Access
The Park Service’s Arizona Hot Springs Trail starts from parking “just off U.S. Highway 93 before mile post 4, south of Hoover Dam.” It runs 5 miles out and back, or 5.69 miles as a loop with the White Rock Canyon trail, over a “750 ft. elevation change” on a route the park rates strenuous. A “20 foot ladder to climb down” connects the springs to the White Rock Canyon trail; the Park Service says “Climb at your own risk.” Pets are allowed but “must be kept on a leash not to exceed six feet in length at all times.” The park asks visitors not to dam the springs — “Blocking water flow with sandbags or other items to create pools at the hot springs creates health risks” — and to follow leave-no-trace principles, packing out trash and human waste.
Trailhead: U.S. Highway 93 parking area before mile post 4, south of Hoover Dam
Winter: The heat closure runs May 15 to September 30; outside those dates the Park Service closes the trail temporarily whenever temperatures are forecast to reach 95 °F or higher at Willow Beach.

Worth knowing: Carried in the NCEI list as an unnamed “Hot Spring” on the Ringbolt Rapids quad; the Park Service publishes it as Arizona Hot Spring, the same feature older sources call Ringbolt.
