On the south-east side of
Halong Bay, about 25 km
from Bai Chay Wharf, Cong Do is in
Bai Tu Long Bay
in the region which recognised as the World
Heritage. It has an area of 23,363 sq. m, and its
mountain reaches a peak of 172 m. The island
features many lagoons, which are the residence of
numerous species of sea-life, such as shrimp, crab,
fish, squid and aquatic plants. On the south-west
side of the island, there is a wide coral reef
displaying a myriad of colours.
Coral reef ecosystem is more than 700 m long and 300
m wide. It is preserved almost undamaged. In the
future, there are plans for the development of a
zone for scuba-diving. On the south-east side of the
island, vestiges of the ancient commercial port of
Van Don were discovered. This confirms beliefs that
Cong Do Island once held an important position in
terms of foreign trade.d. |
