Environmental Features Physical Features Plant Life

Lake Chelan was carved by two competing glaciers -- the Chelan glacier and the continental ice sheet. Their back-and-forth movement created the broad lower lake and narrow upper lake. The park is set in rocky terrain, with forested areas along Twenty-five Mile Creek. The region receives an average annual rainfall of 11 inches, with 39 inches of average annual snowfall.

Twenty-Five Mile Creek State Park was a seasonal, Native American encampment site on the south shore of Lake Chelan. Native Americans came here by land to begin their uplake canoe trips and to fish and hunt at the site.

Constructed by Mr. Dave Davis, the park was operated for many years as a private resort. State Parks acquired it in 1972 and continued to operate it as a private resort under concession contracts with various tenants. Since 1988, park staff has operated the park.

The park has 46 tent spaces, 21 utility spaces (13 full hookup and eight with water and electricity), one dump station, two restrooms (one ADA) and six showers (two ADA).
