How Crowded Is Muir Woods National Monument in August?

August runs about 1.4× Muir Woods National Monument's average month, which makes it a busy month here — roughly 12% of the park's yearly visitors come in August.

In a typical August the park sees about 105,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the July peak (1.7×) and the February low (0.6×).

On our Best Time to Visit score August rates 64/100 ("Good"), versus the top-rated October at 72/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 83°F and an overnight low around 54°F, with about 0.1" of precipitation.

That average of about 68°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 36% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.5 hours of daylight in August to explore — between the 9.4-hour midwinter low and the 14.6-hour summer high.

Park-wide, 2025 drew 756,573 recreation visits, down 4.5% from 792,494 in 2024.

Across the past decade overall visitation has eased about 24.5%, so August may feel a touch quieter than it once did.
