Cat Ba Island is located about 15 km south of Halong Bay. With an area of 354 km2, it is the largest island of the eponymous archipelago of Halong Bay.

Isolated by its island characteristics, there is no question of playing the Robinsons or on the contrary to go to a too famous seaside resort. Cat Ba is a little bit of everything, and this is what makes its charm.  You have to leave the noisy city of Hanoi, two hours by road or highway, a boat shuttle, a small winding road… and here we are in Cat Ba, the largest island of Halong Bay!

On the waterfront restaurants, hotels, small stores seem to contemplate the open sea and the harbor. Strolling from one to the other is a real pleasure. 

In addition to the magnificent sugar loaf landscape of Halong Bay, Cat Ba is also famous for its natural park, with beautiful beaches between small fishing villages. Cat Ba Island is in full tourist development but it still remains preserved. It is a relaxing seaside and natural stopover in your trip to Vietnam.

A place privileged by nature


The coastline is cut by rocky cliffs, embellished by small white sandy coves. The pure waters of the coastline are conducive to a dense marine fauna. Sea turtles, lobsters, corals, oysters and more than 200 species of fish, some of which are rare, live in the Cat Ba seas.

Crustaceans are not to be outdone with several hundred species of mollusks and arthropods. Cat Ba is the perfect place to enjoy the best fish and seafood dishes in Vietnam!

History and legend

The history of Cat Ba Island goes back 6000 years. The name Cat Ba means “the island of women” and as with everything in Vietnam, there are many interesting legends about it. It is said that many centuries ago, three women of the Tran dynasty were murdered. The bodies washed up on the shores of Cat Ba Island and were found by fishermen. The locals then built a temple for each woman and the island later became known as Cat Ba.

How to get to the island?

10 best sites and activities in Cat Ba


baie de lan ha

The bay of Lan HaThe best thing to do when visiting Cat Ba is to discover a wilder and off-the-beaten-track version of Halong Bay: Lan Ha Bay. Indeed, the surrounding waters belong to Lan Ha Bay, which has about 300 karst islands and limestone outcrops. The landscape of Lan Ha Bay is just as beautiful as Halong Bay, not to mention the added attraction of many white sandy beaches.

Since the bay is far from Halong City, few tourist boats venture here, which means Lan Ha Bay has a more secluded appeal. You can take a cruise with an overnight stay on an authentic junk. Or simply sail on a small fishing boat for a few hours.
