The story of Sulak Canyon
The Sulak River has cut a gorge up to about 1,900 metres deep through the mountains of Dagestan, deeper than the Grand Canyon in the United States. Its colour comes from minerals in the water and the dam lakes along its course.
The village of Dubki sits right on the edge, with viewpoints, swings and glass platforms over the drop. Below, boats run through narrow walls of rock on bright turquoise water.
