The gorge is located on the slopes of Kerkis Mountain, on the north side of the island. It ends up in the wonderful beach Megalo Seitani. Access is easy, as the road reaches the exact point where the gorge begins. The canyon holds enough water only during the winter while during the rest of the year water exists only in the "basins" that have been formed by the waterfalls. Its size is impressive, if you consider the fact that it is located in an island.
