At the site reserved as a climbing area, known as the Kuk Cyclamen sector, there is an epigraphic monument - a medieval inscription of duke Mastan Bubanjić carved into the rock.
The landscape of Drežanka Valley, including the inscription of Mastan Bubanjić, is inscribed into the List of National Monuments of Bosnia and Herzegovina by KONS.
With all its visible layers of rock, both at the bottom and at the top and above it, the Drežanka canyon is a considered by researchers an open-air paleontological museum, where it is possible to find fossils from the geological past spanning as much as 200 million years, from the Triassic, Jurassic, Cretaceous up to the upper Eocene.
The water appears occasionally, during heavy and prolonged rainfall, or snow melting season during spring.
It is actually a cavity (siphon) in the mountain depths where water collects throughout the year, so that during heavy rains or snow melting season, when it is completely filled, it empties as a waterfall.
