How Crowded Is Rainbow Bridge National Monument in May?

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

In a typical May the park sees roughly 7,200 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 75/100 ("Excellent"), versus the top-rated April at 76/100 — 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 82°F and an overnight low around 56°F, with about 0.4" of precipitation.

That average of about 69°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 62% 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 hours of daylight in May to explore — between the 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2025 drew 11,404 recreation visits, up 246.6% from 3,290 in 2021.

Across the past decade overall visitation has eased about 61.9%, so May may feel a touch quieter than it once did.
