Beach Katsouni is located 9 km east of Mandraki and a couple of km from Paloi. It is the largest beach of Nisyros and consists of sand, pebbles and rocks offering visitors a quiet refuge amidst the beautiful surrounding. In close distance is the cape Katsouni, which is also a nice place for fishing. The cave is another interesting tourist site that is waiting to be explored. There are no tourist facilities here, the beach is completely unspoilt.
