The honest brief
Vietnam is a long thin country — 1,650 km north to south — and the two ends are not the same place. Hanoi is old, dense, French-Tonkin brown-brick, with a food culture that takes broth seriously. Saigon (officially Ho Chi Minh City; everyone calls it Saigon) is hot, Cantonese-Chinese-influenced, all-night, motorbike-saturated. The middle (Hue, Hoi An, Da Nang) is its own thing — old imperial capital + a perfectly preserved 18th-century trading port + a beach city. A two-week first trip does all three sections; a one-week trip does Hanoi + Hoi An OR Saigon + the Mekong Delta.
It is one of the cheapest serious-food countries left for travelers — a bowl of pho in a Hanoi alley is $1.50 and is the best pho you will ever have. You will pay more for the same dish in any Western country and it will not be as good. Plan accordingly.

Country facts
When to visit
Vietnam has three weather zones. North (Hanoi, Sapa, Ha Long): October–April is dry and cool, even cold in Sapa (5°C at night in January). Center (Hue, Hoi An, Da Nang): February–August — typhoon season is September through November. South (Saigon, Mekong, Phu Quoc): December–March dry, April–November wet.
The country has no perfect-everywhere season — pick the region first, season second. February–March is the broadest sweet spot.
Money
Cash, in dong — and the zeros make every transaction feel like a Monopoly game. A 500,000-dong note is ~$20. Cards work in hotels and tourist restaurants in cities; outside of those, you're paying cash. The 1990s-era dollar economy is mostly gone; locals don't want USD anymore.
Tipping is light and growing — 5–10% in tourist-area restaurants, rounding up taxis. The classic scam, especially in Saigon: the xích lô (cyclo) driver who agreed to 50,000 dong delivers you and the price is now 500,000. Confirm price in writing on a phone before getting in, screenshot, show back at destination.
Food + dining etiquette
Pho is breakfast. The lunch and dinner crowds eat bún (noodles in cooler dishes — bún chả, bún bò Huế) and cơm tấm (broken rice). Order from the tiny plastic-stool place that's packed with Vietnamese commuters, not from the air-conditioned 'Pho Restaurant' on the corner. Bánh mì is a Saigon-French sandwich, the best $1 meal on Earth.
Chopsticks: never stuck in the rice. Spoon-and-chopsticks for noodle soups. The herbs in the basket on the table go in the broth by hand, torn, as you eat — not on the side as garnish. Fish sauce (nước mắm) on the table goes on rice and grilled meat, not in the soup.
Speaking the language
Vietnamese is tonal (six tones in the north, five in the south) and is much harder to fake than the Romance languages — even xin chào (hello, lit. 'I greet') takes a moment. Locals will not expect you to master it; a clean xin chào + cảm ơn (thank you) is enormous goodwill anyway.
Don't wai-bow Thai-style; that's not Vietnamese. A small head nod with hands at your sides is right. Bác / cô / chú / anh / em are honorific kinship terms (older man, older woman, uncle-aged, brother-aged, younger person) — pick wrong and it's comic; trying is appreciated. Em ơi to call the waiter.

What to pack
North in winter — actual sweater and a light jacket; you'll need them. Center and south year-round — light cotton, a long-sleeve for sun. A poncho for monsoon season anywhere. Sturdy walking shoes for Hanoi's broken sidewalks. A small daypack with a water bottle you can refill (most hotels have refill stations now).
Getting around
Vietnam Railways' overnight sleeper Hanoi–Hue or Hanoi–Da Nang is the train-romantic move and works — soft sleeper, four berths to a cabin, $40. The Reunification Express does Hanoi–Saigon end-to-end in 35h; nobody actually rides it as one trip. Domestic flights (Vietnam Airlines, Vietjet, Bamboo) are cheap and 2h.
Grab in cities. Don't rent a motorbike if you've never ridden one; Vietnam has 14,000 road deaths a year and the foreigner on a rented scooter contributes.
Where to actually go
One week: Hanoi (3) + Ha Long Bay (1 overnight cruise) + Hoi An (3), or Saigon (3) + Mekong Delta (2) + Phu Quoc (2). Two weeks: north + center, or all three. Skip first trip: Sapa in summer (rainy, leeches), Phu Quoc in low season (rough seas).
Common mistakes
Trying to do Hanoi + Hoi An + Saigon + Mekong + Phu Quoc in eight days. Renting a scooter on day one. Saying 'Saigon' in Hanoi (it's polite to say Ho Chi Minh City there; reverse is fine). Paying the first quoted price at a market — bargaining is expected, friendly, and 50% off the opener is the start.
Notes for the diaspora
Việt Kiều (overseas Vietnamese) are welcomed but the relatives will expect a lì xì envelope at any holiday and gifts (American vitamins, coffee, a bottle of nice scotch) on arrival. The food your bà made in California is a 1975 snapshot; the food in modern Saigon is a different generation of the cuisine.
Cultural notes
- Don't touch anyone's head, especially children — sacred body part
- Pass items with both hands as a sign of respect
- Remove shoes entering homes and most temples
- Bargaining expected at markets; restaurants are fixed price
- Don't drink tap water; iced drinks at street stalls are usually fine in Ho Chi Minh City
Universal courtesies
- Try a greeting in the local language even if it's the only word you know — it's appreciated everywhere.
- Match local dress norms when entering religious sites, government buildings, or rural areas.
- Ask before photographing people, especially children or in religious settings.
- Tipping customs vary — never assume your home country's expectation applies.
- Remove shoes when entering homes if your host does; watch their cue.
- Keep voices lower than at home in temples, mosques, museums, public transport.
- Hands and gestures mean different things across cultures — observe before reaching out.
- Cash + cards: rural areas often need cash; major cities take cards. Carry small notes.
- Don't compare countries to each other in front of locals — every culture stands on its own.
- If you don't know the etiquette, watching for 30 seconds usually teaches it.
