Yongsheng County
An ancient frontier garrison county on Chenghai Lake, known for plateau lake scenery and spirulina production, with few tourists.
Yongsheng County lies in southeastern Lijiang, Yunnan, with the Jinsha River flowing along its west and south. Historically an important frontier garrison, its county seat retains some ancient architecture. The main attraction is Chenghai Lake, a plateau fault lake with blue water and a well-known source of natural spirulina; you can cycle or drive around the lake. Winter and spring are sunny with little rain and good for visiting. Most visitors come by road from Lijiang city, a drive of several hours; tourism is not heavily developed, so it remains quiet.
