Springs
Farris Bad
Vestfold
Norway's only spa built directly on a natural mineral-rich spring, where water that fell as rain roughly 20 years earlier rises from 55 metres beneath a forested moraine hill in Larvik.
Jotunkjeldene
Bockfjorden, Svalbard · 20°C
The northernmost thermal springs on land on Earth, bubbling year-round at around 20°C on the shore of a remote Arctic fjord in Svalbard, reachable only by expedition cruise.
Manshausen Island
Steigen Archipelago, Nordland · 80°C
A restored 19th-century fishing station on a tiny island in the Steigen archipelago, north of the Arctic Circle — with a dock sauna giving directly onto the fjord waters of Nordland.
Soria Moria Sauna
Hardanger, Vestland · 80°C
A fjord-side sauna in the Hardanger region of Norway — named for the mythical castle of Norse legend — where wood-fired heat meets the cold waters of Hardangerfjord beneath cascading waterfalls.
The Bads — Floating Sauna
Møre og Romsdal · 80°C
A floating wood-fired sauna on the waters of a Norwegian fjord in Møre og Romsdal — the Norwegian badstue tradition at its most elemental, with cold fjord plunges between heating rounds.
Trollkjeldene
Bockfjorden, Svalbard · 28°C
The larger and warmer of Svalbard's twin Arctic thermal springs, reaching up to 28°C amid sweeping travertine terraces eight kilometres up the Bockfjorden valley from its sister spring Jotunkjeldene.
