Aggtelek National Park

Altitude: 300-600m (930-1850ft)

Covering an area of 20,000ha (78 sq.mi) on the Slovak-Hungarian border, some 70km (44mi) north of Miskolc, lies Aggtelek National Park, with some unique flora and fauna and several hundred limestone caves and underground passages. A network of signposted paths and roads attract many walkers to this nature reserve. The chief attraction is the Baradla Cave; it is 25km (16mi) long (of which 7km (4mi) lie in Slovak territory, where it is known as the Domica Cave), making it one of the largest and most impressive dripstone caves anywhere in Europe.
