How Crowded Is John Muir National Historic Site in April?

April runs about 1.6× John Muir National Historic Site's average month, which makes it a busy month here — roughly 13% of the park's yearly visitors come in April.

In a typical April the park sees roughly 5,700 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at John Muir; December, the quietest, runs only about 0.7× the average — a 2-to-1 swing between high and low season.

On our Best Time to Visit score April rates 40/100 ("Poor"), versus the top-rated September at 85/100 — 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 71°F and an overnight low around 43°F, with about 1.3" of precipitation.

That average of about 57°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 27% 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 hours of daylight in April to explore — between the 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 38,384 recreation visits, down 16.1% from 45,753 in 2024.
