How Crowded Is Cumberland Gap National Historical Park in September?

September runs about 1.1× Cumberland Gap National Historical Park's average month, which makes it an average month here — roughly 10% of the park's yearly visitors come in September.

In a typical September the park sees about 72,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 6th-busiest of the park's twelve months, sitting between the October peak (1.4×) and the January low (0.5×).

On our Best Time to Visit score September rates 57/100 ("Fair") — the single best-rated month at Cumberland Gap, balancing crowds against weather and daylight.

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 79°F and an overnight low around 55°F, with about 3.8" of precipitation.

That average of about 67°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 32% 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 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2025 drew 765,010 recreation visits, up 4.9% from 729,249 in 2024.
