Sauna Tramuntana is a Norwegian-run outdoor sauna business based on Camí de Caubet in Bunyola, at the foot of the Tramuntana north of Palma. It rents and sells mobile barrel saunas, sauna tents and cold plunges, and runs drop-in outdoor sauna and cold plunge sessions at two locations outside Palma that its site does not name. The sessions are held on a finca with a panoramic outdoor sauna, a cold-water pool, an ice-cold shower and a fireplace. Ask for the location before going.
