How Crowded Is Hopewell Furnace National Historic Site in March?

March runs about 0.7× Hopewell Furnace National Historic Site's average month, which makes it a quiet month here — roughly 6% of the park's yearly visitors come in March.

In a typical March the park sees roughly 2,900 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 August peak (1.6×) and the January low (0.3×).

On our Best Time to Visit score March rates 49/100 ("Fair"), versus the top-rated October at 47/100 — 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 49°F and an overnight low around 31°F.

That average of about 40°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 37% 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 9.1-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2024 drew 48,776 recreation visits, down 10.2% from 54,293 in 2023.
