Hot Spring
Arizona Hot Springs (also called Ringbolt Hot Springs) reaches only 86°F but offers spectacular Colorado River canyon scenery within Lake Mead National Recreation Area. The modest temperature elevation of 11.6 degrees above ambient occurs in one of America's most iconic geothermal-recreation combinations.
This thermal spring sits at 760 feet elevation along the Colorado River corridor, requiring a challenging hike of nearly two miles (approximately 9,900 feet) from Hoover Dam-Kingman Highway. The dramatic canyon walls frame the spring's setting where desert vegetation clings to steep slopes. The river corridor provides water and landscape contrast to surrounding aridity.
Arizona Hot Springs represents geothermal activity along the Colorado River corridor within the broader Lake Mead geothermal system. The modest temperature indicates lower geothermal gradient compared to other Arizona springs. The location's significance expanded dramatically after Hoover Dam construction in 1936 created Lake Mead.
The spring sits on National Park Service lands within Lake Mead National Recreation Area offering open public access. The two-mile hiking approach from Hoover Dam-Kingman Highway requires adequate water, sturdy footwear, and sun protection. Summer temperatures in the canyon can exceed 115°F. The area sees moderate day-use visitation.
