At Sk贸gafoss in Sk贸gar, Iceland, the heavy amount of spray that the waterfall produces makes a sunny-day rainbow sighting very likely.
Sk贸gafoss flows from not one, but two glaciers (Eyjafjallajokull and Myrdalsjokull). According to legend, a viking named Thrasi hid his chest of gold under this stunning waterfall.
