How Crowded Is Saint Croix National Scenic Riverway in June?

June runs about 2.3× Saint Croix National Scenic Riverway's average month, which makes it a very busy month here — roughly 19% of the park's yearly visitors come in June.

In a typical June the park sees about 148,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes June the 3rd-busiest of the park's twelve months, sitting between the July peak (3.1×) and the December low (0×).

On our Best Time to Visit score June rates 62/100 ("Good") — the single best-rated month at Saint Croix, balancing crowds against weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 77°F and an overnight low around 56°F, with about 4.2" 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 66% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 15.5 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2025 drew 852,296 recreation visits, down 5.4% from 900,828 in 2024.

Across the past decade overall visitation has risen about 20.9%, so a June visit is likely to feel busier than it did a few years ago.
