The park features the 3.1-mile Rex Derr trail, a multi-seasonal trail that begins at the east boat launch, traverses a hillside up through the shrub-steppe environment, skirts the old Graves Homestead and winds its way back through the east campground.
Located four miles northeast of Winthrop, Wash., in north central Washington in Okanogan County.
