How Crowded Is Harpers Ferry National Historical Park in October?

October runs about 1.6× Harpers Ferry National Historical Park's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in October.

In a typical October the park sees about 49,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes October the 2nd-busiest of the park's twelve months, sitting between the July peak (1.7×) and the January low (0.1×).

On our Best Time to Visit score October rates 32/100 ("Poor"), versus the top-rated September at 57/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical October weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 67°F and an overnight low around 42°F, with about 3.4" of precipitation.

That average of about 54°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 38% 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 10.9 hours of daylight in October to explore — between the 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2025 drew 537,876 recreation visits, up 10.2% from 488,049 in 2024.

Across the past decade overall visitation has risen about 46.8%, so a October visit is likely to feel busier than it did a few years ago.
