How Crowded Is Jewel Cave National Monument in January?

January runs about 0× Jewel Cave National Monument's average month, which makes it a very quiet month here — roughly 0% of the park's yearly visitors come in January.

In a typical January the park sees about 280 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the quietest month of the year at Jewel Cave; by contrast July, the busiest, runs about 3.5× the average — so January is the easiest time to have the place largely to yourself.

On our Best Time to Visit score January rates 42/100 ("Poor"), versus the top-rated May at 67/100 — best overall balance of crowds, weather and daylight.

Typical January weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 36°F and an overnight low around 11°F, with about 0.4" of precipitation and roughly 6" of snow.

That average of about 23°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 71% of annual visitors, choosing January instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 9.1 hours of daylight in January to explore — between the 8.7-hour midwinter low and the 15.2-hour summer high.

Park-wide, 2024 drew 145,332 recreation visits, up 19.6% from 121,536 in 2023.

Across the past decade overall visitation has eased about 20.1%, so January may feel a touch quieter than it once did.
