A Vietnam Trip Plan That Doesn't Backtrack Across the Map

Type 'Vietnam trip plan' into any AI tool and you'll get the same answer in under five seconds: Hanoi, Halong Bay, Hoi An, Ho Chi Minh City, in that order or reversed. It's not wrong — Vietnam is one of the few countries shaped like an actual itinerary, a long strip running roughly 1,650km north to south where the obvious route is also the correct one. The part the AI skips is everything around the route: which end to fly into, how long each stop genuinely needs versus how long you'll spend there because the train schedule said so, and the e-visa form that wants a hotel address before you've booked a hotel. I've planned a few trips through this part of the world, and Vietnam is one of those countries where the route is the easy 20% and the logistics are the other 80%.

ℹ️ Vietnam in One Line

For a first trip: fly into Hanoi, spend 2-3 days there with a Halong Bay overnight, fly to Da Nang for 2-3 days based in Hoi An, then fly to Ho Chi Minh City for the last 2-3 days. Nine to ten days, one direction, zero backtracking.

Vietnam runs north to south for around 1,650km, and almost every itinerary — yours, mine, the one Vani would generate, the one a travel agent in Bangalore would draw on a napkin — ends up doing some version of Hanoi, Halong Bay, Da Nang or Hoi An, and Ho Chi Minh City. The direction matters less than picking one and not deviating: fly into Hanoi and out of Ho Chi Minh City (or the other way round), and you never cover the same ground twice.

For nine to ten days, the shape is roughly: 3 days in Hanoi, including a Halong Bay overnight cruise that eats a full day in transit either way; 2-3 days around Da Nang and Hoi An, reachable by a short domestic flight from Hanoi; and 2-3 days in Ho Chi Minh City to close out. Everything else — a side trip to Ninh Binh, an extra day in Hue, the Mekong Delta — gets added if you have the days and dropped if you don't.

Budget shapes the route too. A Hanoi-Hoi An-Saigon route with domestic flights between each leg typically keeps the total trip cost lower than people expect, because internal flights in Vietnam are cheap relative to the distances covered — often comparable to or less than a long taxi ride in the same city. The bigger cost swings come from accommodation choices and how many guided day trips you stack on, not from the route itself.

The visa question tends to surface around 11pm, two weeks before departure, when someone searches 'do I need a visa for Vietnam from India' and finds eleven answers, several of them outdated. The current answer: yes, an e-visa, applied for online — but it asks for an address you'll book accommodation against, which means the visa application has to come after at least a provisional hotel booking, not before.

A Halong Bay day trip from Hanoi means roughly four hours of driving for about three hours on the water. An overnight cruise covers the same round trip but adds a sunrise on the bay, a kayaking session, and a night you weren't going to spend doing anything else anyway. The cost difference is smaller than the time difference suggests it should be. (Fair enough if your Hanoi schedule is already packed and you genuinely can't spare the night — but if the choice is between 'tight' and 'one night on a boat', the boat wins.)

Da Nang and Hoi An are about 30 minutes apart, and the split confuses people who book a hotel near the airport because that's where the flight lands. Da Nang has the airport and the beaches; Hoi An has the old town, the lanterns, and the reason you came. Base yourself in Hoi An and treat Da Nang as a transit point and an optional half-day for the Marble Mountains or a beach afternoon. The flight from Hanoi to Da Nang is about 1.5 hours. The alternative — an overnight train — takes upwards of 17 hours, and 'character-building experience' is doing a lot of work in every blog post that recommends it.

Ho Chi Minh City works best as the final stop — it's the biggest city, the one with the most going on, and the easiest to fly out of internationally. From Saigon, the Mekong Delta is a single day trip: a few hours each way, a boat ride through the floating markets and canals, back by evening. It doesn't need its own overnight stay unless you specifically want a night on the river, in which case build it in as an extra day rather than squeezing it into the Saigon leg. The Cu Chi Tunnels are the other common day trip from the city, and the two don't combine well into a single day — pick one.

If you've got an extra two or three days at the end, Phu Quoc — a short flight from Saigon — works as a beach add-on, though it changes the trip from 'cultural circuit' to 'cultural circuit plus beach week', which is a different trip and worth deciding on deliberately rather than bolting on at the last minute.

For a first Vietnam trip under two weeks, three stops is the ceiling — Hanoi, Hoi An, and Ho Chi Minh City, with Halong Bay folded into the Hanoi leg as an overnight rather than counted separately. Each stop gets a minimum of two nights, because one-night stops are mostly spent checking in, finding dinner, and checking out, with the actual destination squeezed into the gaps. Add a fourth stop only if you're past two weeks, and even then, resist the urge to add Hue or Ninh Binh just because they're 'on the way' — on a map, everything in Vietnam is on the way to everything else, which is exactly why the three-stop version keeps working.

Tell Vani you're planning a Vietnam trip — dates, starting city, how many people — and it builds the day-by-day version of the route above: Hanoi, Halong Bay, Hoi An, Ho Chi Minh City, with accommodation areas and activities slotted in. Ask it to swap the Mekong Delta day trip for an extra day in Hoi An, or push the whole trip back a week, and it regenerates the plan rather than making you start over. It also searches live flights and hotels through G8Trip's planning tool, and links out to Atlys for the e-visa application and Saily for an eSIM, so that part isn't spread across four different tabs. If Southeast Asia is the bigger plan, the Singapore trip plan follows the same one-direction logic for a shorter add-on stop.

What it doesn't do: fill in the e-visa form for you, or tell you whether you're someone who'll enjoy a 17-hour train as 'an experience' or as 17 hours on a train. Some of trip planning is logistics, and some of it is just knowing yourself. Vani's good at the first part.

The itinerary above takes about ninety seconds to generate and roughly nine days to live through. Only one of those numbers is negotiable. Pack light — you're moving every two to three days, and Hanoi airport security has opinions about which bag goes where that Vietnam customs has not communicated to anyone in advance.
