Sail to the island's two impressive caves, accessed only by sea. One of these is the cave of Toihos in the north-west of the island near Aspros Kavos, full of stalactites, a popular spot for fishing boats to hide during rough seas. The other cave is Fokospilia (seal cave), found in Moschonas on the eastern coast. It is outstanding in its natural beauty and colours of the water. There are daily boats that visit the caves.
