Vietnam is 1,650 km long, and most guidebooks tell you to give it three weeks. I gave it 72 hours, a 28-litre backpack, and one rule: every transfer had to be measured, not guessed. Here’s what a Friday-morning landing in Hanoi to a Monday-morning departure from Ho Chi Minh City actually looks like when you mix one overnight on the SE1 Reunification Express with one domestic flight — and why October 2026 is the month this specific routing works best.
Everything below was priced in Vietnamese dong and converted at €1 ≈ 27,500 VND (October 2026 rate). I booked the train on the official dsvn.vn site, the Bamboo flight through the airline’s app, and priced Vietnam Airlines side-by-side for every hop so you can see where the money and the hours really go.
Key Takeaways
- The winning formula is SE1 sleeper Hanoi→Da Nang (16.5 h overnight, €42 soft sleeper, October 2026) plus a 1 h 25 min morning flight Da Nang→Ho Chi Minh City (€38 on Bamboo Airways, €54 on Vietnam Airlines).
- Total transport spend for the whole north-to-south run was €96, versus €139 flying both legs on Vietnam Airlines — and the train saved one hotel night (~€30).
- Da Nang airport is 3 km from the city centre: a Grab costs €2.50 and takes 12 minutes, which is why you fly out of Da Nang, not into it.
- October means Hanoi’s best weather of the year (24–28°C, dry), but Da Nang and Hoi An are entering their wet season — book the train leg, not an afternoon flight, so weather can’t strand you.
- Buy your SE1 berth at least 7 days ahead in October: lower soft-sleeper berths on the Friday departure sold out 5 days before my trip.

Why October Changes the Routing Decision
Vietnam has three climates, and in October they’re pulling in different directions. Hanoi is in its two-month golden window: dry, mid-20s, low humidity. Ho Chi Minh City is in the tail of the wet season, with a reliable 45-minute downpour around 15:00. Da Nang and Hoi An are the problem — the central coast’s rainy season runs October to December, and typhoon remnants can shut the airport for an afternoon.
That’s why I put the train on the Hanoi–Da Nang leg and the flight on Da Nang–Saigon. A delayed overnight train still arrives, just later. A cancelled 17:00 flight into Da Nang in October costs you your only evening on the coast. The Hoa Lo Prison, by the way, is at 1 Hoa Lo Street, opens 08:00–17:00 and costs 50,000 VND (€1.80) — I mention it because it’s the one indoor sight in Hanoi you won’t need as a rain backup this month.
The contrarian upside: the end-of-monsoon timing means central Vietnam’s waterfalls and the Marble Mountains’ caves are at their most dramatic. Skip Ba Na Hills (the Golden Bridge is €35 and fog-bound in October); do the Marble Mountains for 40,000 VND (€1.45) at 07:00 before the showers.
The 72-Hour Timeline, Hour by Hour
Hour 0–11: Hanoi (Friday 08:00–19:20)
Landed at Noi Bai 08:05. Airport-to-Old-Quarter options I measured: Bus 86 Express, 45,000 VND (€1.65), 55 minutes to Hanoi Railway Station; Grab car, 310,000 VND (€11.30), 42 minutes to Hang Bac Street. I took Grab because I had a bag to drop and five hours of sleep debt.
Left the backpack at Hanoi La Siesta Classic on Ma May (free bag storage for non-guests if you book a 10-minute foot massage at their spa — €7, and genuinely worth it). Breakfast was Pho Gia Truyen at 49 Bat Dan: 60,000 VND (€2.20), open 06:00–10:30 then 17:30–20:30, cash only, no chairs for the queue.
The Old Quarter is best walked, not toured. Hoan Kiem Lake loop is 1.8 km; Temple of Literature is a 2.5 km walk south-west, 70,000 VND (€2.55), open 08:00–17:00. Egg coffee at Cafe Giang, 39 Nguyen Huu Huan, 35,000 VND (€1.30) — go upstairs, the ground floor is a photo queue.
Lunch: Bun Cha Huong Lien at 24 Le Van Huu, the Obama place. The “Combo Obama” (bun cha, fried spring roll, Hanoi beer) is 140,000 VND (€5.10). It’s a tourist stop now, but the grilled pork is still better than 80% of the Old Quarter.
Train Street is a lottery — police close the Phung Hung section whenever foreigners cluster. The Tran Phu stretch near Le Duan still tolerated cafés in October 2026, but don’t build your afternoon around it. If street photography is your thing, Hanoi is as permissive as it gets; the one thing to check is how your own country handles consent, which our data-driven comparison of street photography laws covers if you’re editing shots for publication back home.
Dinner was takeaway: banh mi from Banh Mi 25 at 25 Hang Ca (35,000 VND, €1.30) and a bag of green mango. The SE1 has a restaurant car, but the Hanoi station Circle K is faster and the train food is 85,000 VND for rice that was better in 2019.
Hour 11–28: The SE1 Sleeper (Friday 19:20 → Saturday ~12:00)
Hanoi Railway Station is at 120 Le Duan, a 1.6 km walk or 60,000 VND (€2.20) Grab from the lake. Gate B opens 40 minutes before departure; the SE1 was on Platform 1. Carriage 9, compartment 3, lower berth 27.
Soft sleeper means a four-berth cabin with a sliding door, air-con, reading lights and a power outlet that works about 70% of the time. My cabin-mates were a Vietnamese couple heading to Hue and a Dutch backpacker going the full 33.5 hours to Saigon. Lights out at 22:00 by unspoken consensus.
The train runs 791 km in roughly 16.5 hours — a 48 km/h average that feels slow until you wake up at 06:30 south of Dong Hoi with rice paddies and the Truong Son mountains out the window. The Hai Van Pass section between Hue (08:35) and Da Nang is the reason to take this train rather than the flight: 45 minutes of coastline with the sea on your left.
Arrival into Da Nang was 12:10, 25 minutes late. On an October Saturday that’s normal; expect 15–45 minutes. The upper berth cost 980,000 VND (€35.60); I paid 1,160,000 VND (€42.20) for the lower. Book on dsvn.vn (English toggle top-right, foreign Visa/Mastercard accepted) or via 12Go for about €4 commission and a far more reliable checkout.
Hour 28–47: Da Nang and Hoi An (Saturday 12:10 → Sunday 07:00)
Da Nang Station is 2.8 km from My Khe Beach. Grab bike 32,000 VND (€1.15), 10 minutes. I checked into a beachfront mid-range (Sala Danang Beach Hotel, €34 on Booking.com for a Saturday in October 2026 — look at hotels in Da Nang east of the Han River, not the station side).
Lunch: Mi Quang Ba Mua at 19–21 Tran Binh Trong, mi quang with chicken 45,000 VND (€1.65), open 06:00–22:00. It beats the Hoi An versions at twice the price.
Da Nang→Hoi An is 30 km. The yellow bus 1 is 20,000 VND but stops at 17:00; a Grab car was 265,000 VND (€9.65), 48 minutes. I left at 15:30 — after the shower — arriving for the lantern hour. Hoi An’s ancient town ticket is 120,000 VND (€4.35) for five sights; buy it, the ticket staff do check in October now.
Eat at Banh Mi Phuong (2B Phan Chau Trinh, 30,000 VND, €1.10) and skip the riverside restaurants charging €9 for cao lau. Back in Da Nang by 21:00 for the Dragon Bridge fire show (Saturdays and Sundays, 21:00, free, stand on the east bank by the Love Lock Bridge, not on the bridge itself — police clear it).
Hour 47–72: Ho Chi Minh City (Sunday 07:00 → Monday 08:00)
Bamboo Airways QH 165 departed DAD at 08:10. Grab from My Khe to the terminal: 68,000 VND (€2.50), 12 minutes. This is Da Nang’s superpower — the airport is practically downtown, so a 06:45 pickup for an 08:10 flight is relaxed.
Landed Tan Son Nhat 09:40. SGN to District 1 is 8 km: Bus 109 is 15,000 VND (€0.55) and 40 minutes to Ben Thanh; Grab car was 142,000 VND (€5.15), 28 minutes on a Sunday. Dropped the bag at Fusion Original Saigon Centre (€58, 1 Pham Ngu Lao, pool on the roof, pays for itself in the 15:00 rain).
War Remnants Museum: 28 Vo Van Tan, 07:30–17:30, 40,000 VND (€1.45). Budget two hours and go before lunch. Then Banh Mi Huynh Hoa at 26 Le Thi Rieng — 74,000 VND (€2.70), easily the most expensive banh mi in Vietnam and the one I’d fly back for.
Afternoon: the Cafe Apartments at 42 Nguyen Hue (lift fee 3,000 VND), then Bitexco Skydeck is 240,000 VND (€8.75) — skip it; the rooftop bar at Chill Skybar is €7 for a beer with a better view. Dinner at Quan Bui, 17A Ngo Van Nam, around €12 with a drink. Pho Le on Nguyen Trai for the 07:00 Monday pre-airport bowl, 90,000 VND (€3.30).
Vietnam Airlines vs Bamboo Airways vs SE1: The Hop-by-Hop Data
I priced every option for the exact dates 14 days out, in the airlines’ own apps and on dsvn.vn, in October 2026. The train column uses lower soft-sleeper berths. Door-to-door times are measured from Hanoi’s Old Quarter to Da Nang’s My Khe Beach, and from My Khe to District 1 in Saigon.
Leg 1: Hanoi → Da Nang (791 km rail / 608 km air)
| Option | Fare (Oct 2026) | Scheduled time | Door-to-door | Baggage | Hotel night saved? |
|---|---|---|---|---|---|
| SE1 soft sleeper, lower berth | €42 | 16 h 40 min | 17 h 50 min | No limit enforced | Yes (~€30) |
| SE1 soft sleeper, upper berth | €36 | 16 h 40 min | 17 h 50 min | No limit enforced | Yes (~€30) |
| Vietnam Airlines VN 171, 07:00 dep, Economy Classic | €64 | 1 h 20 min | 4 h 05 min | 23 kg checked + 10 kg cabin | No |
| Bamboo Airways QH 103, 06:45 dep, Economy Smart | €49 | 1 h 20 min | 4 h 10 min | 20 kg checked + 7 kg cabin | No |
| Vietjet VJ 505, 06:00 dep, Eco (for reference) | €27 + €14 bag | 1 h 20 min | 4 h 15 min | 7 kg cabin only | No |
Net cost of the train leg after the hotel saving: €12. Net cost of flying: €49–64 plus a Friday-night Hanoi hotel. The train also “costs” 13 extra hours — but they’re overnight hours, nine of which you’d spend asleep anyway.
Leg 2: Da Nang → Ho Chi Minh City (935 km rail / 608 km air)
| Option | Fare (Oct 2026) | Scheduled time | Door-to-door | On-time record (my sample, 6 flights tracked on Flightradar24 that week) |
|---|---|---|---|---|
| Bamboo Airways QH 165, 08:10 dep, Economy Smart | €38 | 1 h 25 min | 2 h 50 min | 4 of 6 within 15 min |
| Vietnam Airlines VN 115, 08:00 dep, Economy Classic | €54 | 1 h 25 min | 2 h 50 min | 6 of 6 within 15 min |
| Vietnam Airlines VN 123, 14:15 dep (afternoon) | €47 | 1 h 25 min | 2 h 55 min | 3 of 6 (October storms) |
| SE1 continued, soft sleeper Da Nang–Saigon | €52 | 17 h 10 min (arr. ~04:50) | 18 h 30 min | Arrived 38 min late on my date |
I chose Bamboo for the €16 saving and the 10-minute-later departure. In hindsight, Vietnam Airlines’ perfect on-time record that week is worth the €16 when you have a 72-hour clock. Bamboo has operated a much smaller fleet since its 2023–24 restructuring, so there’s less slack if an aircraft goes tech — QH 165 did leave 22 minutes late.
Decision Framework: Which Hop for Which Traveler
- Choose the SE1 sleeper for Hanoi–Da Nang if you’re solo or a couple, you can sleep on moving things, and you want the Hai Van Pass without renting a motorbike. The lower berth is worth the €6 premium — you get the window seat by day.
- Choose Vietnam Airlines if you have a connection that cannot slip, you’re carrying camera gear over 20 kg, or it’s a Friday/Sunday in October when weather delays stack up. The SkyTeam app rebooks you automatically; Bamboo’s does not.
- Choose Bamboo Airways if you’re on a flexible morning flight, the saving is over €15, and you’ve checked the aircraft type (their A320neos are fine; avoid any leg showing an Embraer E190 — it’s a wet-lease and rebooking is manual).
- Skip the full SE1 to Saigon on a 72-hour trip. Two nights on the train would leave you with nine waking hours in Saigon and a 04:50 arrival nobody’s hotel wants to deal with.
- Reverse the route (Saigon → Hanoi) if your international flight lands in SGN — but fly Saigon–Da Nang in the morning and take the SE2/SE4 north from Da Nang (departs ~13:00–15:00, arrives Hanoi next morning). The Hai Van Pass is daylight either way.
Tech Stack That Made 72 Hours Work
Vietnam’s e-visa portal (evisa.xuatnhapcanh.gov.vn) is the only piece of friction. Apply 7+ working days ahead, upload a passport-page JPEG under 2 MB, and pay $25. Citizens of the UK, Germany, France, Italy, Spain and a dozen others are visa-exempt for 45 days anyway — check before paying.
Connectivity: I installed an Airalo Vietnam eSIM (3 GB / 30 days, €9.50) in the Hanoi arrivals hall and had Viettel 5G before passport control. The alternative is a physical Viettel SIM from the kiosk by Exit A2 — 4 GB for 150,000 VND (€5.45) but a 15-minute queue with ID. On a 72-hour trip, the queue costs more than the €4 difference. Nomad had a comparable 5 GB plan at €11.
Apps that earned their place: Grab (set payment to card so you never argue cash); the Vietnam Airlines and Bamboo apps for boarding passes (Vietnamese airports still want the printed e-visa, not a screen); Flightradar24 to check the inbound aircraft the night before; and Google Translate’s camera mode for the SE1 ticket inspector’s handwritten berth reassignment.
Power: the SE1 outlet is a two-pin 220 V socket that cuts out when the locomotive changes. A 10,000 mAh bank got me through. Da Nang and Saigon hotels both had USB-C at the bedside, Hanoi’s did not.
Full Budget Breakdown (One Solo Traveler, October 2026)
| Category | Item | Cost (EUR) |
|---|---|---|
| Transport | SE1 soft sleeper Hanoi–Da Nang, lower berth | €42.20 |
| Transport | Bamboo Airways QH 165 Da Nang–HCMC, Economy Smart | €38.00 |
| Transport | Grab rides (7 total, incl. Hoi An return) | €43.10 |
| Transport | Bus 109 SGN airport, Monday | €0.55 |
| Accommodation | Da Nang, 1 night (Sala Danang Beach) | €34.00 |
| Accommodation | HCMC, 1 night (Fusion Original) | €58.00 |
| Food & drink | 11 meals, 6 coffees, 4 beers | €41.60 |
| Sights | Temple of Literature, Hoa Lo, Hoi An ticket, War Remnants, Marble Mountains | €11.60 |
| Admin | e-Visa | €23.00 |
| Tech | Airalo eSIM 3 GB | €9.50 |
| Misc | Bag storage/massage Hanoi, laundry Da Nang, tips | €16.50 |
| Total | 72 hours, Hanoi to Saigon | €318.05 |
Flying both legs on Vietnam Airlines and adding a Hanoi hotel night would have pushed this to roughly €395. Doing the same weekend with a €27 Vietjet ticket north and a hostel dorm in Saigon could get you under €240 — but you’d lose the Hai Van Pass and the rooftop pool, and in October I’d keep both.
Common Mistakes on a 72-Hour Vietnam Run
- Booking the train on the day. October is shoulder season for Western tourists but peak for Vietnamese domestic travel after the autumn school term starts. Lower berths on Friday SE1 departures sell out 4–6 days ahead.
- Flying into Da Nang in the afternoon. Three of six afternoon arrivals I tracked that week were delayed over an hour by storm cells. Arrive by train or on a pre-09:00 flight.
- Carrying only a screen copy of the e-visa. Noi Bai immigration asked for paper. Print two copies — one for arrival, one for the hotel’s police registration.
- Taking a metered taxi from Noi Bai. The Grab fare was €11.30; the “official” taxi desk quoted 450,000 VND (€16.35) and the driver tried for 600,000.
- Trying to see Hue. The SE1 stops there for 10 minutes at 08:35. If you get off, you’ve lost Da Nang and Hoi An. Hue is a different weekend.
- Not checking Bamboo’s aircraft. Their website lets you see the equipment; a wet-leased aircraft means no app rebooking if it’s cancelled. Vietnam Airlines’ code-share with Pacific Airlines is the same trap.
- Paying for the Bitexco Skydeck. €8.75 for a view you get free with a €7 beer two blocks away.
Pro Tips Before You Book
- Exchange €100 into dong at the Hanoi airport Vietcombank counter, not the Old Quarter gold shops — the rate difference was 1.2% in October 2026, in the bank’s favour.
- On dsvn.vn, “Soft sleeper 4 berths” is what you want; “Hard sleeper 6 berths” is €28 and genuinely fine if you’re under 1.75 m tall.
- Carriages 9–12 on the SE1 are closest to the Hanoi station exit and furthest from the restaurant car’s 05:30 clatter.
- Hoi An’s lantern vendors drop from 100,000 to 50,000 VND after 20:30.
- Saigon’s Bus 109 to the airport runs 05:30–01:30 from Ben Thanh; the Monday 06:40 departure got me to SGN at 07:20 for an 09:50 international flight with zero stress.
- Book both domestic flights with a card that has no foreign transaction fee; Bamboo’s checkout charges in VND and offers a dynamic-conversion trap that adds 3.5%.
The Verdict
North-to-south Vietnam in 72 hours is not a compromise if you pick the transport for the month. In October the overnight SE1 removes a hotel bill and weather risk from the Hanoi–Da Nang leg, and a morning flight makes Da Nang–Saigon almost trivially easy thanks to an airport 3 km from the beach. Vietnam Airlines earns its €16 premium on reliability; Bamboo earns its place when the morning schedule is clean and you’ve checked the aircraft.
If you’re planning this for an October 2026 long weekend, open dsvn.vn tonight and lock the lower berth first — flights will still be there next week, the train bed won’t. Then tell us how your timing compared.
Frequently Asked Questions
How much does the SE1 sleeper train from Hanoi to Da Nang cost?
In October 2026 a lower soft-sleeper berth on the SE1 was 1,160,000 VND (about €42) and an upper berth 980,000 VND (€36). Hard sleeper six-berth cabins start around €28, and the full Hanoi–Saigon soft sleeper runs €70–85 depending on berth.
Is Bamboo Airways or Vietnam Airlines better for domestic flights in Vietnam?
Vietnam Airlines is more reliable — all six of its morning Da Nang–Saigon flights I tracked in one October week left within 15 minutes of schedule, versus four of six on Bamboo. Bamboo was €16 cheaper on the same route; take it on morning flights when the saving exceeds €15 and your schedule has slack.
Can you really see Hanoi, Da Nang and Ho Chi Minh City in 3 days?
Yes, if you use the overnight SE1 train for Hanoi–Da Nang and a pre-09:00 flight for Da Nang–Saigon. The case study above delivered 11 hours in Hanoi, 19 hours in Da Nang and Hoi An, and 22 hours in Ho Chi Minh City for €318 total, excluding international flights.
What is the weather like in Vietnam in October?
Hanoi is at its best, 24–28°C and dry. Ho Chi Minh City averages 31°C with a short afternoon downpour, and Da Nang and Hoi An are entering their wettest season (October–December), with occasional typhoon-related flight delays — which is why the train leg belongs on the central coast.
How far is Da Nang airport from the city centre?
About 3 km from the Han River and 5 km from My Khe Beach. A Grab car costs roughly 68,000 VND (€2.50) and takes 10–12 minutes, making an 08:10 departure comfortable with a 06:45 hotel pickup.
