Coso Range Wilderness

Coso Ranfe Wilderness

Encompassing the northern section of the Coso Range, this Wilderness preserves an area of extensive erosion revealing outstanding displays of volcanic formations and numerous valleys and washes. From high points--primarily Joshua Flat in the east-central portion--you'll discover great views east into the Sierra Nevada and north into Owens Valley.

In addition to Joshua Flat, striking Vermillion Canyon runs west from near the middle of the area, offering an especially scenic reason to make the trek. Cactus Flat and McCloud Flat to the south were once active mining regions. You'll see large stands of Joshua trees mixed with low desert shrubs, annuals, cactuses, and creosote bushes. Old tracks lead from the east to Joshua Flat and from the west to Vermillion Canyon. There is ample room to wander without much chance of seeing another human. Carry plenty of water.
