River Valley in Kuapse Mammadov valley narrows sharply, forming a canyon. In the summertime when the water level is low it is quite passable. Colorful entwined with green ivy rocks of the Cretaceous sites linked up to a height of 3 meters, form the archway. From the ceiling hang thick limestone icicles. The walls are covered natёchnymi bizarre formations. But from the outside - the riot of nature, the birds sing. Above the cliffs, like a prison, huge towering oaks, chestnuts; murmuring streams.

Behind the tunnel the gorge suddenly widens and opens dazzling bright "White Hall". He developed eroding the power flow on the bend of the river. On one of the walls of the White Hall with a ten-altitude cascade breaks down a small stream - right tributary of the Kuapse. Because of its original form waterfall is named "Beard Mamed." In dry weather, "beard" is becoming rare, if not dry out. At the same creek, about fifty meters from the waterfall, there is an interesting handsome cascade, which falls under the stream of water gouged Grotto and the boiler. This is the "Bath Mamed." It is filled with clean, cold water. On the surrounding walls hang ferns.
