How Crowded Is Lewis and Clark National Historical Park in March?

March runs about 0.8× Lewis and Clark National Historical Park's average month, which makes it a quiet month here — roughly 7% of the park's yearly visitors come in March.

In a typical March the park sees about 17,000 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 July peak (1.9×) and the December low (0.4×).

On our Best Time to Visit score March rates 46/100 ("Fair"), versus the top-rated May at 59/100 — 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 53°F and an overnight low around 39°F, with about 7.9" of precipitation.

That average of about 46°F is cool, so layers and a shorter daylight window matter.

Because June, July and August together draw about 44% 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 8.4-hour midwinter low and the 15.6-hour summer high.

Park-wide, 2025 drew 244,195 recreation visits, down 8.6% from 267,118 in 2024.
