Seljalandsfoss is a stunning waterfall and also one of the most popular highlights in Iceland. Take your time to walk along the path and pass behind this 65 metres high waterfall. If you walk a bit further after Seljalandsfoss for about 10 minutes, you reach Gljúfrabúi, a beautiful waterfall hidden in a gorge/cave.

Tip: You can stay the night at the nearby campsite and visit the waterfalls before or after the crowds.
