Mount Mann – The Legendary Twin of Poetry Mountain

Ha Long – more than just its iconic island wonders, this destination also conceals a host of unique natural and cultural treasures that remain largely off the beaten path.
More Than Just Sea and Sky: Uncovering Ha Long's Hidden Gems
Ha Long City is renowned both nationally and internationally as a stunning semi-mountainous coastal area, encompassing a magnificent 'stone forest' on the water with 1,969 islands of myriad shapes and forms. While the iconic Fighting Cock Islet symbolizes Ha Long Bay, few are aware of the culturally rich twin mountains nestled within Ha Long City itself.


Bai Tho Mountain and Man Son Mountain are traditionally known as twin mountains, displaying strikingly similar geological features. Scientists suggest that both mountains were formed simultaneously during the second geological period.
These are Bai Tho Mountain and Man Son Mountain. Bai Tho Mountain is located across Bach Dang and Hong Gai wards, while Man Son Mountain is in Thong Nhat commune. One mountain stands on the north bank and the other on the south bank of Cua Luc Bay, separated by 12.6km. Both mountains share common characteristics: they are large, tall limestone peaks, isolated from neighboring mountain ranges, and possess quite similar geological features, minerals, and vegetation. According to scientists, these two mountains were formed at the same time during the second geological period.
Legend has it that in primeval times, the Jade Emperor sent a celestial being to patch up the tears between heaven and earth. This celestial being, known to mortals as a giant due to his immense size, carried stones to mend the sky. One day, as the giant shifted his burden, his carrying pole broke. One basket of stones fell to the edge of the sea, now known as Bai Tho Mountain, while the other fell to the edge of the forest at the foot of the Thien Son range – the 'five tigers sitting on the mountain' – in the Northeast region (five mountains over 1,000m high within the Dong Trieu arc), which is now called Man Mountain.
The twin mountains share an inseparable connection with the giant's footprints left on the earth. According to folklore, Cua Luc Bay, with its 17m depth and 18km2 surface area, is believed to be the giant's footprint, located between Bai Tho Mountain and Man Mountain. In Xich Tho village, Thong Nhat commune, bordering the northern shore of Cua Luc Bay, locals still recount stories of two giant footprints on a pine hill, which they refer to as the "giant's mountain" and the "giant's footprint." This depression, shaped like a human foot and about one &sagrave;o (360 sq m) in size, was cultivated by locals during the subsidy period and called the 'giant's field'.
Bai Tho Mountain

Bai Tho Mountain stands in the heart of Ha Long City. In 1992, it was recognized as a National Historical and Scenic Site.
Bai Tho Mountain, standing at 198.2m high with a base area of 22.9ha, was formerly known as Truyen Dang Mountain. In the past, fishermen and merchants referred to lighthouses as 'Truyen Dang,' now 'Hai Dang,' signifying beacons for vessels navigating the Northeast Sea. In 1468, King Le Thanh Tong, on a naval tour of the An Bang sea, arrived at the foot of Truyen Dang Mountain. There, amidst calm, clear waters, a grand, isolated mountain emerged with a spectacular landscape. Inspired by the scene, the King composed a poem and had it carved into the mountain face. Subsequently, 11 more poems by high-ranking officials from later feudal dynasties, as well as scholars and literati, were also carved onto the cliffs of Truyen Dang Mountain. Because the mountain bears many poems, with King Le Thanh Tong's being the most significant, locals eventually began calling it 'De Tho Mountain,' which gradually evolved into 'Bai Tho Mountain' (Poem Mountain).

King Le Thanh Tong's poem, comprising 56 Han characters, is carved into the rock face approximately 6m above the tide line.
King Le Thanh Tong's poem is carved into the southern slope of the mountain and is the oldest and most historically significant of all the poems. Comprising 56 Han characters, it is etched into a rectangular hollow on the rock face, about 6m above the high tide mark.
Following King Le Thanh Tong, many other poets also carved their verses into Truyen Dang Mountain. An Do Vuong Trinh Cuong's poem, carved in 1729, echoes King Le Thanh Tong's work. In 1910, Governor Nguyen Can of Quang Yen carved a poem; in the same year, the brothers Vu Tuan and Vu Dai, both magistrates, each carved two poems, and Vu Dai's wife, Mrs. Dao Thi Thoa, contributed one poem in Quoc Ngu (Vietnamese script). In 1929, Hong Lo Tu Khanh, Nguyen Van Ban, carved another poem; and in 1935, Governor Nguyen Van Dao of Quang Yen province carved a poem. There are two more poems carved into the rock on Truyen Dang Mountain from around the 1940s. The prefaces and content of these poems primarily celebrate natural beauty, the heroic spirit of the Tran Dynasty, and the prosperity of the Le Dynasty.
Bai Tho Mountain also serves as a historical site marking significant milestones for the military and people of Ha Long City during the struggles against French colonialism and American imperialism. On the night of April 30, 1930, patriotic miner Dao Van Tuat climbed Bai Tho Mountain and raised the Party flag on Mo Qua peak. On the morning of May 1, 1930, the red flag with a hammer and sickle soared proudly over Bai Tho Mountain in broad daylight, affirming the revolutionary spirit of the coal miners and striking fear into the French colonialists.

Cave No. 6, a historical relic, is currently managed by the Hong Gai Ward Youth Union.
During the resistance war against America, Bai Tho Mountain also bore many historical imprints. When US forces launched their first airstrike, a loudspeaker, transferred from a powerful cluster of speakers on the north bank of Hien Luong Bridge – the 17th parallel – was placed on Mo Qua peak to broadcast air raid warnings, along with a station to observe enemy aircraft from afar. The caves within the mountain vary in size, designated from Cave No. 1 to Cave No. 6. During wartime, these caves were used as shelters from bombs and bullets, postal communication stations, radio stations, and more. The spacious Cave No. 6 even housed the provincial hospital's emergency department.

The Duc Ong Tran Quoc Nghien Temple Festival has been restored and is held annually on April 29th and 30th, coinciding with Ha Long Tourism Week.
The mountain is home to numerous plant species, including beautiful flowers like orchids, Ficus microcarpa (rock fig), and bamboo, as well as wild golden monkeys. At the northern foot of Bai Tho Mountain lies Long Tien Pagoda, Ha Long City's largest and most beautiful pagoda; at the western foot stands a sacred temple dedicated to Hung Vuong Tran Quoc Nghien. The Bai Tho Mountain - Long Tien Pagoda relic complex was recognized as a National Historical and Scenic Site by the Ministry of Culture, Sports, and Tourism in 1992.
Man Mountain

Man Mountain is located in Da Trang village, Thong Nhat commune.
Man Mountain rises 381.8m high with a base area of 383ha, situated between two streams, Da Trang Stream and Luong Ky Stream, which converge before flowing into Cua Luc Bay. Man Mountain was formerly known as Ban Mountain, a beautiful and typical example of Ha Long City's terrestrial limestone mountain system.
Ancient legends and prophecies enshrine the saying, "Man Mountain anchors the sea, a myriad generations of emperors." According to page 406 of the Dong Khanh Du Dia Chi, compiled by the Nguyen Dynasty's National History Office between 1886-1888, the land of Hoanh Bo, now Ha Long City, boasted many beautiful stone mountains at the time, such as Ban Mountain, Truyen Dang Mountain, Hap Mountain, and Phuong Cac Mountain. However, only two mountains were renowned enough to be classified as 'Famous Mountains' then: Man Mountain and Truyen Dang Mountain. Historians state that Man Mountain once served as the main base for the Ly Dynasty army during the 11th-century resistance against the Song Dynasty. During the Tran Dynasty, in both resistance wars against the Yuan-Mongol invaders (1285, 1288), Man Mountain was chosen by Grand Prince Hung Dao Tran Quoc Tuan as the strategic reserve headquarters for the navy. After the victory at the Bach Dang Battle in 1288, King Tran Thanh Tong gathered his troops at Man Mountain, where he established an altar to offer sacrifices and report to the gods. Man Mountain is considered a vital 'mountain-river acupoint' in the Northeast region, a place of flourishing energy.

Bach Thach Linh Tu, the only temple in Vietnam dedicated to the Supreme Immortal of Taoism.
At the foot of Man Mountain lies an ancient sacred temple, affectionately known by locals as Da Trang Temple (White Stone Temple), but officially named Bach Thach Linh Tu. This temple is dedicated to the Supreme Immortal of Taoism. While many localities have built shrines or temples to venerate the Supreme Immortal, most are symbolic altars; Bach Thach Temple uniquely serves as the principal shrine, directly worshipping the Supreme Immortal of Taoism, making it a distinctive feature in Vietnam. In its inner sanctum, Bach Thach Linh Tu houses a monolithic white stone goddess statue, weighing over 1 ton, seated on a dragon throne in a serene posture, with a compassionate and peaceful expression. According to legend, this ancient deity guarded the White Jade Capital in heaven and Man Son, earning titles such as Heavenly Palace Supreme Immortal, Man Son Old Mother, and White Jade Lady. Reflecting the syncretism of the three religions (Buddhism, Taoism, Confucianism), Bach Thach Linh Tu also features altars for the Council of Four Palaces, the Jade Emperor, the Three Pure Ones, and a Buddhist shrine.

Mr. Trinh Van Khoa, a long-time resident of Da Trang village, shared that on Man Mountain there is a large, peculiar coffin-shaped stone block. The elders say it is a coffin from heaven, and its lid rests on Bai Tho Mountain.
On Man Mountain, at mid-slope, there are various strangely shaped natural rock formations. Some resemble large mushrooms, wider at the top and narrower at the bottom, locally called 'Hon Vanh Mu' (Hat Brim Islet). Others are box-shaped, with clean-cut edges and hollow interiors, which the elders claim are coffins, with their lids resting on Bai Tho Mountain (and indeed, Bai Tho Mountain also features such a rectangular stone slab, as the legend suggests). This peculiarity is linked to the proverb "an old snake sheds its skin, an old person slips into a coffin." To the east of the mountain lies a large rock cave called Dau But Cave (Buddha's Head Cave). Inside the cave are remnants of an ancient shrine; under a layer of faded moss on the cave ceiling, ancient Han characters, tentatively translated as 'Son Than Tu' (Mountain God Temple), are still visible, alongside fragments of ancient ritual artifacts. Deep within the cave, pristine stalactites shimmer when illuminated.
At the saddle-points halfway up the mountain, numerous depressions collect water, and crystal-clear water seeps from rock crevices. Locals call these 'Thien Be' (Heavenly Ponds) or 'Gieng Troi' (Heaven's Well). Thien Be holds water all four seasons; the water is icy cold in summer and warm in winter, with steam rising from the surface on early mornings, resembling boiling pots of water. This rising steam mingles with the night mist, gracefully swirling around the cat-eared rock formations, appearing like waves caressing an offshore sand dune. The water teems with freshwater shrimp, and many mountain crabs and forest snails thrive there. When disturbed, crabs as large as sea crabs raise their claws in defense, a charming sight that attests to the excellent living environment on Man Son Mountain.
It is highly probable that people once lived on Man Mountain. Some historical scholars suggest it was a site of Son Vi - Dong Son cultural sedimentation, with fossilized marine flora found in its caves. Folklore recounts that Man Mountain was once a refuge from invaders and the purges that often accompanied royal successions during feudal dynasties. This is evidenced by ancient Han characters on cave ceilings, fragments of ancient terracotta utensils, snail and clam shells, and groves of what appear to be cultivated mandarin orange trees. The mandarin trees of Man Mountain, growing vigorously amidst the rocks, yield abundant fruit. During the ripening season, many forest patches glow golden. In the past, shepherd children would climb to pick them, but today, the ripe mandarins fall to the ground, serving only as food for wild animals.
Man Mountain boasts a rich and diverse flora, very similar to Bai Tho Mountain, but being farther from urban areas, it has denser vegetation and more wildlife. The patches of soil interspersed among the rocks are home to many precious medicinal plants, terrestrial orchids, and wild animals such as antelopes, golden monkeys, monitor lizards, geckos, pheasants, and green peafowl. The Man Mountain relic complex was designated a National Historical and Scenic Site by the Ministry of Culture, Sports, and Tourism in 2014.
Cua Luc Bay
Cua Luc Bay, with its 18km2 water surface area and 17m depth, serves as the central connector between Ha Long City and Hoanh Bo district, following their merger into the unified Ha Long City. Cua Luc Bay shares a 'three-blessings' relationship with Man Mountain and Bai Tho Mountain. According to legend, Cua Luc Bay is the footprint of the giant who carried stones to mend the sky. When he shifted his burden, his pole broke; one basket of stones fell into the sea, becoming Bai Tho Mountain, and the other fell into the forest, becoming Man Mountain.

Cua Luc Bay was once an ancient port cluster, featuring Gạo Rang wharf and Dong wharf, with the Mac Dynasty Citadel situated on the shore.
There are differing opinions regarding Cua Luc Bay; some say it is the confluence of six rivers, while others assert it is entirely distinct from Luc Dau Giang in Hai Duong province. Cua Luc Bay, with mountain streams flowing directly into it, is free of alluvial deposits, resulting in crystal-clear forest water blending seamlessly with equally clear blue seawater. This is why a sea gate with clear blue water is called 'Cua Luc' (Luc meaning 'clear blue'). Today, Cua Luc Bay is an inlet with three water passages. The main passage is Cua Luc, flanked by two secondary passages: Hon Hai gate and Kenh Dong gate. Inside the bay lies an ancient port cluster, including Gạo Rang wharf and Dong wharf, located within the Van Yen, Tri Xuyen, and Bang Troi communes.
On July 26, 1884, Grand Mandarin Pham Than Duat, representing the Hue imperial court, signed an agreement leasing a coal mine to French capitalists for 100 years. When the French colonialists created their concession maps, the Bai Chay - Hon Gai area was an island, and boats would navigate from Hon Hai (Hong Hai ward) into Cua Luc Bay and out through Kenh Dong (Gieng Day ward). At that time, Bai Tho Mountain and Ba Deo Mountain were also islands. Hung Thang Island and Sa To Island only recently became connected to the mainland.
Cua Luc is mentioned in historical records concerning the classic naval battle of Van Don - Luc Thuy, where General Tran Khanh Du of the Tran Dynasty sank 600 Yuan-Mongol supply ships in the Northeast Sea in 1288. Furthermore, inscriptions from two poems carved on Bai Tho Mountain—one by Hong Lo Tu Khanh Nguyen Van Ban in 1929 titled “Boating on Luc Hai…” and another by Quang Yen Governor Nguyen Van Dao in 1935 titled “Arriving at Luc Hai for a Boat Ride…”—further reinforce the description of Cua Luc as a sea gate with clear blue waters.

Mr. Tran Van Nghi, a native of Xich Tho village, stated that a person with a body capable of carrying Bai Tho Mountain and Man Mountain would need feet as large as the entire Cua Luc Bay, though folklore suggests this is merely a myth.
Another legend states that Cua Luc Bay is the giant's footprint. It tells that as the giant, carrying stones to mend the sky, stepped across Cua Luc Bay and shifted his burden, his pole broke. One basket of stones fell into the sea, forming Bai Tho Mountain, and the other landed in the forest, becoming Man Mountain. The giant also left two footprints on a hill in Xich Tho village, each depression about one &sào; (360 sq m) in size. Locals who cultivated these low-lying areas called them the 'giant's field' and 'giant's hill.' However, Mr. Tran Van Nghi, a native of Xich Tho village who served as the head of the communal Culture Board for 10 years, commented that while the legend is interesting, a person with a body capable of carrying Bai Tho Mountain and Man Mountain would need feet as large as the entire Cua Luc Bay.
Bai Tho Mountain and Man Mountain, the twin peaks, along with Cua Luc Bay, form a 'three blessings' trio, intrinsically linked to the legends of the giant who carried stones to mend the sky, leaving his footprints on the hills. One tale tells of a mountain maiden working in a terraced field who accidentally stepped into a footprint and became pregnant, later giving birth to three snake deities, sons of the giant: Ong Coc (Shorty), Ong Dai (Long One), and Ong Loang (Spotted One), each with fascinating stories. Today, separate temples dedicated to these three snake deities are still maintained in the locality. Ong Coc is worshipped in Dong Hang, Ong Loang in Dong Cai, and Ong Dai in Da Trang.
Ha Long City has developed a plan for landscape and ecological tourism exploitation for Bai Tho Mountain and Man Mountain. Cua Luc Bay, according to the Ha Long City master plan approved by the Prime Minister for development until 2040, will see the central urban area of Quang Ninh province evolve into a model comprising five zones, with Cua Luc Bay serving as the central hub connecting socio-economic infrastructure. Currently, the cluster of ports within Cua Luc Bay, including Quang Ninh Port, CICT Container Port, B12 Petroleum Port, and Ha Khanh Coal Port, accounts for a significant proportion of Quang Ninh's revenue structure.

The giant's footprint on the hill in Xich Tho village, once as wide as a &sào; field, is now only the size of a buffalo wallow.
