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

March runs about 0.2× Fort Union Trading Post National Historic Site's average month, which makes it a very quiet month here — roughly 2% of the park's yearly visitors come in March.

In a typical March the park sees about 190 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes March the 8th-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 March rates 45/100 ("Fair"), versus the top-rated August at 71/100 — best overall balance of crowds, weather and daylight.

Typical March weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 42°F and an overnight low around 19°F, with about 0.5" of precipitation and roughly 4" of snow.

That average of about 31°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 65% of annual visitors, choosing March instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 11.6 hours of daylight in March 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 March may feel a touch quieter than it once did.
