From Egilsstaðir take road 1 to the north to Fellabær and there take the exit left to road 931 (Fljótsdalur). Follow the road for 32 kilometer until you see a parking at the right side of the road (gps 65.073316, -14.880282) This is the trailhead to Litlanesfoss and Hengifoss.
The hike up to the waterfall is not very difficult but goes up in the beginning. The track follows more or less the river Hengifossá. After 1,5 kilometer (30 minutes) you first will see the beautiful waterfall Litlanesfoss which is surrounded by some of Iceland’s longest basalt columns. Litlanesfoss is also called Stuðlabergsfoss which means basalt column waterfall. Litlanesfoss, in the river Hengifossá, is 35 meters high.
After Litlanesfoss you already can see the impressive Hengifoss in the distance. Unfortunately the waterfall was during our visit partially covered with clouds. From Litlanesfoss you can walk further to the base of Hengifoss but we stopped at a viewpoint after 15 minutes from Litlanesfoss because of the limited vision.
Best time to visit Litlanesfoss is early summer when there aren’t to many tourists. When you visit Hengifoss early in the morning, the light for taking pictures is on its best.
The origin of the river Hengifossá lies up at Hengifossárvatn which is located in the moorland of Fljótsdalasheiði. Hengifossárvatn is located at an altitude of 660 meter.
