Port Kalamos is down hill from the village of Kalamos. It is the only harbor in the island and fills up rapidly during high season, when the charter business is in full swing. A yacht has four mooring options, depending on time of arrival and draft.
Kastos is located close to larger and long-established boating and holiday home destinations such as Ithaca, Kefalonia, Lefkada and Meganissi; it is separated from its neighbouring island of Kalamos by a deep channel. Just eight kilometres long and, even at its widest, only 1,200 metres across, Kastos has a huge appeal to all forms of boating and yachting enthusiasts.
