Hoan Kiem Lake

A small lake in the middle of the city with a path all the way round it, and the thing every visit to Hanoi is measured from. It is about a fifteen-minute walk to loop it. On one side is the Old Quarter, on the other the wide colonial streets of the French Quarter, and the lake is the seam between them.

Its name means the lake of the returned sword, from the legend of Lê Lợi handing back a magic blade to a golden turtle after driving out the Ming. There really were giant softshell turtles in it; the last known one died in 2016, and its predecessor is preserved in a case at Ngoc Son Temple on the island.

What it costs

⭐ Free, unfenced, and there is no closing time. The path is public pavement.

The only thing you pay for here is Ngoc Son Temple on its island, which is ticketed at the bridge.

When to go

⭐ Before seven in the morning is the best hour in Hanoi and almost no visitor uses it. The whole lakeside is exercising — badminton, tai chi, aerobics classes with speakers, people walking backwards on purpose. By eight it has emptied and become traffic.

⭐ From Friday evening until late Sunday the roads around the lake close to vehicles and become a walking street. It is the one time in the week when central Hanoi is quiet enough to hear, and it is when the city brings its children out.

Getting there

Everything in the Old Quarter is within a ten-minute walk. From the French Quarter, walk up past the Opera House; from Dong Xuan Market, straight down Hang Dao.

⚠️ The metro will not help you get here. Hanoi has two elevated lines — Cát Linh–Hà Đông and the first stretch of Nhổn–Hanoi Station — and neither serves the Old Quarter, the lake or the airport. They are genuinely useful for commuters and almost never useful for a visitor. Walk, or take a ride-hailing app.

If you only have an hour

Walk the loop anticlockwise from the north end, cross the red bridge to Ngoc Son Temple, and come out at the south end by the post office. That is the lake, the island, the Turtle Tower view and both quarters in about fifty minutes.

What people get wrong

⚠️ The Turtle Tower is not open and never has been. It sits on its own islet with no bridge; the little tower you can walk to is Ngoc Son, which is different and on the other side of the lake.

⚠️ Crossing the road is the skill this city asks of you. There is rarely a gap and waiting for one does not work. Step off the kerb and walk at a slow, even pace without stopping; the motorbikes read your speed and go around you. The two things that cause accidents are stopping in the middle and running back. Cars and buses will not swerve for you, so cross behind them, not in front. Give it one block and it stops being frightening.
