Dinara is a mountain located on the border of Bosnia and Herzegovina and Croatia. It has two major peaks: Troglav ("Threehead", 1913 m) and the eponymous Dinara (1831 m). The peak called Dinara is the highest peak of Croatia, is shaped like a human head made of stone, and also has a prominence of 728 m.
It is best known for the fact that its name is the base for the name of a large mountain chain called the Dinaric Alps or Dinarides. The Dinarides are known for being composed of karst — limestone rocks — as is the mountain that named them.
Dinara itself spans from the Derala mountain pass (965 m) in the northwest to the Privija pass (1230 m) which is 20 km to the southeast, where the Kamešnica Mountain begins. The Dinara Mountain is up to 10 km wide.
Dinara is located only a few dozen kilometers away from the Adriatic Sea, and is part of the Dalmatian hinterland, but the climate on Dinara is a much colder, mountain climate, making it one of the coldest places in Croatia with average temperatures between 2 and 4 °C at the peaks. The average precipitation is high, while the number of sunny hours per year ranges between 1,700 and 1,900.
One of the most fascinating massifs is on the southwestern slope. It is six kilometers long and up to 1700 meters high, providing an interesting landscape for the travelers on the roads in the valley below to view. The massif does not attract many climbers, but its Ošljak peak (1706 m) does.
