How Crowded Is Lake Roosevelt National Recreation Area in May?

May runs about 0.8× Lake Roosevelt National Recreation Area's average month, which makes it a quiet month here — roughly 7% of the park's yearly visitors come in May.

In a typical May the park sees about 88,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes May the 5th-busiest of the park's twelve months, sitting between the July peak (2.5×) and the December low (0.3×).

On our Best Time to Visit score May rates 79/100 ("Excellent") — the single best-rated month at Lake Roosevelt, balancing crowds against daylight.

Because June, July and August together draw about 54% of annual visitors, choosing May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 15 hours of daylight in May to explore — between the 8.2-hour midwinter low and the 15.8-hour summer high.

Park-wide, 2025 drew 1,183,757 recreation visits, up 8.5% from 1,091,489 in 2024.

Across the past decade overall visitation has eased about 12.4%, so May may feel a touch quieter than it once did.
