How Crowded Is Aniakchak National Monument & Preserve in December?

December runs about 0.1× Aniakchak National Monument & Preserve's average month, which makes it a very quiet month here — roughly 1% of the park's yearly visitors come in December.

In a typical December the park sees about 10 recreation visits, based on National Park Service monthly counts from 1989 to 2025.

That makes December the 8th-busiest of the park's twelve months, sitting between the September peak (3.7×) and the February low (0.1×).

On our Best Time to Visit score December rates 40/100 ("Poor"), versus the top-rated June at 67/100 — best overall balance of crowds, weather and daylight.

Typical December weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 27°F and an overnight low around 12°F, with about 2.1" of precipitation.

That average of about 20°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 49% 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 6.5 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 1994 drew 1,193 recreation visits, down 25.1% from 1,593 in 1993.

Across the past decade overall visitation has risen about 60.8%, so a December visit is likely to feel busier than it did a few years ago.
