How Crowded Is Upper Delaware Scenic & Recreational River in June?

June runs about 1.5× Upper Delaware Scenic & Recreational River's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in June.

In a typical June the park sees about 36,000 recreation visits, based on National Park Service monthly counts from 1980 to 2025.

That makes June the 4th-busiest of the park's twelve months, sitting between the July peak (2.9×) and the December low (0.2×).

On our Best Time to Visit score June rates 69/100 ("Good") — the single best-rated month at Upper Delaware, balancing crowds against weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 78°F and an overnight low around 54°F, with about 4.8" of precipitation.

That average of about 66°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 59% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 15 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2025 drew 380,245 recreation visits, up 0.8% from 377,061 in 2024.

Across the past decade overall visitation has risen about 34.9%, so a June visit is likely to feel busier than it did a few years ago.
