CASCADA Thermal Springs + Hotel

CASCADA Thermal Springs + Hotel is an adults-only hotel spa on NE Alberta Street in Portland, built around a set of vitality pools. It operates as both a hotel and a day-spa destination, so non-guests can buy a day pass to use the thermal springs without booking a room.

The day pass runs $100 and grants access to the pools; a minimum age of 21 applies throughout the property. Beyond soaking, the spa offers treatments, with massages starting at $180, for those who want bodywork added to a soak. The property also has a restaurant component, with Chef Megan Sky's kitchen focused on regionally sourced, preservative-free food made without seed oils.

CASCADA positions itself as a design-forward retreat, pairing the pools and spa with hotel rooms for those who want to extend the visit overnight. It's been covered by outlets including Travel + Leisure, Forbes, AFAR, Sunset, Condé Nast Traveler and Esquire. Walk-ins are welcome for the day pass, making it accessible to locals and visitors alike who aren't staying at the hotel.

Given the upscale price tier and the $100 entry fee for pool access alone, this reads as a splurge rather than a casual soak, more aligned with a special-occasion visit or a stop paired with dinner at the on-site restaurant. Hours aren't published, so calling ahead or checking the website before heading over is the safer bet.
