Kastos is the sister island to Kalamos and lies parallel to its larger sibling. Port Kastos is the only village on the island but there are a number of anchorages dotted around the coast that can be used in the summer.

Port Kastos is a charming little village that is much liked by visitings ailors and does its best to keep them coming back, year after year.  The inner harbor is where the local fishermen moor their boats. They congregate in the shade in the adjacent square to mend their nets.  Port Kastos has a few decent tavernas, a couple of shops and not much more.

On the west side of Kastos, the indented bay of Port Sarakiniko is a lovely anchorage. Other places to consider stopping on a Port Kastos yacht charter for a lazy afternoon of swimming and snorkeling in crystal clear blue green waters are South Bay, Southeast Bay, Prasonisi Cove and the Northeast Coves.
