The campsite is cool, but crowded. You can get a permit to backpack a mile into the dunes (away from people's sight). It's a good hike into the dunes, but once you find a spot, it's incredible. Beware what time you go, it can be freezing and windy, so best to go probably in May. It's extremely secluded - you're fully surrounded by the dunes with the mountains in the background. Obviously good to be prepared with plenty of water and food cuz sand… Highly recommend doing this! One of my favorite and most memorable camping/backpacking trips, for sure.
The camping closer to devil's head is a bit crowded but once you head down towards the creek (went towards Jackson Creek down Jackson Creek Rd.), it's gorgeous with streams and giant rock walls with several secluded areas or large areas for big groups.
