1. 1

   A century of visits to US national parks

   • This briefing looks at how many people visit US national parks and how that has changed over a century.
   • It is written for park planners, journalism students and general readers.
   • We cover counting methods, long-term trends, popular parks and the pressures that follow.
   • We close with what the numbers mean for planning.
2. 2

   From counting methods to closures: the route of this briefing

   • We begin with the map of park units and how visits are counted.
   • Next come the long-term trend and the ten most-visited parks.
   • Then we look at seasons, crowding, roads, lodging and staffing.
   • Finally we cover safety, closures and funding, ending with lessons for planners.
3. 3

   433 park units on one map

   • The National Park System has 433 park units, as shown on the map.
   • Units include more than national parks, such as monuments, seashores and historic sites.
   • Only a subset carry the formal title of national park.
   • Visit totals for the system cover all units, not just the best-known parks.
4. 4

   How visits are counted

   • Park staff count recreation visits, meaning entries by people for recreation.
   • Counts rely on tools such as vehicle counters, entrance data and visitor surveys.
   • Methods differ by park, so comparisons need care.
   • A visit is not a unique person, since one person can visit many times.
5. 5

   From 3 million visits in 1930 to a record 332 million in 2024

   • Recreation visits rose from 3.0 million in 1930 to 331.9 million in 2024.
   • Growth was steady, reaching 71.6 million in 1960 and 168.1 million in 1970.
   • Visits passed 285 million in 2000 and were 281.3 million in 2010.
   • The 2020 figure fell to 237.1 million, then 2024 set a record.

   The ten most-visited national parks in 2024

   • Great Smoky Mountains led in 2024 with 12.19 million recreation visits.
   • Zion followed at 4.95 million, just ahead of Grand Canyon at 4.92 million.
   • Yellowstone had 4.74 million, Rocky Mountain 4.15 million and Yosemite 4.12 million.
   • Glacier was tenth with 3.21 million, so the leader had far more than any other.

7. 7

   Seasons and peak months

   • Visits cluster in warm months at many parks, with summer as the common peak.
   • Some parks peak in other seasons, depending on climate and access.
   • Peak months strain staff, parking and lodging far more than the annual total suggests.
   • Monthly data helps planners match staffing to demand.
8. 8

   Crowding at popular trailheads

   • Popular trailheads can fill early in the day at busy parks.
   • Crowding affects safety, visitor experience and trail and soil condition.
   • Tools include timed entry, trailhead quotas and shuttle links (examples).
   • Journalists should ask which trails, and when, rather than relying on park totals.
9. 9

   Roads, shuttles and parking

   • Most visitors arrive by car, so roads and parking set practical limits.
   • Full lots can lead to closures at entrances or roadside crowding.
   • Shuttles can move more people with fewer vehicles in tight valleys.
   • Road repair is costly and often disrupts access.
10. 10

    Lodging and campgrounds

    • Lodging and campgrounds have fixed capacity, while day visits can grow.
    • Popular campsites are often booked well ahead through reservation systems.
    • Limited beds inside parks push overnight visitors into nearby gateway towns.
    • Planners track overnight stays separately from recreation visits.
11. 11

    Staff and volunteers

    • Rangers, maintenance crews and volunteers keep parks open and safe.
    • Seasonal hiring lets parks scale up for busy months.
    • Volunteers support programs such as information desks and trail work.
    • Staffing that lags visitor growth shows up in service and upkeep.
12. 12

    Wildlife and visitor safety

    • Visitors share parks with wild animals, so distance rules matter.
    • Common risks include heat, falls, water hazards and getting lost.
    • Crowds raise the odds of incidents and slow emergency response in remote areas.
    • Clear safety messaging and preparation reduce harm.
13. 13

    Weather and fire closures

    • Wildfire, floods, storms and snow can close roads, trails or whole parks.
    • Closures change visit counts and can shift crowds to other areas.
    • Smoke and heat affect health, even where parks stay open.
    • Planners need contingency plans and quick public alerts.
14. 14

    Paying for upkeep

    • Upkeep is paid for through a mix of federal funding and entrance and other fees.
    • Higher use adds wear on roads, buildings, trails and restrooms.
    • Deferred maintenance is a long-running concern for the system.
    • Visit data helps justify where money and staff are needed.
15. 15

    What the visit numbers mean for park planners

    • Visits reached a record 331.9 million in 2024, so demand keeps rising.
    • Use is uneven: a few parks and months carry much of the crowding.
    • Planners should pair visit counts with capacity data on roads, trails and lodging.
    • Readers should check how a number was counted before drawing conclusions.
