Why this guide
About this guide
Vietnam's entry process changed significantly in 2026. The e-visa now accepts applicants from every country worldwide, granting stays of up to 90 days on either a single or multiple-entry basis, with no local sponsor or agency involvement needed. Travelers do, however, need a passport valid for at least six months past their arrival date and at least two blank pages — both are hard pre-boarding requirements enforced by airlines. Citizens of Germany, France, the United Kingdom, Japan, South Korea, and nine other nations qualify for 45-day visa-free entry, while most ASEAN passport holders receive 30 days. Anyone arriving directly into the Phu Quoc Special Economic Zone receives a 30-day stay regardless of nationality.
Vietnam stretches more than 1,600 km from north to south, which means weather conditions vary considerably across the country at any given time. The north experiences four seasons with cool winters, the central coast faces heavy monsoon rain from August through November — typhoons affecting Da Nang, Hoi An, and Hue are a real logistical consideration during that period — and the south runs on a straightforward two-season tropical calendar: dry from November to April, wet from May to October. Temperatures across the country generally fall between 21°C and 35°C, with average humidity around 85%. Lightweight, breathable clothing covers most situations, though anyone heading into northern mountain areas such as Sapa between November and February will need warm layers. The November-to-April window offers the most practical conditions across the country overall.
Pre-trip health preparation requires attention to timing and specifics. Vietnam has no mandatory vaccination requirements at the border in 2026 — no COVID-19 certificate, yellow fever card, or other proof of immunization is checked on arrival. That said, both the CDC and WHO recommend consulting a travel clinic at least four weeks before departure to discuss Hepatitis A, Typhoid, Hepatitis B, Japanese Encephalitis, Rabies, Polio, Tdap, and MMR coverage. Dengue fever is a year-round mosquito-borne risk with no available vaccine, so packing 50% DEET repellent and wearing long-sleeved clothing at dawn and dusk is a practical necessity rather than a precaution. From 1 July 2026, all international arrivals must submit a health declaration — electronically or on paper — within the seven days before travel, and temperature checks apply on arrival. On the customs side, foreign currency above USD $5,000 and Vietnamese dong above VND 15,000,000 must be declared at the red channel, and duty-free limits cover 1.5 litres of spirits over 22% ABV or 2 litres of wine or beer, plus 200 cigarettes, 20 cigars, or 250 g of loose tobacco — not in combination.
Key facts & good to know
The honest pacing
We put this checklist together because Vietnam's entry rules, health requirements, and customs thresholds shifted enough heading into 2026 that older packing guides now contain outdated information. Whether we're crossing from Hanoi down to Ho Chi Minh City or spending two weeks on the central coast during shoulder season, the practical details — what paperwork to complete before boarding, which vaccines to discuss with a travel clinic, what the weather will actually do to our gear choices — are what shape a trip more than anything else.
What follows covers four core areas: visa and entry requirements, regional climate and what to pack for each zone, health and vaccination preparation, and customs rules for arrivals. We've organized it chronologically, starting with what needs to happen weeks before departure and working through to what goes in the bag. The Digital Arrival Card required at Tan Son Nhat Airport since 15 April 2026 and the mandatory health declaration effective from 1 July 2026 are both things we need to handle before we board — not at the immigration counter — so we've flagged those clearly.
