How Crowded Is Fort Union National Monument in April?

April runs about 1× Fort Union National Monument's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in April.

In a typical April the park sees about 870 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes April the 8th-busiest of the park's twelve months, sitting between the June peak (1.7×) and the January low (0.3×).

On our Best Time to Visit score April rates 47/100 ("Fair"), versus the top-rated August at 65/100 — best overall balance of crowds, weather and daylight.

Typical April weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 67°F and an overnight low around 29°F, with about 0.8" of precipitation and roughly 2" of snow.

That average of about 48°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 37% of annual visitors, choosing April instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.9 hours of daylight in April to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

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 April may feel a touch quieter than it once did.
