How Crowded Is Russell Cave National Monument in September?

September runs about 1.1× Russell Cave National Monument's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in September.

In a typical September the park sees roughly 1,600 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 7th-busiest of the park's twelve months, sitting between the April peak (1.4×) and the January low (0.5×).

On our Best Time to Visit score September rates 58/100 ("Fair") — the single best-rated month at Russell Cave, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 82°F and an overnight low around 60°F, with about 4.4" of precipitation.

That average of about 71°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 30% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.2 hours of daylight in September to explore — between the 9.7-hour midwinter low and the 14.3-hour summer high.

Park-wide, 2024 drew 9,261 recreation visits, up 6.7% from 8,678 in 2023.

Across the past decade overall visitation has eased about 31.9%, so September may feel a touch quieter than it once did.
