The “Drava-Mura” Regional Park is the largest single protected area in the region. It stretches from the Croatian-Slovenian border to the Danube through five Croatian counties. The gravel and sand banks of the Drava are one of the last breeding grounds for the endangered little tern in Continental Europe. Several thousands of pairs of sand martin breed in the steep banks. The surrounding settlements are home to a rich culture, such as the village of Hlebine at the Drava, which became world famous for the origin of Croatian Naive Art.
