The condition of the road to the Telescope Peak trailhead varies depending on when the park service last ran a road grader through there. When we drove it several years ago, it was a bed of fist sized rocks past the kilns. We gave up, parked at Thorndike campground, and walked the rest of the way. Driving home, I noticed the car pulled to one side. Thinking that the alignment got knocked off, I took it to my mechanic. He pointed out that one tire had a chunk gouged out of it. At least, carry a full spare tire. Those donut spares don't cut it in Death Valley.
