Nianbaoyu is a famous Shenshan Circle at the junction of Sichuan, Gansu and Qinghai provinces, which has become a geological park. It can not drive in the geopark. There are classic hiking routes. The total journey takes six days. It takes six days to buy a ticket and stay in it for one year. [Smile] But only a few campsites are in difficult conditions and only tents. We don't have so much time. It only takes six hours to walk to and from the Lady Devil Lake. The scenery is wonderful.
