How Crowded Is Thaddeus Kosciuszko National Memorial in April?

April runs about 0.9× Thaddeus Kosciuszko National Memorial'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 380 recreation visits, based on National Park Service monthly counts from 1981 to 2025.

That makes April the 7th-busiest of the park's twelve months, sitting between the July peak (1.8×) and the January low (0.4×).

On our Best Time to Visit score April rates 60/100 ("Good"), versus the top-rated October at 55/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical April weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 66°F and an overnight low around 46°F, with about 4" of precipitation.

That average of about 56°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 39% 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 13.1 hours of daylight in April to explore — between the 9.2-hour midwinter low and the 14.8-hour summer high.

Park-wide, 2013 drew 1,682 recreation visits, down 17.8% from 2,045 in 2012.

Across the past decade overall visitation has eased about 49%, so April may feel a touch quieter than it once did.
