'Columbia Hills Historical State Park is a 3,338-acre camping park with 7,500-feet of freshwater shoreline on the Columbia River. Horsethief Butte dominates the skyline. It stands over the lake like an ancient castle. The lake itself is about 90-acres in size and is actually an impoundment of the Columbia River. The lake was flooded into existence by the reservoir created by The Dalles Dam. Lupine and balsam root bloom in mid-April making spectacular fields of purple and gold. Rock climbing is possible in this park.'
