About Samos

Samos is greener than most Aegean islands, its slopes of pine and vines rising above valleys such as the Ampelos gorge and towns such as Pythagoreio, with its harbour and the ancient tunnel of Eupalinos. The Heraion, a UNESCO-listed sanctuary to Hera, and the archaeological museum in Vathy cover the island's ancient role, while beaches on the south coast and around Kokkari offer swimming and windsurfing. May, June and September balance warm sea, walking weather and quieter tavernas and roads.
