On the east side of the island there is a kilometres-beach with pure white sand. At the centre is a luxuriant benjamin fig tree; it was under this tree that President Ho Chi Minh stood and conversed with the population in 1962 during a visit. Formerly, under the feudal dynasties, this island zone contained a great quantity of rare and precious species of mother-of-pearls. At night, fluorescent pearls would light up the whole region. So there are several islands having name “Ngoc” such as Ngoc Vung (dazzling pearl), Minh Chau (Ngoc Chau)...

During the war against the US, the island belonged to a front of outward islands that served as protection for the eastern waterways.

It is also on the beach that many stone artefacts were discovered in 1937, opening a string of excavations and archaeological research aiming at providing some explanations of the mysteries of the ancient Halong culture.

Situated to the south of Ngoc Vung Island, some 34km southeast of the tourist boat wharf, this beach boasts clear waters all year round. Ngoc Vung is one of the offshore beach which is still kept pristine and unspoilt. Its 3-km sandy stretch sparkles in the sunlight.

Apart from swimming and sightseeing, visitors can also enjoy fresh delicious seafood supplied by local fishermen.
