Least Crowded National Parks by Month, From NPS Visitor Counts

How we measured it

The NPS publishes monthly recreation visits for each park. For 24 popular parks, we took the 2024 numbers (the most recent full year with no gaps across our list) and compared each month with that park's busiest month. "Share of peak" means a month's visits as a percentage of the busiest month. You can explore any of the 24 in the crowd calendar.

Why counts, not opinions

Crowd advice is often based on impressions. The NPS monthly counts give a consistent measure across years and parks, even if each park's counting method has its own limits.

Total visits, 2024

The range is wide. Great Smoky Mountains recorded about 12.2 million recreation visits, Grand Canyon about 4.9 million and Zion about 4.9 million. At the other end, Lassen Volcanic had about 358,000, Crater Lake about 505,000 and Petrified Forest about 559,000.

Winter (December–February)

Most northern and mountain parks are at their lowest. In 2024 Glacier had about 14,000 visits in January versus about 792,000 in July. But the NPS notes most Yellowstone roads are closed to regular vehicles from early November to late April, and similar seasonal limits apply elsewhere. Quiet doesn't mean accessible.

Desert parks are the opposite. Joshua Tree, Death Valley and Everglades are in or near their busy season through winter and early spring.

Quieter winter picks among the 24: Zion (January had 20% of June's visits), Grand Canyon (January was its lowest month, about 32% of May) and Arches (January about 14% of May). Expect cold, and check for snow and ice on trails.

Spring (March–May)

Spring is peak season in the desert: Joshua Tree peaked in March 2024, Death Valley in April, and Arches, Canyonlands, Capitol Reef and Grand Canyon in May.

Quieter spring picks: northern parks before summer, such as Acadia (May at 40% of August), Rocky Mountain (May at 43% of July) and Yellowstone (May at 53% of July). Some roads and services may still be opening.

Summer (June–August)

Peak season for most of the list: Yellowstone, Glacier, Grand Teton, Rocky Mountain, Mount Rainier, Yosemite and Crater Lake all peaked in July 2024.

Quieter summer picks: desert parks. Joshua Tree's July was its lowest month (about 31% of March) and Death Valley's lowest was June. These are quiet for a reason: extreme heat. Grand Canyon rangers warn that inner canyon summer temperatures can exceed 110°F and strongly discourage hiking from 10 a.m. to 4 p.m. Read hiking in the heat first.

Fall (September–November)

September keeps most of summer's access with fewer people at northern parks: Glacier at 76% of July and Grand Teton at 75%. By October, Grand Teton fell to 35% and Glacier to 21%, as seasonal closures begin.

Some parks peak in fall: Great Smoky Mountains and Shenandoah were busiest in October 2024, and Bryce Canyon in September.

Quieter fall picks: Zion in November (51% of June) and Arches in November (40% of May).

Making a quiet month work

• Check access. Look up the park's road status and operating dates on nps.gov for your dates.
• Go midweek. Monthly totals hide weekend and holiday peaks, so a busy month can still have calm weekdays.
• Start early. Popular trailheads fill first.
• Use the daylight. Shoulder and winter days are short; use the park sunrise and sunset tool to plan.

Common questions

What is the least crowded big national park?

Among the 24 parks we track, Lassen Volcanic (about 358,000 recreation visits in 2024) and Crater Lake (about 505,000) had the fewest. Great Smoky Mountains had by far the most, about 12.2 million.

Is September a good month to avoid crowds?

At northern parks it's a good compromise. In 2024 September visits were 76% of July's at Glacier and 75% at Grand Teton, while most roads and facilities are usually still open.

Which parks are busiest in fall?

Great Smoky Mountains and Shenandoah both peaked in October in 2024. Bryce Canyon peaked in September.

Does the NPS publish daily crowd data?

The Visitor Use Statistics site publishes monthly and annual numbers. Daily and hourly busyness, like full parking lots, depends on weekends, holidays and weather.
