How Crowded Is Manassas National Battlefield Park in May?

In a typical May the park sees about 48,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

On our Best Time to Visit score May rates 64/100 ("Good") — the single best-rated month at Manassas, balancing crowds against weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 74°F and an overnight low around 54°F.

That average of about 64°F is a comfortable range for hiking and being outdoors all day.
