Adventuremine Äventyrsgruvan

Discovering the Depths of Tuna Hästberg

Nestled in the quiet village of Tuna Hästberg between Borlänge and Ludvika in Dalarna, Adventuremine Äventyrsgruvan occupies a former iron ore mine closed in 1968. This underground world stretches hundreds of meters into the mountain, featuring massive chambers, narrow passages, and pristine lakes preserved in a cool, stable environment. The site's transformation from industrial relic to adventure destination highlights its preserved artifacts like old rail tracks, ladders, and mining carts, all intact due to the oxygen-poor conditions.

Guided Journeys into the Unknown

Guided tours descend via a 110-meter staircase in the old personnel shaft, leading to Stora Salen, an enormous rock chamber illuminated by torches. The standard hiking tour offers a 1.5-2 hour exploration with stories of the mine's past, magnetic iron ore hunts, and fika breaks in a former dynamite storage room. More intense options include navigating ortsystem passages and brytrum chambers, evoking scenes from epic fantasies with echoing acoustics perfect for events like Lucia and Valborg celebrations.

Adrenaline-Fueled Challenges

The signature adventure tour spans 4 hours, incorporating via ferrata climbing systems suitable for beginners and experts alike, suspension bridges, and ziplines over voids. Participants tackle metal ladders and traverse the mine's driest deepest sections at 80 meters down. Weight limits apply (36-120kg for harnessed activities), ensuring safety in this physically demanding yet accessible setting. Gloves protect hands on cold steel, while the constant 4°C demands layered clothing like base layers, sturdy boots, and hats.

Underwater Explorations and Rituals

Advanced divers with PADI Advanced Open Water or equivalent experience plunge into crystal-clear underground lakes at 4-5°C depths up to 21 meters, guided through overhead environments with over 7km of fixed lines. Visibility exceeds 30 meters year-round, revealing preserved relics like doors and wagons. Complementing the action, the Lady of the Mine sauna ritual offers 3.5 hours of transcendent relaxation with cold plunges, cheese platters, and charcuterie in the depths, blending recovery with the mine's mystique.

Preserving History and Hosting Events

Operators focus on safeguarding Tuna Hästberg's industrial heritage, fostering community ties while providing conferences in heated chambers and unique performances leveraging natural acoustics. From family outings to corporate retreats, activities adapt to physical abilities, with no upper age limit beyond fitness considerations. Pregnant visitors beyond 16 weeks are restricted, and minors under 15 require guardians. This multifaceted site merges Dalarna's mining legacy with modern adventure.
