How Crowded Is Devils Tower National Monument in December?

December runs about 0.1× Devils Tower National Monument'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 roughly 3,400 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 July peak (2.9×) and the January low (0.1×).

On our Best Time to Visit score December rates 41/100 ("Poor"), versus the top-rated May at 63/100 — 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 35°F and an overnight low around 9°F, with about 0.7" of precipitation and roughly 10" of snow.

That average of about 22°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 67% 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 8.6 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 515,303 recreation visits, down 4.7% from 540,890 in 2024.

Across the past decade overall visitation has risen about 8.6%, so a December visit is likely to feel busier than it did a few years ago.
