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, Ţrasi Ţórólfsson, buried a treasure in a cave behind the waterfall.
