Hanoi is a thousand-year-old city that wears its age on every corner — French villas peeling above pho stalls, incense curling from lakeside temples, motorbikes flowing like a river you learn to step into with faith. It rewards the walker and the sitter: the best of Hanoi is found on a low plastic stool with a coffee, watching the old quarter turn. Here are the places worth your time. Two things smooth the trip: a travel eSIM so Grab and maps work on arrival, and a browse of Klook or KKday for the Ha Long Bay and Ninh Binh day trips, which are far smoother booked ahead.
The Old Quarter and Hoan Kiem Lake
The heart of Hanoi is the Old Quarter, a maze of 36 streets each once dedicated to a single trade — silver, silk, tin, paper — still half-organised that way today. At its edge lies Hoan Kiem Lake, where the vermilion Huc Bridge arches to the Ngoc Son Temple on its little island, and locals do tai chi at dawn. Simply wandering here, coffee in hand, is the essential Hanoi experience; on weekends the surrounding streets close to traffic and fill with games and music.
The temples and the mausoleum
For the city’s history, walk the Temple of Literature — Vietnam’s first university, founded in 1070, a series of tranquil courtyards and pavilions. West of the centre, the solemn Ho Chi Minh Mausoleum holds the embalmed leader (closed some mornings and for annual maintenance), fronting a vast ceremonial square, with the delicate One Pillar Pagoda and the Presidential Palace grounds nearby. Dress modestly for the mausoleum, and expect airport-style security.
Train Street and the markets
A cult attraction, Train Street is a narrow residential lane where a working railway passes within arm’s reach of the cafés — sit for a coffee and, at the scheduled times, watch a train thunder past inches away (access is periodically restricted for safety, so check locally). For shopping and street food, the sprawling Dong Xuan Market and the Weekend Night Market running north from the lake are the places to graze and haggle.
A night at the water puppets
Uniquely Vietnamese, the Thang Long Water Puppet Theatre stages an art form born in the flooded rice paddies a thousand years ago — lacquered puppets dancing on a pool of water to live traditional music. The shows are short, charming, and a lovely early-evening counterpoint to a day on your feet.
Eating Hanoi
Hanoi may be the best street-food city in Asia, and it is gloriously specific. Chase pho at a dawn stall; bun cha (grilled pork and noodles, the dish Obama and Anthony Bourdain famously shared here); a crisp banh mi; and the city’s own invention, egg coffee — a silky meringue of egg yolk and condensed milk over strong coffee, best at the original Cafe Giang. End on a bia hoi corner with a glass of the day’s fresh draught beer for a few thousand dong.
Ha Long Bay and beyond
When you have a day (or two) to spare, the wonders are close. Ha Long Bay — its thousands of limestone karsts rising from jade water — is the classic overnight cruise; the quieter, land-locked Ninh Binh (“Ha Long on land”), with the sampan rides of Trang An and Tam Coc through cave-pierced karsts and rice fields, makes a superb day trip. Both are best arranged as a guided tour from the city.
Give Hanoi three or four days, learn to cross the road, sit low and often, and it becomes the Southeast Asian city travellers hold most stubbornly in their hearts.
Frequently asked questions
How many days do you need in Hanoi?
Three to four days: a day or two exploring the Old Quarter, Hoan Kiem Lake and the street food, a day for the Temple of Literature and the Ho Chi Minh complex, and one or two for a day trip or overnight cruise to Ha Long Bay or Ninh Binh.
Is Train Street in Hanoi safe to visit?
It is a working railway lined with cafés, and access is periodically restricted by authorities for safety. When open, you sit at a café and staff clear the track before a train passes within arm's reach. Check locally for current access and the day's train times, and follow the café staff's instructions.
What food should you try in Hanoi?
Pho at a dawn stall, bun cha (grilled pork with noodles), a crisp banh mi, and Hanoi's own egg coffee — a silky meringue of egg yolk and condensed milk over strong coffee, best at the original Cafe Giang. Finish on a bia hoi corner with fresh draught beer.
What are the best day trips from Hanoi?
Ha Long Bay, with its limestone karsts rising from jade water, is the classic overnight cruise. Ninh Binh — 'Ha Long on land' — offers sampan rides through Trang An and Tam Coc and makes an excellent day trip. Both are easiest arranged as guided tours from the city.
