Is Hoan Kiem Lake Worth Visiting?
Yes, it is the one place in Hanoi almost every visitor should see. It is free, central and easy to combine with the Hanoi Old Quarter, so you will probably pass it several times anyway. The lake itself is calm rather than spectacular; its value lies in the legend, the island temple and the chance to watch daily Hanoi life.

- Skip if: you have already seen it from your hotel and have only an hour left; choose the Temple of Literature instead.
- Short on time? Cross the Huc Bridge to Ngoc Son Temple (30 minutes), then walk to Turtle Tower viewpoint on the west shore.
The Legend of the Returned Sword
In the early 15th century Vietnam was under Ming Chinese rule. According to legend, the rebel leader Le Loi received a magic sword, its blade found by a fisherman and its hilt by Le Loi himself, and used it to win back independence. In 1428, after he became King Le Thai To, he was boating on the lake when a golden turtle rose from the water and asked for the sword. The king handed it back, and the lake, then known as Luc Thuy (“green water”), became Hoan Kiem, the “Lake of the Returned Sword”.
The story is taught to every Vietnamese child and explains why the turtle became a sacred symbol of Hanoi. It also inspired the most famous water puppet scene, performed nightly beside the lake.
History of Hoan Kiem Lake
The lake was once part of the Red River system and was much larger. Under the Le dynasty, royal boats trained here and the lake took its present name. In the 19th century the scholar Nguyen Van Sieu restored Ngoc Son Temple, built the Huc Bridge and the Pen Tower, and Turtle Tower was raised on its islet in 1886. Under French rule the western half was filled in and the boulevards around the lake were laid out, creating the French Quarter to the south.
The lake was home to a population of giant softshell turtles, revered as descendants of the golden turtle. The last known individual died in January 2016, a moment of national mourning. More background is available on Wikipedia.
What to See at Hoan Kiem Lake
1. The Huc Bridge
The red wooden bridge, whose name means “Bridge of the Morning Sunlight”, arches over the water to Jade Island. Built by Nguyen Van Sieu in the 1860s and rebuilt several times since, it is painted red for luck and is one of the most photographed spots in Vietnam, especially when lit at night.
2. Ngoc Son Temple (Temple of the Jade Mountain)
The temple honours Van Xuong, god of literature, General Tran Hung Dao, who defeated the Mongols in the 13th century, and La To, patron of physicians. Its courtyards, incense hall and lakeside pavilion make a quiet break from the traffic. Read the full Ngoc Son Temple visitor guide.
3. The preserved Hoan Kiem turtles
Inside the temple grounds, two preserved giant softshell turtles from Hoan Kiem Lake, from 1967 and 2016, are displayed in glass cases. They are the closest most visitors get to the creature of the legend.
4. Pen Tower and Ink Slab
Before the bridge, the five-tiered Pen Tower (Thap But) rises from a rocky mound with the inscription “Tả Thanh Thiên”, “writing on the blue sky”. Next to it, the Ink Slab gate (Dai Nghien) is shaped like half a peach-shaped inkstone resting on three toads. Together they symbolise scholarship.
5. Turtle Tower (Thap Rua)
The small three-storey tower on an islet in the south of the lake was built in 1886 and mixes Vietnamese and French styles. It is not open to visitors, but the best views are from the west shore along Le Thai To Street and from cafés on the north shore.
6. King Le Thai To statue and park
On the west shore, a bronze statue of King Le Thai To (Le Loi) holds the legendary sword. The small park around it is a favourite spot for morning exercise and evening strolls; the Le Thai To Temple is nearby.
7. Hoa Phong Tower and the eastern shore
On the east shore stands Hoa Phong Tower, the only surviving gate of the 19th-century Bao An Pagoda, demolished under French rule. Across the road are the old Hanoi Post Office and the Hanoi People’s Committee building, both from the French period, with Ly Thai To flower garden just behind.
8. Dawn at the lake
From about 5:00 the lake fills with people doing tai chi, aerobics, ballroom dancing and badminton. It is the best time to feel the rhythm of Hanoi and to take photos without crowds.
9. The weekend walking street
From Friday evening to Sunday night the streets around the lake close to cars. Families, street performers, folk games and music fill the area, and the atmosphere spills into the Old Quarter night market.
10. Water puppets at Thang Long Theatre
On the north-east shore, the Thang Long Water Puppet Theatre stages Vietnam’s unique art of water puppetry, with live traditional music, several times a day. The show lasts about 45–50 minutes and includes the legend of the Returned Sword.
