This is a very nice spot about 2 km from Argostoli. Actually a nice cafeteria has been built around Katavothres that works as a romantic bar at nights. The cafe opens after 7 in the evening, which is a shame because it would also be a nice place for day coffee. There you can actually see the sea water getting into the ground, passing a wooden mill and disappearing under some rocks. This water crosses the island from underground and after 30 km it reached Melissani Lake and then pours into the sea in Karavomylos, at a place with a same mill.
