** Region as classified by UNESCO.
Hạ Long Bay (literally: "Descending Dragon Bay"; Vietnamese: Vịnh Hạ Long) is a UNESCO
World Heritage Site, and a popular travel destination, located in Quảng Ninh province, Vietnam.
Administratively, the bay belongs to Hạ Long City, Cẩm Phả town, and part of Van Don district.
The bay features thousands of limestone karsts and isles in various sizes and shapes. Hạ Long
Bay is a center of a larger zone which includes Bái Tử Long bay to the northeast, and Cát Bà
islands to the southwest. These larger zones share similar geological, geographical,
geomorphological, climate, and cultural characters.
Hạ Long Bay has an area of around 1,553 km
2
, including 1,960 islets, most of which are
limestone. The core of the bay has an area of 334 km
2
with a high density of 775 islets.

In
1994, the core zone of Hạ Long Bay was listed by UNESCO as a World Heritage Site according
to criterion vii, and listed for a second time according to criterion viii.

There are remains from mounds of mountain shellfish (Cyclophorus), spring shellfish (Melania),
some fresh water mollusk and some rudimentary labour tools. The main way of life of Soi Nhụ's
inhabitants included catching fish and shellfish, collecting fruits and digging for bulbs and roots.
Their living environment was a coastal area unlike other Vietnamese cultures, for example, like
those found in Hoà Bình and Bắc Sơn.
[edit] Cái Bèo culture (5000- 3000 BC)
Located in Hạ Long and Cát Bà island, its inhabitants developed to the level of sea exploitation.
[edit] Feudal period
History shows that Hạ Long Bay was the setting for local naval battles against Vietnam's coastal
neighbors. On three occasions, in the labyrinth of channels in Bach Dang river near the islands,
the Vietnamese army stopped the Chinese from landing. In 1288, General Tran Hung Dao
stopped Mongol ships from sailing up the nearby Bach Dang River by placing steel-tipped
wooden stakes at high tide, sinking the Mongol Kublai Khan's fleet.
During the Vietnam War, many of the channels between the islands were heavily mined by the
United States navy, some of which pose a threat to shipping to this day.
[edit] System of isles and caves
Thien Cung grotto
The bay consists of a dense cluster of over 3,000 limestone monolithic islands (although locals
claim there are only 1,969 as this is the year of Ho Chi Minh's death), each topped with thick
jungle vegetation, rising spectacularly from the ocean. Several of the islands are hollow, with
enormous caves. Hang Đầu Gỗ (Wooden stakes cave) is the largest grotto in the Hạ Long area.
French tourists visited in the late 19th century, and named the cave Grotte des Merveilles. Its
three large chambers contain large numerous stalactites and stalagmites (as well as 19th century
French graffiti). There are two bigger islands, Tuần Châu and Cat Ba, that have permanent
inhabitants. Both of them have tourist facilities including hotels and beaches. There are a number
of beautiful beaches on the smaller islands.
Some of the islands support floating villages of fishermen, who ply the shallow waters for 200
species of fish and 450 different kinds of mollusks. Many of the islands have acquired their
names as a result of interpretation of their unusual shapes. Such names include Voi Islet
(elephant), Ga Choi Islet (fighting cock), and Mai Nha Islet (roof). 989 of the islands have been

geological states of orogeny, marine transgression and marine regression. During the Ordovician
and Silurian periods (500-410 million years ago), Hạ Long Bay was deep sea. During the
Carboniferous and Permian periods (340-250 million years ago), Hạ Long Bay was at shallow
sea level.
[edit] Karst geomorphology value
Due to a simultaneous combination of ideal factors such as thick, pale, grey, and strong
limestone layers, which are formed by fine-grained materials; hot and moist climate and slow
tectonic process as a whole; Hạ Long Bay has had a complete karst evolution for 20 million
years. There are many types of karst topography in the bay, such as karst field.
[edit] Timeline of geologic evolution
Some of the most remarkable geological events in Hạ Long Bay’s history in the last 1,000 years,
include the advance of the sea, the raising of the bay area, strong erosion that has formed coral,
and, pure blue and heavily salted water. This process of erosion by seawater has deeply engraved
the stone, contributing to its fantastic beauty. Present-day Hạ Long Bay is the result of this long
process of geological evolution that has been influenced by so many factors.
Due to all these factors, tourists visiting Hạ Long Bay are not only treated to one of the natural
wonders of the world, but also to a precious geological museum that has been naturally preserved
in the open air for the last 300 million years.
Date Geologic period Events
570,000,000-
500,000,000
BC
beginning of the
Cambrian era
The area, which now forms Hạ Long Bay, was basically
mainland, submitted to a process of rain erosion.
end of the Cambrian
period
The area was flooded, commencing the existence of Hạ
Long Bay.

and Permian periods
The formation of the limestone layer more than 1,000 m
thick. A shallow and warm sea reformed, which existed for
approximately 100 million years. It created two kinds of
limestone: the Cát Bà layer of the early Carboniferous
period (450 m thick); and the Quang Hanh layer of the
middle Carboniferous and the early Permian period (750
m thick). These two layers constitute the majority of the
islands of the Bay.
67,000,000 BC
end of the Cretaceous
period
Hạ Long Bay existed in the environment of a high
mountainous mainland due to the influence of strong
mountain-forming phases.
middle of the
Paleocene period
These motions remain continuous and stable, while strong
processes of erosion began, and after millions of years, a
form of semi-highland topography took shape. The
continuation of this erosion has progressively cut the
highlands into blocks with altitudes similar to today's
mountains

The many islands that dot the bay are home to a great many other species, including (but likely
not limited to): 477 magnoliales, 12 pteris, 20 salt marsh flora; and 4 amphibia, 10 reptilia, 40
aves, and 4 mammalia.
[edit] Cuisine
Seafood in Hạ Long is diversified. Cuttlefish- mực, oyster- hào, cyclinae- ngán, prawn
(penaeidea- tôm he, panulirus- tôm hùm, parapenaeopsis- tôm sắt ), sipunculoideas- sá sùng,
nerita- ốc đĩa, charonia tritonis- ốc tù và, and cà sáy, are among the varieties appearing in
popular local dishes.
[edit] Environmental damage
With an increasing tourist trade, mangroves and seagrass beds have been cleared and jetties and
wharves have been built for tourist boats.
Fuel and oil, along with tourist litter, have created pollution problems, which impact on both the
aquatic and terrestrial ecosystem of the islands. Human waste from portable toilets erected for
tourists, finds its way into the soil and water surrounding the islands, once more altering the
ecosystem functioning, through increased nutrient flow.
Game fishing, often near coral reefs are threatening many endangered species of fish. Often fish
caught in the bay are not consumed locally but exported to other markets around the region.
The delicate limestone cave ecosystems are diminishing as tourists visiting the caves break off
stalagmites and stalactites. Litter, including wine bottles, are dropped into cave streams. Visitors
exhale carbon dioxide, which has a deleterious effect on the caves. The mouths of some caves
have been widened to allow for tourist access. This increase in light has led to an imbalance in
the delicate links between flora and fauna, and a decrease in the humidity of the caves.

• It was featured in the programme The Hairy Bikers' Cookbook.
• It was featured in the penultimate episode of the UK television show "By Any Means" in
November 2008, when Charlie Boorman and his team were stranded in their boat.
• It was featured in a full length episode of the UK television show Top Gear, Series 12, on
28 December 2008.

• A background stage that looks very similar to Hạ Long as well as bearing a crate that has
the word "HALONG" written on it, is featured in Capcom's Street Fighter IV.
[edit] Tourist attraction
Hạ Long Bay is a famous tourist attraction in Vietnam. But several accidents happened in recent
years due to low safety standards. In February 17 2011, twelve died when their tourist boat sunk.
Most of them are foreign tourists, from Britain, Australia, France, Japan, USA, Russia, Sweden,
and Switzerland. Many tourists also died in similar accidents in 2002, 2006, and 2009. According
to BBC Vietnamese, some British and Australian tourists who visited Hạ Long Bay said that they
are "lucky to still be alive", and they are not surprised when accidents happen, as all tourist boats
are "very old"
