One of the most unspoilt stretches of the Black Körös River is in the Tiszántúl (literal meaning: beyond Tisza) region of Hungary. The Black Körös, which runs along the Mályvád forest, is one of Hungary's most unregulated rivers. The 20.5-kilometre long stretch of the river, between the Romanian border and the Szanazug confluence, has a winding route with numerous loops and curves. The winding river is surrounded by thousands of hectares of forests.
The enchanting Mályvád Forest is the second largest forest in the southern part of the Great Hungarian Plains and it boasts a lush vegetation. The ancient forest patches of Keszi, Bányarét, Törökerdő, Mályvád and Sitka still have the abandoned Körös riverbeds meandering through them. As a result of the decades-long efforts of the forest management to enhance water retention, a significant portion of the forest is rich in water again. The diverse habitats of the Mályvád Forest and the Black Körös River are home to many animal and plant species. The area has been an excellent hunting ground for centuries and its fallow deer population is famous all over the world. The Bányaréti ancient oak grove is a protected area and was once a resting area for animals of the forest. The remnants of the ancient oak forests of the Körös region, the English oaks and the European wild pear trees are of great genetic and scenic value. It is no wonder that the forest is a popular destination for nature lovers, photographers and people who enjoy hiking.
