How Crowded Is Valley Forge National Historical Park in June?

June runs about 1.4× Valley Forge National Historical Park's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in June.

In a typical June the park sees about 225,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes June the 2nd-busiest of the park's twelve months, sitting between the July peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score June rates 52/100 ("Fair"), versus the top-rated September at 63/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 83°F and an overnight low around 61°F, with about 3.9" of precipitation.

That average of about 72°F is a comfortable range for hiking and being outdoors all day.

June falls inside the park's busiest stretch: June, July and August together pull about 35% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.8 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2025 drew 1,819,086 recreation visits, down 2.5% from 1,866,480 in 2024.

Across the past decade overall visitation has eased about 18.9%, so June may feel a touch quieter than it once did.
