How Crowded Is Natural Bridges National Monument in December?

December runs about 0.2× Natural Bridges National Monument's average month, which makes it a very quiet month here — roughly 2% of the park's yearly visitors come in December.

In a typical December the park sees roughly 1,400 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes December the 11th-busiest of the park's twelve months, sitting between the May peak (2.2×) and the January low (0.2×).

On our Best Time to Visit score December rates 42/100 ("Poor"), versus the top-rated August at 75/100 — 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 39°F and an overnight low around 20°F, with about 1.1" of precipitation and roughly 8" of snow.

That average of about 30°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 27% 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 9.4 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2025 drew 70,400 recreation visits, down 7% from 75,680 in 2024.

Across the past decade overall visitation has eased about 24.4%, so December may feel a touch quieter than it once did.
