How Crowded Is Sand Creek Massacre National Historic Site in June?

June runs about 1.6× Sand Creek Massacre National Historic Site's average month, which makes it a very busy month here — roughly 14% of the park's yearly visitors come in June.

In a typical June the park sees about 790 recreation visits, based on National Park Service monthly counts from 2010 to 2025.

That makes June the 2nd-busiest of the park's twelve months, sitting between the July peak (1.6×) and the January low (0.2×).

On our Best Time to Visit score June rates 50/100 ("Fair"), versus the top-rated September at 58/100 — best overall balance of crowds, weather and daylight.

Typical June weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 87°F and an overnight low around 57°F, with about 2.4" of precipitation.

That average of about 72°F is a comfortable range for hiking and being outdoors all day.

June falls inside the park's busiest stretch: June, July and August together pull about 38% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.7 hours of daylight in June to explore — near the year-round maximum.

Park-wide, 2024 drew 6,401 recreation visits, up 9.3% from 5,855 in 2023.

Across the past decade overall visitation has eased about 11.4%, so June may feel a touch quieter than it once did.
