How Crowded Is Aztec Ruins National Monument in December?

December runs about 0.6× Aztec Ruins National Monument'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 roughly 2,300 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 (1.7×) and the January low (0.3×).

On our Best Time to Visit score December rates 36/100 ("Poor"), versus the top-rated August 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 46°F and an overnight low around 18°F, with about 0.7" of precipitation and roughly 2" of snow.

That average of about 32°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 36% 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 9.5 hours of daylight in December to explore — near the year-round minimum.

Park-wide, 2024 drew 40,019 recreation visits, down 15.8% from 47,554 in 2023.

Across the past decade overall visitation has eased about 20.4%, so December may feel a touch quieter than it once did.
