Northeast of the Danube Bend is Hungary's hilliest region with the country's highest mountain, Matra Hill rising to 998m (3,274 ft). It also contains the country's smallest village, where the first Hungarian-language bible was written, and the oldest railway from the 19th century. Here you can visit the preserved medieval village of Hollóko; see remnants of the country's Turkish heritage in Eger, also known for its regional wines and the region of the famous Tokaji aszú wines; and explore the 23km (14 mile) cave system in Aggtelek.
