Arizona Hot Spring -- Hot Spring Canyon Route

Due to extreme temperatures, this area is closed during summer. Link to details (PDF).


In addition to the Regular Route (White Rock Canyon) to Arizona Hot Spring, two other good routes lead down Hot Spring Canyon to the hot spring. The first, the Washes Route, is longer (2.8 miles) and easier, but requires downclimbing several pour-overs, including one that is 30-ft high and 4th-class. The second, the Mountains Route, is shorter (2.2 miles) and steeper, but avoids the climbing.

Either way, this volcanic area is geologically interesting, and both routes lead to thigh-deep hot pools in the bottom of a deep, narrow slot canyon near the Colorado River. Using a tall ladder beyond the hot springs, hikers can continue to the Colorado River and restrooms. Arizona Hot Springs is a place to sit, relax in the warm water, and meet interesting people.

Departing the trailhead (view SW)

Hiking down the steep Mountains Route or hiking down the White Rock Canyon Route and hiking back up the Wash Route makes a nice loop. There are several nice places to camp down by the river where toilet facilities are available.

Arizona Hot Spring is sometimes called Ringbolt Hot Springs, a reference to Ringbolt Rapids that now lie submerged in the Colorado River, just upstream from the mouth of Hot Spring Canyon. There is no longer any evidence of a rapid.

Watch Out

Because of extreme summer temperatures, more and more hikers were being rescued from this area in the early 2010s, and some even died. The extreme temperatures also put the lives of rescue personnel at risk, and therefore, the National Park Service closes this area during summer.

Other than the standard warnings about hiking in the desert, ...the washes route is a fairly easy hike punctuated by three exciting pour-overs to downclimb. Most people probably would prefer a rope for the first, 30-ft downclimb. At the hot springs, be careful walking on wet rocks after you've picked up sand on the bottom of your shoes.

Because of past law suits, the Park Service posts signs warning about Naegleria fowleri, a bacterium present in warm waters like home hot tubs and hot springs. While this bacterium may be present here, it is not the extreme hazard it is made out to be by hysterical parties. It is, however, a good idea to keep your nose dry while in the hot pools.

While hiking, please respect the land and the other people out there, and try to Leave No Trace of your passage. Also, this is a moderately long hike in a remote area, so be sure to bring the 10 Essentials. Be sure that you are physically fit and that you choose routes of the appropriate difficulty for your skills and endurance.

In recent years, water at the hot spring has become contaminated with Escherichia coli (E. coli), human fecal bacteria, because people are walking upstream from the hot pools and pooping. Don't do this; it is gross and it will wash down into the hot pools. Use the vault toilets at the beach.

Getting to the Trailhead

This hike is located along Highway 93, south of the Hoover Dam in Lake Mead National Recreation Area, about 45 minutes southeast of Las Vegas.

From town, drive out to Lake Mead NRA, continue over the bridge into Arizona, and drive 4 miles down to the White Rock Canyon Trailhead. Park here; this is the trailhead.

The Hike

From the trailhead at the far end of the parking area by the information kiosk (Table 1, Wpt. 01), the trail runs down and right into White Rock Wash, and then down under the Highway 93 bridges. Just past the southbound bridge, trailhead signs (Wpt. 02) introduce the route.

The signs give distances and directions to destinations, warn of flash floods, admonish hikers to "pack it in; pack it out," and warn of Naegleria fowleri (see above): Warning. Do not allow water to enter your nose. Naegleria fowleri, an amoeba common to thermal pools [including backyard hot tubs] may enter [your nose] causing a rare [brain] infection and death. While this is true, have you ever heard of someone dying from a brain infection they got from their hot tub? Pay attention, but keep your fears in perspective.

Hot Spring Canyon
Trail and old road to Hot Spring Canyon (view SW)

From the signs, the White Rock Canyon Route and the Hot Spring Canyon routes continue down White Rock Wash. The White Rock Canyon Route runs straight down White Rock Wash to the Colorado River, and hikers can look west, out across the close mountains, into the Black Canyon Wilderness Area in Nevada on the other side of the Colorado River. Turning around, the high mountains beyond the highway are Wilson Ridge, an ancient granite ridge that is the core of the volcano that produced the surrounding landscape, and which is protected for recreation and nature in the Mount Wilson Wilderness Area.

At about 0.5 miles out, hikers can see a trail climbing the left bank (Wpt. 03) and exiting the wash to the southwest. Then, at about 0.6 miles out, adjacent to a "climb to safety" flash-flood warning sign, an old road can be seen exiting the wash to the left. Either of these routes can be used to exit White Rock Wash and hike over to Hot Spring Canyon.

Out of the wash, the trail runs up over a low ridge, drops across a wash, climbs over a second low ridge, and drops into the next wash where it merges with the old road. Alternatively, hikers can follow the old road as it contours across the hillsides.

Shortly after merging with the old road, the trail leaves the old road and runs up across a hillside onto a ridgeline (Wpt. 20), which is the highpoint along the Washes Route.

At this point (Wpt. 20), the Washes Route and Mountains Route diverge. The Mountains Route turns right and heads west into the mountains, while the Washes Route turns left and heads south down into the canyon.

From the highpoint (Wpt. 20), the Washes Route turns left and heads south. The trail runs across slickrock hillsides for 0.27 miles, eventually dropping into a sandy wash (Wpt. 19). The route then follows this wash downhill all the way to the hot spring and the Colorado River beyond.

Shortly after dropping into the wash, the wash merges with another wash coming down from the east, and both run into a V-shaped gully between two low ridges (Wpt. 18). The canyon suddenly narrows and drops into a slot that isn't obvious from above.

The canyon narrows and deepens, and in about 10 minutes hikers round a corner to the top of a 25-ft pour-over with no apparent way down (Wpt. 17). The route passes this obstacle along the north wall (right on the way down). Climb up about 10 feet to a ledge, then follow the ledge west around the corner past the pour-over. The route then descends the steep, 30-ft-high, 4th-class rock face back into the wash. The climbing is easy and the handholds are big, but if you fall you die -- so be careful.

Below the big pour-over, there are two more pour-overs before getting out of the narrows. The first is about 5 minutes below the big pour-over (Wpt. 16). This one requires about 20-25 ft of 3rd-class scrambling down a smooth slot adjacent to the main pour-over. Fortunately, the top is easy, so hikers are close to the ground before it gets more challenging.

The second pour-over is a few minutes farther down. This one requires about 15-20 ft of 3rd-class face climbing on big holds adjacent to the pour-over. From the big pour-over, it takes less than 15 minutes to pass the narrows.

Below the narrows (Wpt. 15), the route continues down the canyon for about 15 minutes to a confluence with another major wash (Wpt. 14). Stop for a minute and look around the area so you will remember the way out. Small red and white arrows painted on the rocks will help, but people get confused here.

From the confluence, the route continues down the wash. Watch for the bottom end of the Mountains Route (Wpt. 23) in case you want to go back that way.

About 40 minutes below the confluence, the route enters another set of narrows (Wpt. 13), the top of which is marked by a cottonwood tree and a mesquite thicket. The wash drops into a slot (10-ft easy scramble down) where the bottom of the slot has a small pool of hot water. The hot springs and hot pools are just around the corner (Wpt 12).

From the hot springs, either return to the trailhead by hiking out the Mountain Route or the Washes Routes, or consider making a big loop and hiking out using the White Rock Canyon route, which requires no serious climbing and is not steep, but it is longer.
