Xylokastro is a seaside town or village and former Municipality of Corinth in the Peloponnese.
Geographical features include a large beach and semi-anechoic forests in diverse terrain, scattered with early churches and elements of early settlements and religious sites. It has separated the upper and lower coastal streets and forms a Mediterranean tourist village in the Gulf of Corinth.
Xylokastro is on the shores of the Corinth Gulf, 30km southwest of Corinth, near the Trikalitiko River. In addition to the narrow strip of land along the coast, where the city of Xylokastro is located, the municipal unit is mountainous. The Greek Highway 8a (Corinth – Patras) passes through the city.
