Hanoi

Is Hanoi safe?

Yes, from crime. Hanoi is one of the safest Asian capitals for a visitor in terms of violence, and most people walk the Old Quarter late at night without a second thought. What makes the city harder work is everything else: some of the dirtiest winter air of any capital, traffic that does not stop for pedestrians, bags snatched from passing motorbikes, and seasonal floods.

In Gallup's 2025 Global Safety Report, 88% of people in Vietnam said they feel safe walking alone at night where they live, more than in Japan or Australia. The UK Foreign Office says violent crime against foreigners is rare, and the US keeps Vietnam at Level 1. We score Hanoi 67 out of 100, just below Ho Chi Minh City (69), which has cleaner air but more street theft. Our Vietnam page covers the rest of the country.

The air is the biggest health risk

If you have asthma, heart disease or young children, read this first. Hanoi averaged 45.4 µg/m³ of fine particulate matterPM2.5Tiny airborne particles 2.5 micrometres across or smaller. They reach deep into the lungs and are the air pollutant most linked to early death.More in the glossary (PM2.5) in 2024, according to IQAir, more than nine times the WHO guideline and the fifth rise in a row since 2020. That made it the seventh most polluted capital in IQAir's 2024 ranking, far worse than Bangkok (18.9 µg/m³) and Saigon.

The problem is seasonal. In the cooler months, roughly November to March, an inversion layer traps fumes from millions of motorbikes, coal plants, construction dust and burning crop stubble. IQAir notes that smog has caused flight diversions at Vietnamese airports. From about April to October the rains wash the air cleaner.

What helps: check an air quality app each morning, wear a well-fitted N95 or KN95 mask on bad days, keep long walks along main roads for clear days, and choose a hotel with air purifiers in winter. Tap water is not drinkable; bottled water is cheap. International clinics in Tay Ho and Ba Dinh offer good care for insured visitors.

Crossing the street and getting around

Traffic is the main physical danger. Vietnam's government reported that road deaths fell more than 6% nationally in 2025, but the official count runs below WHO estimatesWHO road-death estimateThe World Health Organization's estimate of road traffic deaths per 100,000 people in a country, adjusted for deaths that police statistics miss.More in the glossary, and in Hanoi the experience matters more than the statistic. Motorbikes fill every street, ride on pavements and come the wrong way down one-way roads.

To cross, walk slowly and steadily, keep eye contact with riders and let them flow around you. Do not run or step back suddenly. Cars and buses will not swerve, so give them room. Ride-hailing apps (Grab, Be, Xanh SM) are cheap for cars and motorbike taxis, and the elevated metro lines from Cat Linh to Ha Dong and from Nhon towards the centre avoid the traffic entirely. Renting a motorbike yourself is a poor idea unless you are an experienced rider with an international driving permit; the FCDO warns that after a crash you can face criminal charges and a travel ban.

Theft and scams in the Old Quarter

Snatch theft is the crime to expect. The FCDOFCDO travel adviceThe UK government's travel advice for each country, which can advise against all travel or all but essential travel to specific areas.More in the glossary says thieves on motorbikes grab bags and phones in crowded and tourist areas, and that theft rises around Christmas and Tet. Keep your phone away from the kerb, carry your bag on the side away from traffic, and give up valuables rather than struggle. Thefts also happen on overnight trains to Sapa and the south, so lock bags to the bunk.

Scams are small but constant: vendors who put their carrying pole on your shoulder for a photo and then demand payment, cyclo drivers who renegotiate at the end, and bars that present bills without a menu. Do not leave your passport as a deposit with motorbike rental shops or landlords; the FCDO says they can keep it against claimed damage.

Nights out

Hoan Kiem Lake, the night market and Ta Hien beer street stay busy late, and the lake area closes to traffic on weekend evenings. The FCDOFCDO travel adviceThe UK government's travel advice for each country, which can advise against all travel or all but essential travel to specific areas.More in the glossary reports rape and sexual assault in tourist areas, often linked to unlicensed taxi drivers, and groping of women walking alone. It also warns of deaths from methanol in drinks bought in licensed bars and shops. Buy drinks yourself, avoid cheap spirits and rice wine of unknown origin, and book every ride through an app.

Floods and storms

Hanoi sits on the Red River, and flooding is the main natural hazard. When Typhoon Yagi struck northern Vietnam in September 2024, the river in Hanoi reached its highest level since 2004, thousands of people were evacuated from low-lying areas and parts of the city stood under a metre of water. Ordinary summer storms from June to September also flood streets within hours. If a typhoon is forecast, follow the national weather service and local orders, and stay away from the riverbanks outside the dykes.

How we scored it

Health and environment (42) is Hanoi's weakest factor because of the winter air, followed by traffic safety (45). Violent crime (86) and night safety (82) are its strengths. Theft and scams (66) and natural hazards (66) sit in between.
