We went to the Tibetan areas of Gansu and Sichuan with a travel agency called Nomad Travel, based in Xiahe. It is owned by a Dutch woman who lives in Xiahe with her Tibetan husband Wandhikhar. We started off in Lanzhou and went overland to Chengdu via Xiahe, Langmusi and Songpan. It was absolutely delightful! The people in this area are so friendly and warm, it really touches your heart. Our tour was guided by Wandhikhar, a Tibetan man from Xiahe, who was so helpful and patient in explaining the Tibetan culture to us. We visited a nomad tent on the grasslands and he showed us how to make tsampa, the staple food for Tibetans. In Xiahe and Langmusi there are wonderful Monasteries, where we got lots of info on Tibetan buddhism. I was all so wonderful, nice people, nice scenery. In Songpan you can do a horse trek through the mountains, very nice, but you do have to walk sometimes because the slopes are steep. Still a good experience.
