Do NOT go in from the Warm Springs Camp! We rented a jeep from Farabee Jeep Rental place by Furnace Creek. The road gets EXTREMELY treturous and unless if you are an experienced 4x4 driver and have your head screwed on straight, I would not recommend this route. If you are a jack*$ driver, you WILL get stuck in Mengel Pass area!!! The roads for Barker Ranch are not marked well (probably on purpose). If you must see Barker ranch, then I would recommend you going in from Ballarat Ghost Town road in and back out the same way. It was eerie going there.
