Deep in the high desert of eastern Oregon lies a landscape so dramatic it’s often called the “Grand Canyon of Oregon.” Lake Owyhee State Park is a remote oasis set against a backdrop of towering, multi-colored volcanic rock formations. This hidden gem offers solitude, breathtaking geology, and a 53-mile-long reservoir that winds through the canyon like a blue ribbon.
Dramatic Geology
Marvel at the jagged, colorful volcanic tuff and rhyolite formations that rise steeply from the water’s edge.
Desert Stargazing
Far from city lights, the night skies here are pristine, offering some of the best stargazing in the Pacific Northwest.
Oasis Camping
Camp in a green oasis of trees and irrigated lawns that contrasts starkly with the surrounding arid desert hills.
Adventure in the Badlands
The Owyhee Reservoir is a boater’s dream, stretching for miles with countless hidden coves and side canyons to explore. Wildlife is abundant here; keep an eye out for golden eagles soaring overhead, pronghorn antelope on the hillsides, and bighorn sheep scaling the cliffs. The rugged terrain is a paradise for rockhounds, who scour the area for jaspers, thundereggs, and petrified wood.
Remote Wilderness
This is true wilderness. There is no cell service, and the nearest gas station is over 30 miles away. Come prepared with supplies and a full tank.
Camping and Cabins
The McCormick and Indian Creek campgrounds provide a comfortable base for your desert adventure. Modern cabins are also available for those seeking a roof over their heads. Evenings are magical as the setting sun ignites the red rock walls, followed by a silence so profound you can hear the wind whisper through the sagebrush.
