CASCADA: Portland’s Underground Wellness Wonder

Writer was hosted.

In the heart of Portland’s vibrant Alberta Arts District lies Cascada, the city’s first underground thermal springs and spa hotel. This adults-only retreat with its lush botanical and modern aesthetic offers a unique and upscale experience that creates the perfect environment to unwind and recharge.

Shortly after its opening in March 2025, I spent two days at Cascada, immersing myself in its accommodations, pools, spa services and the surrounding neighborhood.

Whether you’re a local wellness seeker or visiting Portland for a girlfriend getaway, here’s why you should plan time here!

Located 15 minutes from downtown Portland, Cascada boasts 100 guest rooms alongside five rejuvenating thermal pools, a sauna, steam room, full-service spa and fitness center. This self-care haven sits in the Alberta Arts District, a vibrant community where cultures and ethnicities mix to create unique, and walkable, venues for art, food, shopping and entertainment.

What to Expect in The Sanctuary

Venture beneath the surface at Cascada to discover a haven of saunas, mineral thermal springs, and a range of soaking tubs. Tailor your experience for optimal wellness – a recommended detox sequence includes sauna, cool shower, and the warm ambient pool. The underground atmosphere is peaceful, with low lighting, gentle water features, and enforced silence. For guest privacy and undisturbed relaxation, cell phone use is not allowed.

The Sanctuary underground hydrothermal spa was really the highlight of my stay. During my two-night stay, I had only planned to use the space once, but ended up soaking after my flight (great cure for jetlag) and again the next evening. The baths of varying temperatures (thermal, hot, ambient and cold plunge) are a cure for aching muscles. The low light and enforced quiet truly allow you to decompress and relax.

SheBuysTravel Tip: Bring your own swimsuit and soak alone: while you can bring a companion to soak, the experience is best enjoyed solo to limit outside conversation.

Alberta Coffee on the first floor has the usual assortment of caffeine-inspired beverages and a cold case with buy-and-go snacks and sandwiches. Options include local favorites including protein pudding, Japanese egg salad and nutrient-rich beverages.

In-hotel dining currently includes two options, with a third restaurant planned when the Secret Garden opens:

  • Alberta Coffee: Coffee, breakfast and a grab-and-go 24/7 case.
  • Terra Mae: Buzzy main restaurant blending Portuguese and Japanese fusion dishes serving dinner Wednesday through Saturday evenings from 5pm. Reservations recommended.

Alberta Street has lots of walkable restaurants nearby. I enjoyed the food truck across from the hotel as well as Pine State Biscuits, a popular breakfast and lunch spot.
