How Crowded Is Antietam National Battlefield in March?

March runs about 0.6× Antietam National Battlefield's average month, which makes it a quiet month here — roughly 5% of the park's yearly visitors come in March.

In a typical March the park sees about 13,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 10th-busiest of the park's twelve months, sitting between the July peak (2×) and the January low (0.2×).

On our Best Time to Visit score March rates 47/100 ("Fair"), versus the top-rated September at 62/100 — 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 53°F and an overnight low around 29°F, with about 3.7" of precipitation.

That average of about 41°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 39% 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 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2024 drew 197,340 recreation visits, up 28.5% from 153,560 in 2023.

Across the past decade overall visitation has eased about 60.5%, so March may feel a touch quieter than it once did.
