Overview

This is the desert’s wild spa day—if you earn it. The Arizona Hot Springs (aka Ringbolt) sits in a volcanic canyon that drops to the Colorado River, then funnels you up a narrow slot to natural hot pools. The shortest out‑and‑back is about 4.9 miles total with roughly 900 feet of gain; a popular loop using White Rock Canyon runs about 5.9 miles with around 750–1,000 feet of total elevation change. Expect hands‑on scrambling and a 20‑foot ladder near the springs.

Route Options

  • Shortest route: Arizona Hot Spring Canyon out‑and‑back (≈4.9 miles total). It heads up the slot to the springs with wet, slick sections and the ladder.
  • Loop option: Combine White Rock Canyon to the river, walk downstream past Ringbolt Rock to Hot Spring Canyon, then climb the slot and ladder to the pools before returning. Adds effort and variety.

A notable landmark is Ringbolt Rock at the river mouth—an echo of the pre‑dam river‑running days—before you turn into the slot for the springs.

The Springs

Water flows naturally at roughly 30–50 gallons per minute and is very hot—generally about 111–120°F. Enter slowly and mind your footing. Do not alter the springs or build/dam pools; it’s not allowed and creates health risks. Pit toilets sit about 200 yards downstream along the Colorado River; pack out everything else.

What You’ll See

The canyons here are strikingly volcanic—dark tuffs and ash with occasional pale granite boulders. Watch for hardy desert plants like indigo bush, ground cherry, rabbit brush, Mormon tea, globemallow, cheesebush, desert fir, and rock nettle. The slot narrows and short scrambles keep the route engaging.

Difficulty, Hazards, and Who It’s For

This is a strenuous hike with steep scrambling, a wet ladder, and a stiff climb out at the end. Summer heat is dangerous; flash floods are possible in stormy weather. You will get wet near the springs. Leashed pets are generally allowed in the area, but the ladder and narrows make this route impractical for many dogs.

Best Time to Hike

Go in the cool season—October through April is the sweet spot, with shoulder days in September and May if temperatures are reasonable. Start early for shade in the canyons and to beat crowds. Avoid storm forecasts and midday heat.

Tips and Tricks

  • Ladder: One person at a time; rungs can be slick. Light gloves help.
  • Footwear: Grippy shoes for wet rock; expect to get soaked in the slot.
  • Water: Carry plenty and bring electrolytes—this desert works you harder than you think.
  • Etiquette: Leave the springs as you found them; do not modify pools. Use the downstream toilets when possible and pack out all waste.

If you want similar canyon vibes without the hot water and ladder, the neighboring White Rock Canyon segment alone offers big‑wall scenery and easier logistics.

Pros

  • Historic Ringbolt Rock at the river mouth adds a cool sense of place
  • Pit toilets located about 200 yards downstream from the springs
  • Rare combo of river walk, slot, ladder, and natural hot water

Cons

  • Wet 20‑foot ladder and slick narrows—expect to get soaked
  • Brutal heat outside cool months and real flash‑flood risk
  • Steep climb out makes the finish feel tougher than the start

Parking

Park at White Rock Canyon Trailhead on the Arizona side of Hoover Dam, about 4 miles south, then follow signs toward White Rock Canyon or Arizona Hot Spring Canyon.

Caution

Very hot water, wet and slick ladder, flash‑flood danger in storms, extreme desert heat; do not alter pools and pack out waste. Watch for rattlesnakes.
