Located on the right bank of the Treska River, Vrelo Cave was listed as one of the top 77 natural sites in the world in the New7Wonders of Nature project.
Vrelo Cave has many stalactites including a large one in the middle of the cave known as the "Pine Cone" due to its shape. There are two lakes at the end of the cave, with one larger than the other. The smaller lake is 8 metres (26.2 feet) at its longest length and 14.92 metres (48.9 feet) in depth at its deepest point. The larger lake is 35 metres (114.8 feet) at its longest length, and 18 metres (59 feet) at its deepest point.
Though the exact depth of the cave is unknown, it is believed to be among the deepest in Europe and/or the world.
Matka is a natural canyon, which as a geographical relief is really special, and the speleological park is one of the most fascinating ones in the world. The beautiful Matka Canyon is only 15 km from Skopje. It covers 5,000 hectares of the beautiful Lake Matka, steep mountain slopes, exciting caves, and picturesque medieval monasteries. Thanks to its exceptionally good position near Skopje, the Matka Canyon attracts tourists from around the world.
There are ten caves and two steep rocks that are about 35 meters high and are a real challenge for mountaineers. Although in Matka there are so many caves of different sizes, the main tourist attraction that a small country like Macedonia could offer is precisely the Vrelo cave. The two cave lakes and the few beautiful and large cave galleries make Vrelo interesting for visitors. The true beauty can be captured from the inside, in the womb of the earth, where wonderful cave decorations are found. In the middle of the cave, there is a huge stalagmite in the form of a fir cone. The Vrelo Cave is located 50 meters above the lake. It is completely touristically arranged with trails that are intended for the movement of visitors. Vrelo is also known for being nominated for the selection of one of the seven world wonders and is assumed to be 330 feet deep, that is, it is the deepest underwater cave in the world.
