The most attractive and most valuable parts of South Velebit are surely the impressive canyons of Velika Paklenica and Mala Paklenica. Velika Paklenica canyon is 14 km long and 500–800 m wide. In its narrowest part around the Bunkers, the canyon is only 50 m wide. Vertical cliffs rise above both sides of the canyon up to a height of over 700 m. The most attractive part is the area around the steep drop of the stream downstream from Anića luka, where steep cliffs rise directly above the stream, forming the narrowest part of the canyon between Anića luka and the parking lot. Mala Paklenica Canyon is of lesser dimension, and the torrent running through it is much less powerful. It is 12 km long and 400–500 wide. In its narrowest part, it is only 10 m wide, while the surrounding cliffs rise up to a height of 650 m.
