The mountain nodes Achik-Tash and Korumdy are the main and most popular areas for high-altitude mountaineering. Achik-Tash is located in the central highest part of the Zaalai (or Chon-Alaï) ridge. The mountain complex consists of powerful glaciers and peaks: Dzerzhinsky (6716 m), Kyzyl-Aga (6663 m), Estonia (6202 m). The highest and most popular point of the Achik-Tash mountain node is Lenin Peak, which is 7134 m high. From the edelweiss glade located in the Achik-Tash area, which serves as the starting point for all ascents to the seven-thousander, a wonderful panorama of the mountainous region opens up. Green alpine valleys are cut by ochre ribbons of rivers. In deep chasms are blue lakes, giant glaciers touched by cracks, and rivers flowing into the Alai Valley.
Korumdy Peak (6613 m) is located 60 km east of Achik-Tash. To the west, it is bordered by three unnamed peaks with heights of 6243 m, 6283 m, and 6080 m. One of the peaks with the beautiful name "Dawn of the East" (6349 m) is located right at the junction of the borders of Kyrgyzstan, Tajikistan, and China.
For a long time, this area was closed to visitors. This circumstance has likely allowed the region to retain a significant degree of obscurity. Several peaks over six thousand meters remain unconquered, which is a good factor for attracting climbers to this area. The entire territory is occupied by high-altitude, heavily dissected, and difficult-to-pass ridges. The crests of the ridges are narrow, rocky peaks are sharp, sometimes in the form of inaccessible summits. Glaciers descend in wide tongues, forming icefalls on steep sections.
