Langfossen is a waterfall located in Etne Municipality in Vestland county, Norway. The waterfall is located about 5 kilometres southwest of the village of Fjæra. The water falls down a towering mountain, a total distance of about 612 metres before the water leaps out into Åkrafjorden at the base of the mountain. European route E134 runs along the base of the waterfall, making access very easy. The World Waterfall Database declared this waterfall to be one of the "best in the world".
