Pearrygin Lake State Park is a camping park with more than 1,200 acres in the Methow Valley of north central Washington. The park features expansive green lawns leading to 11,000 feet of waterfront on Pearrygin Lake. The lake offers swimming, fishing and boating. Old willows and ash provide shade on hot summer days. Hikers can also walk the Rex Derr trail, a 3.1-mile loop through the east campground and along the shrub steppe hillside above Pearrygin Lake. The park was originally purchased in 1959 from a local orchardist. In 1964, the park opened as a state park recreation area, including a small camp area.
