How Crowded Is Ste. Geneviève National Historical Park in October?

October runs about 0.9× Ste. Geneviève National Historical Park's average month, which makes it an average month here — roughly 7% of the park's yearly visitors come in October.

In a typical October the park sees roughly 1,500 recreation visits, based on National Park Service monthly counts from 2024 to 2025.

That makes October the 8th-busiest of the park's twelve months, sitting between the August peak (1.7×) and the January low (0.2×).

On our Best Time to Visit score October rates 56/100 ("Fair") — the single best-rated month at Ste. Geneviève, balancing crowds against weather and daylight.

Typical October weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 70°F and an overnight low around 46°F, with about 3.1" of precipitation.

That average of about 58°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 35% of annual visitors, choosing October instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 11 hours of daylight in October to explore — between the 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 16,525 recreation visits, down 30.8% from 23,893 in 2024.
