Hanoi

Stay in or beside the Old Quarter on a first visit. The Old Quarter puts the lake, the food streets and the night market at your door. Rooms are cheap, but street noise starts before 7 am — ask for a back-facing room. The French Quarter, just south of the lake, trades buzz for wide streets, colonial hotels and quiet nights; good for couples who still want to walk everywhere.

Tay Ho (West Lake) is the leafy district where expats live — lakeside cafes, better-value apartments, and a 15-minute Grab to the sights. Ba Dinh, near the Mausoleum, is convenient for morning sightseeing but dull after dark. Mid-range hotels across the city run about ₫800,000–₫1,500,000 ($30–$57) a night; clean budget rooms cost half that.

Hanoi is cheap even by Southeast Asian standards. A bowl of pho is ₫40,000–₫60,000 ($1.60–$2.30), a banh mi ₫25,000–₫40,000 ($1–$1.60), and a glass of fresh bia hoi beer under ₫15,000 (well under $1). Museum and temple tickets are almost all under ₫100,000 ($4).

A full day — three meals out, two ticketed sights, Grab rides — fits inside about ₫700,000 ($27) per person before your hotel. The two things that cost real money are Ha Long cruises and Western-style restaurants, which charge close to international prices. Carry cash: street food, markets and small cafes are dong-only.

Ha Long Bay is the headline, but it is not the only good day out.

Ninh Binh (Tam Coc and Trang An). Limestone karsts rising from rice paddies — often called "Ha Long on land" — seen from a rowed sampan that slides through river caves. About 2 hours each way; full-day tours cost roughly ₫800,000–₫1,100,000 ($30–$42) with lunch. If you have booked an overnight Ha Long cruise, this is the day trip to add.

Perfume Pagoda. A river ride and cable car to a cave temple, about 2 hours out. Atmospheric, but a long day for one sight — skip it on a short trip.

Sapa is not a day trip. The mountain rice terraces are 5–6 hours away by road. Go only if you can give it two nights; a one-night dash is mostly bus.

Hanoi works with kids if you pace it gently. The water puppet show is the banker: under an hour, live music, and odd enough to hold a four-year-old's attention. The Ninh Binh sampan ride (see Day trips) suits ages five and up — ask for child life jackets before boarding, as not every boat carries them. On weekends, the streets around Hoan Kiem Lake go car-free, giving children rare space to run.

For sleeping, the French Quarter beats the Old Quarter with a family — quieter nights and wider pavements for a stroller. Traffic is the one real hazard: hold hands, step off together, and cross at one slow, steady pace so the motorbikes can read you. Keep it to one sight per morning, rest through midday, and save the night market for the end of the day.

October to April is the best window — dry and cool. Unlike most of Southeast Asia, Hanoi has a real winter: December and January can drop to 10-15°C, so pack a light jacket.

May to September is hot, humid and rainy, and typhoon systems occasionally disrupt Ha Long cruises in August and September. Trips still work then; just keep a buffer day around the cruise.

Walk the Old Quarter and use Grab for everything else. Grab bikes cost almost nothing for short hops; a car across town is ₫50,000-₫100,000 ($2-$4). Crossing the road is the real skill — walk slowly and steadily, and the motorbikes flow around you.

From Noi Bai airport, a Grab or hotel car takes 40-50 minutes and costs about ₫250,000-₫350,000 ($10-$13). Skip the airport taxi touts.

Hanoi anchors the northern half of the classic Vietnam route: Hanoi + Ha Long Bay (3-4 days), then fly south to Da Nang and Hoi An (3 days), and finish in Ho Chi Minh City (2 days). Ten days does the whole country.

Short on time? Hanoi + Ha Long alone makes a strong 4-5 day trip — better than splitting three cities across five days. See our full Vietnam guide for seasons and route ideas.
