How Crowded Is Jewel Cave National Monument in March?

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

In a typical March the park sees roughly 2,100 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 7th-busiest of the park's twelve months, sitting between the July peak (3.5×) and the January low (0×).

On our Best Time to Visit score March rates 45/100 ("Fair"), versus the top-rated May at 67/100 — best overall balance of crowds, weather and daylight.

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 47°F and an overnight low around 23°F, with about 0.8" of precipitation and roughly 5" of snow.

That average of about 35°F is cool, so layers and a shorter daylight window matter.

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

You'll have about 11.6 hours of daylight in March 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 March may feel a touch quieter than it once did.
