How Crowded Is Theodore Roosevelt Inaugural National Historic Site in September?

September runs about 1.1× Theodore Roosevelt Inaugural National Historic Site'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 2,300 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 5th-busiest of the park's twelve months, sitting between the June peak (1.7×) and the January low (0.4×).

On our Best Time to Visit score September rates 48/100 ("Fair"), versus the top-rated January at 77/100 — the best overall balance of crowds and daylight.

Because June, July and August together draw about 35% 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 12.3 hours of daylight in September to explore — between the 8.8-hour midwinter low and the 15.1-hour summer high.

Park-wide, 2025 drew 26,787 recreation visits, down 11.1% from 30,141 in 2024.

Across the past decade overall visitation has eased about 17.5%, so September may feel a touch quieter than it once did.
