Hainan Tropical Rainforest National Park is a broad concept, covering many scenic spots in Hainan. I went to several scenic spots such as Bawangling Yajia Scenic Area, Yinggeling, and Wuzhishan National Nature Reserve. The scenery is very beautiful, with waterfalls, gurgling streams, waves of forest waves, a wide variety of species, and a very high content of negative oxygen ions. It is a great place to relax and breathe deeply. It is very cost-effective and worth going.
