Located in the high Sonoran Desert foothills of Arizona, this stunning spa resort is named after the 12 million year-old granite boulder formations that dot the dramatic desert landscape – plus provide panoramic views. Adobe and hacienda-inspired accommodations provide a stylish and spacious stay, while a 33,000 square foot luxury spa awaits to pamper. Choose from any of the many garden-to-spa treatments utilizing seasonal botanicals from the property’s own Organic Garden. Many are rooted in centuries-old Native American traditions.

Or, reserve the spa’s private, outdoor Water Lounge to experience ultimate relaxation with an in-water Watsu Massage (50 minutes). You’ll float weightless through the warm, shallow water as your therapist gently guides you with rhythmic movement, pressure point massages and gentle stretching. Stemming from the words “water” and “shiatsu” (a type of traditional Japanese massage that uses acupressure to promote relaxation) Watsu massages can help reduce muscle tension, anxiety, chronic pain, fibromyalgia and even discomfort during pregnancy.

Best Hydrotherapy Spas in the United States: The Springs Resort // Pagosa Springs, Colorado

If soothing geothermal soaks, rooms-with-a-view of the San Juan River and ultimate relaxation all sound appealing, than The Springs Resort has your name on it. Boasting wellness at its core, literally, this picturesque spa resort is located in Pagosa Springs: the world’s deepest geothermal spring at a whopping 1,002 feet deep. The Eiffel Tower could fit into it.

Discovered by the native Southern Ute tribe centuries ago, the word “Pagosa” comes from the Ute word meaning “healing waters.” And it’s no wonder, as mineral-rich waters counting the likes of potassium, magnesium, zinc and iron promote a bounty of wellness benefits. Think healthy skin, decreased inflammation, lower blood pressure, strengthened immune response, improved sleep and increased energy, to name a few.

A bubbling Mother Spring feeds 25 soaking pools along the San Juan River, where guests can take the plunge – a cold plunge, that is – and reap the benefits of contrast bathing. Your soak-and-stay experience includes 24-hour access to all natural pools, in addition to daily in-water activities like Aqua Yoga and Aqua Sound Bathing. Plus, the ability to soak pre-check in and post-check out.

The Hydro Rock body treatment combines toxin-removing lymphatic exfoliation with circulation-boosting hot and cold hydrotherapy. Book the H20 Inspiration for a hydrating Moroccan oil hair masque and full-body exfoliation, followed by a calming Ambient Rain shower and RiverBath soak.

Speaking of the latter – three Kohler Bathing experiences allow you to soak into an even deeper state of zen. All utilize mineral-rich thalassotherapy and moisturizing marine extracts for therapeutic relaxation, accompanied by full-body exfoliation and Vichy Shower rinses. Make sure to arrive to your hydro treatment early, as you’ll want to take advantage of the spa’s warm relaxation pool (complete with a cascading, 8-foot waterwall), whirlpools, cold plunge pools, saunas, steam rooms and unique Kohler showers.

Forty minutes from Alaska’s capital of Anchorage lies the chateau-style mountain resort of Alyeska – and its brand new, adults-only Nordic Spa. A destination for ski and summer seasons alike, the spa comes as a welcome addition for guests looking to unwind after embarking on any number of adventurous activities. Officially opening July 2022, Alyeska’s year-round Nordic Spa marks the first of its kind in Alaska.

A vast series of outdoor hydrotherapy pools – clocking 50,000 square feet – await guests ready to soak in some R&R. Cold water plunges and waterfalls, Halotherapy and Finnish saunas, aromatherapy-infused steam rooms and an exfoliation cabin featuring Alaskan sea salt are all on offer, plus heated walkways throughout the spa.

The Nordic Spa experience gives Alaskans and visitors alike an opportunity to experience the Nordic tradition of hydrotherapy, a health ritual Nordic people have practiced for thousands of years,” says Spa Manager Melissa DeRose in a press release. “Guests can cycle through stages of submersion in hot, warm, and cold water at their leisure, moving between the initial hot pools to stimulate blood flow and relax muscles, to cold, with the cold plunge waterfall to flush the body of toxins.”

Next up? A forest bathing experience debuting later this year complete with an elevated boardwalk through Chugach Forest, six outdoor hot and cold wooden tubs, two large barrel saunas built locally with Alaska timber and two Banya saunas.
