There are three waterfalls in the picturesque canyon of Dushan dere. The canyon has an overall length of 250 metres.Impressive cliffs with different shapes are towering above it. When viewed from different angles, they resemble human and animal figures.
There is a huge rock, whose height is over forty feet, “anchored” in a weird way on the right bank of the river. A big part of it almost floats in the air and it looks as if it is just about to fall down. A similar rock can be seen on the opposite bank. An overgrown path goes up to its heart. Flat riverbeds, where water playfully rushes, alternate with deep rock-hewn channels, so narrow in places that one can jump over them. The same cannot be said about the several deep pools with steep cliffs, where, if you happen to fall, you cannot get out without the aid of a rope. If you continue down the way, you will pass by a rock in which more than a hundred niches have been carved. If you follow the windings of the rock, you can go up a plateau region, dotted with rock cuts. However, the most interesting thing here is the "face". It is situated on an almost horizontal rock edge and strikingly resembles a human face.
