Teensy Thorndike is one of four free first-come, first-served campgrounds in the mountains. With only six sites at an elevation of 7400ft, you'll likely find tranquility galore but need a high-clearance and possible 4WD to get up here – check road conditions beforehand. There's no water but sites have fire pits and tables and there are vault toilets.
