Cong Do Island is located in Bai Tu Long Bay region, south-east of Halong Bay and around 25 km from Bai Chay Port. Covering an area of 23 363 km2 and home to a 172 metre high mountain, Cong Do Island is well-known for its pristine, natural charm.
As well as diverse vegetation, a natural salt lake, which is the habitat of many species of marine life such as shrimp, crab, fish, squid, seaweed and algae, there is also a coral reef on the south-west of the island. With its myriad of vibrant colours, the 700 metre long, 300 metre wide reef supports the marine ecosystem to be perfect for diving, especially when the future plans for this area include a scuba diving zone.
For history buffs, the south-east of the island still has remnants of the old Van Don trading port, proof that Cong Do Island formerly held a key position in Vietnam’s commerce and trade with foreign countries.
