Noi Bai airport taxi overcharge
01Touts outside arrivals quote flat fares of 700,000 to 900,000 VND for a trip that costs 380,000 to 420,000 VND by meter. They walk you to unmarked or cloned-logo cars parked beyond the official rank. Walk past everyone approaching you, open the Grab app, and book from the arrivals hall before you exit the building.
Cyclo ride with no agreed price
02Cyclo drivers near Hoan Kiem Lake and Dong Xuan Market invite you aboard without naming a fare, then demand 500,000 VND or more for a 10-minute loop. The fix is simple: agree a specific VND amount before you sit down, and confirm it is for the full ride, not per person or per minute.
Shoe-shine ambush on Dinh Tien Hoang
03A man crouches and begins polishing your shoes before you have agreed to anything, then demands 200,000 VND or more. This runs most heavily along Dinh Tien Hoang Street on the east side of the lake. Keep walking and say nothing; stopping to refuse is the move that prolongs the interaction.
Free tea, then a bill
04A friendly local invites you into a tea or coffee shop near the Old Quarter, insisting it is free or very cheap, then produces a bill for 500,000 VND or more. The person who invited you receives a commission from the shop. If you did not choose the venue yourself, do not enter it.
Fake Hanoi train ticket office
05Storefronts on Hang Bai Street and near the southern end of Hoan Kiem present themselves as official Vietnam Railways booking offices and add fees of 50,000 to 150,000 VND per ticket. The single legitimate booking counter is inside Hanoi Station on Le Duan Street, or you book at dsvn.vn directly. Any office not at the station itself is a travel agent, not a railway office.
