Skógafoss a magnificent waterfall in the Skógá River, on the south coast of Iceland. It is located on the cliffs of the former coastline. After the coastline had receded seaward the former sea cliffs remained, parallel to the coast over hundreds of kilometres, creating, with mountains a clear border between the coastal lowlands and the Highlands of Iceland.

The Skógafoss waterfall is one of the biggest waterfalls in Iceland at a width of 25 metres, and a drop of 60 m. Due to the amount of spray the waterfall produces, a single or double rainbow is often visible on sunny days.
