Plan 10–14 days for a first visit to Vietnam’s main highlights; allow 2–3 weeks to travel from north to south at a more relaxed pace. March and April are often the best months for a countrywide trip, although conditions vary by region.
Vietnam is long and travel between regions takes time, so avoid packing in too many stops. Domestic flights can save time on longer journeys.
Weather varies year to year, and the rainy season does not mean constant rain. If traveling during Tet (Vietnamese Lunar New Year, usually in January or February), book ahead: transport and accommodation can be busy, and some businesses close.
