Hot Well Dunes is a hot spring in the San Simeon Valley of Arizona, located on BLM land southeast of the town of Safford.
Hot Well Dunes are a series of artesian hot spring wells that are surrounded by 2000 acres of open BLM land. Camping is permitted at the site for a maximum stay of two weeks. There are two main soaking pools surrounded by a low metal fence and gate, cement benches; pit toilets are available on site. The two main pools overflow into a large rock-lined pool, the temperature is lukewarm. The site is surrounded by desert views. There is no trash pick-up at the site, and all trash must be removed by visitors to the hot springs. There are also more primitive soaking areas on-site surrounded by cattails that also provide habitat for wildlife and fish.
Hot Well Dunes are located on BLM land in a remote location the San Simon Valley, far away from any cities or towns.
