Kozjak Beach is 800m long and is located on the south side with a stunning view of most of the island. The coast is paved and pebbled, and in the sea there is sand. The beach is interesting because half of the beach is in the sun during the day and half in the shade. The most interesting feature is the rocks and the stone which is like a sandstone. Within the beach is the historic Venetian fortress Kaštelina built at the beginning of the 17th century. Kozjak Beach is very shallow and suitable for swimmers of all ages.
