How Crowded Is Knife River Indian Villages National Historic Site in August?

August runs about 2.4× Knife River Indian Villages National Historic Site's average month, which makes it a very busy month here — roughly 20% of the park's yearly visitors come in August.

In a typical August the park sees roughly 2,000 recreation visits, based on National Park Service monthly counts from 1981 to 2025.

That makes August the 2nd-busiest of the park's twelve months, sitting between the July peak (2.9×) and the January low (0.1×).

On our Best Time to Visit score August rates 64/100 ("Good"), versus the top-rated June at 67/100 — best overall balance of crowds, weather and daylight.

Typical August weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 80°F and an overnight low around 57°F.

That average of about 68°F is a comfortable range for hiking and being outdoors all day.

August falls inside the park's busiest stretch: June, July and August together pull about 61% of the year's visitors, so a visit this month means sharing the park with the peak-season crowd.

You'll have about 14.1 hours of daylight in August to explore — between the 8.3-hour midwinter low and the 15.7-hour summer high.

Park-wide, 2025 drew 9,048 recreation visits, down 16.7% from 10,867 in 2024.

Across the past decade overall visitation has eased about 7.2%, so August may feel a touch quieter than it once did.
