Mosor is a high karst mountain dominating the area between Split and Omiš. This mountain is divided from Kozjak by a deeply cut area of Klis, and it spreads to the Cetina River towards the southeast. The highest peak, called Veliki Kabal, is 1339 meters above sea level, and the entire mountain is 25 kilometers long. The key feature of the area is a pronounced rocky ridge, white and bare in its limestone character, with steep rocky slopes on both sides. The northern slope is characterized by numerous karrens, deep sinkholes and karst pits, while the southern slope abounds in terraced valleys.
The main ridge consists of three sections. The ridge of the western part of Mosor spreads from Klis to Ljubljanski prijevoj. The highest peaks in this part of the mountain are Debelo brdo, Plišivac and Kunjevod. The central section of Mosor – also the highest and the most visited part of the mountain – is the area around the pronounced part of the ridge with the peaks of Ljubljan and V. Kabal as particularly prominent features. The eastern section of Mosor spreads from the mountain pass Ljuto kame all the way to the Cetina River, and its key peaks are Botajna, Sv. Jure (Kozik) and Lišnica.
Via Dinarica ascends from Klis to Mosor along the hiking trail leading to the peak of Debelo brdo, and then it proceeds to the mountain hut Lugarnica (1 hour and 30 minutes of hiking) and to the mountain lodge Umberto Girometta that offers a possibility of overnight stay (2 hours of hiking). On the next day, what follows is one hour of hiking to the mountain shelter Kontejner, and then three hours of hiking across Botajna and Tepla pola to the peak of Sv. Jure. From this peak, we can descend either to Dubrava or to Gata (2 hours and 30 minutes of hiking) and Omiš (additional 1 hour of hiking). Thanks to an abundant network of marked trails, Mosor offers quite diverse excursion options.
It is worth pointing out that karst terrain and exposure to sun and heat in the summer months make hiking in this area quite hard, so climbs should be planned in the morning hours, and long hiking campaigns should be avoided, especially around noon and in the early afternoon hours. Due to its karst character, entire Mosor is completely arid, with the exception of rare areas around isolated springs and ponds of water, so hikers should take sufficient drinking water with them.
