Kozjak beach is 800m long and is located on the south side from where there is a stunning view of most of the island. The coast is paved and pebbled, and the sea is sandy. The beach is interesting because half of the beach is in the sun during the day and half in the shade. The most interesting features are rocks and stone that is like a grindstone. Within the beach there is a historic Venetian fortress Kaštelina built in the early 17th century. Kozjak beach is very shallow and suitable for swimmers of all ages.
