Dali Erhai Lake Ecological Wetland is deduced from the water cycle formed by rainfall in Cangshan Mountain, and finally into Erhai Lake. It is mainly divided into four major fragments: "Rocky Beach Secret Land", "Dreaming Forest", "Playing in Yunxi Water", and "Exploring Erhai Lake". We can explore the various species of Cangshan Mountain and experience the water circulation system where the clouds and rains of Cangshan Mountain converge to the Shibaxi River and the Erhai Lake, allowing children to play with nature and play in the carefree world.
