Many people only know sauna from their local gym.
Not many people know the full practice of sauna – hot, cold, rest, rehydrate, and repeat – the thermic cycle.
Our guides will teach you how to sauna correctly, soaking up the heat and the cold for the full experience.
This experience is guided as much or as little as you would like. Our guides are happy to help!
