Nature Park Blidinje is located in Hercegovina, in the northern zone of the Dinarides, northwest to Mostar, on the right bank of the Neretva. To the east it borders with the Neretva gorge, on the north side by the canyon of river Doljanka, and on the southern by the canyon of the river Drežanka. The park covers an area of 358 km2, and includes the area of mountain ranges of Čvrsnica, Čabulje and Vrana.
Due to its favorable geomorphologic characteristics and impressive landscapes, Blidinje was declared the Nature Park in 1995.
The main motives for the establishment of NP Blidinje are found in a variety of endemic plants, the diversity of the animal life that inhabits the beautiful forests, abrupt cliffs, deep abysses, living freely to develop by the laws of nature, far from the influence of man.
Natural Park Blidinje covers most of the massifs: Čvrsnica mountains, Vran mountains, valleys Dugo polje (long field) and far western parts of the massif Čabulje. This is an area of high mountain features of 1000 m to 2228 m. Close to 40% of the Park area is covered with forest.
The central part of the park is dominated by the beautiful, vast expanse – Dugo polje (long field), a typical closed karst depression. It has a tray shape, it is about 12 kilometres long, wide from 2 to 3 km, and is located at an altitude of 1250 m. Blidinje Nature Park is named after the Blidinje Lake which is located in the bottom of Dugo polje (long field) at an altitude of 1184 m. The average area of the lake is 3.2 square kilometers with a relatively shallow depth. The water in the lake comes primarily from the surrounding.
