Fimmvörðuháls ( listen ; Icelandic for "five cairns pass") is the area between the glaciers Eyjafjallajökull and Mýrdalsjökull in southern Iceland. The route between Skógar and Thórsmörk goes through this pass and is one of the most popular walking routes in Iceland, despite being 22 km long and involving 1,000 m of climbing. At Fimmvörðuháls, there is a comfortable, modern mountain hut owned by Útivist, one of the Icelandic hiking associations. Also nearby is an older, less well-equipped hut called Baldvinsskáli. The route from Skógar is particularly beautiful, as numerous waterfalls are passed along the way. The route is only accessible between mid-June and late-August.
