Vietnam 3-week itinerary: north to south with a real budget breakdown

Vietnam is 1,650km from north to south. The country is extraordinary; the length of it is a planning variable that demands respect.

Vietnam is 1,650km from north to south. Most first-time visitors don't fully appreciate what this means for a three-week trip until they're on the third overnight bus of the fortnight, stiff-backed and slightly resentful, watching another highway pass in the dark. The country is extraordinary; the length of it is a planning variable that demands respect.

The rule that makes a three-week Vietnam trip work: budget one transit day for every five sightseeing days, or your itinerary ends up with sightseeing days that are half transit. Three weeks gives you 21 days; subtract 4 transit days and you have 17 days of actual experience. That's plenty if you use them well.

In the broader Southeast Asia context, Vietnam sits alongside Thailand as the two most-considered first SE Asia destinations. This guide covers the north-to-south structure most travellers use and why it's the better direction for first-timers.

North to south or south to north?

North to south for first-timers. South to north for repeat visitors or those with specific monsoon timing needs.

The north-to-south argument: you arrive in Hanoi, which is the more immediately legible of the two major cities for first-time visitors — smaller, more walkable, a distinct quarter system. You move south gradually, building familiarity with the country. You end in Ho Chi Minh City, which is kinetic and energetic and makes a stronger final impression for having seen the north first. Flight logistics (arrival into Hanoi, departure from HCMC) are efficient and avoid backtracking.

The south-to-north case applies primarily to weather: December–February is the best time to visit the south, which means arriving into HCMC at that time and ending in Hanoi makes seasonal sense. The central coast (Hoi An, Da Nang) also has its own wet season from October to January that complicates north-to-south timing in autumn.

This guide assumes north-to-south structure and a travel window of late winter to early spring (February–April), which is the most consistently good weather window across the whole country.

Days 1–4: Hanoi

The Old Quarter is the entry point; Hoan Kiem Lake is the centre; West Lake is where you want to be by day two.

Hanoi's Old Quarter is the 36-street neighbourhood where traditional trade guilds occupied specific streets — Silk Street, Paper Street, Tin Street — and their names remain even as the commerce has shifted to everything from tourist T-shirts to serious traditional craft. The streets are narrow, the traffic is dense, and the noise is constant. Walking it for the first morning gives you the Hanoi orientation. Staying in it for four days gives you sensory overload.

Day 1: Old Quarter on foot in the morning. The Bach Ma Temple (one of the four ancient guardian temples of Hanoi, small and genuine, free entry) in a side street. Hoan Kiem Lake in the afternoon — circumnavigate the lake, cross the red bridge to Ngoc Son Temple (€1.50 entry). Evening: Bia Hoi (the fresh beer culture of Hanoi — sitting on a small plastic stool on Ta Hien Street with a glass of beer brewed that day for 10,000 VND / €0.37 is a Hanoi essential).

Day 2: Ho Chi Minh Mausoleum complex in the morning (the mausoleum containing Ho Chi Minh's body, free but with a dress code and strict no-photography rules inside; the One Pillar Pagoda adjacent is worth 15 minutes). The Vietnam Museum of Ethnology in the afternoon — the best museum in Vietnam, covering the 54 ethnic groups across the country with genuine depth and English-language materials (€3.50 entry).

Days 3–4: Day trip to Ninh Binh, 90km south of Hanoi (3 hours by train or bus, from €3). Ninh Binh is what Ha Long Bay looks like on land — limestone karsts rising from rice paddies and rivers, boat trips through cave systems, cycling between pagodas. Less crowded than Ha Long, genuinely beautiful, and frequently recommended over Ha Long Bay by travellers who've done both.

Days 5–7: Ha Long Bay or Bai Tu Long Bay

The honest comparison: Bai Tu Long is less crowded and nearly as beautiful. Ha Long is more iconic and harder to experience without a tour.

Ha Long Bay is a UNESCO World Heritage Site with 1,600 islands and islets rising from the Gulf of Tonkin. It's one of the most visually distinctive natural landscapes in Asia and has been so heavily developed for tourism that independent access is essentially impossible — the boats and the bay are inseparable, and the boats require booking through tour operators.

The standard Ha Long overnight cruise (from €60/person for basic, €120+ for mid-range) puts you on a boat with 15–30 other tourists, covers the same highlights circuit, and delivers real karst scenery from the water. The basic boat experience is fine; spending more produces better food and a quieter onboard atmosphere.

Bai Tu Long Bay is the adjacent bay to the northeast, less visited, accessible via the same Halong City entry point but through operators who specifically run Bai Tu Long rather than the main Ha Long circuit. The karst scenery is comparable; the boat density is a fraction of Ha Long's. Prices are similar to mid-range Ha Long tours. If you're spending the night on water, Bai Tu Long is the better choice.

Days 8–10: Hoi An

The most photogenic town in Vietnam and the best food scene. Can overstay easily.

Hoi An is a 15th-century trading port with intact Japanese merchant houses, Chinese assembly halls, French colonial buildings, and Vietnamese shophouses all within a walking-distance old town. It's also a tailoring centre (custom clothing made in 24–48 hours from €40 for a shirt to €150 for a suit), a lantern-making destination, and a food scene that punches significantly above its size.

The old town is illuminated by lanterns in the evening in a way that justifies every photograph you've already seen. It's busy in peak season (the peak of the crowds coincides with the peak of the light) and genuinely atmospheric from 5pm to 9pm before the tourist restaurant strip closes. Walking the Thu Bon river in the morning, before the boats and the tour groups, is an entirely different experience.

Hoi An food: cao lau (the thick wheat noodles in pork broth that are made with water from a specific well in the town and therefore technically not authentic outside it), white rose dumplings, banh mi from the Banh Mi Phuong cart (Madam Khanh's is the other famous one; the debate is productive because both are good). Budget €3–6 for any of these. Budget €15–25 for a good restaurant dinner.

Days 9–10 optional extension: the marble mountains (Ngu Hanh Son) are a cluster of marble and limestone hills 10km south of Da Nang, with Buddhist shrines and caves inside the mountains (€1.50 entry, €0.50 for the lift). My Son Sanctuary (an hour from Hoi An, UNESCO-listed Hindu temple complex from the Cham Kingdom, €15 entry) requires a half day and is worth it.

Days 11–13: Da Nang and the central coast

Da Nang has transformed from a transit city to a destination. The beaches are excellent.

Da Nang is 30km from Hoi An by road and has been significantly developed for domestic Vietnamese tourism over the last decade. My Khe Beach — a 30km stretch of sand — is genuinely good, the seafood restaurants along it are excellent and cheap (whole grilled fish for €5–8), and the city's Dragon Bridge (which breathes fire on weekend evenings at 9pm) is one of those unexpectedly spectacular bits of infrastructure worth seeing once.

The Hai Van Pass — the mountain road between Da Nang and Hue that was famously driven on Top Gear — is one of the most scenic drives in Vietnam. Renting a scooter (€5–8/day) for the half-day pass crossing is the standard independent traveller approach; guided Easy Rider motorcycle tours do the same journey more safely if you're not comfortable on two wheels. The pass gives you views over both the Da Nang bay and the northern coast simultaneously.

Days 14–17: Hue and onwards to Ho Chi Minh City

Hue was Vietnam's imperial capital. Give it two nights rather than one.

Hue's Imperial Citadel (€10 entry, the Forbidden Purple City at its centre, modelled after Beijing's Forbidden City) covers 5 square kilometres and requires a full morning. The royal tombs outside the city — particularly Tu Duc's tomb (€10), a lakeside retreat of extraordinary refinement — are better reached by bicycle or hired motorbike than by organised tour. Hue cuisine is the most distinctive in Vietnam — the royal court cooking tradition produced bun bo Hue (a spicy beef noodle soup significantly richer than pho), banh beo (steamed rice cakes with shrimp), and com hen (clam rice).

Flying from Hue to Ho Chi Minh City is the efficient option (Vietnam Airlines, VietJet, or Bamboo Airways, from €25 one way, 1h 20min). The Reunification Express train (22 hours from Hue to HCMC) is the experience option — the route follows the coast past beaches, lagoons, and fishing villages that the highway bypasses.

Days 18–21: Ho Chi Minh City and the Mekong Delta

HCMC is intense, fast, and genuinely different from Hanoi. Give it two full days plus a Mekong day trip.

Ho Chi Minh City is a city of 9 million people and approximately 9 million motorbikes, and the traffic is the experience before the sights. Crossing the street requires commitment: step off the kerb, walk steadily, don't stop, let the traffic flow around you. It works.

The War Remnants Museum (€2 entry) is a mandatory stop — three floors of Vietnamese documentation of the American War (as it's known here), including Agent Orange photography that requires emotional preparation. It's not neutral in its framing and it's important. The Cu Chi Tunnels (40km northwest of HCMC, €5 entry, most easily accessed by half-day tour for €10–15 including transport) are the network of underground tunnels used by Viet Cong fighters — some of the crawl spaces are available to enter, the history is extraordinary.

The Mekong Delta day trip from HCMC covers the river, floating markets, and riverside villages in a day (guided tours from €20–30). The genuine Mekong experience requires two or three days in Can Tho, the delta's largest city — a worthwhile extension if your schedule allows.

Budget reality: Vietnam remains genuinely affordable. A mid-range three-week trip — comfortable guesthouses, sit-down restaurant meals, overnight trains rather than flying every leg — runs €50–70 per person per day. Budget travel (hostels, street food, local transport throughout) runs €30–40. Flying every internal leg and staying in boutique hotels: €100–120.

This is exactly the kind of research rabbit hole that Budge was built for — you can ask it follow-up questions about any of this and it remembers what you care about across the whole conversation.

The honest truth about Vietnam's transit reality

Vietnam is long and most travellers don't appreciate how much travel time the north-to-south route involves until they're in it.

Hanoi to HCMC direct by train is 35+ hours. By road it's longer. Even flying every leg — Hanoi to Ha Long (no direct flight, overland), Ha Long to Hoi An (fly via Da Nang, 2 hours), Hoi An to HCMC (fly, 1h 20min) — involves airport logistics that consume half-days. The itinerary above explicitly builds in one transit day for every five sightseeing days; most generic Vietnam itineraries don't and produce a trip where travellers arrive at beautiful places too tired to experience them properly.

Budget the transit time honestly. The overnight train is a feature when you're rested; it's a misery when you're already tired. Fly when the journey is over 8 hours. Take the train when the journey is the experience.
