Bellevue, WA
Vihta Sauna offers authentic Nordic outdoor wood-fired sauna sessions on the shores of Lake Sammamish in Bellevue. Fresh eucalyptus vihta (birch whisk), real steam, and social sauna sessions in a genuine Finnish tradition. Guests cool off with a direct cold plunge into Lake Sammamish between rounds. Book online; social sessions run 75 minutes. Swimsuits are typically required in the sauna — not a nude jjimjilbang; confirm dress code at vihtasauna.co if that matters to you.
Other spots in the same area or with a similar vibe — always double-check hours and access on the venue's site.
