Bai Tho Mountain, or Poem Mountain, is a 168-meter limestone peak in the middle of Ha Long City, on the northern shore of Halong Bay. It is named after a poem a Vietnamese king had carved into its cliff in 1468. The climb has been officially closed since November 2017, so this Bai Tho Mountain Halong Bay guide covers the history, the current access rules and what visitors can still see around its base.
Bai Tho Mountain Halong Bay overview
Bai Tho Mountain is a historic limestone peak in the center of Ha Long City, known for the royal poems carved into its cliff, its use as a military lookout and its position directly above the bay. The Vietnamese name Nui Bai Tho translates as Poem Mountain.

History and the origin of the name
The mountain was called Truyen Dang Son long before it had a poem on it. The name means the mountain that passes on the light, and it describes what the peak was used for: guards at the top lit fires to warn the capital that enemy ships had entered the coastal waters.
The present name dates from 1468, when King Le Thanh Tong stopped here on a boat trip through the bay, wrote a poem praising the scenery and had it carved into the southern cliff. Lord Trinh Cuong read that poem in 1729 and had a second one carved nearby, which is how Bai Tho Poem Mountain came to hold poems from two royal courts more than 250 years apart.
Location of Bai Tho Mountain
The mountain is located in Hong Gai Ward, in the old center of Ha Long City on the Hon Gai side, with the former climbing entrance on Hang Noi Street. It is close enough to the water that boats leaving the bay pass directly beneath it.
That central position is what makes the site easy to include in a city itinerary even with the summit closed. The cultural sites at the foot of the mountain are within walking distance of each other, and the restaurants and markets of Hon Gai are a few streets away.
Current access status
Anyone searching for Bai Tho Mountain closed will find the same answer in 2026: the climb is not open. Quang Ninh authorities shut the route in November 2017 after a forest fire on the mountain caused landslides, locking the main gate and fencing the entrance. After a fatal fall on the closed route, the Hong Gai Ward People's Committee again asked visitors not to climb.
Things to do at Bai Tho Mountain
The peak of Bai Tho Mountain
The Bai Tho Mountain hike was for years a free viewpoint used by many visitors to Ha Long, with a flagpole at the top and a clear view across the limestone islands, the harbor and the city. Older blogs still describe the route in detail, which is why the closure catches so many travelers by surprise.
Until the route reopens with official supervision, the mountain is something to look at rather than climb. It photographs well from the Hon Gai waterfront, from the bridge and from the deck of a boat leaving the bay, and these angles show how steep the cliff is.
Visiting Long Tien Pagoda
Long Tien Pagoda is located at the foot of the mountain and is one of the main Buddhist pagodas in Ha Long City. Its courtyard, curved roofs and altars are a quiet contrast with the cruise terminals and beaches a few kilometers west.
The pagoda is busiest during the lunar new year and on festival days, when local families come to make offerings. Visitors are welcome outside those periods too, as long as they dress modestly and keep noise down inside the halls.
Worshipping at Duc Ong Temple
Duc Ong Temple, also called Tran Quoc Nghien Temple, is located nearby and honors Tran Quoc Nghien, a general of the Tran dynasty and a son of Tran Hung Dao. The temple links this area to the coastal defense history that gave the mountain its original signal-fire role.
The temple is small and takes only a short visit, but seeing it together with the pagoda and the carved cliff shows more clearly why this corner of Ha Long City was important long before the first cruise boat arrived.
How to get to Bai Tho Mountain
Travelers asking how to get to Bai Tho Mountain should aim for Hong Gai Ward, the old center of Ha Long City east of Bai Chay Bridge. From the hotels and boat harbor around Bai Chay it is a short taxi or Grab ride across the bridge, usually 10 to 15 minutes depending on traffic. The hotel and beach area on the other side of the bridge is Bai Chay Ha Long.
From the capital, the road journey takes around 2.5 to 3 hours by limousine bus, private car or shuttle, and the options are compared under Hanoi to Halong Bay. Reaching the base of the mountain is easy. Reaching the top is a different matter, and there is currently no authorized route up.
The view of the cliff from the waterfront depends on the haze, which is thickest in late winter and clearest in autumn. The Halong Bay weather by month shows when visibility is usually best.
Planning a visit to Bai Tho Mountain
Bai Tho Mountain fits into a half day on the Hon Gai side of the city. A one-day visit to Ha Long can combine the waterfront, Long Tien Pagoda and the Hon Gai market with a Halong Bay day cruise from the Bai Chay side, since the two areas are 10 to 15 minutes apart by taxi.
