The waterfall Háifoss is situated near the volcano Hekla in the south of Iceland. The river Fossá, a tributary of Þjórsá, drops here from a height of 122 m. This is the third highest waterfall of the island.
From the historical farm Þjóðveldisbærinn Stöng, which was destroyed by a volcanic eruption of Hekla in the Middle Ages and reconstructed, it is possible to hike to the waterfall along the Fossá (5 to 6 hours both directions). Above the waterfall, there is also a parking lot, so the hiking can also be made in the other direction.
