The north is dominated by the eye-shaped Issyk-Kul lake, surrounded by the ridges of the Tian Shan mountain system: the Kyungey Ala-Too mountains to the north and the Terskey Alatau to the south (the 'sunny' and 'shady' Alatau, respectively). To the south is mountains and 'jailoos' (mountain meadows used for summer grazing). The highest peaks of the Tian Shan mountains, including Khan Tengri, are located in the easternmost part of the region.
