The only thing you really need to know about the Aggtelek Karst caves is that it is an absolutely fabulous place and a true masterwork of nature – just go there as soon as you can.

Once you’ve seen this place you feel like you want to return again and again and discover what’s behind the next cave and the next. The beauty of the shapes, forms and sizes of the stalactites and stalagmites is mind-blowing and it’s no wonder that many poets and painters have been inspired by its bizarre shapes and colours.

The caves are formed in 230 million year old Triassic limestone and about 2 million years ago, water started to get into the cracks, dissolving the limestone, widening the crevices and forming passages. Today there are over 1000 smaller and larger caves and you can visit the most spectacular ones on guided tours. I went for two tours and spent over four hours underground which was quite nice when the outside temperature was +35 and the caves holds a constant temperature of +9.

Aggtelek is not only caves but also a nature area and if you want to stay around for some time I can strongly recommend the Cseppkõ Hotel, run by the nice Mr Jorge, a former Hungarian border guard who knows the town and the area inside out.
