Kopački Rit (Kopački Tršćak, Hungarian: Kopácsi rét), is a nature park in eastern Croatia. It is located northwest of the confluence of the Drava and the Danube, situated at the border with Serbia. It comprises many backwaters and ponds along the Danube. It is one of the most important, largest and most attractive preserved intact wetlands in Europe.
A part of Kopački Rit has been designated as a special zoological reserve. Around 260 various bird species nest here (wild geese and ducks, great white egret, white stork, black stork, white-tailed eagle, crows, coots, gulls, terns, kingfishers, European green woodpecker, etc.), and there are many other species using this area as a temporary shelter on migration from the northern, cooler regions to the southern, warmer areas and vice versa.
There are 40-odd fish species (pike, ide, tench, bream, carp, catfish, pike-perch, perch, etc.). Several various mammal species inhabit the land (red deer, roe deer, wild boar, wild cat, pine marten, stone marten, weasel, sable, otter, etc.). Rich plant life, typical of wetlands, is found also in Kopački Rit.
The proximity of the big city of Osijek and its surroundings, as well as excellent communications (by road, railway, plane and ship) enable a high visiting rate. The beauty of "intact" nature, the multitude of waters, flora and fauna attract not only excursionists and visitors but also many experts and scientists from the whole of Europe. Guided tourist visits by panoramic ships, boats, team of horses or on foot are available. Some packages offer the possibility of photographing or video-recording animals, birds in particular.
Angling and hunting are allowed in certain parts of Kopački Rit, which are put under less strict protection.
The specialities of Kopački Rit (fish stew, grilled carp, venison, Belje wines, etc.) can be tasted in the nearby restaurant.
