Switzerland
St. Moritz operates at 1,822 metres elevation and the sauna culture here is unapologetically luxury-oriented. Badrutt's Palace Hotel and Kulm Hotel St. Moritz anchor the high end, with multi-room sauna landscapes, outdoor heated pools, and cold-plunge facilities that benefit from the thin Alpine air. The Engadin region's crystal-clear light and low humidity mean outdoor sessions feel different from lower-altitude venues — the contrast between a 90°C sauna and a -5°C outdoor terrace is among the sharpest available in any European city. Smaller venues like Kempinski Grand Hotel des Bains and Hotel Monopol fill out the mid-tier. Day passes are standard practice at resort spas; book well ahead for any December–March or July–August window.
