Teth Sauna can be found on the edge of the quaint fishing village of Collieston, Aberdeenshire, where the sandy dunes of Forvie Nature Reserve meet the rugged cliffs of the North. The natural sheltered bay creates a perfect spot for wild swimming in these otherwise untamed waters. Balancing the invigorating chill of the wild North Sea, Teth, the Gaelic word for hot (pronounced “cheh”), captures the essence of the sauna experience.
