End your stay with an optional additional activity: Traditional smoke sauna experience to unwind and reflect. Smoked Sauna is the traditional, ancient type of Finnish sauna that has no chimney. Wood is burned in a large stove for several hours, allowing the smoke to fill the room and escape only through a small hatch and the door. Once the fire dies down, the smoke is cleared out, leaving behind a sterile, deeply relaxing room with a distinct aroma of birch wood and tar.
