Litlanesfoss (also called Stuðlabergsfoss, “columnar-basalt waterfall”) is one of the most geometrically extraordinary waterfalls in Iceland. The 30-metre cascade is surrounded on three sides by soaring columns of hexagonal basalt so regular and tall they resemble the pipes of a cathedral organ — an effect that draws gasps even from seasoned travellers.
The waterfall sits on the Hengifossá river in East Iceland and is reached via the same trail as the famous Hengifoss. Litlanesfoss is actually encountered first on the hike, roughly 20 minutes from the car park. Many visitors, rushing toward the taller Hengifoss above, give it only a glance — a mistake, as the basalt columns here are far more dramatic than at most other columnar lava sites in Iceland.
The trailhead is at the Hengifoss car park near Lake Lagarfljót, about 30 km from Egilsstaðir. The path is well maintained and suitable for most walkers. Allow 2–3 hours for the full return trip to Hengifoss and back.
