Cat Ba Island is one of the only populated islands in Ha Long Bay, with roughly 13,000 inhabitants living in six different communes, and 4,000 more inhabitants living on floating fishing villages off the coast.

Lakes, waterfalls and grottoes dot the spectacular limestone hills, the highest rising 331m above sea level. The island’s largest body of water is Ech Lake, (3 hectares). Almost all of the surface streams are seasonal. Most of the island’s rainwater flows into caves and follows underground streams to the sea, creating a shortage of fresh water during the dry season.Lan Ha Bay, encompassing the southern seas off Cat Ba, is dotted with hundreds of jungle-topped limestone islands with many deserted beaches.
