Tu Lan Caving Expedition: World’s 3rd Largest Cave

World’s 3rd Largest Cave : Tu Lan

Picture & text courtesy : Internet

Officially discovered in 2009, Tu Lan gained attention in 2011 when a picture by Carsten Peter of the Ken Cave’s glowing green pools won National Geographic’s Photograph of the Year. Tourism has grown steadily, but the caves, nestled near the Laos border, around 70 kilometres northwest of Phong Nha, remain wonderfully untouched, attracting only about 2,000 visitors this year.

The “hottest” cave in Vietnam right now is nearby Hang Son Doong, which made The New York Times’s list of 52 Places to Go in 2014 and is considered to be the largest in the world by volume (one chamber is five kilometres long, another 182 metres high). Discovered in 1991 by a Vietnamese farmer, it was sized up by scientists in 2009 and finally opened to the public earlier this year.

Day 1 & 2


Hanoi, the capital of Vietnam, is known for its centuries-old architecture and a rich culture with Southeast Asian, Chinese and French influences. At its heart is the chaotic Old Quarter, where the narrow streets are roughly arranged by trade. There are many little temples, including Bach Ma, honoring a legendary horse, plus Đồng Xuân Market, selling household goods and street food.

Lake Hoan

The tale goes that Le Koi King came across a shining metal bar when he visited his friend. It turned out that his friend caught the bar in one of his attempts for fish. The King asked for the bar, brought it home and moulded it into a sword. All of a sudden, there was two words printed on the sword “Thuan Thien” (harmonious with heaven).

Le Loi then understood that the sword was a gift from heaven. He used it for the battle against the war with a neighbouring country. At the beginning of 1428, when peace prevailed, on one of his trip to the Thuy Quan (now Hoan Kiem) Lake, there was a tortoise rising above water and shouting: “Please return the sword to the Dragon King”. Without hesitation, the King threw the sword to the lake. The tortoise took the sword and dove down the water. From then on, Thuy Quan became Hoan Kiem lake.

Nagoc Son Temple

Ngoc Son Temple (Temple of the Jade Mound) is located on an islet in the middle of Hoan Kiem Lake. According to the ancient documents still preserved in the temple, it was built in the autumn of 1841.

The temple came under comprehensive repair in 1865 by Nguyen Van Sieu, an eminent scholar of the old Thang Long Capital. Other projects were also newly built or upgraded that created a new complex of relics with a harmonious architecture. These include Ngoc Son Temple, The Huc Bridge, But Thap (Pen Tower) and Dai Nghien (Ink Slab)

Ta Hien

Ta Hien is a small street lying in famous Old Quarter of Hanoi, near Hoan Kiem Lake. The street just stretch 200 meters, but it is one of the most crowded streets in Old Quarter particularly and in Hanoi generally. Ta Hien has the most specific features of both old Hanoi and modern Hanoi. It is named “international crossroad”, drawing many foreign visitors and also Hanoi people.On the small and crowded street of Ta Hien, you can find variety of best Hanoi street foods such as Nem chua, Vietnamese bread, noodles, sweet porridges,… Especially, in summer, Ta Hien is famous for beer.

Hoa Lo Prison:

A former prison in Hanoi originally built by the French in colonial times, primarily for incarcerating political prisoners. Later, during the Vietnam  War, the prison was one of the places where the North Vietnamese detained shot-down American pilots, who sarcastically nicknamed the place “Hanoi Hilton”. The museum is divided into several sections, relating to different periods in the site’s history. Starting in the wing to the east of the main entrance (the outside of which still bears the original French name of the prison: “Maison Centrale”), you first get to a small section about the village that had to make way for the prison.
