How Crowded Is George Rogers Clark National Historical Park in March?

March runs about 0.5× George Rogers Clark National Historical Park's average month, which makes it a very quiet month here — roughly 4% of the park's yearly visitors come in March.

In a typical March the park sees roughly 5,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 9th-busiest of the park's twelve months, sitting between the May peak (2.9×) and the January low (0.2×).

On our Best Time to Visit score March rates 56/100 ("Fair"), versus the top-rated October at 66/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 55°F and an overnight low around 33°F, with about 3.6" of precipitation.

That average of about 44°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 38% of annual visitors, choosing March instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 11.7 hours of daylight in March to explore — between the 9.3-hour midwinter low and the 14.7-hour summer high.

Park-wide, 2025 drew 113,397 recreation visits, down 31.9% from 166,621 in 2024.

Across the past decade overall visitation has risen about 18.6%, so a March visit is likely to feel busier than it did a few years ago.
