7 Hidden Hot Springs In California That Aren’t Crowded

California hides some amazing natural hot springs away from the tourist crowds. These mineral-rich waters offer healing properties and spectacular views without the noisy chatter of packed resorts. I’ve spent years exploring these secluded spots, soaking in their therapeutic warmth while enjoying California’s diverse landscapes in blissful solitude.

1. Travertine Hot Springs: Nature’s Limestone Masterpiece

Tucked away near Bridgeport, these stunning pools sit beneath the dramatic Sierra Nevada mountains. The mineral-rich water flows over naturally formed travertine steps, creating several soaking pools of varying temperatures.

What makes Travertine special is how the pools have formed over centuries, with calcium deposits creating smooth, comfortable surfaces perfect for relaxing. While locals know about this gem, its location off Highway 395 keeps it relatively uncrowded, especially on weekdays.

I recommend visiting at sunrise when steam rises mystically from the pools and the mountains glow pink. Bring plenty of water and pack out everything you bring in – keeping these springs pristine ensures they’ll remain beautiful for years to come.

2. Wilbur Hot Springs: Historic Healing Waters

Hidden in a 1,800-acre nature preserve in Colusa County, Wilbur Hot Springs has flowed continuously for thousands of years. Native Americans considered these waters sacred long before the first bathhouse was built here in the 1860s.

Though technically a resort, Wilbur maintains a peaceful, uncrowded atmosphere thanks to its limited capacity and remote location. The historic Japanese-style flume system channels mineral water of varying temperatures through different soaking areas.

During my last visit, I spotted deer drinking from the nearby creek at dusk while soaking in the 98-degree pool. The springs operate as a digital detox zone – no cell service means genuine disconnection from the outside world, creating the perfect environment for true relaxation.

3. Sykes Hot Springs: The Backpacker’s Reward

If you’re willing to work for your soak, Sykes Hot Springs offers the ultimate wilderness hot spring experience. Located deep in the Ventana Wilderness of Big Sur, reaching these springs requires a challenging 10-mile hike each way.

The journey keeps crowds minimal, especially if you visit midweek in spring or fall. After crossing the Big Sur River multiple times, you’ll discover several small pools nestled alongside the river, perfectly positioned for stargazing.

However, before planning your trip, check current trail conditions – the area was damaged in wildfires and floods in recent years. I once hiked through a light rain to reach these springs, making the eventual hot soak even more rewarding. Pack light but bring camping gear if you plan to stay overnight.

4. Mercey Hot Springs: Desert Oasis Hideaway

Though it’s just a two-hour drive from San Francisco, Mercey Hot Springs feels worlds away from civilization. This historic healing center sits in the arid foothills of the Diablo Range, offering a unique desert hot spring experience.

Unlike flashier resorts, Mercey maintains its rustic charm with vintage clawfoot tubs for private soaking and a small communal pool. The springs contain a rich mineral profile including lithium, which some believe promotes relaxation and mental clarity.

My favorite time to visit is during winter weekdays when you might have the entire place to yourself. Bird watchers will appreciate the nearby Panoche Hills, home to golden eagles and prairie falcons. The night sky here, far from city lights, reveals stars in breathtaking clarity.

5. Deep Creek Hot Springs: Desert Canyon Escape

Nestled in the San Bernardino National Forest, Deep Creek Hot Springs offers several natural pools of varying temperatures alongside a cool rushing creek. The contrast between hot mineral water and the refreshing creek creates the perfect natural spa experience.

Though somewhat challenging to reach, the springs remain less crowded on weekdays and during cooler months. Two trails lead to these springs – a steep 2-mile route from Bowen Ranch or a longer but gentler 6-mile path along the Pacific Crest Trail.

During my February visit, I had the warmest pool almost entirely to myself while watching bighorn sheep navigate the canyon walls. Fair warning: some visitors embrace the clothing-optional tradition here. Pack plenty of water and sturdy shoes for the hike, and consider bringing a trash bag to help keep this natural treasure clean.

6. Harbin Hot Springs: Phoenix Rising From the Ashes

After being devastated by the Valley Fire in 2015, this beloved retreat center in Middletown has gradually reopened with rebuilt facilities and a renewed spirit. Though more developed than other springs on this list, Harbin maintains a peaceful atmosphere through mindful visitor policies.

The heart-shaped warm pool, hot pool, and cold plunge create the perfect circuit for hydrotherapy. Surrounded by 5,000 acres of pristine nature, you can hike to waterfalls between soaks or simply relax on the sundeck.

Though I initially worried rebuilding would change Harbin’s character, my recent visit proved the essence remains – especially midweek when fewer visitors make the journey. The clothing-optional policy and focus on mindfulness creates a uniquely accepting environment. Their reservation system helps maintain the uncrowded atmosphere.

7. Wild Willy’s Hot Springs: Eastern Sierra Magic

Just outside Mammoth Lakes lies a surreal landscape where geothermal waters bubble up through a high desert meadow. Wild Willy’s (also called Crowley Hot Springs) features a heart-shaped main pool large enough for several people without feeling crowded.

Getting here requires navigating an unmarked dirt road and then walking a quarter-mile on a wooden boardwalk that protects the delicate meadow ecosystem. This minor challenge keeps away casual tourists, especially during weekdays.

My most magical experience here happened during a winter full moon when steam rose from the 95-degree water into the freezing night air while the Sierra Nevada mountains glowed silver in the moonlight. Though more people know about Wild Willy’s than in years past, visiting during shoulder seasons or midweek still offers tranquil soaking. Always pack out all trash and respect this fragile environment.
