East of Cape Skinari, on the northern part of the island, are the Blue Caves. A series of geological formations have created the seascape. Natural arches have been carved out by erosion, but these caves are most famous for the color of the water in it's deepest hollows, a deep azure color which is most striking in the morning when the light is at it's brightest, hence the name Blue Caves. Kianoun cave is the biggest of the caves. In order to reach there you can hire a boat or go on a tour.
