Seljalandsfoss Waterfall in South Iceland is a breathtaking attraction on the Seljalandsá River, about 30 km west of Skógar. At this site, you can admire its thin cascade and follow the footpath behind the falls for an unforgettable view. Activities include photography, hiking to nearby waterfalls such as Gljúfrabúi, and exploring the scenic route toward Thorsmörk. Notably, Seljalandsfoss is the only known waterfall in Iceland where visitors can walk behind the flow, making it a favorite subject in books and calendars. Caution is advised in winter, as icy paths and falling chunks of ice can make the area hazardous.
