Vietnam is long — 1,600 km of it — and most itineraries chain three or four regions together. Everyone knows the domestic flights; fewer travellers realise how good the expressway network has become, and when a private car quietly beats flying altogether.
When the car wins
- Hanoi → Ha Long (2.5 h): no airport exists; the car is the way. Timed to cruise boarding, it is stress-free.
- Hanoi → Sapa (5 h): flying is impossible, the night train ends an hour away in Lao Cai. The expressway run is door to door in daylight, with the views included.
- Da Nang ↔ Hue (2–2.5 h): a flight saves nothing once airports are counted — and the Hai Van Pass is one of the coast roads of the world.
- Saigon → Mui Ne (4–5 h): no airport again; the private car beats the sleeper bus on every axis except price per person — and even that narrows for two or more travellers.
When to fly instead
North–south jumps: Hanoi to Da Nang, Saigon to Hanoi, anything to Phu Quoc. Two hours in the air beats twelve on the road; take the flight, then let a fixed-fare transfer handle the last kilometres at each end.
Making long drives good drives
- Leave mornings. City exits are gentler and daylight scenery is the point.
- One proper stop beats three fuel stations — tell the driver what you like: coffee, pho, viewpoints.
- Keep the essentials bag in the cabin — chargers, snacks, the toddler’s entertainment.
- Book legs as one itinerary — one confirmation, consistent cars, and drivers briefed on the whole plan.
