One of the most beautiful caves of its kind, it's the most popular one. Riding in a boat in the cave is possible. The bigger part of this 25-km long cave belongs into Aggtelek's Baradla cave in Hungary. The cave shows signs of settlements 4,000 years ago.
The Domica cave is a karst cave situated on the south-western border of the Silicka planina Plateau 10 km (6.2 mi) south-east of Plesivec in the Rožňava District of the Košice Region in southern Slovakia. In combination with the Baradla cave, it makes up the most significant section of the Aggtelek Karst and Slovak Karst cross-border cave network that continues into the Aggtelek National Park in Hungary. The cave is well known for its complex structure and high density of speleothems.
