Trail Overview
East Ten Ranch Road is a long, straight dirt track that leads from Highway 191 toward the Hot Well Dunes. As of March 25, 2025, the road has been recently maintained and is generally smooth and easy to drive, though drivers may encounter occasional humps and bumps. Travelers will pass through several cattle gates and may see cattle along the way. The route includes a few side trails and spurs branching off into State Land, where a permit is required for access. The surrounding landscape offers scenic views of the desert and nearby mountains. While the road provides opportunities for dispersed camping, it does not offer amenities such as water or trash disposal, and cell phone service is limited.
History
Around two million years ago, a shallow lake covered what is now southeastern Arizona. As the lake dried up, its sandy shores were shaped by wind into the dunes that define today's Hot Well Dunes Recreation Area. In the late 1920s, while drilling for oil in the San Simon Valley, workers unexpectedly struck geothermal water. The resulting artesian well still produces over 250 gallons per minute at a temperature of 106degF. Today, the Hot Well Dunes Recreation Area spans 2,000 acres of BLM-managed sand dunes, offering off-highway vehicle recreation, camping, and soaking in natural hot tubs fed by the artesian spring.
