Ak-Sai Valley

The Ak-Sai Valley is an extremely high-altitude, almost Arctic-like mountain basin in the Naryn region, spanning an immense elevation between 3,000 and 3,800 meters. This heavily isolated plain near the Chinese border is frequently referred to as the "Kyrgyz pole of cold," as brutal winter temperatures have been recorded plummeting to minus 53 degrees Celsius. Bounded to the south by the massive Kokshaal-Too mountain range, the stark landscape resembles a polar tundra far more than a traditional Central Asian steppe. The underlying ground is largely characterized by permafrost, which renders the growth of any trees entirely impossible. Despite these incredibly hostile living conditions, the Ak-Sai Valley is home to highly specialized and fascinating wildlife. It remains one of the last major refuges for the imposing Marco Polo sheep with their massive, spiraling horns, as well as Siberian ibex and the highly elusive snow leopards that prey upon them. Only the most resilient Kyrgyz herders dare to bring their hardy yaks into this severe but breathtakingly beautiful wilderness during the short, cool summers.
