Alkyonides Gulf

Three regional units surround the gulf: Corinthia to the south, West Attica to the east and Boeotia to the north.

Except for the Megaris Plain to the southeast, mountains surround the gulf.

These mountains include the Geraneia to the south, Pateras to the east, Cithaeron to the northeast and Mount Helicon to the north.

These islands include Daskalio, Prasonisi and Zoodochos Pigi.

More islands, including Fonias and Makronisos lie to the extreme north.
