Hutovo blato

Hutovo Blato (Mud) is a natural reserve and bird reserve located in the Herzegovina region. It is composed of marshlands, created by the underground aquifer system of the Krupa River.
It is fed from the limestone massif of Ostrvo that divides the Deransko Lake and Svitavsko Lake. 
The Hutovo blato reserve is on the list of  Bird Life International's Important Bird Areas.
It is the largest reserve of its kind in the region, in terms of size and diversity. It is home to over 240 species of migratory birds and dozens that make their permanent home in the sub-Mediterranean wetlands surrounding Deransko Lake.
During the migration season, tens of thousands of birds fill the lake and its surroundings.
This park offers photo safari, sports fishing, educational path etc.
