Sound like a day at the beach? The sands at the Hot Well Dunes Recreation Area were a beach surrounding a lake approximately two million years ago. What remains today is one of the most unique recreation spots in Arizona. Hot Well Dunes provides the opportunity to ride 2,000 acres of sand dunes, set up a camp, and then soak in relaxing hot tubs, all in the same location. However, please be considerate of your neighbors who may not be here to participate in the same activity as you. This is the only way this area will continue to be available to have fun in the sand, sun, and water.
