The Well, at Sofiemyr 15 minutes from Oslo, calls itself the Nordics' largest spa. Its nine saunas include Finnish, Japanese, banja, bio, tropical and an outdoor forest sauna, alongside steam baths, an oriental hammam, a Japanese bath house, ten pools and a cold plunge. Sauna masters lead aufguss rituals. Nudity is the norm in the saunas and steam baths, but swimwear is mandatory throughout on Tuesdays. It is adults-only and opens daily 10:00 to 22:00, with entry from NOK 525.
