Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Extremely hot geothermal springs (~170–180°F) emerging along the Gila River bank inside Gila Box Riparian National Conservation Area. Not a classic soak—water is scalding at the source—but a rare undeveloped geothermal feature reached via BLM backcountry routes and river access, with riparian birding and desert canyon scenery.
