Oslo Badstuforening Hvervenbukta

At Hvervenbukta, a sandy bay in Nordstrand/Ljan in the south of Oslo, the Oslo Sauna Association runs two self-service mobile saunas, Hugin and Munin, in the garden of the café Anne på Landet. Each takes five people for 90-minute sessions, about 30 metres from a beach where the fjord can be swum year-round. The guest who books cleans and locks up after the session. A shared session costs NOK 120 for members and NOK 200 for others, with a silent communal session on Hugin.
