Most people know what a hot spring consists of (a natural source of hot or warm water), and that Calistoga is known for its mineral baths of all kinds. But how does it work, and why is this relaxation practice good for you?

One thing we’ve learned is that because heated water holds more dissolved solids, hot springs have a high mineral content, which means it’s all the better for a soak. And while there may not be a ton of scientific research into its health benefits, we do know that this practice of using heat to release toxins is tens of thousands of years old.

“Quiet nights, warm soaks—welcome to Calistoga.”

With its geothermal hot springs of mineral water running underground, Calistoga has a renowned history as a place of healing. Over 50 years ago, members of the Wappo tribe were the first to discover a natural volcanic hot spring near the foot of Mount St. Helena. The rest is spa-history, with visitors coming from far and wide to take part in the curative powers of Calistoga, by relaxing in a mineral-rich hot spring or a volcanic mud bath.

The health benefits may mostly be based on anecdotal evidence, but there’s no denying the zen-like state one emerges with after a long, hot soak. If it makes you feel better and more relaxed, that’s half the battle, isn’t it? We’ve rounded up some of our favorite spa experiences that offer that famed Calistoga mineral water for your next trip to Wine Country. Get ready to soak, steam, rest, and repeat.

Calistoga Spa Hot Springs

Because one healing geothermal mineral pool isn’t enough, Calistoga Spa Hot Springs has four, and each is heated to a different temperature to suit all preferences. Have a soak in the outdoor whirlpool, which can get as hot as 104° F (perfect for year-round dips), or enjoy the Soaking Pool and its 100° F waters. If you’re itching for some exercise as well as rejuvenation, the multi-lane lap pool is heated to a cool 80° F, and the wading pool is perfect for wee spa guests.

Quick insider tip—If you have a friend who just wants to join in on their geothermal mineral pools, they can accompany you as your guest for a $25 fee.

UpValley Inn & Hot Springs

Commitment is the word we’d like to use for UpValley Inn & Hot Springs, as they are one of the few properties that have their swimming pool and whirlpool 100% fed by Calistoga mineral water drawn from their on-site geothermal well. Once you’ve soaked to your heart’s content, indulge the body a little more in their handcrafted dry sauna and steam room. And with the crisp, refreshing decor and tranquil guest rooms on-site, you’ll never have to rouse yourself from your state of zen.

Feel like exploring beautiful Calistoga, but haven’t made plans past your spa experience? Fear not, you’ll be able to with the town’s complimentary shuttle service, providing on-demand transportation to dining, wine tasting, shopping, and other Wine Country activities, creating the perfect balance of relaxation and adventure.

Dr. Wilkinson’s Backyard Resort & Spa

Founded in 1952 by holistic wellness advocate, Dr. Jon Wilkinson, Dr. Wilkinson’s Backyard Resort & Spa is an homage to his dedication to the healing waters of Calistoga. Doc recognized the restorative properties of these mineral pools, which range in temperature from 85°F to 104°F. Plush daybeds and private cabanas are on offer for guests and include towel service and access to two outdoor pools and one indoor pool.

While staying at Dr. Wilkinson’s feels like a treat enough with its mid-century modern inspired interiors and palm-fringed pools, the true star of the show is in their unique treatments. Whatever you do, don’t skip out on the Volcanic Ash Mud Bath, revered for its detoxifying properties—which you might need after a few days of wine tasting.

Indian Springs

You’ll immediately notice Indian Springs‘ eastern influence in both the spa treatments and special features around the property, like the Buddha Pond, which makes for an excellent spot to meditate, or the Himalayan Salt Room. Their signature treatment is the luxurious Indian Springs Mud Bath Ritual. You’ll soak away the day in a luxuriating mud bath while sipping on refreshing cucumber citrus water. Then it’s time to wrap up your detox with a session in the infrared sauna and, of course, a nap wrapped in a flannel blanket. Talk about pampering!

If playing in the mud isn’t quite your cup of tea, book the Pure Goat Milk and Rose Bath or the Indian Springs Salt Glo to help rehydrate your parched skin. Of course, the mineral pools are the true pièce de résistance. Swim laps in the Olympic-sized mineral pool, built in 1913, or find a secluded oasis at the Adult Pool that’s exclusively for the grown ups.

Mount View Hotel & Spa

To make relaxation an art, start your getaway at Mount View Hotel & Spa. Take a dip in the mineral waters of the hot tub and then recline in style in a cabana by the heated pool.

And for those who want a little more outside the box experience, the spa also offers Cannabidiol (CBD) oil massages. We’re willing to bet you don’t see that on the menu at your local day spa.

Mount View Hotel & Spa has also adopted a “cause integration” to hospitality and donates 50% of its profits to charity, to causes such as St. Jude Children’s Research Hospital, Ole Health, Project Ceres, and more. So if you’re civic-minded, you can relax easy knowing that while you’re laying your head at night, your stay is changing the world for the better.
