All Quick Tips

Vietnam is an easy country to travel, and a little preparation makes the first 48 hours effortless. None of this is complicated. It is just the short list of things that are far nicer to handle before you are standing in an arrivals hall. Sort these and you can spend your energy on the good part.

Before and just after you land

Your visa, sorted early

Most visitors need a visa or e-visa, which is usually applied for online in advance. Check the current rules for your nationality well before you fly, since requirements and stay lengths change. (If you travel with us, we guide this step for you.)

Get connected with an eSIM or SIM

A local eSIM or a cheap SIM from the airport gives you data for maps, ride apps and translation from the moment you arrive. Reliable mobile data is the single thing that makes everything else easy.

Cash and cards

The dong is cash-friendly, and small vendors, markets and taxis often prefer it, while cards and ride apps cover hotels and larger spends. Carry some cash, keep smaller notes handy, and use ATMs from established banks.

A few words of Vietnamese

Learning xin chao (hello) and cam on (thank you) goes a long way and is always appreciated. A translation app covers the rest and turns street food into an adventure.

Simple etiquette

Dress modestly at temples, remove your shoes when entering homes, and keep your cool when bargaining. A friendly, patient manner opens doors everywhere in Vietnam.

Stay well in the heat

It is warm and humid in much of the country, so drink plenty of water, ease into the street food, and enjoy the local coffee, which is superb and everywhere.

The takeaway

Sort your visa, get mobile data, carry a little cash and arrive with an open, easygoing attitude. Do that and Vietnam meets you more than halfway.
