National Parks: A Guide to the Best Parks and How to Plan Your Visit

The US National Park System spans 63 designated national parks (plus hundreds of other protected sites), offering everything from dramatic canyons to volcanic islands to ancient redwood forests. This guide covers the most popular parks, how to plan a visit, and what you need to know about passes and fees.

How Many National Parks Are There?

The US has 63 official national parks, spread across more than half the states, alongside hundreds of additional national monuments, historic sites, seashores, and other protected areas managed by the National Park Service. California and Alaska both have the largest number of national parks of any single state.

The Most Popular US National Parks

Yellowstone was the first national park in the world, known for geothermal features like Old Faithful, dramatic canyons, and abundant wildlife including bison and grizzly bears.
Grand Canyon offers one of the most dramatic landscapes in the country, with rim viewpoints, hiking trails into the canyon itself, and river rafting through it.
Yosemite is famous for towering granite cliffs, waterfalls, and giant sequoia groves, with Yosemite Valley as its most iconic and heavily visited area.
Zion is known for narrow slot canyons, dramatic red rock formations, and popular hikes like Angels Landing and The Narrows.
Glacier National Park offers alpine scenery along the famous Going-to-the-Sun Road, with extensive hiking trails through mountain and glacier terrain.
Great Smoky Mountains is the most visited national park in the country, known for its accessible location, extensive trail network, and abundant wildlife.
Acadia offers rugged Atlantic coastline, granite peaks, and forested trails in Maine, a popular choice for East Coast visitors.
Rocky Mountain National Park offers high-altitude alpine terrain and abundant wildlife within a relatively accessible drive from Denver.

National Parks by Region

California is home to Yosemite, Sequoia, Kings Canyon, Joshua Tree, Death Valley, Redwood, Pinnacles, and Channel Islands — the most of any state.

Utah has five national parks (often called the “Mighty Five”): Zion, Bryce Canyon, Arches, Canyonlands, and Capitol Reef, all within reasonable driving distance of each other.

Alaska contains several of the largest and least-visited national parks, including Denali, Gates of the Arctic, and Wrangell-St. Elias, offering genuinely remote wilderness experiences.

East Coast parks include Acadia (Maine), Shenandoah (Virginia), and the Great Smoky Mountains (Tennessee/North Carolina), all offering more accessible options for visitors without extensive travel time.

Arizona and the Southwest feature the Grand Canyon, Saguaro, and Petrified Forest, showcasing the region’s desert and canyon landscapes.

How to Plan a National Park Trip

Check entrance fees and consider an annual pass. The “America the Beautiful” annual pass covers entrance fees at all national parks and is generally worthwhile if you’re visiting more than two or three parks in a year.
Book lodging and campsites well in advance for popular parks. In-park lodging at destinations like Yosemite, Zion, and Glacier often books up months ahead, especially during peak summer season.
Check for vehicle reservation requirements. Some of the most popular parks, including Glacier and parts of Yosemite, require timed vehicle entry reservations during peak season — booking these ahead of your trip is essential.
Plan around shoulder season if you want to avoid the biggest crowds. Visiting just before or after a park’s peak season often means significantly smaller crowds with only a modest trade-off in weather or accessibility.
Research specific trail and activity requirements, since some popular hikes (like Angels Landing in Zion) now require advance permits due to high demand.

National Park Passes for Seniors and Others

Senior pass — a discounted or free lifetime pass available to US citizens or permanent residents 62 and older, covering entrance fees at all national parks.
Access pass — a free lifetime pass available to US citizens or permanent residents with a permanent disability.
4th grade pass (Every Kid Outdoors) — a free annual pass available to US fourth-grade students and their families, covering entrance to national parks for the school year.
Standard annual pass — available to anyone, covering entrance fees at all national parks and federal recreation sites for one year from purchase.

Best Time to Visit National Parks

Summer (June–August) offers the most reliable access and full services at most parks, but also the biggest crowds and highest prices, particularly at high-altitude parks that are only fully accessible during warmer months.
Spring and fall shoulder seasons offer a strong balance of good weather, thinner crowds, and lower lodging costs at many parks, particularly desert parks like Zion and the Grand Canyon where summer heat can be intense.
Winter visits to accessible parks can offer a genuinely different, quieter experience, though many facilities, roads, and trails close or become significantly harder to access.

International National Parks Worth Knowing

Beyond the US, several international national parks are frequently sought out by travelers:

Banff National Park in Canada offers iconic Rocky Mountain scenery and turquoise glacial lakes.
Torres del Paine in Chile is one of South America’s premier hiking and wilderness destinations.
Serengeti and Kruger National Parks in Tanzania and South Africa offer some of the world’s best wildlife safari experiences.
Fiordland National Park in New Zealand features dramatic fjords and is home to Milford Sound.

Frequently Asked Questions

Do I need a reservation to visit a national park? Standard entry doesn’t typically require a reservation, but several of the most popular parks (including Glacier, and parts of Yosemite and Arches) require a separate timed vehicle entry permit during peak season — checking specific park requirements before your visit is essential.

Is the annual national parks pass worth it? If you’re planning to visit more than two or three parks within a year, the annual pass typically pays for itself compared to paying individual entrance fees, and it also covers many other federal recreation sites beyond national parks.

What’s the most visited national park in the US? Great Smoky Mountains National Park consistently ranks as the most visited, partly due to its free entry and accessible location within a day’s drive of a large portion of the US population.

Which national parks are best for beginners or first-time visitors? Parks with well-developed infrastructure, clear trail systems, and shorter hikes — like Zion, Acadia, or Rocky Mountain National Park — tend to be more approachable for visitors new to national park travel than more remote or rugged parks.

How far in advance should I book lodging inside a national park? For popular parks during peak season, booking 6-12 months ahead is often necessary, since in-park lodging is limited and demand consistently outpaces availability at the most sought-after locations.
