Halong Bay: UNESCO Islands, Legend & Geology of Vietnam’s Iconic Bay
By Jimmy Nguyen, Founder & Director of Asia Travel Expert Co., Ltd.Halong Bay (Vịnh Hạ Long, “Bay of the Descending Dragon”) is a seascape of nearly 2,000 limestone islands and islets in Quang Ninh province, north-east Vietnam, about 2.5 hours from Hanoi. A UNESCO World Heritage Site since 1994, it is famous for its karst towers, caves and floating-village heritage. You visit it by boat on official routes, with day fees of 200,000–250,000 VND per adult.
Status (checked October 2026): open as normal. Day and overnight cruises run every day on the official routes VHL1–VHL8; route fees are unchanged at 200,000–250,000 VND per adult for the classic day routes. Boats are suspended at short notice when storms or typhoon warnings are issued, mainly between June and October.
Why Halong Bay is worth seeing:
- World-class scenery: UNESCO calls it the most extensive and best-known example of marine-invaded tower karst on Earth.
- Double UNESCO recognition: listed for its natural beauty in 1994 and for its geology in 2000, then extended in 2023 to include the Cat Ba Archipelago.
- Spectacular caves: walk through Sung Sot, Thien Cung and Dau Go, or kayak through Luon Cave into a hidden lagoon.
- Island viewpoints and beaches: climb Ti Top Island for the classic panorama, or swim at Soi Sim.
- Living heritage: fishing-village culture at Cua Van and Vung Vieng, and prehistoric sites dating back about 18,000 years.

Is Halong Bay Worth Visiting?
Yes. Few landscapes anywhere match the scale of Halong Bay’s limestone seascape, and it is the one natural sight most visitors to northern Vietnam should not miss. It is busy, with hundreds of tourist boats on the classic routes, so the way you visit matters. An overnight cruise lets you see the bay at sunrise and sunset when the day boats have gone, while the neighbouring Lan Ha Bay and Bai Tu Long Bay feel quieter.
- Best for: first-time visitors to Vietnam, couples, families, photographers and anyone who enjoys kayaking and boat trips.
- Skip if: you dislike crowds and only have a few hours; in that case choose a quieter bay or a longer cruise rather than a rushed day trip.
- Short on time: a day cruise on route VHL2 (Sung Sot Cave, Ti Top Island, Luon Cave) shows the highlights in about 5–6 hours on the water.
The Legend of the Descending Dragon
According to Vietnamese legend, when the country was threatened by invaders from the sea, the gods sent a family of dragons to help. The dragons spat out jewels and jade, which turned into the countless islands of the bay and formed a stone wall that wrecked the enemy fleet. After the victory the dragons stayed on Earth: the mother dragon descended at Ha Long (“descending dragon”), and her children at Bai Tu Long, a name usually explained as “the young dragons paying homage”. The story explains why so many places in the bay carry dragon names.
Why Halong Bay Is a UNESCO World Heritage Site
UNESCO describes the Ha Long Bay – Cat Ba Archipelago as the most extensive and best-known example of marine-invaded tower karst in the world. The limestone formed over about 500 million years, and the karst landscape was shaped over roughly 20 million years in a hot, wet climate. When the sea rose after the last ice age, it flooded the valleys between the towers, leaving steep islands with caves, lagoons and wave-cut notches at their base. Read the official description on the UNESCO World Heritage Centre website.
| Year | Milestone |
|---|---|
| 1994 | Inscribed as a World Heritage Site for its outstanding natural beauty (criterion vii) |
| 2000 | Recognised again for its geological and geomorphological value (criterion viii) |
| 2012 | Confirmed as one of the New7Wonders of Nature |
| 2023 | Extended to include the Cat Ba Archipelago (Hai Phong): “Ha Long Bay – Cat Ba Archipelago”, 65,650 ha with 1,133 islands and a 34,140 ha buffer zone |
The 2023 extension made it Vietnam’s first natural World Heritage Site shared by two provinces, Quang Ninh and Hai Phong. That is why many cruises now combine Ha Long Bay with Cat Ba Island and Lan Ha Bay.
History of Halong Bay
Prehistoric cultures
People have lived around the bay for about 18,000 years. Archaeologists identify three prehistoric cultures here: Soi Nhu (about 18,000–7,000 BC), Cai Beo (about 7,000–5,000 BC) and the Ha Long culture (about 5,000–3,500 years ago), known for finely polished stone tools and pottery.
The Bach Dang victories
The Bach Dang River at the western edge of the bay saw Vietnam’s most famous naval victories. In 1288 General Tran Hung Dao destroyed a Mongol-Yuan fleet by planting iron-tipped wooden stakes in the riverbed, hidden by the high tide. Local tradition links the stakes to Dau Go Cave, the “Cave of Wooden Stakes”.
Fishing villages and the bay today
For generations, fishing families lived in floating houses sheltered among the islands. From 2014 more than 300 households were resettled on the mainland in Ha Phong, and the old village at Cua Van now tells their story through a floating cultural centre. In 2024 the bay welcomed about 3.2 million visitors, according to the Ha Long Bay Management Board. Learn more on Wikipedia.

Local Expert Tips for Halong Bay
These tips come from years of arranging Halong Bay tours for international travellers.
- Stay at least one night on board if you can; the bay is at its best at dawn, when the day boats have not yet arrived.
- Take travel insurance and keep your plans flexible from June to October: the port authority can stop all sailings when a storm approaches, and cruises then refund or rebook.
- Wear shoes with grip for the cave steps and the climb on Ti Top Island.
- Kayak in the morning or late afternoon, when the water is calm and the light is softer.
- Avoid Vietnamese public holidays and summer weekends if you prefer quieter caves.
- Read our Halong Bay travel tips and try the local squid cakes from our Halong food guide.
Halong Bay vs Lan Ha Bay
