Fast facts

Cong Do (Cống Đỏ) or "Red Drainage" in English, is a small island at approximately 24 square kilometers in size. Just like so many of the other islands around Halong Bay, Cong Do is very diverse in its flora and fauna. In the lagoons that are found around the island, there’s an abundance of sea life in the form of squid, crab, various fish, and underwater vegetation.
