Now Discovering Skógafoss, Iceland.
Skógafoss is a waterfall on the Skógá River in the south of Iceland. Due to the amount of spray the waterfall produces, a single or double rainbow is normally visible on sunny days. According to legend, the first Viking settler in the area buried a treasure in a cave behind the waterfall. The legend continues that locals found the chest years later, but were only able to grasp the ring on the side of the chest before it disappeared again.
