Zaostrog is tourist settlement on the Makarska coastline, about 35 km from Makarska. Today Zaostrog, as a tourist settlement of the southern Makarska coast, is completely oriented to the development of tourism. Zaostrog is settled permanently by some 350 inhabitants, mostly employed in hotel and restaurant services and tourism. The town has around 750 beds available in private residences, villas, and boarding houses, with a further 600 places at the Auto Camp "Viter". 

Located in an evergreen valley and surrounded by the foothills of the Biokovo Range, with spectacular beaches, and with a rich historical and cultural tradition, in the immediate vicinity of numerous attractive destinations for excursions, Zaostrog is an attractive place for a pleasant vacation. It was mentioned for the first time in 1494, but this area was inhabited in the ancient past, as is shown by a granite handle quem from the late Stone Age, discovered at Viter, the hill about Zaostrog, in 1953. Zaostrog was also settled by the ancient Illyrians, as is confirmed by the numerous cemeteries of burial mounds. A rich cultural life existed at Zaostrog in the period of Roman rule, as can be seen from the numerous classical monuments, particularly the stone ones: a relief of dancers and flute players in Illyrian attire, a relief showing the deity Mithras, and two tombstones. After the arrival of the Croats in the 7th century, the settlement received the Slavic name Ostrog, mentioned around 950 AD by the Byzantine Emperor Constantine Porphyrogenetus as one of the four fortified cities of the "Pagania" of the NeretvanPrincedom (Mokron, Berulia, Ostrok, Labinetza). Medieval Ostrog (meaning "fortress") was located at a high point below Mali Viter, and later a new settlement called Zaostrog developed below the hill of Šapašnik on the north of the Zaostrog plain and to the northwest of the town cited by Porphy rogenetus.
