How Crowded Is Lake Roosevelt National Recreation Area in December?

December runs about 0.3× Lake Roosevelt National Recreation Area's average month, which makes it a very quiet month here — roughly 3% of the park's yearly visitors come in December.

In a typical December the park sees about 34,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Lake Roosevelt; by contrast July, the busiest, runs about 2.5× the average — so December is the easiest time to have the place largely to yourself.

On our Best Time to Visit score December rates 73/100 ("Good"), versus the top-rated May at 79/100 — the best overall balance of crowds and daylight.

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

You'll have about 8.2 hours of daylight in December to explore — near the year-round minimum.

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 December may feel a touch quieter than it once did.
