PASSAGE THROUGH THE LAND OF FIRE AND ICE

Ice roads, volcanic terrain, fjords over frigid rivers… Ski-trekking across Langjokull glacier ice cap is a challenge to remember in one of Iceland’s most spectacular landscapes. Starting at Husafell, the itinerary heads towards Baldjokull, which rises 4,760ft above sea level, with views of the Thursaborg mountain range. Participants camp on ice, and the weary can take a dip in geothermal springs.
