Hekla (1491m) is Iceland’s most active volcano, which during the Middle Ages was believed to be the gate to Hell. It sits along a 40km long snow-covered mountain ridge, almost always shrouded in cloud. The volcano has had frequent eruptions in the past years (1980, 1981, 1991 and 2000) and has left thick layers of ash and pumice over the landscape. Hekla is supposedly where the term “what the heck” came from.
