How Crowded Is Shiloh National Military Park in May?

May runs about 1.3× Shiloh National Military Park's average month, which makes it a busy month here — roughly 11% of the park's yearly visitors come in May.

In a typical May the park sees about 41,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

It is the single busiest month of the year at Shiloh; December, the quietest, runs only about 0.7× the average — a 2-to-1 swing between high and low season.

On our Best Time to Visit score May rates 45/100 ("Fair"), versus the top-rated September at 60/100 — 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 81°F and an overnight low around 59°F, with about 6.2" of precipitation.

That average of about 70°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 13.8 hours of daylight in May to explore — between the 9.6-hour midwinter low and the 14.4-hour summer high.

Park-wide, 2025 drew 346,955 recreation visits, down 10.2% from 386,152 in 2024.
