It is a protected oasis, 12 km long and about 400 metres wide, consisting of rock walls worn away by the erosion that water has caused over millennia. The cliffs of the ravine are more than 200 metres high and feature whitish limestone walls with cavities and ledges suspended in the void.
The ravine is home to many plant species, including wild orchids and Euphorbia dendroides, but also to very interesting fauna, such as the Egyptian vulture, the cricket hawk and the black stork, as well as mammals such as porcupines, badgers, foxes, weasels, wild boar, amphibians and reptiles such as the kotschy gecko and the leopard coluber.
