Indoor snow
Gällö · Jämtland · Sweden
The world’s longest year-round indoor ski tunnel, featuring a 1.4km subterranean real-snow cross-country loop and an indoor biathlon shooting range.
Engineered directly inside a former subterranean military cavern in Gällö (Jämtland), Mid Sweden 365 is the world’s longest indoor ski tunnel. The cavernous mountain tunnel houses a continuous 1,400-metre cross-country ski loop featuring an authentic 12-metre vertical climb and rolling elevation contours for both classic and skate techniques. Maintained at a crisp -4°C with thick, high-density machine snow, the facility includes an integrated 6-target indoor biathlon shooting range and is a globally renowned summer pre-season training hub for Olympic and World Cup Nordic athletes.
