We were into the deepest cave in the world (and still unexplored), its called Vrelo, and its located in Republic of Macedonia, in the capital Skopje, in a canyon called Matka. Covering about 5,000 hectares and it’s one of the most popular places in Macedonia. A gorge in which a rich complex of mediaeval building survives, including churches, monasteries and remnants of a fortress (the mediaeval town of Matka). There are dozens of caves and large number of endemic plants and animals. You can find more information in the video. I hope that you will like it. Enjoy!
