1. Take a Sauna Deep Underground


What is it? Hidden in the forests between Borlänge and Ludvika lies a former iron ore mine that operated for centuries until its closure in 1968. Two decades later, a group of locals began illegally exploring the abandoned mine tunnels and stumbled upon a hidden treasure. Today, Äventyrsgruvan (The Adventure Mine) is a fully legitimate attraction that continues to evolve, offering everything from an underground sauna and diving to via ferrata routes and zipline adventures.
Why go? Ever tried sauna bathing and cold plunging 80 metres below ground? Probably not. This is a truly one-of-a-kind experience. Accompanied by a guide, you'll descend into the mine, passing remnants of its industrial past and navigating dark tunnels lit only by headlamps. Then comes the reveal: a sauna beside crystal-clear turquoise spring water, framed by soaring rock walls. A sauna master leads the ritual, punctuated by invigorating dips in the mine's four-degree waters.
Don't miss: Concerts held inside the mine, where the cavern's remarkable acoustics create an unforgettable atmosphere. Special performances take place on Walpurgis Night and St Lucia's Day, alongside other events throughout the year.
Krongruvvägen 50, Idkerberget. The four-hour sauna experience, including a guided mine tour and a cheese and charcuterie board featuring local produce, costs SEK 2,450 per person. adventuremine.se
