From luxury mineral resorts in Calistoga to remote desert soaks, here are the best California hot springs worth a road trip.
From luxury mineral resorts in Calistoga to remote desert soaks, these are the California hot springs worth planning an entire road trip around.
California is home to some of the most diverse and spectacular hot springs in North America. Thanks to the state's volcanic history and active geothermal systems, natural mineral-rich waters bubble to the surface in nearly every region—from the wine country hills of Napa Valley to the rugged cliffs of Big Sur and the high elevations of the Sierra Nevada.
For travelers, that means there isn't just one type of hot spring experience. You can spend the weekend at a luxury resort with spa treatments and fine dining, soak in a historic mineral pool that has welcomed visitors for more than a century, or hike deep into the wilderness to reach a remote spring surrounded by mountains and desert landscapes.
Whether you're planning a wellness getaway, a romantic weekend, or a road trip across the Golden State, these are the best hot springs in California and what makes each one worth visiting.
Why California Has So Many Hot Springs
California sits along a complex network of tectonic plate boundaries and volcanic regions. This geological activity heats groundwater deep underground before it rises back to the surface through natural fissures and faults.
The result is an extraordinary variety of hot springs throughout the state. Some emerge as undeveloped natural pools hidden in the backcountry. Others have been transformed into mineral spas and resorts that combine geothermal soaking with luxury accommodations.
The mineral content varies from spring to spring as well. Some waters contain high concentrations of sulfur, silica, calcium, magnesium, and lithium, all of which contribute to the unique feel and reputation of each location.
While many visitors seek hot springs for relaxation, the experience is also about connecting with the landscape. Few activities allow you to sit in naturally heated water while overlooking vineyards, deserts, forests, mountains, or the Pacific Ocean.
Best Luxury Hot Spring Resorts in California
Indian Springs Calistoga
If there is a single hot spring destination that defines luxury soaking in California, it is Indian Springs Calistoga.
Located in Napa Valley's famous spa town of Calistoga, the property draws water directly from geothermal sources that emerge at temperatures exceeding 100 degrees Fahrenheit. The resort's massive mineral pool, one of the largest in California, has been a centerpiece of the property since 1862.
The experience here feels timeless. Guests spend the day moving between mineral pools, steam rooms, and volcanic ash mud baths before relaxing among palm trees and gardens. The setting combines classic California resort culture with the area's long history as a wellness destination.
For travelers seeking their first California hot spring experience, Indian Springs is often the benchmark against which other resorts are measured.
Best for: Luxury getaways, couples, Napa Valley vacations
Fairmont Sonoma Mission Inn & Spa
A short drive from Calistoga, the Fairmont Sonoma Mission Inn & Spa offers one of the state's most sophisticated thermal spa experiences.
The property sits atop an ancient geothermal source discovered more than a century ago. Today, the naturally heated mineral water feeds multiple pools, whirlpools, and bathing facilities.
What sets the Fairmont apart is its emphasis on spa rituals. Guests can experience Roman-inspired bathing circuits, steam therapies, and hydrothermal treatments that create a full wellness-focused itinerary rather than simply a place to soak.
Combined with Sonoma wine country, world-class dining, and luxury accommodations, it's one of the most complete hot spring destinations in California.

Many visitors combine their stay with hiking, fishing, backpacking, and exploration of nearby alpine lakes.
The journey itself becomes part of the experience, making Mono Hot Springs especially appealing for road trippers and outdoor adventurers.

California also offers numerous undeveloped hot springs for travelers seeking adventure. Popular examples include Deep Creek Hot Springs near San Bernardino, Travertine Hot Springs near Bridgeport, Wild Willy's Hot Springs near Mammoth Lakes, Buckeye Hot Springs in the Eastern Sierra, and Sespe Hot Springs in Los Padres National Forest.
