Kopački Rit Nature Park

Fodor's choice

One of the largest remaining wetlands along the Danube, Kopački Rit Nature Park is a place of serene beauty. Embracing more than 74,100 acres north of the Drava, the park is covered with immense reed beds; willow, poplar, and oak forests; and crisscrossed by ridges, ponds, shallow lakes, and marshes. More than 300 bird species, hundreds of varieties of plants, and dozens of species of butterflies, mammals, and fish live here; it is also a breeding area for numerous endangered species, including the white-tailed sea eagle, the black stork, and the European otter.

The best times of year to visit are during the spring and autumn bird migrations, when there are often several thousand birds in the park. You can buy tickets at the welcome center, and then a boardwalk walking trail leads to the landing where boat excursions set out into the marshy heart of the park. There are different guided tours available; an early-morning small boat tour is usually your best bet. Call ahead to reserve and bring lots of mosquito repellent.

Another point of interest within the park is Tikveš Castle. Built in the 19th century by the Habsburg family and used as a hunting lodge by various monarchs and politicians over the years, including Tito, it was recently converted into a multimedia exhibition center documenting the history of the park and the region. To reach Kopački Rit from Osijek, cross the river and follow the signs from the municipality of Bilje. Tikveš Castle is a further 11 km (6 miles) away.
