Decades ago, Galissas was considered Syros' rock district. Nowadays, there is little left which stands as a reminder of that era. Galissas is on the western side of the island and 7km from Ermoupoli.

Galissas' growth in tourism is confirmed by its ever expanding list of hotels, restaurants and camping sites. Here you'll also find Galissas beach, Agia Pakou Hill (which has its own little church) and the Cave of Agiou Stefanou.
