The Kozjak mountain is visible on the north of the Kastela town, a few kilometres northeast of Split. On the south side of Kozjak there are steep cliffs, and the mountain gradually becomes a highland area on it’s northern side, also known as the dalmatian Zagora.

Of the three highest mountain peaks, the tallest is the Veli Vrj on 779 meters of altitude. In the past the peak’s name was also St. Lucas and Kozjak.

Kozjak is well known for the big rock on it’s south side that runs continuously for 16 kilometres in the east – west direction. Even though it is not particularly high, this is the longest mountain rock in Croatia.

There are many hiking trails on the mountain, more than 80 kilometers long. There are 4 mountain shelters on Kozjak, which is most mountain shelters on one mountain of the same or similar size. Close to mountain shelter Malacka there are well known rock-climbing sites that are not complicated, and are interesting to the professionals, but also appropriate for the beginners as well.

On the southern slope a wide variety of Mediterranean plant life can be found, but the mountain is also known for the orchids growing in the higher areas. At the times of the Roman empire, Kozjak was covered with forests, and there is also an archaeological site that has the carving in stone depicting the Illyrian god Silvan, protector of the pastures and forests, on the northeast part of the mountain, above the Kastel Sucurac.

It is supposed that the name of the mountain has developed from the translation of the name from the greek, like the old greek name Tragurion for today’s Trogir, of the greek tragos for a goat.

From Kozjak the magnificent landscape views open in front of you and they display the Kastela bay, the Split Peninsula, Marjan hill, Trogir and the islands of the region – Ciovo, Solta, Brac, Hvar and Vis.
