The hike is technically easy, except for the challenge of altitude, on a rutted jeep road (that is closed to traffic) the whole way. The drive to the hike is another matter, mostly asphalt on the way up, but then some miles of dirt road. Very moonscapey. Nice to have higher clearance, though we did it with a Volvo station wagon and saw a Honda civic succeed too. Also great hike among the ancient bristlecones at the forest right before the asphalt ends and dirt road starts, ~ 10,000'
