How Crowded Is Valley Forge National Historical Park in July?

July runs about 1.5× Valley Forge National Historical Park's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in July.

In a typical July the park sees about 244,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Valley Forge; January, the quietest, runs only about 0.4× the average — a 3-to-1 swing between high and low season.

On our Best Time to Visit score July rates 41/100 ("Poor"), versus the top-rated September at 63/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical July weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 88°F and an overnight low around 66°F, with about 4.6" of precipitation.

That average of about 77°F is warm enough that midday heat is worth planning around.

July 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 14.6 hours of daylight in July 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 July may feel a touch quieter than it once did.
