Äventyrsgruvan (Adventure Mine) in Sala, central Sweden, offers a unique subterranean wellness experience 155 metres underground in a historic silver mine, where visitors descend to one of the world's most extraordinary spa environments maintained at a constant 2°C. The mine's remarkable microclimate — once used to store butter in medieval times — now hosts a sauna, rest rooms, and guided mine tours as part of an innovative underground wellness concept. Sweden's deep mining heritage and this pioneering subterranean spa concept combine to create one of Scandinavia's most original thermal experiences.

Insider tip — The Aventyrsgruvan Adventure Mine Sauna is carved into a decommissioned silver mine in Kopparberg, where the stable underground temperature of 18°C creates a striking contrast with the wood-fired sauna chambers hewn into the rock walls. This is one of Sweden's most unusual wellness experiences, combining industrial heritage tourism with Nordic sauna culture 35 metres underground. The mine's tunnels maintain constant humidity and a faint mineral scent year-round. Book in advance as guided sauna sessions are limited to small groups.
