Čiovo, a mountainous island in central Dalmatia, extends eastward and encloses the Kaštela bay. Well-known towns and villages on the island include Trogir, Arbanija and Slatina, as well as Okrug Gornji and Donji. The island is connected to the mainland by a small bridge in the old center of Trogir. Okrug, located on the western side of Čiovo, is made up of two districts, the Upper and Lower. The name of this place comes from the Croatian word for "circle" since both places are distributed along a circular bay. The numerous bays and beaches have made this area one of the most popular tourist destinations in Croatia. Along with beautiful spots for swimming, a wide range of sporting activities are offered on the beaches, such as scuba diving, water skiing, paragliding, as well as fitness centers and tennis courts. After a long day spent relaxing in the sunshine, there are numerous restaurants and bars along the coast, with great music, for a fun night out.
