More ways to explore the area's outdoor wonders
You step from the jeep into cold, thin air and the valley stretches open: a ribbon of river, a sprawl of spruce, and the jagged teeth of the Terskey Ala-Too pushing skyward. The trail climbs through meadows grazed by horses, threads over scree and boulder fields, and finally unveils Ala Kul’s turquoise bowl at 3,500 m—an alpine lake fed by glacier melt that seems to hold the mountains in suspension.
