The town lies in the north of the Abruzzo region, between the Salinello and the Tordino rivers. Giulianova is split between the Paese, the historic town up in the hills, and the lido, the more recent development down by the beach.
Tourism plays a big part in the town's economy. The town, characterized by several beaches, is a summer retreat for people from large cities like Rome and Milan, as well as German and French tourists.
