The Jämtlandstriangeln is a classic 47 km, 3-day loop through the high alpine mountains of Jämtland, Sweden, connecting three iconic mountain stations: Storulvån, Sylarna, and Blåhammaren. The route travels above the treeline through open fjäll terrain with spectacular views, glacier-capped peaks, clear mountain streams, and frequent reindeer sightings. Well-marked trails and comfortable hut-to-hut accommodation make this one of Sweden's most beloved and accessible multi-day mountain hikes.
