Gullfoss is a waterfall located in the canyon of Hvítá river in southwest Iceland. Gullfoss is one of the most popular tourist attractions in the country. The wide Hvítá rushes southward. About a kilometre above the falls it turns sharply to the right and flows down into a wide curved three-step "staircase" and then abruptly plunges in two stages (11 m and 21 m) into a crevice 32 m (105 ft) deep.
