Vietnam requires most Western travelers to get an e-visa (around $25, up to 90 days), except for roughly 38 exempt nationalities who get 14-45 days visa-free. Timing depends on region, and a travel eSIM is worth setting up before you land.
Vietnam is long enough, north to south, that "best time to visit" really depends on your route — worth mapping out before you book flights.
Best time to visit
Feb-Apr suits the north (Hanoi, Sapa, Ha Long Bay). Feb-May and Aug-Oct suit central Vietnam (Hoi An, Hue, Da Nang). Dec-Apr suits the south (Ho Chi Minh City, Mekong Delta). Trying to cover all three regions in one trip means accepting a compromise on at least one leg.
Getting around
Overnight trains and budget flights connect the major north-south route cheaply. Within cities, Grab handles rides and food delivery reliably; motorbike rentals are common for longer stays but require real caution in city traffic.
Top things to do
Wander Hanoi's Old Quarter and eat at a plastic-stool street stall at least once
Cruise or kayak Ha Long Bay, ideally on an overnight boat to skip the day-trip crowds
Get a tailored outfit made in Hoi An — still one of the best-value tailoring scenes anywhere
Explore the Mekong Delta by boat from Can Tho for floating markets
Try pho and banh mi from a local spot, not a tourist-menu restaurant
Budget tips
Street food and local buses stretch a budget significantly further than hotel restaurants and private transport. Homestays and budget hotels are widely available and often better value than international chains.
Where to stay
Hanoi's Old Quarter is convenient but noisy; the West Lake area is quieter with easier access to cafes if you're staying longer.
Saily: Use code Sahrzad15 at checkout. Built-in ad and tracker blocking is a nice bonus if you're working online while there.
Airalo: Good backup option with slightly wider regional coverage.

Frequently asked questions
Do US citizens need a visa for Vietnam?
Yes. The US isn't on Vietnam's visa-exemption list, so American travelers need an e-visa — about $25 online, valid up to 90 days. The same applies to Canada, Australia, and New Zealand.
Which countries can enter Vietnam visa-free?
Around 38-39 nationalities qualify as of 2026, mostly Western European, with stays of 14-45 days depending on passport. Confirm your specific nationality's current status before booking.
What's the best time of year to visit Vietnam?
It depends on region — Vietnam spans several climate zones. Roughly: Feb-Apr for the north, Feb-May and Aug-Oct for central Vietnam, and Dec-Apr for the south.
Do I need an eSIM for Vietnam?
It's worth having one. Vietnam's mobile networks are fast even outside major cities, and a travel eSIM means you're connected for Grab and maps the moment you land.
