Its cliffs are so close to each other that at some points they prevent the light from getting in. It is one of the biggest climbing challenges in this part of Europe. It was conquered in 1965 for the first time. Before that no one had ever seen in its entirety. There is a huge waterfall – Grabovine a couple hundred meters before the entrance. Mountaineers usually go to conquest it in late summer because water is not high. For this adventure you need full climbing equipment including diving suits. On the way through the three and a half kilometres long canyon you will come across waterfalls, straits, cascades, white water, narrow channels and a whole gallery of nature-made sculptures. The hardest challenge is the so-called Gate of Kamikazes – section about 80 meters long and in some parts only 25 centimetres wide. Those who decide to take this alpine adventure must know that once you get in and start going down the galleries, cascades and waterfalls you cannot go back - you have to go all the way to the end.
