfortably over a long weekend. Others are so large and varied that even a week barely scratches the surface. Whether you are drawn to mountains, deserts, forests, coastlines, islands, grasslands, or tropical environments, there is a national park landscape to explore.

🌍 Discover International National Parks

National parks extend far beyond the United States.

Across the world, protected landscapes preserve Himalayan mountains, African savannas, tropical rainforests, Patagonian wilderness, European lakes, coral reefs, volcanoes, deserts, and remote islands.

Our International National Parks guide organizes the site’s growing collection of parks across Africa, Asia, Europe, Australia and Oceania, North America outside the United States, and South America.

Explore destinations such as Sagarmatha National Park in Nepal, Amboseli National Park in Kenya, Fiordland National Park in New Zealand, and Torres del Paine National Park in Chile.

🥾 Find Your Next Hiking Trail

Some of the best national park experiences begin where the road ends.

The Trails & Hiking hub brings together individual trail guides, park hiking roundups, short walks, mountain hikes, desert routes, waterfall trails, and more challenging backcountry adventures.

You can explore shorter experiences such as the Best Short Hikes in Glacier National Park Under 5 Miles or dig into major hiking destinations with guides to places such as Rocky Mountain National Park, Mount Rainier National Park, and Grand Canyon National Park.

Difficulty varies enormously from one park to another, so always consider distance, elevation gain, altitude, heat, weather, terrain, water availability, and current conditions before choosing a trail.

🦬 Discover National Park Wildlife & Plants

The scenery may get your attention first, but national parks are also living ecosystems.

Bison, bears, elk, wolves, birds, reptiles, amphibians, insects, giant trees, desert cacti, wildflowers, tropical plants, and countless smaller organisms all contribute to the landscapes protected within national parks.

Our Wildlife & Plants hub explores the animals, forests, grasslands, wetlands, deserts, and plant communities found throughout national parks.

Learn about the wildlife of Theodore Roosevelt National Park, explore the Giant Forest in Sequoia National Park, or step into the moss-covered world of the Hoh Rainforest in Olympic National Park.

The more you understand about an ecosystem, the more interesting the park becomes.

🦇 Go Underground in Caves & Caverns

Some of the most fascinating national park landscapes cannot be seen from an overlook.

The Caves & Caverns hub explores underground landscapes throughout the National Park System, including enormous limestone cave systems, talus caves, mineral formations, cave wildlife, and the geology responsible for creating them.

Explore Carlsbad Caverns National Park, discover the immense network beneath Mammoth Cave National Park, learn about the unusual boxwork of Wind Cave, or visit Jewel Cave National Monument.

You can also discover individual underground features such as Lehman Caves in Great Basin National Park and Balconies Cave in Pinnacles National Park.

🗺️ Plan Your National Park Trip

Choosing where to go is only the beginning.

Season, weather, road access, reservations, lodging, permits, transportation, hiking difficulty, wildlife, and park size can all dramatically affect a trip.

The National Park Travel & Planning hub brings those practical pieces together. Use it to think through when to visit, where to stay, how to get around, what to reserve, what to pack, and how much you can realistically fit into a day.

You can also explore destination-specific guides such as our 7-Day Yellowstone National Park Itinerary or learn about famous scenic routes such as Going-to-the-Sun Road in Glacier National Park and Skyline Drive in Shenandoah National Park.

Good planning should make a national park trip easier—not turn it into an hour-by-hour checklist.

🌄 Featured National Park Guides

Not sure where to begin? These guides offer a mix of major parks, hiking destinations, scenic routes, wildlife, and unusual landscapes:

🌎 More Than Famous Landmarks

National parks are often associated with a handful of famous views: Old Faithful erupting in Yellowstone, Half Dome rising above Yosemite Valley, Delicate Arch glowing in Utah, or Denali towering over the Alaska Range.

Those landmarks are worth seeing, but they represent only a fraction of what protected landscapes have to offer.

A national park may preserve migration habitat for wildlife, forests containing ancient trees, archaeological sites connected to thousands of years of human history, geological features revealing enormous spans of Earth’s past, or ecosystems containing species found almost nowhere else.

Sometimes the most memorable place in a park is not the famous viewpoint. It may be a quiet trail, a wetland alive with birds at sunrise, a wildflower growing beside a mountain path, an unexpected wildlife sighting, or a landscape you had never heard of before planning the trip.

National Park Field Guide is designed to help you find those places too.

🌱 Explore Parks Responsibly

National parks are places to enjoy, but they are also protected landscapes.

Stay on designated trails where required, respect closures, keep a safe distance from wildlife, follow food-storage regulations, pack out your trash, and leave natural and cultural objects where you find them.

Conditions and regulations can change because of weather, wildfire, flooding, wildlife activity, seasonal closures, construction, or conservation needs. Before traveling, always check current information from the agency responsible for managing the park.

Responsible travel protects the landscape while making the experience better for the people who visit after you.
