We got there around 9am on the Friday before Labor Day and it was already packed. We found two spots available and chose #37. Beautiful views throughout the campground (not from our site) we hiked, the kids played in two different creeks, and we enjoyed having space between ourselves and other campers. Incredible stars, and quick access to the trailhead (which was packed all weekend) Since it was a holiday weekend, cars were constantly driving up the road in search of a site. We even had one night where a group set up camp in a non-site area right beside us and drunkenly sang Queen songs until 4 am but thankfully the ranger kicked them out a few hours later. When we left on Sunday afternoon there were many spots available. Definitely need a vehicle with high clearance since the road is very rocky. There are few places to turn around and if you come on a busier weekend, you may want to grab the first spot you see.
