Remains of few houses and the arched bridge across the lagoon, however can be seen. Fiskardo, north of the island is a picturesque harbour town, surrounded by a thick cypress forests. A few natural wonders can be seen on this island - the caves of Melissani and Drogorati, and the sea mills at Katavothres. Melissani is actually a subterranean lake with the unusual phenomenon of when the sun shines overhead and its rays hit the crystal clear waters of this lake, the light is broken up into a myriad colours. Drogorati is a cave with amazing stalagtites.
Sea water enters openings in the rock where it disappears.
Scientists have found that this water flows northeastwards underground, to come out at Melissani. Formerly this water used to travel at such a rate that it was used to power the 2 sea mills. The island of Odysseus - a tiny, mountainous island, with lovely beaches and clear water. As Odysseus yearned to return to his home at the end of his long journies, so it is said that any visitor to Ithaki, once visited, will yearn to return. An oblong-shaped island, the most southerly and the closest to the Peloponnese.
