How Crowded Is Chaco Culture National Historical Park in May?

May runs about 1.8× Chaco Culture National Historical Park's average month, which makes it a very busy month here — roughly 15% of the park's yearly visitors come in May.

In a typical May the park sees roughly 6,100 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Chaco Culture; January, the quietest, runs only about 0.2× the average — a 8-to-1 swing between high and low season.

On our Best Time to Visit score May rates 42/100 ("Poor"), versus the top-rated August at 74/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 76°F and an overnight low around 37°F, with about 0.6" 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 May instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 13.9 hours of daylight in May to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2024 drew 37,840 recreation visits, down 5.9% from 40,198 in 2023.

Across the past decade overall visitation has eased about 37%, so May may feel a touch quieter than it once did.
