Lucky Peak State Park

Lucky Peak State Park is a public recreation area covering a total of 240 acres on and near Lucky Peak Lake approximately ten miles east of Boise in Ada County, Idaho. The state park has three units: Discovery Park off State Highway 21, a roadside park for picnicking and fishing in the Boise River; Sandy Point at the base of the Lucky Peak Dam, with sandy beach and calm waters for wading and swimming; and the Spring Shores unit with boat ramps and marina at the northern end of the lake. The park was created in 1956 by agreement with the United States Army Corps of Engineers, following completion of the Lucky Peak Dam. The park is also home to the Lucky Peak Dam Zeolite Occurrence.
