Over millions of years, rain and seawater dissolved the limestone into steep towers called karsts. Many of the islands have hollow caves inside.

Ha Long Bay Quiz – Vietnam's Bay of Stone Towers

Ha Long Bay is one of the most famous natural wonders in Asia. Located in Quang Ninh province in northern Vietnam, on the Gulf of Tonkin, it is filled with nearly 2,000 limestone islands and islets that rise steeply from emerald water. Many are topped with jungle and hide caves, lagoons and small beaches. It is a UNESCO World Heritage Site.

The islands were formed over millions of years. Rain, rivers and waves slowly dissolved the limestone, creating tall towers called karsts, along with arches and caves. Sung Sot, Thien Cung and Dau Go are among the largest caves open to visitors, decorated with stalactites lit in many colors. Some islands have lakes inside, reached by kayak through low tunnels.

People have lived around the bay for thousands of years. Fishing families once lived in floating villages such as Cua Van, in houses built on rafts. Today, many have moved to the mainland, but some families still fish and farm pearls there. Ti Top Island, named after Soviet cosmonaut Gherman Titov, has a beach and a lookout over the bay.

Most visitors explore the bay on cruises in traditional junk boats, often staying overnight. Kayaking, swimming, cave visits and sunrise tai chi on deck are popular activities. Ha Long City has hotels, a cable car and a large Ferris wheel. Nearby, Lan Ha Bay and Bai Tu Long Bay offer similar scenery with fewer crowds.

Ha Long Bay is about two and a half hours by road from Hanoi. The bay is also famous in movies such as Kong: Skull Island.
