The Alay Valley is a broad, dry valley running east–west across most of southern Osh Province, Kyrgyzstan. It spreads over a length of 174 km east–west. The valley extends in north–south direction with varying width of 27 km in the west, 40 km - in the central part, and 3-7 km - in the east. The altitude of the valley ranges from 2,440 m near Karamyk to 3536 m at Toomurun Pass with an average altitude of about 3000 m. The area of the valley is 8400 km2. The north side is the Alay Mountains which slope down to the Ferghana Valley. The south side is the Trans-Alay Range along the Tajikistan border, with Lenin Peak,. The western 40 km or so is more hills than valley. On the east there is the low Tongmurun pass and then more valley leading to the Irkestamborder crossing to China. The eastern Kyzyl-Suu flows from the Tongmurun rise past Irkestam toward Kashgar. The western Kyzyl-Suu flows west from the Tongmurun rise and drains most of the valley, flowing on the north side. It exits through the Karamyk pass and a gorge into Tajikistan, where, under the name of the Vakhsh River it flows southwest into the Amu Darya. Highway A371 runs along the valley. The western pass to Tajikistan is closed to foreigners, but the eastern pass to China is open. A371 intersects the M41 highway north to Osh at Sary-Tash. To the south, M41 becomes very rough and leads to the 4,280m Kyzyl-Art pass to Murgab in Tajikistan, a route that requires considerable preparation and paperwork. The valley has a population of approximately 17,000 and is almost entirely Kyrgyz with a few pockets of Tajik population. One traveler says "with no jobs, a harsh winter climate, and poor conditions for agriculture, life is immensely tough here, and most of the adult male population have left to seek work elsewhere."
