In the 15th Century, Nguyen Trai (1380 – 1442), a great national poet visited Halong and spoke of:

“The way to Van Do has so many mountains
Nature has produced a wonder in the immense space
The vast blue sea looks like a grandiose mirror
Reflecting innumerable black mountains”.

(In 'Van Don' poem by Nguyen Trai, Complete Works, History Institution, Socio and Science Publishing House, HN 1976, pages 312 - 322).

King Le Thanh Tong (1442 – 1497) on a walking tour to An Bang (old name of Quang Ninh Province) was surprised by Ha Long’s beauty. He composed a poem and carved it on the wall of the mountain, praising the grace of Ha Long as follows:

Hundreds of water currents flow around mountains
Scattered islands look like a chessboard of sea joining the sky, both azure blue
Invaders are always expelled by Viet people
Stopping aggressive war and developing the country.

(Quoted from the poem “Bai tho de vach nui cua Thien nam dong chu” written by King Le Thanh Tong. The national center for Science, Society  and Humanity. Vietnamese language Institute. Socio and Science Publishing House,  Ha Noi, 1994.

Over 100 years ago, the French Journalist John Rey praised Ha Long: “ In the brilliant light of the tropical sun, the sea surface, dark and light, here and there in the shadow of limestone mountains, is really an indescribable, fanciful scene. Sunset looks like a flaring fire, throwing all the islands into a fairyland.”

In 1927, Emile Cordonnier wrote an article, “Halong Bay – a peaceful and beautiful place of Indochina” described it thus: “...Thousands of mountains rising from the water surface flaunt wonderful blocks of marble, images are merged together to create a marvelous picture. This scenery appears like a dream with tall pillars of rock and rugged islands rising from the clean waters of Halong Bay. The landscape here always keep calm and peaceful...". (According to Quangninh Newspaper, 15th January, 2000)
Famous contemporary poets went on a sightseeing tour to Halong, which kindled their poetic inspiration:

• Xuan Dieu, "the prince of Vietnamese poetry " expressed his great emotion:

" ... Here are laid half-made things
Mountains, islets, clouds and stones are disorderly scattered
In their game, the ancient giants threw the stones
From the trees is still smelt the after taste of ancient times..."

(The poem "Salute to Ha Long")

• The poet Che Lan Vien also described the marvelous scenery of Ha Long:

" No dragon shadow appears on Ha Long Bay
Wave embellished by the dark blue color passes hundreds of miles
The June sky makes the water twinkle likes silver lusters
Like seas smashing into the hull
Our boat passed by sunny thrones,
Vong Phu stone woman waits for her far-away husband,
As mountains have no human breath, birds come to build their nests,
To help stone mountains calm
Their sadness..."

(Passing through Ha Long)

Nowadays, many domestic and international politicians, poets, cultural celebrities and tourists make the same comment when they visit Halong Bay: “If you haven’t visited Ha Long Bay, you haven’t been to Viet Nam.”

The General Secretary of the Socialist Republic of Vietnam, Nong Duc Manh on his visit to Ha Long Bay on 29th October, 2001, wrote: "Ha Long Bay, a wonder bestowed by nature, a world heritage, an everlasting symbol of our lovely Vietnamese nation, is the pride of our people. All Vietnamese generations today and in the future must make the best effort to maintain, conserve and promote the great values of Ha Long Bay so that Ha Long Bay will be not only be a domestic tourist destination but also the rendezvous place for friends worldwide.”

In recent years, Halong Bay has been honored to welcome many international delegations, including the leaders of many countries of the world.
