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. According to legend, the first Viking settler in the area, Þrasi Þórólfsson, buried a treasure in a cave behind the waterfall. A local boy found the chest years later, but was only able to grasp the ring on the side of the chest before it disappeared again.
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.
