It is practically impossible to discern the mouth of the Gulf of Gera from out at sea. An obelisk known as “o kalogeros” (the monk) serves as a seamark, giving off beacon signals indicating the location of mouth of Gulf.

There are no shoals in the gulf mouth area and the waters are 17m deep. The mouth is approximately 200m wide.

One should be cautious when sailing off the Cape of “Kavourolimni” as the shallow reefs extend for 50m toward the mouth of the gulf.
