Aggtelek National Park is a large nature park in the north of Hungary, along the border with Slovakia. The park covers approximately 200 km². 

Aggtelek National Park combines beautiful nature above ground with breathtaking stalactite caves underground. 

There are 280 caves spread across the entire area. Each cave is different, both in size and the features of the cave. The caves are mostly made of limestone. 

The stalactite caves are listed as a UNESCO World Heritage site.

The above-ground terrain is also breathtaking and serves as a habitat for a variety of animal species. Some of the more promising sightings include the grey wolf, the Eurasian lynx, the red deer, and the wild boar. There are also many birds to admire, such as the Eastern imperial eagle, saker falcon, kingfisher, and many others.

There are many activities to do in Aggtelek National Park. These include cave tours in the stalactite caves (ranging from short to longer walks), various hiking trails above ground, bike tours through the park, horseback riding in the park, bird watching, and, of course, you can also explore on your own.

This cavity is a temporary source cave, formed by the karst water flowing down from the surface through the water wells from the area of Létrás-lápa and István-lápa, located on the eastern edge of the Great Plateau of the Old Bükk Mountains. The cave offers a unique sight with spectacular erosion shapes (such as mammoth teeth and mother-in-law's throat), along with beautiful stalactite formations, creating an unforgettable experience.
