Roper Lake State Park Hot Spring

Roper Lake State Park in Safford, Arizona, features a naturally warm artesian well that feeds a small concrete soaking tub in the desert park on the edge of the Graham Mountain foothills, where bicarbonate-rich water at around 38°C provides year-round warm bathing in a convenient and family-friendly state park setting. The hot spring is part of the broader Safford-Lordsburg Geothermal Area, one of the most geothermally active regions in Arizona's Gila River valley, where the tectonic intersection of the Basin and Range and the Colorado Plateau produces numerous warm springs. The surrounding Sonoran Desert landscape, with the spectacular 3,000-metre Mount Graham rising immediately to the west, creates a dramatic backdrop for this accessible desert spa experience.
