How Crowded Is Fort Stanwix National Monument in May?

May runs about 1.1× Fort Stanwix 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 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 (3.4×) and the January low (0.2×).

On our Best Time to Visit score May rates 67/100 ("Good"), versus the top-rated June at 74/100 — 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 69°F and an overnight low around 45°F, with about 4.5" 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 54% 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 14.5 hours of daylight in May to explore — between the 8.8-hour midwinter low and the 15.2-hour summer high.

Park-wide, 2025 drew 77,507 recreation visits, down 2.8% from 79,704 in 2024.

Across the past decade overall visitation has eased about 13.3%, so May may feel a touch quieter than it once did.
