Arizona Hot Springs (aka Ringbolt Hot Springs) are located along the Colorado River just south of the Hoover Dam. Tucked away inside a colorful slot canyon, these hot springs offer a beautiful environment to enjoy a nice long soak. They can be accessed by boat via the Colorado River or by hiking a 3.2 mile trail down from the Arizona state highway 93. For our visit, we opted to take the trail.
Before setting out for this adventure, we were supplied by Fireside Provisions. They’re a camping meal delivery service based in San Francisco that ships pre-portioned meals straight to your door. We partnered with them earlier this year to develop their spring backpacking menu, and now we planned to take some of the meals we created with us for a little extended field testing.
What We Brought
Many people visit Arizona Hot Springs as a day hike, but we planned to camp there overnight. So we brought our standard backpacking setup (i.e. tent, pads, sleeping bags, etc) along with a couple of select “extras”.
Fireside Provisions Meals – Since we developed Fireside’s spring backpacking menu, we knew we were going to love them. So, instead of running around a grocery store the night before a big hike like crazy people, Fireside shipped all the ingredients straight to us.
SteriPen – This portable device uses ultraviolet light to sterilize water and kill off any malicious bacteria, viruses, and protozoa. We knew there wasn’t any potable water at the campsite, but with a SteriPen we had the entire Colorado River to drink from.
Enerplex Jumpr Stacks 6 – These portable, stackable batteries are perfect for charging our iPhones and GoPro. They have a built-in lightning and micro USB tether, so we don’t need to remember to bring our iPhone cables.
Enerplex Kickr Solar Panel – Super lightweight solar panel that we use to charge our Jumpr Stacks. We attached the panel to the back of our packs, so it could charge while we hike. We also set it out later in the day, to soak up some afternoon rays.
Merrell Moab Ventilator Boots – We brought these boots with us because the trail down is filled with sand, loose gravel, and boulders. And in a few section you have to scramble. The super grippy Vibram soles of these boots were perfect for the conditions.
Chacos Z/1 – We also brought these sandals with us because they are great for climbing around slippery wet surfaces. Whether we were swimming in the Colorado River or soaking in the hot springs, these are a great pair of outdoor sandals to have.
The trailhead parking lot is on the north side on State Route 93, about 3.5 miles south of the Pat Tillman Bridge. The weather was forecasted to be very hot, so we arrived early to get on the trail before the sun got too high. But even at 7am, the air was already pretty warm.
At the end of the parking lot, there are signs warning hikers about the heat. There have been so many fatalities here from sunstroke and dehydration that the trail is actually closed from June through August. Since the trail is relatively short, people tend to underestimate it. But it’s completely exposed nearly the whole way down.
Despite these ominous warnings, we did have one fortuitous sign. In the completely deserted parking lot, somebody had left a disposal cooler containing beer and rapidly melting ice. We helped ourselves to a couple “trail magic” beers to enjoy at the end of our hike, and started our descent down.
You can find a map for the Arizona Hot Springs hike here. The trail begins by taking you underneath the freeway and down a gravel filled wash. From here, there are two ways of getting to the hot springs. Hot Spring Canyon approaches the springs from behind and White Rock Canyon will allow to approach the springs from the river. We decided to go down White Rock Canyon and return back via Hot Spring Canyon.
Shortly after the wash, we quickly descended down into a high-walled canyon. The sun was still low enough on the horizon that this section remained almost entirely in the shade. We meandered down the loose gravel trail for about an hour and a half before we arrived at the banks of the Colorado River. Here we had to turn left, but while one might expect the trail to follow the river, it actually cuts inland in order to get up and over a ridge.
There are signs marking the way, even though the topography makes identifying the trail a little difficult. In a few areas, we had to scramble our way up and over a narrow rocky crack in a cliff. This was a little tricky with our overnight packs, but we managed to crawl our way up. At this point the sun was getting pretty high in the sky and we were starting to get the classic backpacker back sweat. Thankfully we were nearly there.
We descended into a gravel wash of Hot Spring Canyon and followed it down to the river. Here, we found a dozen kayaks, rafts, and canoes that had been pulled ashore on a semi-protected beach. A local tour group had just landed and was in the process of setting up camp nearby. There were also a few people who had arrived by power boat from downstream. With its flat open area and proximity to hot springs, this beach is a fairly popular camping destination. If you’re visiting on the weekends, be prepared to have a little company.
The weather forecast was calling for high winds during the evening, so we spent some time scouting out a good place to pitch our tent. There were plenty of spots inside the canyon, but the way the cliffs channeled the air, we felt it was actually more breezy there than by the river. So we decided on a secluded spot, tucked away in a thicket of brush. While there bushes didn’t offer much shade during the day, they did an excellent job of buffering the wind that night.
Despite the easy access from the river, this is backcountry camping. Which means no trash, no potable water, no designated campsite. The one exception are the two vault toilets setup just to the south of the beach. These were extremely clean and well-kept, as they are serviced by a park ranger about every week. When we arrived, the ranger was just leaving.
One sour note of the experience, was the amount of garbage we saw. Despite the signs urging people to Leave No Trace and Pack It In, Pack It Out, there were some areas that looked completely trashed. And not just an errant candy wrapper or empty water bottle, but entire campsites where the previous occupants had apparently thrown all their trash on the ground and just left. It truly breaks our hearts to see such carelessness and disrespect for the natural environment.
If you enjoy the outdoors, we highly recommend doing a little reading about Leave No Trace. The Pacific Crest Trail Association has a great write up that outlines best practices for camping in the backcountry.
The Hot Springs
After setting up camp, we threw on our bathing suits and made a trek up to the hot springs. As we hiked up the canyon, we found a trickle of warm water that was flowing down. The further up we went, the stronger the stream became and warmer the water got. In a few areas, we had to shimmy up a slippery rock chute as warm water rushed down it.
The trail dead ends at a 20 foot waterfall, but a ladder has been rigged up so you can access the hot springs located above. While securely fastened to the cliff, the rungs of the ladder were wet and slippery, making the final dismount at the top was a little tricky.
Here at the top, is where the first of the hot springs pools begin. Gravel filled sandbags have been stacked to create artificial pools to prevent the water from just rushing down the waterfall. The first pool is the coolest, but as you progress up the canyon they get progressively warmer. The top pool, which is closest to the source, runs at about 110 F degrees.
Near the hot springs there are also signs about Naegleria Fowleri – also known as the brain-eating amoeba – which can be found in thermal pools such as these. If present, the amoeba can travel up your nasal passage and cause a fatal infection. While such infections are extremely rare, with only 130 cases being reported to the CDC since 1962, it is still advised that visitors refrain from putting their head underwater. While these hot springs are beautiful, they are wild, and a certain degree of caution must be exercised when visiting them.
Since it was a warm day to begin with, we couldn’t handle the hotter pools at the top, so we spent most of our time hanging out in the lower pools. There we reclined in the clear water and listened to the sound of the waterfall echo down the canyon. While it was very exposed down by the beach, inside the canyon we could relax in the shade. Finally after a good long soak, we headed back to camp.
What We Ate
Spicy Sasquatch + Trail Mix: For lunch on the first day, we found a shaded spot along the Colorado River and made these spicy salmon pita pockets. This was a quick and easy trailside meal that didn’t require any cooking. Just combine the spices, mayo, and cashews into the pouch of salmon and filled up your pita. And unlike cans, the pouch of salmon could be folded up afterwards so not to take up space in our trash bag.
The Souk – For dinner, we made a pot of lemon chicken with couscous. After a long day, this meal really hit the spot for us. It was super quick to make (maybe 8 minutes from start to finish) and completely filling. The dehydrated spinach got us some often neglected veggies into our diet, while the chicken provided us with some much needed protein.
Big Bend Scramble – For breakfast on the second day, we were treated to a summer sausage and egg scramble. The dehydrated egg crystals are lightweight, but when they are combined with water they create delicious tasting scrambled eggs. We’ve always been wary of powdered eggs, but these were delicious.
The Hike Out
Having hiked in via White Rock Canyon, we decided to hike out via Hot Spring Canyon. This actually takes you through the hot springs, so if you’re going this way be prepared to get your feet wet. The water inside the pools isn’t much more than knee deep, but they can get pretty hot towards the top. We hiked through in our sandals and then switched back to our boots.
The hike back to the trailhead via Hot Spring Canyon was about a half mile shorter, but it was much steeper and far more exposed. The canyon walls aren’t as high as White Rock, so even the morning sun was peeking over the sides. Thankfully it wasn’t as hot as the first day.
The Arizona Hot Springs have got to be some of the most interesting springs we’ve visited so far on our trip. The hike to them was pretty incredible, the campground was right on the Colorado River, and the springs themselves were hidden away in an amazing slot canyon. If you’re in the area, we’d definitely suggest checking it out. But while this place is beautiful, it is a fragile environment, so enjoy responsibly.
