Papanikolis submarine

Nidri promised boat trips. Most of them went to beaches. The MS Christina went somewhere more interesting: Kastos and Kalamos, two small islands between Lefkada and Ithaca that most visitors to the Ionians never reach. A wartime submarine cave, a surprisingly ornate church on an island of forty people, a poet’s island you can only look at from the water, and a close pass of Skorpios. Not bad for a day that almost did not happen.
