The canyon, which is located between Trebče and Zagaj, is about 3km long and is famous as one of the best-preserved river canyons in Eastern Slovenia. More than 200 million years ago, the river here cut its river bed, which is still surrounded today by steep, wooded, and rocky slopes. Between Rebrija and Tisovec it is so narrow, it is almost impassable. The canyon impresses with its intactness, as here many protected species of animals and plants find suitable and valuable shelter, like chamois, birds of prey, wild boar, dragonflies, trout, crustaceans, Carniola lilies, wall pepper, Jovibarba – “beard of Jupiter”, barbed sheds. The canyon is extremely landscape varied and picturesque.

Because of their intactness, various plants and animals find their shelter here
