Blidinje Park was named after the Blidinje Lake nested at the base of the Long Plain (Dugo polje) at 1,184 meters above the sea level. The lake spans 6 square kilometers. Majority of the water flowing into the lake comes from snowmelt that drains from the mountains Vrana and Cvrsnica (Čvrsnica).
During summer months the water levels drop, flowing through the porous bottom of the lake. Region’s natural distinctiveness abounds in opportunities for exploring some of many endemic plant and animal species, enjoying plentiful springs of sparkling clear water, and archeological sites.
The Lake Blidinje belongs to Posusje and Tomislavgrad municipalities in the south of Bosnia and Herzegovina. On March 30, 1995 it was declared a national park.
