How Crowded Is Fort Donelson National Battlefield in September?

September runs about 1.4× Fort Donelson National Battlefield's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in September.

In a typical September the park sees about 24,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Fort Donelson; December, the quietest, runs only about 0.6× the average — a 2-to-1 swing between high and low season.

On our Best Time to Visit score September rates 45/100 ("Fair"), versus the top-rated July at 55/100 — pleasant weather with noticeably thinner crowds (shoulder season).

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 3.6" 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 27% 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 151,151 recreation visits, down 9% from 166,026 in 2024.

Across the past decade overall visitation has eased about 24.8%, so September may feel a touch quieter than it once did.
