How Crowded Is Walnut Canyon National Monument in August?

August runs about 0.9× Walnut Canyon National Monument's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in August.

In a typical August the park sees about 13,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes August the 9th-busiest of the park's twelve months, sitting between the April peak (1.5×) and the January low (0.4×).

On our Best Time to Visit score August rates 70/100 ("Good") — the single best-rated month at Walnut Canyon, balancing crowds against weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 82°F and an overnight low around 55°F, with about 3.4" of precipitation.

That average of about 69°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 27% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 13.3 hours of daylight in August to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2024 drew 187,205 recreation visits, up 22.7% from 152,548 in 2023.

Across the past decade overall visitation has risen about 14.2%, so a August visit is likely to feel busier than it did a few years ago.
