About the location (from Wiki):
Skógafoss is a waterfall situated in the south of Iceland at the cliffs of the former coastline. After the coastline had receded seaward (it is now at a distance of about 5 kilometres from Skógar), the former sea cliffs remained, parallel to the coast over hundreds of kilometres, creating together with some mountains a clear border between the coastal lowlands and the Highlands of Iceland. The Skógafoss is one of the biggest waterfalls in the country with a width of 25 metres (82 feet) and a drop of 60 m (200 ft). Due to the amount of spray the waterfall consistently produces, a single or double rainbow is normally visible on sunny days.

At the eastern side of the waterfall, a hiking and trekking trail leads up to the pass Fimmvörðuháls between the glaciers Eyjafjallajökull and Mýrdalsjökull. It goes down to Þórsmörk on the other side and continues as the famous Laugavegur to Landmannalaugar.
