Xuan Thuy Natural Wetland Reserve (Ramsar) is located in Nam Định Province, 150 km south-east from Hanoi. It is the largest coastal wetland ecosystem in the north of Vietnam and placed in the south of the Red River mouth. Aquaculture farms and some parts of mangrove forest cover the largest islet. The Park is a delta and estuary islands supporting coastal mangroves and the mud flat ecosystem in the Red River delta. The area includes land enclosed by sea dikes with fringing marshes. The area has a long history of wet rice cultivation as well as dike construction and land reclamation. This is a unique place and an unforgettable experience.
