You're going to be sore. That’s the first thing you need to accept before even looking at a map of the Ansel Adams Wilderness. Iva Bell Hot Springs isn't some roadside attraction where you hop out of a Subaru and dip your toes in. It’s a commitment. We’re talking about a roughly 13-mile hike just to get there, and honestly, if you aren't prepared for the elevation changes, those miles feel a lot longer.
Most people who make the trek are coming from Fish Valley or Red's Meadow near Mammoth Lakes. It’s a haul. But once you crest that final ridge and see the steam rising from the granite shelves overlooking the valley, the blisters suddenly stop throbbing. There’s something primal about soaking in naturally heated mineral water while staring at the jagged peaks of the Sierra Nevada. It’s quiet. It’s remote. It’s exactly what the High Sierra should be.
Getting to Iva Bell Hot Springs Without Losing Your Mind
Planning is everything here. You can't just show up. Since the springs are located within the John Muir Wilderness and the Ansel Adams Wilderness boundaries, you need a wilderness permit. If you’re starting from the most common trailhead at Red’s Meadow, you’re looking for the Fish Creek Trail.
The hike is a bit of a rollercoaster. You’ll drop down into the valley, which feels great at first, but then you realize you have to climb all that way back out on the return trip. The trail winds through charred forests—remnants of the 1992 Rainbow Fire—and lush meadows that look like something out of a postcard.
- Distance: Approximately 26 miles round-trip.
- Elevation: Expect a net loss/gain of about 3,000 feet depending on your specific route.
- The path can get dusty. Really dusty. In late summer, the pumice soil turns into a fine powder that gets into every gear crevice you own.
One thing people often overlook is the river crossing. Depending on the snowpack from the previous winter, crossing Fish Creek can range from a simple rock hop to a dangerous, waist-deep wade. If it’s a heavy snow year and you’re going in June, be extremely careful. Most seasoned backpackers wait until July or August when the water levels drop and the mosquito swarms start to thin out, though "thin out" is a relative term in the Sierras.
What Makes the Pools at Iva Bell So Special?
Unlike some hot springs that are just a lukewarm puddle in the mud, Iva Bell Hot Springs consists of several distinct pools tiered down a hillside. The water temperature varies. The higher you go up the hill, the hotter it gets.

The "Main Pool" is usually the favorite. It’s perched on a granite ledge that gives you a panoramic view of the valley below. Imagine sitting in 102-degree water while the sun sets over the Minarets. It’s unreal. The pools are mostly sand-bottomed or granite, so you aren't dealing with that slimy, sulfurous muck found at lower-elevation springs.
There are about five or six usable pools. Some are big enough for four people; others are strictly "solo soak" territory. Because the site is so remote, you’ll often find you have the place to yourself, or perhaps you'll share it with a few other weary hikers who are just as exhausted as you are. There’s a silent pact among Iva Bell visitors: keep it mellow.
The Logistics of Camping Near the Springs
You aren't allowed to camp right on top of the springs. This is a crucial rule enforced by the U.S. Forest Service to protect the fragile ecosystem. There are several well-established campsites located about a quarter-mile away in the woods and near the creek.
Look for sites that already have a fire ring (though check fire restrictions first, as they are common in California). You want to be close enough to the water to hear the creek but far enough from the springs to respect the "no camping" zone.
Bear canisters are mandatory. This is high-density black bear country. Don't be the person who loses their entire food supply on night one because they thought a "bear bag" hang was sufficient. Use an approved hard-sided canister and keep it at least 100 feet from your tent.

Common Misconceptions and Safety Realities
A lot of folks think that because it's a "hot spring," it's a spa experience. It isn't. This is rugged backcountry. There are no toilets, no trash cans, and no cell service. If you get hurt at Iva Bell Hot Springs, help is a long way off.
- The Water Quality: While the water is flowing and generally clean, never submerge your head. Thermophilic organisms, including the rare but deadly Naegleria fowleri (brain-eating amoeba), can technically exist in warm natural waters. It’s a "better safe than sorry" situation.
- The Heat: Don't soak for three hours straight without drinking water. Dehydration hits twice as hard at 8,000 feet when you're simmering in a natural hot tub.
- The Bugs: Mentioning mosquitoes again because they are legendary here. Bring a head net. You might look ridiculous, but you’ll be the only one not vibrating with frustration.
The Environmental Impact
Iva Bell has seen an uptick in popularity over the last few years thanks to social media. With that comes the "Leave No Trace" talk. It’s boring but vital. The mineral deposits around the springs are fragile. Walking on the delicate "travertine-like" edges can break off chunks that took decades to form.
Avoid using soap in the pools. Even "biodegradable" soap isn't meant for hot springs; it wreaks havoc on the water chemistry and the microorganisms that live there. If you need to wash, do it 200 feet away from any water source using a collapsible bucket.
Why July and September are the Sweet Spots
If you go in June, you're fighting snow on the passes and high water in the creeks. If you go in August, it can be brutally hot during the day. September is the "Golden Era" for Iva Bell Hot Springs. The nights are crisp, the bugs are dead, and the water feels even better when there’s a chill in the air.
Just keep an eye on the weather. Early season snowstorms aren't unheard of in the High Sierra. Getting caught 13 miles from your car in a whiteout is a quick way to turn a relaxing soak into a survival situation.

Practical Steps for Your Trip
Before you pack your bag, do these things. First, check the Inyo National Forest website for permit availability. They use a lottery system for peak dates, so plan months in advance.
Next, verify the trail conditions. The Pacific Crest Trail (PCT) community often posts updates on water levels and downed trees in this area, so checking PCT forums can give you real-time intel that official sites might miss.
Pack a light pair of sandals or Crocs. You do not want to be putting your heavy hiking boots back on every time you hop out of a pool to walk back to camp. Your feet will thank you for the airflow.
Finally, bring a physical map. GPS is great until your battery dies or the cold kills your phone. The Tom Harrison "Ansel Adams Wilderness" map is the gold standard for this region.
Actionable Insights for the Trail
- Permit Timing: Log onto Recreation.gov exactly six months in advance at 7:00 AM PST for the best chance at a trailhead permit.
- Water Treatment: Filter all water from Fish Creek. Do not drink the hot spring water itself; the mineral content can act as a natural laxative.
- Weight Management: Keep your pack under 30 pounds if possible. The climb out of Fish Valley is relentless, and every ounce of "luxury" gear will feel like a brick by mile 20.
- Soak Etiquette: If you arrive and the pools are full, wait your turn or ask to share. Most people are friendly, but space is limited.
- Health Check: If you have any open cuts or scrapes, stay out of the pools. It protects you from infection and keeps the water clean for everyone else.
Iva Bell Hot Springs remains one of the last "authentic" backcountry experiences in California. It demands physical effort, careful planning, and a deep respect for the land. If you put in the work, you get to experience one of the most spectacular natural baths on the planet. Just remember to pack out your trash—every single bit of it.
