- What it is
- A chain of pagodas, temples and hermitages across the hills north-east of Hanoi. UNESCO listed it on 12 July 2025 as the Yen Tu – Vinh Nghiem – Con Son, Kiep Bac Complex of Monuments and Landscapes. It is Vietnam's ninth World Heritage site and has twelve component sites.
- Where
- The sites lie in three places. Yen Tu mountain is in Quang Ninh province, about 120 km from Hanoi and 50 km from Ha Long. Con Son and Kiep Bac are in what is now Hai Phong city (Hai Duong province until 2025), about 75 km from Hanoi. Vinh Nghiem Pagoda is in Bac Ninh province (formerly Bac Giang).
- The story
- In the 13th century the Tran dynasty beat back three Mongol invasions. King Tran Nhan Tong then gave up the throne, became a monk on Yen Tu and founded Trúc Lâm, the "Bamboo Forest" school of Zen, which is distinctly Vietnamese.
- Yen Tu
- A 1,068 m mountain with pagodas, stupas and shrines strung along the pilgrims' path to Dong Pagoda, a small bronze temple on the summit.
- Con Son and Kiep Bac
- Con Son Pagoda was one of the great centres of Truc Lam, and later the home of the scholar and statesman Nguyen Trai. Kiep Bac Temple, 8 km away, honours General Tran Hung Dao, who commanded the victories over the Mongols and is worshipped as a saint.
- Getting there
- By car, Con Son and Kiep Bac are 1.5–2 hours from Hanoi and Yen Tu 2–2.5 hours. Buses run to Uong Bi for Yen Tu and to Chi Linh for Con Son, with a taxi for the last stretch. Most visitors hire a car with a driver, or stop at Yen Tu on the way to or from Ha Long.
- Best time
- October to December for dry, clear walking weather. The spring festival season, roughly February to April, is the most atmospheric and by far the most crowded. Summer is hot and humid for the climb.
- How long
- Yen Tu takes a full day. Con Son and Kiep Bac together take half a day. Seeing all of them comfortably needs two days.
