Located 5 kilometres south of Duong Dong, the Coi Nguon Museum exhibits the private collections of former tour guide Huynh Phuoc Hue. The four floors of the museum building cover almost every aspect of life on the island, with ceramics, oysters, pearls, corals and even cuts from indigenous flora on display. In addition, there are examples of ancient pottery, old coins and banknotes, and a collection of folk art from across the years. The museum is open at all times.
