How Crowded Is Fort Union National Monument in June?

June runs about 1.7× Fort Union National Monument's average month, which makes it a very busy month here — roughly 14% of the park's yearly visitors come in June.

In a typical June the park sees roughly 1,500 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Fort Union; January, the quietest, runs only about 0.3× the average — a 5-to-1 swing between high and low season.

On our Best Time to Visit score June rates 52/100 ("Fair"), versus the top-rated August at 65/100 — best overall balance of crowds, weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 85°F and an overnight low around 46°F, with about 1.7" 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 37% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.4 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2024 drew 9,217 recreation visits, down 3.7% from 9,570 in 2023.

Across the past decade overall visitation has eased about 12.5%, so June may feel a touch quieter than it once did.
