=== Into China ===
From Sary-Tash, just walk to the road leading to Irkeshtam and hitch. Most trucks will pick up hitchhikers, but
most of them will also demand money. The usual fare seems to be 300 som or US5–10.
The border seems to close at 2 pm kyrgyz time. If you arrive too late and it's too cold for camping, you can stay with the locals in Irkeshtam for 100 Som.
