Waters of the river, rushing down to form on the steep slope of the site falls cascade over a height of 50 m. In the lower slopes grow a variety of trees and shrubs: hornbeam, field maple, pear, oak, hazel, dogwood, blackthorn, dog rose. The upper slopes of the gorge almost vertically.

karstovedov many years of research found that the total length of all the known passages of the Kizil-Koba is more than 13 km, depth - 135 m. This is the largest in the country cave in the limestone. The first information on the Kizil-Koba appeared in print in 1843, has long been assumed that the length of the passages of the cave is about 2 km. However, once in 1957 to open a new move ("Shaman's throat"), were additionally examined and described more than 10 km of underground cavities - the grand halls and large galleries decorated with calcite wandering formations. Individual stalactites reach 5-8 m length here.
Special beauty openwork decoration extruded different so-called Indian and Chinese facilities. Glorious in Academic Hall, with an area of about 300 square meters, height of the arch - up to 8 m. The rooms are located further away, reaching 30-40 m height, 20-25 m wide and extend for tens of meters along the main direction of galleries. The old part of the lower cave, 180 meters from the entrance, at the end of the corridor Griboyedov (named after Griboyedov, who visited here in 1825), has long been known small underground lake and river. In the newly opened galleries and rooms flooded cavity stretch for hundreds of meters up to several lakes in the area of 500 square meters with a depth of 3 m or more. Groundwater reserves in the cave, depending on time of year range from 15 to 250 thousand cubic meters cubic meters
to Kizil-Koba can be rightly attributed the words of academician Fersman spoken to them about the Crimean caves at all:
. .. which is especially great in the caves, it is their dress ornaments, and sometimes lavish decorations - that of white, delicate patterns, and long columns, slender, as a young forest, and long, hanging down from the top of icicles, garlands, curtains. White, yellow, red mineral deposits cover the walls of their caves: in their bizarre forms lurk the mysterious wonders, resembling a shape of some giant frozen, the bones of giant dinosaurs .. .
Kizil-Koba and known as the archaeological monument: here the bones of cave bears and material traces of people's so-called kizilkobinskoy culture. At present, works are planned to make the Middle halls unique underground cave museum-reserve.
