How Crowded Is Crater Lake National Park in April?

April runs about 0.3× Crater Lake National Park's average month, which makes it a very quiet month here — roughly 2% of the park's yearly visitors come in April.

In a typical April the park sees about 16,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes April the 7th-busiest of the park's twelve months, sitting between the July peak (3.4×) and the January low (0.1×).

On our Best Time to Visit score April rates 47/100 ("Fair"), versus the top-rated August at 48/100 — 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 40°F and an overnight low around 23°F, with about 6.2" of precipitation and roughly 49" of snow.

That average of about 32°F is cold, with winter conditions likely on higher ground.

Because June, July and August together draw about 65% 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 13.2 hours of daylight in April to explore — between the 8.8-hour midwinter low and the 15.2-hour summer high.

Park-wide, 2025 drew 632,242 recreation visits, up 25.2% from 504,942 in 2024.

Across the past decade overall visitation has eased about 19.4%, so April may feel a touch quieter than it once did.
