1. Pu Sam Cáp Cave
The Pu Sam Cáp cave complex is part of the Pu Sam Cáp mountain range, located at an altitude of 1300m to 1700m above sea level. The caves lie along Provincial Road 129, which connects Lai Châu City with Sin Ho District, about 5 km from the city center. The range stretches from northwest to southeast, marking the natural border between Lai Châu City, Tam Đường District, and Sin Ho District. This limestone mountain range, shaped by tectonic processes, features a southern slope that is gentle and a northern slope that is steep and rugged.
The Pu Sam Cáp cave system is a stunning natural creation, with over 10 caves of various sizes. Among them, three major caves—Thien Mon Cave, Thien Duong Cave, and Thuy Tinh Cave—are key highlights of the area and are currently being developed for tourism. Thanks to its unique natural beauty and ongoing investments, the Pu Sam Cáp cave complex is a promising tourist destination. Visitors to the caves can marvel at the breathtaking landscapes and immerse themselves in the majestic yet serene surroundings.
In November 2011, this scenic area was officially designated as a National Heritage Site by the Ministry of Culture, Sports, and Tourism.


2. Nậm Tun Archaeological Site
The Nậm Tun archaeological site, located in Mường So Commune, Phong Thổ District, Lai Châu Province, has been officially recognized as a National Heritage Site by the Ministry of Culture, Sports, and Tourism.
Discovered in 1973, the Nậm Tun site features a cultural layer that is 1.8 meters thick and contains two distinct layers. The upper layer includes polished stone axes, ceramics, and three tombs (preserving the remains), representing the later stages of the Neolithic period. The lower layer reveals nearly 200 rough-hewn stone tools, over 700 flint fragments, and two tombs, representing the late Paleolithic period. This site is one of the oldest cave settlements in the Northwest, associated with the Sơn Vi culture.
The Nậm Tun cave site was a settlement, burial, and tool-making area for two successive human groups, each corresponding to different stages of the Stone Age: the earlier and later Neolithic periods. It contains five ancient tombs and numerous artifacts, including bone needles, the first of their kind discovered in Vietnam.
This archaeological site holds great national significance. Its recognition as a National Heritage Site not only enables preservation and restoration efforts but also serves as a source of national pride, reinforcing the sovereignty of the country.


3. Cầu Mây Waterfall & Heaven Gate
Ô Quy Hồ Pass, also known as Mây Pass or Hoàng Liên Pass, crosses the Hoàng Liên mountain range at an altitude of nearly 2,000 meters, often covered in clouds year-round.
Local legend speaks of a bird with a haunting call, linked to a tragic love story. Over time, the call 'Ô Quy Hồ' became the name of the pass. The pass is situated along National Highway 4D, with two-thirds of its length in Tam Đường District, Lai Châu, and the remaining third in the Sa Pa area of Lào Cai Province. Stretching nearly 50 km, Ô Quy Hồ holds the record for the longest pass in Northwest Vietnam, even surpassing Pha Đin Pass (32 km) and Khau Phạ Pass (around 40 km). Its length, height, and treacherous curves have earned it the unofficial title of the 'King of Passes' in the region.
The high altitude of the Hoàng Liên Sơn range causes distinct climate differences at the Heaven Gate. During winter, while Tam Đường enjoys mild weather, Sa Pa is engulfed by bone-chilling cold, thick fog, and limited visibility. In summer, while Sa Pa remains cool and refreshing, Tam Đường experiences scorching heat. In particularly cold years, the pass summit may even be covered in snow.
On June 29, 2015, the Cầu Mây Waterfall and Heaven Gate area, located in the Hoàng Liên Sơn range in Sơn Bình Commune, Tam Đường District, Lai Châu, was officially recognized as a National Scenic Area by Decision No. 2248/QĐ-BVHTTDL.


4. Tiên Sơn Cave
Tiên Sơn Cave, also known as Bình Lư Cave, is located in Bình Lư Commune, Tam Đường District, Lai Châu Province, Vietnam. It is a karst cave system nestled in the limestone mountains, and it lies next to National Highway 4D. The cave is also referred to by several other names, including Đán Đón Cave, Pờ Ngài Tủng Cave, Đá Trắng Cave, and Bình Lư Cave. It was officially recognized as a National Historical and Cultural Site by the Ministry of Culture in Decision No. 1460/VH-QĐ on June 28, 1996.
The cave formed millions of years ago from a type of limestone known as carst rock. From the outside, Tiên Sơn Cave is hidden behind a thick forest, making it relatively unknown. However, once inside, visitors are greeted by a breathtaking and beautiful cave system! Looking out from within the cave, you can catch glimpses of the majestic Hoàng Liên Sơn mountain range, with the mist-covered peak of Fansipan in the distance. The area is also rich in folklore, especially the legend of the 99 mountains and 99 clear lakes of the Lự ethnic people.
Tiên Sơn Cave features 36 interconnected chambers that stretch along the two mountain slopes. Each chamber has been named after sacred figures such as Mẫu Âu Cơ, Lạc Long Quân, and Bà Chúa Kho. As you explore each section, you will encounter unique and fascinating formations. The further you venture into the cave, the larger the chambers become, and the space opens up to a more airy environment. Inside, you will find countless stalactites in various shapes, which create a magical atmosphere when illuminated. A stream runs through the cave, adding to its cooling effect, especially during the summer months.
The sound of trickling water and the gentle dripping of water from the cave ceiling onto the stone below creates a peaceful and soothing ambiance. Compared to many other caves, Tiên Sơn Cave retains its natural, pristine beauty. Visiting this cave allows you to forget the stresses of daily life and immerse yourself in the serene natural environment, leaving you feeling refreshed and at ease.


5. Lê Lợi Stele
The complex dedicated to King Lê Thái Tổ and the Lê Thái Tổ Stele is located 110 km southwest of Lai Châu city center, within the administrative boundaries of Lê Lợi and Pú Đao communes, Nậm Nhùn District, Lai Châu Province.
The temple was erected to honor the national hero, King Lê Lợi, who is renowned for his efforts in quelling rebellions in the Northwest region. The temple sits on an elevated position, offering panoramic views in all directions. The Lê Lợi Stele, a treasured artifact, can be found within the temple complex. In December of 1431, King Lê Thái Tổ had the stele inscribed at Pú Huổi Chỏ, on the northern bank of the Đà River, as a historical record for future generations. This inscription is referred to as the 'Old Stele'.
The stele commemorates the historical event in which King Lê Thái Tổ personally led the military campaign to suppress the rebellion of the chief Đèo Cát Hãn, who had allied with Kha Đốn (also known as Kha Lại), a traitor from the Lao Kingdom. Together, they disrupted the border areas, capturing Mường Muỗi (now part of Thuận Châu, Sơn La).
In response to the rebellion, King Lê Thái Tổ sent his general Tư Tề and his official Lê Sát to lead an army against the rebels. Afterward, the King personally led the forces to Phục Lễ (Ninh Viễn). The imperial army advanced along the Đà River by boat and on land, defeating the rebel forces. Upon reaching Đèo Cát Hãn's stronghold, both Đèo Cát Hãn and Kha Lại fled, and Kha Lại was captured and executed by the local people.
In December of 1431, after successfully pacifying the Northwest, the King passed through Lê Lợi Commune on his way back and had the stele inscribed to mark this significant event. The inscription reads:
'How dare these rebellious bandits escape punishment,
The border people have long awaited our rescue,
Rebels have always existed in history,
This land of danger is now forever subdued.
The winds blow, the cranes cry, striking fear into the enemy,
This land is now part of our nation's map.
This inscription carved into the stone, guarding the western borders of our land.'
This stele, which preserves the King's inscription, stands as an invaluable piece of cultural heritage. It serves as a testament to the King's victory over foreign invaders and local traitors who allied with them against the Vietnamese feudal state.
In 2005, the Sơn La Hydroelectric Plant project began, and the inscription was moved to avoid submersion. The inscription, which measures 2.62 meters in length, 1.13 meters in width, and 1.85 meters in height, weighs over 15 tons. In 2012, the Lê Lợi Stele was relocated from Pú Huổi Chỏ to the temple grounds, about 500 meters from its original location.
The Lê Lợi Stele, located in Lê Lợi and Pú Đao communes, Nậm Nhùn District, Lai Châu, was officially recognized as a National Historical Site under Decision No. 10/VH-QĐ on September 2, 1981, and listed under Category 185 of the Ministry of Culture's National Heritage Classification. In December 2016, the Lê Lợi Stele was designated a National Treasure under Decision No. 2496/QĐ-TTg by the Prime Minister.
The Lê Lợi Stele is an original, unique artifact and stands as a cultural masterpiece of this national hero.


6. Temple of King Lê Lợi
The Temple of King Lê Thái Tổ and the Lê Thái Tổ Stele (also known as the Lê Lợi Stele) is located approximately 110 km southwest of Lai Châu city center, within the Lê Lợi and Pú Đao communes in Nậm Nhùn District.
The temple was constructed to honor the national hero, King Lê Lợi, who played a key role in pacifying the Northwest region. Positioned on an elevated site with expansive views in all directions, the temple is an ideal place for both reverence and reflection. A notable feature of the temple complex is the Lê Lợi Stele. In December 1431, King Lê Thái Tổ ordered the inscription of a commemorative text on the Pú Huổi Chỏ rock on the northern bank of the Đà River, preserving the memory of this historical event for posterity. The inscription is referred to as the 'Ancient Stele'.
The inscription recounts the historical event when King Lê Thái Tổ personally led military campaigns against the rebellion of the chief Đèo Cát Hãn, who had allied with Kha Đốn (also known as Kha Lại), to disrupt the border areas and capture Mường Muỗi (now part of Thuận Châu, Sơn La).
The King personally led his forces into Phục Lễ. In December 1431, after successfully pacifying the Northwest, while returning through Lê Lợi Commune, Nậm Nhùn, King Lê Thái Tổ had the inscription carved into the rock to commemorate the victory and to remind the local chiefs of their duties to protect the borders.
According to Vũ Phong Oanh, the temple's chief monk from Lê Lợi Commune, the inscription carved by King Lê Thái Tổ remains an invaluable cultural heritage for the people of Lai Châu and for the nation as a whole.
In 2005, construction of the Sơn La Hydroelectric Plant began, and to prevent submersion, the inscription was relocated. In 2012, the Lê Lợi Stele was moved from Pú Huổi Chỏ to the temple grounds, approximately 500 meters from its original location.
The Lê Lợi Stele, located in the Lê Lợi and Pú Đao communes, Nậm Nhùn District, Lai Châu, was officially recognized as a National Historical Site. In late 2016, the stele was designated a National Treasure. In early 2017, the Temple of King Lê Lợi was also ranked as a National Historical Site by the Ministry of Culture, Sports, and Tourism.
Today, the Temple of King Lê Lợi serves not only as a place for the people of Lai Châu to honor their national hero, but also as an important cultural and spiritual site. Visitors to the temple during the early Spring months can enjoy stunning natural scenery while gaining insights into the local culture, with the lives of the people closely intertwined with the surrounding hydroelectric reservoir.
