Begin your day at one at one of the cafes in the main town, preferably a bit further up, close to the castle, in order to enjoy the view of the harbour as well as the island of Paros in the distance.
A great choice for your swim is at the beach is Plaka (after Maragka). It is only 9 km away from the main town and is linked with frequent bus routes to and from the Chora. Moreover, you can enjoy water sports but also take some wind surfing lessons safely. Do not miss the chance to be at Portara (main town) to view the sunset. Portara are the remains of a temple, the construnction of which began in 530 B.C. but was left incomplete.
Directly after that, you can enjoy your drink at one of the bars found in the many narrow alleys of the castle.
