Park headquarters, about a two-hour drive east of Portland, is adjacent to Oregon Route 206 between Wasco and Condon. The river, which here forms the boundary between Sherman County on the west and Gilliam County on the east, meanders for 16 miles (26 km) through the arid park.
The walls of the main canyon reach to 1,920 feet (590 m) above sea level within the park, which also includes four side canyons: Hay Creek, Esau, Rattlesnake, and Cottonwood. These and the main canyon are flanked by grassland, sagebrush shrub-steppe, river bottom, and cliffs composed mainly of basalts of the Columbia River Basalt Group.
