How Crowded Is Timpanogos Cave National Monument in May?

May runs about 1.1× Timpanogos Cave National Monument's average month, which makes it an average month here — roughly 9% of the park's yearly visitors come in May.

In a typical May the park sees about 10,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes May the 5th-busiest of the park's twelve months, sitting between the July peak (2.9×) and the January low (0×).

On our Best Time to Visit score May rates 62/100 ("Good"), versus the top-rated September at 63/100 — best overall balance of crowds, weather and daylight.

Typical May weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 66°F and an overnight low around 44°F, with about 3.4" of precipitation.

That average of about 55°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 64% 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 14.2 hours of daylight in May to explore — between the 9.1-hour midwinter low and the 14.9-hour summer high.

Park-wide, 2025 drew 92,031 recreation visits, down 19.3% from 114,034 in 2024.

Across the past decade overall visitation has risen about 18.8%, so a May visit is likely to feel busier than it did a few years ago.
