The Chatkal valley follows the mountain chain of the same name, to the north-west of this chain, over a length of 160km before flowing into the Charvak dam in Uzbekistan. By road, there are only 2 accesses, either by Talas to the north and the Kara-Bura Ashuu pass located at 3302m. alt .; or from the south, via the Chapchyma Ashuu pass 2841m. alt. when arriving from the town of Kerben.
The capital is the village of Kanysh-Kyya, and the lower part of the valley is in the Besh-Aral nature reserve.
The Chatkal river is one of the most beautiful rivers for rafting, on the other hand tourist infrastructures are still very rare there.
On the other hand, the mineral resources are important there: lead, silver, zinc, antimony and building materials.
The natural parks located to the north and northwest of the valley benefit several species. The fauna is very particular and rich in the mountains. In the forests, among the wild fruit trees and bushes, live wild boars, foxes, bears, sometimes deer. The porcupine, the badger, the forest dormouse live in forest areas. The marten, sometimes the ermine and the weasel huddle near the rocks. High in the mountains graze Siberian goats, which are hunted by snow leopards. Groundhogs are everywhere. But above all there are a lot of birds here. The deciduous forests are rich in starlings, orioles, blackbirds, woodpeckers, goldfinches and nightingales. Magpies, coarse juniper, finches, mountain buntings live in juniper forests. On the rocks and the steep slopes nest doves, swifts and many birds of prey: vulture, kestrel, vulture, golden eagle and others. And stone placers are favorite places for partridges and grouse. Three types of fish are commonly found in mountain rivers: common marinka, Amu-Darya char, and Turkestan catfish.
