The sleeper bus from Hanoi pulls out of My Dinh station a little after nine at night, and within twenty minutes the driver has already overtaken three trucks on a blind corner while a cassette of Vietnamese pop plays at a volume nobody asked for. You’re lying in a reclined pod, shoes off, knees against the seat in front, somewhere between asleep and alert, watching the lights of the Red River Delta slide past the window. This is how most of Vietnam gets covered by travellers on a budget — not by flying over it, but by lying down across it, one overnight bus or train at a time.
Vietnam rewards exactly this kind of travel. It’s long and narrow, stretched over 1,600 kilometres of coastline, which means the obvious route — Hanoi to Ho Chi Minh City, or the reverse — is also the cheapest and most logical one. You’re never backtracking much, the transport network is dense and competitive, and a full month covering the whole country, food included, can realistically run to $800–1,200 per person. This is a route guide for that journey: where to stop, how to move between stops, and what each place actually costs and feels like.
Hanoi: three or four days in the Old Quarter
Start in the Old Quarter, where streets are still named for the guilds that once worked them — Hang Bac for silver, Hang Ma for paper votives, Hang Gai for silk. Dorm beds here run $5–8 a night; a bowl of bun cha, the grilled pork and noodle dish Hanoi is quietly obsessed with, costs around 40,000–50,000 dong (roughly $1.60–2) from a plastic-stool joint on Hang Manh.
Give yourself a day for the Old Quarter itself, a day for the Temple of Literature and a wander around Hoan Kiem Lake at dawn when the tai chi groups come out, and a day trip to Ha Long Bay or the quieter Lan Ha Bay if you want the limestone karsts without quite so many tour boats. Budget operators run two-day, one-night boat trips from around $60–90, though at that price expect a shared cabin and a fairly fixed itinerary. Hanoi is also where you’ll sort your Vietnam visa confirmation if you haven’t already — most nationalities can apply for an e-visa online in advance, valid for 90 days as of current policy, so check the official Vietnam Immigration Department portal before booking flights rather than relying on secondhand advice from forums.
The reunification railway and the sleeper bus debate
The core north-south artery is the Reunification Express, the rail line connecting Hanoi and Ho Chi Minh City, and it’s worth understanding before you book anything. Soft sleeper berths (four to a cabin, air conditioning, reasonably clean) cost roughly $25–45 depending on distance and season, which is more than a bus but considerably more comfortable, and the views along the Hai Van Pass stretch between Hue and Da Nang are genuinely worth the extra dong.
Sleeper buses, meanwhile, are cheaper and more frequent, and companies like Hanh Cafe and The Sinh Tourist run well-worn backpacker routes with hop-on hop-off tickets that let you break the journey at will. The seats recline almost flat, there’s usually a loo stop every few hours, and the bathroom situation ranges from fine to best not discussed. Neither option is glamorous. Both get the job done.
| Route segment | Train (soft sleeper) | Bus (sleeper) | Approx. time |
|---|---|---|---|
| Hanoi – Hue | $30–40 | $12–18 | 13–14 hrs |
| Hue – Da Nang | $8–12 | $5–8 | 2.5–3 hrs |
| Da Nang – Nha Trang | $25–35 | $12–16 | 10–11 hrs |
| Nha Trang – Ho Chi Minh City | $20–30 | $10–14 | 8–9 hrs |
Hue and the DMZ
Hue, the former imperial capital, sits on the Perfume River and is worth two days minimum — one for the Citadel and Imperial City, with its crumbling gates and reconstructed throne halls, and one for the royal tombs scattered in the hills south of the city, best reached by rented scooter ($5–7 a day) or a shared minibus tour. The food here leans more refined than the north: try bun bo Hue, a spicier, lemongrass-heavy beef noodle soup, or banh khoai, a crispy turmeric pancake folded over pork and bean sprouts, from the stalls around Dong Ba Market.
History-minded travellers sometimes add a day trip to the former Demilitarized Zone north of Hue, visiting the Vinh Moc tunnels or the site of Khe Sanh combat base — sobering, and handled with more nuance by smaller local operators than the big group tours.
Da Nang, Hoi An, and the question of how long to stay
Da Nang itself is a fast-modernising city with a genuinely good beach (My Khe) and not much pull to linger, but 30 minutes south is Hoi An, and this is where most budget itineraries slow down on purpose. The Ancient Town’s lantern-lit streets along the Thu Bon River are a UNESCO World Heritage Site, and while the entry ticket system for the old quarter (around $5–6, covering a handful of heritage houses) catches some visitors off guard, the real draw is cheaper: tailored clothing made in 24–48 hours, a night market strung with silk lanterns, and cao lau, a Hoi An-specific noodle dish using water drawn from a particular well that locals insist can’t be replicated elsewhere.
Three days is a sensible minimum — one for the old town, one for a Basket boat ride through the Cam Thanh coconut forest or a cycle out to Tra Que vegetable village, and one simply to sit by the river. If you’re drawn to coastal stretches with fewer crowds than Vietnam’s headline beaches, it’s worth reading about avoiding overtourism in Southeast Asia before deciding how much time to allocate to the coast versus the interior.
Nha Trang and Da Lat: beach or mountains, not both if you’re tight on time
South of Hoi An, the route splits in spirit even if the road doesn’t. Nha Trang is Vietnam’s package-beach-resort city, heavy with Russian and Korean tour groups, decent diving, and honestly not the most interesting stop on this list unless you want a few flat days by the water. Da Lat, up in the Central Highlands at around 1,500 metres, is the more rewarding detour: a former French hill station with pine forests, strawberry farms, and a climate cool enough that you’ll want a light jacket in the evenings — a genuine novelty after weeks of Vietnamese heat.
Da Lat is also where canyoning trips (abseiling down waterfalls, around $35–45 for a half day) and the Easy Riders motorbike network are based — local guides who’ll take you on their bikes down through the highlands toward the coast over two or three days, sleeping in homestays along the way. It’s one of the more physically engaging ways to cover this stretch of the country, and far removed from a bus seat.
Mui Ne and the final run to Ho Chi Minh City
Mui Ne, a strip of a town between Da Lat and Saigon, gets mixed reviews — the red and white sand dunes are genuinely striking at sunrise, but the town itself has a slightly tired, past-its-prime resort feel. Many budget travellers treat it as a one-night stop to break up the journey south rather than a destination in its own right, and that’s a reasonable call.
Ho Chi Minh City itself is a different register of chaos to Hanoi — louder, faster, more commercial. Base yourself in District 1 or the backpacker cluster around Bui Vien Street for nightlife and cheap dorms ($6–10), or District 3 for a quieter, more residential feel with good coffee shops in converted villas. The War Remnants Museum is essential and difficult viewing; the Cu Chi Tunnels, an hour or two outside the city, are heavily touristed but still worth it for a tangible sense of the scale of the tunnel network used during the war. Eat broken rice (com tam) from any street vendor with a smoking charcoal grill, and don’t leave without a coffee from a sidewalk stool — Vietnamese iced coffee, ca phe sua da, made with condensed milk, is reason enough to linger an extra hour before your flight.
Total costs and timing
A reasonable pace for this route is three to four weeks, allowing two to four nights per major stop rather than racing through. Daily budgets vary by travel style:
| Spending style | Daily budget | What it buys |
|---|---|---|
| Bare bones | $15–20 | Dorm bed, street food, local buses, occasional beer |
| Comfortable budget | $25–35 | Private room in guesthouse, mix of street food and cafes, some tours |
| Flexible | $40–60 | Air-con private rooms, occasional flights to skip long bus legs, dive or trekking add-ons |
Flights between Hanoi and Ho Chi Minh City (or any major stop) run cheap and frequent on Vietjet or Bamboo Airways if time is tighter than money — often $30–50 one way if booked a few weeks out, which can be worth it to skip a single gruelling 20-hour bus leg rather than the whole route.
The Bottom Line
- The north-to-south route works precisely because it’s linear — don’t overthink the direction, just decide whether you want to start in Hanoi’s cooler, more chaotic energy or acclimatise in Ho Chi Minh City’s heat first.
- Mix trains and sleeper buses rather than picking one exclusively; the Hai Van Pass by rail and the Da Lat highlands by motorbike are worth the detour from pure bus-hopping.
- Budget three to four weeks minimum — rushing this route turns every stop into a transit day, and the food alone (different in character every 200 kilometres) deserves slower pacing.
- Build in slack around Hoi An and Da Lat specifically; they reward an extra day far more than Nha Trang or Mui Ne do.
- Vietnam remains genuinely cheap by regional standards, but creeping tourism in Hoi An and Ha Long Bay means booking boat trips and heritage tickets a day or two ahead in high season (December to February, and July–August).
