Like Goðafoss, the Aldeyjarfoss waterfall, situated on the Skjálfandafljót River, is fed by the Vatnajökull glacier. The water flows into a narrow passage before dropping 20 meter into a wide basin, surrounded by beautifully formed basalt columns, which are a part of a lava field, named Suðurárhraun, which was originally formed by eruptions, around 9500 years ago.
Aldeyjarfoss waterfall is situated in the valley of Bárðardalur in the north of Iceland at the northern part of the Sprengisandur Highland Road. From Akureyri head east on the Ring Road 40km to Godafoss waterfall and then turn right onto 842 going south. Aldeyjarfoss is not terribly difficult to get to, but does involve about a half hour on an unpaved road, and then about another 10 minutes on F26 that requires a 4 wheel drive vehicle. You can stop at the beginning of F26 road, if you don’t have a 4×4 and hike the last 3 km to the waterfall.
