Biokovo (pronounced [bîɔkɔʋɔ]) is the second-highest mountain range in Croatia, located along the Dalmatian coast of the Adriatic Sea, between the rivers of Cetina and Neretva. Its highest peak is Sveti Jure (Saint George), at 1762 m.a.s.l.
The 196 km² of its area is protected as a nature park.
It is sometimes referenced to as Bijakova, especially among inhabitants of the eastern side of the mountain. When the weather is very clear, from the top of Biokovo it is possible to see Monte Gargano in Italy, which is 252 km (157 mi) away.
Biokovo is one in a line of Dinaric Alps stretching along the Dalmatian coast - northwest of it is Mosor and southeast of it are Sutvid and Rilić. In the east, the Šibenik runs in parallel.
To aid the hikers, there is the Biokovo Nature Park Visitor Center in downtown Makarska.
Biokovo is a part of the Dinaric Mountains and as such has a direction of NW-SE. The material in the lower parts towards the sea and on the opposite Zagorje side is mainly made up of Eocene Flysch sediments while the higher parts are shaped into carbonate sedimentary rocks.
The vegetation of the mountain Biokovo is very interesting and rich. It is an apparent mixture of different floral elements. There are mixed oldest Mediterranean, Boreal and Central European floral elements.
Based on previous research it can be concluded that the fauna of Biokovo is distinctive and varied although, unfortunately, still insufficiently explored. In the area of Biokovo there was a large number of endemic and tertiary relicts due to the fact that it is situated in a part of Europe which during the Tertiary was not largely affected by glaciation.
The climate on Biokovo is the result of latitude, its geographical position in the Dinaric mountains, geological structure, relief, altitude, exposure to the relief air circulation, vegetation cover and other factors that have a significant impact on mikroklimtske characteristics of this mountain.
