Columbia Hills Historical State Park is 2 mi. e. of the US 197 jct. on SR 14, at milepost 85. It encompasses multiple ancient basalt lava flows shaped by Ice Age floods. Horsethief Lake and the Columbia River offer opportunities for swimming, boating and windsurfing. The lake provides excellent conditions for beginning windsurfers. Horsethief Butte is a popular rock climbing area.
The park is renowned for its rock art, created by Native Americans between 200 and upwards of 3,000 years ago—perhaps the greatest concentration in the Pacific Northwest. An interpretive display overlooks rock art relocated from Petroglyph Canyon, which was flooded by the reservoir behind The Dalles Dam in 1956.
Free, guided 90-minute tours of rock art sites are offered Fri.-Sat. at 10, Apr.-Oct.; reservations are required. Note: The trail is not ADA accessible.
Recreational activities are permitted. Camping is permitted. Picnicking is permitted.
