Hengifoss

Hengifoss is a 128-metre waterfall on the Hengifossá river, dropping into a canyon whose walls are one of the most visually striking geological features in Iceland: clearly visible horizontal bands of red iron-rich soil alternate with layers of black basalt, the result of successive lava flows separated by warm periods when fertile soil developed between eruptions. The red and black striped cliff face behind the falling water creates a compositional backdrop of extraordinary power.

The hike to Hengifoss begins at the car park on the western shore of Lagarfljót lake and climbs steadily for about 2.5 km (allow 45–60 minutes) with expanding views over the lake and valley. About halfway up, a signed detour leads to Litlanesfoss — a smaller but exquisite waterfall framed by a perfectly regular colonnade of tall basalt columns that arch over the stream like a natural cathedral. Most hikers visit both falls on the same outing. The trails are well-maintained and clearly marked.

Hengifoss is located near Egilsstaðir in East Iceland, approximately 6 km from the town of Fellabær. It is accessible year-round on a paved road, though the upper sections of the hiking trail can be icy in winter and trekking poles are recommended from November through April. The trail and falls are free to access; the car park area has toilet facilities.
