Háifoss Waterfall, one of the tallest waterfalls in Iceland, is located near Hekla volcano in the Thjorsardalur valley on the edge of the Southern Highland. As the Fossa river flows through the valley, it splits into two tributaries, forming Háifoss (122 meters) tall and the neighboring Granni (101 meters) before feeding into the Thjorsa River. Both can be seen from a viewing point as well as several unnamed waterfalls.
