How Crowded Is Catoctin Mountain Park in December?

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

In a typical December the park sees about 18,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes December the 10th-busiest of the park's twelve months, sitting between the October peak (1.4×) and the February low (0.5×).

On our Best Time to Visit score December rates 45/100 ("Fair"), versus the top-rated May at 62/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical December weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 43°F and an overnight low around 28°F, with about 3.5" of precipitation.

That average of about 36°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 31% 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 9.2 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 460,857 recreation visits, up 21.1% from 380,681 in 2024.

Across the past decade overall visitation has risen about 40.8%, so a December visit is likely to feel busier than it did a few years ago.
