Mountain sauna in Britain means the Highlands, with the Peak District holding the English end. Kingussie, Aviemore, Ballater and Ballachulish put a stove within reach of the hills.
Nearly all of these are wood-fired and outdoors, and several travel to the site rather than sit on it. Expect a track rather than a car park, and dress for the walk between heat and air.
In the United Kingdom, 12 of the curated saunas fit this cut. See the full the United Kingdom country guide for every venue, or keep scrolling for just the mountain saunas.
