Petalioi Gulf

The Petalioi Gulf (Greek: Κόλπος Πεταλιών - Kolpos Petalion) is a gulf of the Aegean Sea, Greece.

It stretches between the east coast of Attica and the south tip of the island Euboea.

It takes its name from the Petalioi islands, that are situated in the northeastern part of the Gulf, off the Euboean coast.

There are several uninhabited islands in the gulf, including the Petalioi and Makronisos.

Promontories include Strongylo and Vigla in the island of Euboea.
