Danba is a small minority town in a narrow valley in Ganzi Autonomous Prefecture of Sichuan, surrounded by mountains where there are some incredibly beautiful villages. It's a good place to be as a base for exploring some of them. Danba is apparently the richest Tibetan town in Sichuan, and besides its beautiful villages it's famous all over the province for beautiful girls.
Most of the villages are within 10 km radius from Danba town. There are vans that transport passengers to each of these villages for 10 RMB each way. However, they don't have a schedule and might leave only when they are full. Hitchhiking is relatively easy, and if there are cars on these roads, they will most probably stop.
There's a bus station in the town center, and buses to Chengdu are frequent. Since the completion of the road to Siguniang Shan, it now takes about 8 hours to reach Chengdu.
