Ha Long Bay

UNESCO World Heritage Site, first inscribed in 1994. Since 2023 it has been listed as Ha Long Bay – Cat Ba Archipelago. The heritage property covers 65,650 ha and 1,133 islands and islets in Quang Ninh Province and Hai Phong City. The bay lies about 164 km southeast of Hanoi, roughly 2.5 hours by expressway. Visits follow numbered official boat routes. Day sightseeing fees run from 70,000 to 600,000 VND per person, depending on the route. The name Ha Long means 'descending dragon'.

Ha Long Bay lies on the north-western edge of the Gulf of Tonkin in Quang Ninh Province, about 164 km southeast of Hanoi. Hundreds of steep limestone pillars and forested islets rise straight out of green water, and many of them are hollowed by caves and grottoes. UNESCO calls the area the largest and best-known example in the world of tower karst that has been flooded by the sea.

Since a boundary extension in 2023, the World Heritage property has been listed as Ha Long Bay – Cat Ba Archipelago. It covers 65,650 hectares and 1,133 islands and islets in Quang Ninh Province and Hai Phong City. Geologists value the bay for two landforms: fengcong, which are clusters of cone-shaped peaks, and fenglin, which are isolated towers. They also study its enclosed lakes, which sit in drowned sinkholes, and its three main types of cave. The protected area is home to rare wildlife, including the critically endangered Cat Ba langur and the Cat Ba tiger gecko.

Most visitors explore the bay by boat. The Ha Long Bay Management Board runs a set of numbered sightseeing routes from the cruise ports. Some are short day trips to caves such as Thien Cung, Dau Go and Sung Sot. Others are one- or two-night cruises with stops for kayaking, swimming and visits to the bay's floating fishing communities.

When to go: Vietnam's national tourism board describes September to November as cool with generally clear skies, which makes it a good time for views across the bay. April and May bring sunshine and a cooling breeze. From December to March, mist often covers the karsts. This makes for atmospheric photos but can limit visibility. June to August is the monsoon season, so the weather is less predictable and cruise plans may change.

Getting there: Ha Long Bay is about 164 km southeast of Hanoi, and the expressway transfer takes roughly two and a half hours. Most travellers book a cruise package that includes return transport from Hanoi. Independent travellers can take a bus to Ha Long City or Hai Phong and then a taxi to the cruise port. Seaplane charters fly direct from Noi Bai International Airport in about 45 minutes.

People have lived among these islands since prehistoric times. Archaeologists working in the bay's caves and along its shores have found a series of early coastal cultures. The first is the Soi Nhu culture, whose people collected shellfish, wild fruit and roots. The Cai Beo culture came next and shows a growing reliance on the sea. The later Ha Long culture is named after the bay itself. Britannica also mentions stone tools from the Hoabinhian tradition of about 10,000 years ago, which shows how long the coast has supported human life.

The channels around the bay also played a part in Vietnam's military history. In 1288, General Tran Hung Dao stopped a Mongol fleet sent by Kublai Khan on the nearby Bach Dang River. His troops drove wooden stakes with metal tips into the riverbed, and the invading ships were wrecked on them. Around the 15th century, the scholar and statesman Nguyen Trai praised the scenery in his poetry. According to Britannica, Chinese and Vietnamese pirates were still using the maze of islands as a hiding place in the 19th century.

The name 'Ha Long' means 'descending dragon'. Older Vietnamese records used other names for the area, including An Bang, Luc Thuy and Van Don. The name Ha Long first appeared on French nautical charts in the late 19th century. A popular legend says that dragons sent to protect the young nation spat out jewels, and the jewels became islands that blocked enemy ships. French visitors at that time called Dau Go cave the 'Grotte des Merveilles' ('Cave of Wonders'). In June 1948, the bay was the setting for the Ha Long Bay Agreements between France and Vietnam's provisional central government.

Official protection began in 1962, when the bay was listed as a national scenic site. In 2009 it became a Special National Monument. UNESCO added Ha Long Bay to the World Heritage List in 1994 for its scenery, and recognised it again in 2000 for its geological value. Nearby, Cat Ba became a national park in 1986 and a UNESCO Biosphere Reserve in 2004. In 2023, a major boundary change added the Cat Ba Archipelago to the heritage property. Quang Ninh Province and Hai Phong City now manage it together. Rising visitor numbers remain one of their main conservation challenges.
