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 Thorsborne Trail is a 32km point-to-point trekking route along the eastern coastline of Hinchinbrook Island, within Girringun National Park, Queensland. Running between Ramsay Bay in the north and George Point in the south, the trail traverses a diverse tropical landscape of mangrove systems, granite headlands, and rainforest. Hinchinbrook is an uninhabited wilderness island, accessible only by organized boat transfers from the mainland hubs of Cardwell or Lucinda. The route follows the Hinchinbrook Channel side and the open Coral Sea, passing significant features like Zoe Falls and the granite peaks of Mount Bowen.
