Directions from Ridgecrest: Take 178 out to Inyokern and turn north on Brown Rd (at the railroad tracks). Follow Brown Rd north for approximately 5.5 miles and turn left on Neal Ranch Rd. Head west on Neal Ranch Rd towards Owens Peak for 8/10ths of a mile. Where the fence splits the road, a sign says “Keep Left”, you are at the south-eastern corner of the ranch. Continue on and look for the Robison Ranch sign at the gate. Turn right through the gate and park somewhere near the house.
