Sveifluháls

Sveifluháls is a long hyaloclastite ridge west of Kleifarvatn, formed by eruptions beneath glacial ice. The ridge and its surroundings combine steep volcanic terrain, geothermal alteration and younger lava fields. Marked hiking routes cross parts of the area from the Seltún/Krýsuvík side. Weather can change quickly and geothermal ground can be unstable, so hikers should stay on established paths and follow local warnings.
