Thermal baths in Trondheim
Trondheim sits on the Trondheimsfjord in central Norway, where the Nidelva river reaches the sea. Its harbor saunas are a short walk apart: the floating ARK village and Árdna on the quay at Nyhavna, and Stu's two rooms afloat in the Brattørbassenget basin. Nidaros Cathedral is about 1.5 km south of Stu.
