Geographical locationHalong bay is in northeastern Vietnam, from E106°56' to E107°37' and from N20°43' to N21°09'. The bay stretches from Yên Hưng district, past Hạ Long city, Cẩm Phả town to Vân Đồn district, bordered on the south and southeast by the Gulf of Tonkin, on the north by China and on the west and southwest by Cát Bà island. The bay has a 120 kilometre long coastline and is approximately 1,553 square kilometres in size with 1969 islets. The area designated by UNESCO as the World Natural Heritage Site includes 434 km² with 775 islets, of which the core zone is delimited by 69 points: Đầu Gỗ island on the west, Ba Hầm lake on the south and Cống Tây island on the east. The protected area is from the Cái Dăm petrol store to Quang Hanh commune, Cẩm Phả town and the surrounding giants zone.ClimateThe bay is a sea islands in tropical wet with 2 seasons: hot and moist summer, dry and cold winter. Average temperature is from 15°C- 25°C. Annual rainfall is between 2000mm and 2200mm. Halong bay has the typical diurnal tide system (tide amplitude ranges from 3.5-4m). The salinity is from 31 to 34.5MT in dry season and lower in rainy season.HistorySoi Nhụ culture (16000- 5000 BCE)Located in Hạ Long and Bái Tử Long, there are symbolic archaeological sites such as Mê Cung and Thiên Long. There are mounds of remains of mountain shellfishes (Cyclophorus) and spring shellfishes (Melania), some fresh water mollusk and some rudimentary labour tools. The main living procedures of Soi Nhụ's habitants were catching shellfish and fish, collecting fruits and digging for bulbs and roots. Their living environment is coastal area unlike other Vietnamese cultures, for example those found in Hoà Bình, Bắc Sơn, etc.Cái Bèo culture (5000- 3000BCE)Located in Hạ Long and Cát Bà island, its habitants developed to the level of sea exploitation.History shows that Halong Bay has been the setting for local naval battles against Vietnam's coastal neighbours. 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 Dubhai Khan's fleet.During the Vietnam War, many of the channels between the islands were heavily mined by the navy of the United States, some of which pose a threat to shipping to this day.System of isles and cavesThien Cung grottoThien Cung grottoThe bay consists of a dense cluster of 1,969 limestone monolithic islands, each topped with thick jungle vegetation, which rise 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 Halong 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, Tuan Chau and Cat Ba, that have permanent inhabitants. Both of them have tourist facilities, including hotels and beaches. There are a number of wonderful 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 given names. Birds and animals including bantams, antelopes, monkeys, and iguanas also live on some of the islands.CivilizationFloating fishing villageFloating fishing villageA community of around 1600 people live on Halong bay in four fishing villages: Cửa Vạn, Ba Hang, Cống Tàu and Vông Viêng in Hùng Thắng commune, Hạ Long city. They live on floating houses and are sustained by capture fishing and marine aquaculture (cultivating marine biota).Originally in Ha Long Bay there was only one fishing village. Now there are about ten.Honourable nameIn 1962, Vietnam Ministry of Culture, Sport and Tourism arranged Halong Bay as National Renowned Lanscape Vestige.The bay was World's Natural Heritage listed by UNESCO at the 18th meeting of the Committee of the World Heritages of UNESCO (in Phuket, Thailand on December 17th, 1994) for its outstanding universal aesthetic value according to the criteria explained in the Operational Guidelines for the Implementation of the World Heritage Convention. On December 2nd, 2000 at the 24th meeting of Committee of the World Heritages in Cairns, Australia, Halong bay was admitted as a World Heritage Site for its outstanding geological and geomorphological value according to the criteria of that Convention.[1]Halong bay was introduced to nominate by New Open World Foundation as World's 7 Natural Wonder having result on 08/08/2008.[1]The Kissing RocksThe Kissing RocksGeology and geomorphologyHistory of tectonicsScientists say that Halong bay has experienced at least 500 million years in the various geological states of orogeny, marine transgression and marine regression. During the Ordovician and Silurian periods (500-410 million years ago), Halong bay was deep sea. During the Carboniferous and Permian periods (340-250 million years ago), Halong Bay was at shallow sea level.Karst geomorphology valueAs of simultaneous combination of factors like thick limestone layer, hot and moist climate and slow tectonic process in whole, Ha Long bay has had a complete karst evolutionary for 20 million years. There are many of karst topography kind in Ha Long such as karst field.BiodiversityHa Long Bay is host to two ecosystems: a tropical, moist, evergreen rainforest ecosystem and a marine & coastal ecosystem. The bay is home to seven endemic species.Endemic species * Livistona halongensis * Impatiens halongensis * Chirieta halongensis * Chirieta hiepii * Chirieta modesta * Paraboea halongensis * Alpinia calcicolaThe 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.EconomyTourismHa Long Bay is perhaps the most popular travel destination of the country. Foreigners and natives alike are attracted to its natural, universal appeal, not to mention the shopping and dining prospects located close by.CuisineSeafood in Ha Long is diversifying. Cuttle-fish- mực, oyester- hà, cyclinae- ngán, prawn (penaeidea- tôm he, panulirus- tôm hùm, parapenaeopsis- tôm sắt...), spunculoideas- sá sùng, nerita- ốc đĩa, charonia tritonis- ốc tù và, cà sáy... are popular in many famous delicious dishes.In literatureNguyễn Trãi wrote about Halong bay: "This wonder is ground raises up in the middle of the high sky". Xuân Diệu utter a praise: "Here is the unfinished works of the Beings...Here is the stones which the Giant played and threw away". Nguyên Ngọc summarized: "...to form this first- rate wonder, nature only uses: Stone and Water...There is just only two materials themselves chosen from as much as materials, in order to write, to draw, to sculpture, to create everything...It is quite possible that here is the image of the future world". Ho Chi Minh remarks: "It is the wonder that one cannot impart to others". Pham Van Dong embarrassed: "Is it one scenery or many seceneries? Is it the scenery in the world or somewhere?". Nguyễn Tuân recognized that:"Only mountains accept to be old, but Ha Long sea and wave is young for ever".Che Lan Vien sensed:"Hạ Long, Bái Tử Long- Dragons were hidden, only stones still remainOn the moonlight night, stones meditate as men..."Lord Trịnh Cương overflowed with emotion: "Mountains are glistend by water shadow, water spill all over the sky".Huy Cận was agitated: "Night breathes, stars wave Ha Long's water".
