Excellent beaches on the island with its white sandy stretch as well as its warm, clear water are all ideal for your relaxation. Almost half of the Island was declared a national park, known as Cat Ba National Park, covering the tropical forest inland, the coastal mangrove swamps, and coral reefs offshore. The most highlighted beaches among others include Cat Co and Cat Dua. These are the large beaches separated by a small mountain range, an ideal place to swim as the water is warm and so clear that you can see the golden sand beneath.

Adjacent to the Cat Co Beach, there are also fascinating caves and grottoes waiting your discovery and exploration. If you would like to escape from the crowded beach, you have to hire a motor boat to the small islets where the calmer and cleaner beaches can be found; those are Cat Trai Gai, Duong Gianh and Hien Hao islets.

The Cat Ba Island is reachable by taking a ride of car or train from Hanoi to Haiphong for two hours, and then board on a high-speed vessel to get to the Island.
