Kozjak is a prominent mountain range in Dalmatia, rising above the town of Kaštela north of Split and serving as a natural barrier between the sea and the hinterland. Geologically, Kozjak is characterized by an asymmetrical structure: its southern slopes drop almost vertically toward the sea, while the northern slopes decline gently toward the karst fields of Zagora. The mountain is primarily composed of Mesozoic limestone, with its base made of flysch layers responsible for the fertility of the coastal plain below. The highest peak of Kozjak is Veli Kozjak at 779 meters, offering sweeping views of the Adriatic Sea and the offshore islands. Historically, Kozjak was of great strategic importance, evidenced by numerous medieval churches and fortifications along its ridges, often built on ancient Illyrian foundations. Along the slopes, remains of the ancient Roman aqueduct that supplied Diocletian's Palace in Split can still be found. The vegetation varies from Mediterranean macchia on the southern side to denser beech and oak forests in protected northern areas. Today, Kozjak is a popular destination for hikers and rock climbers, as its steep cliffs provide good conditions. The region is also famous for the Crljenak Kaštelanski grape variety, which is genetically identical to Zinfandel.
