Columbia Hills State Park is a 3,338 acre camping park with 7,500 feet of shoreline on the Columbia River. The park includes the Horsethief Lake and Dalles Mountain Ranch areas. The lake is 90 acres in size and came into existence from the reservoir created by The Dalles Dam. Above the lake is Horsethief Butte and if you look up at the cliffs from the river you can see the stratigraphy highlighted by benches rising up the cliffs. The park also features some of the oldest Native American petroglyphs and pictographs in the Northwest. Fees are required for camping and boating.
