National Park Visitor Rank: Top 10 Most Visited Parks

The most visited U.S. national park is Great Smoky Mountains National Park, which has held the top spot for decades. In 2023, it recorded over 13 million recreation visits, more than double the second-place park.

Why Great Smoky Mountains Leads the Rankings

Great Smoky Mountains National Park sits on the border of Tennessee and North Carolina, within a day’s drive for about half the U.S. population. Its free entry (no entrance fee) removes a barrier that other parks have. The park’s 800 miles of trails, historic log cabins, and synchronous firefly displays attract families, hikers, and nature lovers year-round. Unlike many western parks, it stays accessible in all seasons, with lower elevations remaining mild in winter.

The Top 10 Most Visited Parks (2023 Data)

The National Park Service (NPS) publishes annual recreation visit numbers. The 2023 figures show a clear pattern: eastern and easily accessible parks dominate, while iconic western parks like Yellowstone and Yosemite rank lower than many assume.

1. Great Smoky Mountains (TN/NC) – 13,297,647 visits
2. Grand Canyon (AZ) – 4,733,705 visits
3. Zion (UT) – 4,623,238 visits
4. Yellowstone (WY/MT/ID) – 4,501,382 visits
5. Rocky Mountain (CO) – 4,115,812 visits
6. Yosemite (CA) – 3,897,070 visits
7. Acadia (ME) – 3,879,045 visits
8. Grand Teton (WY) – 3,417,106 visits
9. Joshua Tree (CA) – 3,270,593 visits
10. Olympic (WA) – 2,947,503 visits

These numbers come from the NPS Visitor Use Statistics database. They reflect recreation visits, which count each person entering the park, not overnight stays or unique individuals.

How the National Park Service Counts Visitors

The NPS uses several methods to estimate visits, not exact turnstile counts. Most parks use traffic counters at entrances, but some rely on trailhead registers, backcountry permits, or aerial surveys. For parks without gates (like Great Smoky Mountains, which has many open roads), the NPS uses a statistical model based on traffic counts and sampling. This means numbers are estimates, though they are consistent enough for year-over-year comparisons.

One common misconception is that visitation equals popularity in quality. A high rank often reflects location and accessibility more than scenic value. For example, Great Smoky Mountains is free and centrally located; Joshua Tree is close to Los Angeles; Acadia is a short drive from Boston. Parks like Gates of the Arctic (Alaska) or Isle Royale (Michigan) require significant effort to reach, so they see fewer than 30,000 visits annually.

Why Rankings Change Over Time

Visitation ranks are not static. The COVID-19 pandemic caused a surge in outdoor recreation, boosting many parks in 2020–2021. Some parks, like Zion and Rocky Mountain, saw record numbers as international travel dropped and Americans explored domestic destinations. Conversely, parks that rely on international tourists, such as Hawaii Volcanoes, dropped in rank during that period.

Long-term trends also shift rankings. Climate change has extended warm seasons in northern parks, increasing visits to places like Glacier and Acadia. Social media virality can spike visits to specific spots, as seen with the “Mermaid Pools” in Channel Islands or the wave of visitors to Arches after it appeared in films. The NPS has implemented timed entry reservations in some parks (e.g., Arches, Rocky Mountain, Yosemite) to manage crowds, which can affect visitor counts.

How to Use Visitor Rankings When Planning a Trip

If you want to avoid crowds, the top 10 list is not your best guide. Instead, look at the least visited parks or visit popular ones in off-peak times. For example, Yellowstone in May or September is far less crowded than July. Great Smoky Mountains sees its peak in October (fall colors) and June (summer break).

Consider these factors when choosing a park:

Entrance fee: The America the Beautiful Pass covers all parks; some parks have free days.
Reservations: Check if the park requires timed entry or camping reservations.
Seasonality: High-elevation parks like Rocky Mountain may have snow into June; desert parks like Joshua Tree are best in spring/fall.
Accessibility: How many airports are nearby? Is public transit available?

If your goal is solitude, consider parks with fewer than 1 million visits, such as North Cascades (WA), Great Basin (NV), or Congaree (SC). These often offer comparable beauty without the queues.

Common Problems with High Visitation

High visitation brings real challenges. Traffic jams at entrances, full parking lots, and crowded trails degrade the experience. It also strains park infrastructure and wildlife. In 2023, Zion implemented a shuttle system to reduce congestion, and Arches now requires timed entry from April to October. Visitors often complain about:

Long lines at popular viewpoints (e.g., Horseshoe Bend, which is not even a national park but a Glen Canyon recreation area).
Litter and trampled vegetation from off-trail hiking.
Wildlife habituation – animals like bears in Smokies or bison in Yellowstone become accustomed to humans, leading to dangerous encounters.

The NPS encourages visiting “shoulder seasons” (spring/fall) and lesser-known areas within a park. For instance, in Yellowstone, the Lamar Valley sees fewer crowds than Old Faithful.

Comparison with State Parks and Other Public Lands

National parks are not the only public lands. State parks often offer similar scenery with fewer visitors. For example, New York’s Adirondack Park is larger than any national park in the lower 48 and has no entrance fee. Many national monuments, like Dinosaur National Monument or Bears Ears, have lower visitation but rich cultural and natural features.

If you want to avoid crowds entirely, consider National Wildlife Refuges or Bureau of Land Management (BLM) areas. These often have no fees and few amenities, but they provide a raw, uncrowded experience. The key is to match the type of land to your needs: national parks have the most infrastructure and services, while other designations offer more solitude.

Costs and Budget Considerations

Visiting a national park involves more than the entrance fee. The average family trip includes lodging, food, and activities. The NPS does not set lodging prices, but in-park hotels are often expensive and book months ahead. Camping is cheaper: most campsites cost $20–$35 per night. Entrance fees range from $15 to $35 per vehicle, depending on the park. An annual pass costs $80 and covers all federal lands.

Hidden costs include:

Transportation to remote parks (flights to Alaska or Montana).
Equipment rentals (e.g., bear canisters in Yosemite are free but required).
Guided tours or permits for special activities (e.g., climbing in Yosemite requires a permit).

To save money, visit parks on free entrance days (typically 5–6 days per year, such as Martin Luther King Jr. Day and Veterans Day), or choose parks with no entrance fee like Great Smoky Mountains.

Safety and Etiquette in Crowded Parks

Crowds increase safety risks. On busy trails, keep to the right, yield to uphill hikers, and do not block the path. Wildlife encounters are more likely when animals are habituated to humans. Always keep at least 100 yards from bears and wolves, and 25 yards from bison and elk. In 2023, multiple visitors were injured by bison in Yellowstone for approaching too closely.

Other safety tips:

Carry bear spray in grizzly country (Yellowstone, Glacier, Grand Teton).
Stay on designated trails – in thermal areas like Yellowstone, the ground can be thin and boiling.
Pack out all trash – crowded parks have overflowing bins.
Check weather forecasts; lightning is a top killer in parks like Rocky Mountain.

If you visit a park with timed entry, arrive early to avoid missing your slot. Follow all posted signs and respect closures, especially for wildlife protection or trail maintenance.

Frequently Asked Questions

Which national park has the most visitors every year?

Great Smoky Mountains National Park has been the most visited every year since at least 1940, except for a few years during WWII. Its free entry, central location, and mild climate keep it at the top.

Why is Great Smoky Mountains so popular despite not having iconic landmarks like Old Faithful?

Its popularity stems from accessibility and free entry. It is within a day’s drive of major cities like Atlanta, Nashville, and Charlotte. It also offers diverse activities: hiking, fishing, historic structures, and wildlife viewing. Many visitors come for short trips, not just destination vacations.

What is the least visited national park?

Gates of the Arctic National Park in Alaska is typically the least visited, with under 15,000 visits annually. It has no roads or trails, and access is only by plane or long hikes. Other remote parks like Lake Clark and Isle Royale also see very few visitors.

How do I find current visitor numbers?

The National Park Service publishes annual and monthly visitation statistics on its website (nps.gov). You can download data by park, year, and month. The most recent full year is usually available by early spring of the following year.

Do timed entry reservations reduce visitor numbers?

Timed entry systems cap the number of visitors per day, but they do not necessarily lower total annual visits. They spread crowds more evenly and reduce congestion. For example, Arches saw similar annual totals after implementing the system, but wait times dropped.

Which park has the highest visitor density per acre?

Urban parks like Gateway Arch (St. Louis) or Hot Springs (Arkansas) have very high density because they are small and in cities. Among large parks, Zion often has the highest density due to its narrow canyon and high visitation.
