Located in the northeastern part of Qiongshan, the Mangrove Nature Preserve is only 27 kilometers from Haikou. The mangrove tree is a type of evergreen tree that grow in swamps and near beaches in tropical and subtropical zones. When the tide rises, the tree�s thick trunks become submerged under water. Only the green canopies bob up and down with the waves � a truly magnificent forest in the sea! To display its singular and distinctive beauty to more viewers, the government of Qiongshan city has invested a large sum of money in building a dock and purchasing more yachts.
