Morii Waterfall is a green, humid nature stop near Ruili, close to China's borderlands with Myanmar. The waterfall and surrounding forest give the area a subtropical feel that contrasts with drier images of inland Yunnan.
It works best as part of a broader Ruili outing that includes border markets, temples, and Dai or Jingpo cultural landscapes. Go prepared for damp paths, and treat the waterfall as a scenic break from the bustle of the border city.
