Fimmvörðuháls Trail

Between the Glaciers. Fimmvörðuháls is arguably Iceland's most famous wilderness day hike, a 25km trail that climbs from the coast at Skógar, over a high pass between the Eyjafjallajökull and Mýrdalsjökull glaciers, and descends into the lush Þórsmörk valley. It is widely cited for its 'Waterfall Way'—a series of more than 20 waterfalls along the Skógá River—and for crossing the site of the 2010 volcanic eruption, where trekkers pass the world's two newest craters, Magni and Móði.

One of the most frequented day hikes from El Chaltén, the route to Laguna Torre leads to a glacial lake at the base of the Torre massif. The 18 km out-and-back trail follows the Fitz Roy River valley, moving through sub-antarctic forests of ñire and lenga. The terrain is primarily well-maintained gravel paths and packed dirt, with a short initial ascent followed by mostly level walking through the glacial valley. The destination offers direct views of Cerro Torre (3,128m) and the Adela range, with icebergs frequently calving from the Torre Glacier into the lake.
