How Crowded Is Fort Union Trading Post National Historic Site in July?

July runs about 2.2× Fort Union Trading Post National Historic Site's average month, which makes it a very busy month here — roughly 18% of the park's yearly visitors come in July.

In a typical July the park sees roughly 2,300 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes July the 2nd-busiest of the park's twelve months, sitting between the June peak (3.6×) and the January low (0.1×).

On our Best Time to Visit score July rates 68/100 ("Good"), versus the top-rated August at 71/100 — best overall balance of crowds, weather and daylight.

Typical July weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 85°F and an overnight low around 57°F, with about 2.5" of precipitation.

That average of about 71°F is a comfortable range for hiking and being outdoors all day.

July falls inside the park's busiest stretch: June, July and August together pull about 65% 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 July to explore — between the 8.2-hour midwinter low and the 15.8-hour summer high.

Park-wide, 2024 drew 12,028 recreation visits, down 7.1% from 12,942 in 2023.

Across the past decade overall visitation has eased about 23.2%, so July may feel a touch quieter than it once did.
