Jasenovac

One of the largest floodplains in the Danubian basin, this unique ecological and cultural landscape of 20,506 acres along the Sava River was accorded park status in 1990 and is included on UNESCO's roster of World Heritage sites. It has numerous rare and endangered plant and animal species, from white-tailed eagles and saker falcons to otters and the Danube salmon—and, as much in evidence in Cigoc, to storks. Its 4,858 acres of pastureland is also home to Croatia's highest concentration of indigenous breeds of livestock. Traditional village architecture—in particular, houses made of posavina oak—further contributes to the region's appeal. The park office provides park maps and other information on where to go and what to see; and, yes, issues park entrance passes (25 Kn). The easiest way to access the park is by car: while driving from Zagreb, exit the motorway at Popovaca and take the road to the right through the villages of Potok and Struzec toward Sisak.
