How Crowded Is Prince William Forest Park in January?

January runs about 0.6× Prince William Forest Park's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in January.

In a typical January the park sees about 16,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Prince William Forest; by contrast July, the busiest, runs about 1.3× the average — so January is the easiest time to have the place largely to yourself.

On our Best Time to Visit score January rates 43/100 ("Poor"), versus the top-rated April at 59/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical January weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 45°F and an overnight low around 28°F, with about 2.7" of precipitation and roughly 4" of snow.

That average of about 37°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 32% of annual visitors, choosing January instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 9.6 hours of daylight in January to explore — near the year-round minimum.

Park-wide, 2025 drew 339,015 recreation visits, down 4.6% from 355,196 in 2024.
