Hot Well Dunes is one of our most favorite places to go, and we usually go at least once a year. It is dry camping in the sand dunes. They have a few vault style bathrooms and two concrete hot tubs that you can use during the day. Some of the camping spots have Ramada like covers and concrete picnic tables. We bring our quads or side by side and explore the sand dunes. The fee was $3 per night per vehicle.
