Kleftiko Sea Caves
Kleftiko on Milos's south-west coast is a maze of sea caves, natural arches and grottos reachable only by boat; PADI describes underwater cliffs, hidden tunnels and schools of groupers, barracuda and octopus, with gentle currents and clear water. TripBase gives about 18 m and lists moray eels, octopus and scorpionfish.
