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.

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.
