At the villages on the south coast like Limni Keriou, Agios Sostis and Laganas you can book a boat tour along the indented coastline in the far south of the island.
The white cliffs soar to 300 metres and at their base are small sea caves and natural arches.
At one the boat will lower a ladder for you to swim in the sea, which has a radiance caused by the purity of the water and the sun hitting the white rocks.
