About 8,900 acres of desert peaks and washes in Imperial County, California, make up Picacho Peak Wilderness. Access is from Ogilby Road (S-24) between Interstate 8 and Highway 78, with Indian Pass Road running east toward Picacho State Recreation Area and the wilderness boundary. Travel is primitive; vehicles stay outside the wilderness line.
