Whitmore Hot Springs, Mammoth Lakes, CA: Updated Guide 2026
Before you scroll through every hot spring in California, let me save you time. I’m Vanessa, founder of CATRAVELTIMES, and after covering everything from roadside soaks to Hot Spring California, Whitmore Hot Springs is one stop I always highlight.
Located 9 miles south of Mammoth Lakes off US-395, this geothermal-fed, 25-meter outdoor lap pool operates under the Town of Mammoth Lakes from mid-June through early September. It’s lifeguarded, properly managed, and fed by genuine thermal water, a combination that sounds simple but is surprisingly hard to find anywhere along the Eastern Sierra.
What is Whitmore Hot Springs? Quick Detail
The Long Valley Caldera beneath Whitmore formed from a volcanic eruption 760,000 years ago one of the largest in North American history. Indigenous communities in the Owens Valley used these thermal waters for centuries.
The City of Los Angeles later developed the site through the Los Angeles Aqueduct system at Crowley Lake. The Town of Mammoth Lakes has operated the Whitmore Recreation Area for over 50 years. Located at 904 Benton Crossing Rd, Crowley Lake, CA 93546. Pool temperature: 80–90°F. Visitor rating: 4.4 stars on Google.
How To Find Whitmore Hot Springs? Direction & Map
From Mammoth Lakes, take US-395 south for approximately 9 miles. Turn left onto Benton Crossing Road look for the green church at the intersection, which locals use as the landmark. GPS: 37.6324, -118.8124. The access road is fully paved and any vehicle handles it without trouble.
Follow Benton Crossing Road about 1 mile past the ball fields to reach the Whitmore Recreation Area. Parking is free. The primitive, free alternative on Whitmore Tubs Road is 1.2 miles east on an unpaved road. Doable in a standard sedan in dry conditions. Muddy in rain. And the moment you clear that last stretch of road and see the pool deck against the Sierra backdrop, you’ll want to stop and take photos before you even change into your swimsuit.
Whitmore Hot Springs Photos Stunning & Scenic Views
I shot the pool at midday with all 3 mountain ranges in the frame, then again from the lawn at low sun. The contrast of blue water against the dry Eastern Sierra landscape is what keeps pulling me back to this shot.
The scenery alone makes the drive worth documenting, and once you see it in person, you’ll understand why the next thing to cover is everything else the facility offers.

What Facilities Does Whitmore Hot Springs Have?

On-site amenities include restrooms, hot showers ($3.00 per session), a shaded lawn, BBQ grills, vending machines, and complimentary Wi-Fi. Red Cross-certified lifeguards are on duty during every public swim session. For more California hot spring options with facilities, check the Hot springs directory at CATRAVELTIMES.
What Is the Whitmore Hot Springs Elevation?
Whitmore sits at 7,100 feet inside the Long Valley Caldera. At that elevation, sun exposure hits harder than it feels sunscreen is not optional, even on overcast days. If you’re arriving from sea level, give yourself an hour before getting into the warm water. Light-headedness and faster fatigue are common at 7,100 feet, especially in a heated pool. Drink at least 32 oz of water before your session.
Is There Camping at Whitmore Hot Springs?
There is no on-site camping inside the Whitmore Recreation Area. Bureau of Land Management (BLM) land along Benton Crossing Road and Owens River Road allows dispersed camping within a short drive. McGee Creek Campground and Convict Lake Campground are both within 10–15 miles with established sites. McGee Creek requires weekend reservations and operates April through October. If you want a fuller Eastern Sierra overnight experience, Murrieta Hot Springs also offers camping nearby.
Is Whitmore Hot Springs Open in Winter?
The Whitmore Pool is closed in winter full stop. Access roads in the region can become impassable from late fall through spring. If you’re in Mammoth Lakes during ski season and want to soak, Wild Willy’s Hot Springs and the Rock Tub remain accessible when roads allow. Check Mono County road conditions before heading out. The surrounding air can sit well below freezing while the natural spring water stays warm that contrast is jarring in the best way.
What’s the Water Temperature & Best Time to Visit Whitmore Hot Springs?
The main lap pool holds between 80–90°F warm enough to feel good, cool enough to actually swim laps without overheating. The children’s wading pool runs 2–4 degrees warmer. When I was there in late June, the air was cool in the morning and the pool felt like a perfect counterbalance.
| Season | Why Visit | Best Time | Water Temperature |
| Summer | Peak season, long daylight, open for daily public swim | Weekday afternoons | 85–90°F (main pool) |
| Winter | Pool is CLOSED — natural springs nearby when roads allow | N/A — pool closed | N/A |
| Spring | Early-season cool air, minimal crowds, valley is green | Late May–early June (lap swim only) | 80–85°F |

| Year-Round | Rock Tub Hot Springs nearby on BLM land, road-permitting | Anytime (check road conditions) | 100–104°F (Rock Tub) |
Early season is genuinely the sweet spot.Now that you know when to go, let me tell you what to actually bring because I’ve gotten this wrong before.
Things to Do at Whitmore Hot Springs
I spent most of my time in the water and on the lawn watching the mountains shift light. The Devils Postpile area was the one stop I wished I had more time for I rushed it. Don’t do that.
Inyo Craters
Located a short drive northwest of Mammoth Lakes, these 3 volcanic explosion craters are accessible via a 0.6-mile round-trip walk. Google rating: 4.6 stars. Free entry. The calderas hold small lakes and the views into them are unlike any other geology stop in the Eastern Sierra.

What Are People Saying About Whitmore Hot Springs?
Whitmore Hot Springs, with visitors consistently praising the mountain views, the clean facility, and the unusual pairing of lap pool function with geothermal water.
Families appreciate the lifeguards and the children’s wading pool. Lap swimmers love the open-air setting. My own takeaway: the 360-degree mountain view from the pool deck is the real draw, 3 ranges at once, no walls, just water and sky.
My Honest Talk on Whitmore Hot Springs
Whitmore Hot Springs is worth the drive if you know what it is going in: a well-maintained community pool fed by geothermal water, not a wild backcountry soak. Families, lap swimmers, and anyone who wants mountain views with their swim session will leave satisfied.
Visitors chasing an untreated thermal experience should head 1.2 miles east to the Rock Tub instead. What stayed with me after this visit was the specific feeling of swimming open laps at 7,100 feet with three mountain ranges filling every direction. There’s no gym in California that offers that. If you’re planning a broader Eastern Sierra loop, Whitmore pairs well with a stop at Bishop Hot Springs on the way south and if you’re still building your itinerary, browsing the full hot springs guide at CATRAVELTIMES is a good place to start.
