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.

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.

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.
