Osh, Lenin Peak & Arslanbob Walnut Forest Southern
Using Osh as a hub, head up to the Alay Valley to view Lenin Peak, then descend to the mountain village of Arslanbob.
This route covers three southern highlights: the ancient city of Osh, the Alay Valley and Lenin Peak Base Camp (at an altitude of over 3,000 meters), and the walnut forests of Arslanbob. It does not involve climbing, focusing instead on views from the Base Camp and Travelers Pass. With fewer tourists and striking mountain scenery, it is perfect for return visitors or those who prefer off-the-beaten-path routes. Accommodation is basic, and you must be comfortable staying in high-altitude yurt camps. This trip can be connected by flying from Bishkek to Osh.
Yurt camps at Base Camp are only open in summer, with Jul–Aug being the most reliable period. It turns cold after late September.
