Diamond Craters Outstanding Natural Area
Geologic Sightseeing > Diamond Craters Outstanding Natural Area (OR) 
55 miles south of Burns, Oregon.
Diamond Craters contains hundreds of pristine volcanic features. Geologists maintain that the 17,000-acre area has some of the best and most diverse examples of basaltic volcanism in the United States. The 64-mile Diamond Loop Back Country Byway meanders through a sagebrush-covered landscape, which is punctuated by buttes and rimrock above broad, water-filled valleys. Wild horses, including the famous Kiger mustangs (thought to be one of the purest herds of Spanish mustangs existing in the wild today), mule deer, pronghorn antelope, hawks, and eagles are among the many species of wildlife that can be seen.
From Burns, take State Highway 205 south approximately 41 miles to the Diamond turn-off. Travel east 7 miles to Diamond Craters junction, turn left on Lava Beds Road, and follow signs 2 miles north to Diamond Craters.
