Vietnam by train: the best stretches, sleeper berths and the Sa Pa line

Ride the stretches, not the whole line

The Vietnam National Authority of Tourism describes a single network of about 2,600 km run by Vietnam Railways, with trains averaging about 40 km an hour. Its own advice is blunt: the train from Hanoi to Ho Chi Minh City can take up to 30 hours, and 16 hours from the central coast to either end is common, so a one- or two-hour domestic flight often makes more sense for the long jumps. The same page notes that much of the track dates from the colonial era and is being renovated, so check before you go.

That does not make the train a bad idea; it means picking where it earns its place. The best stretches are short enough to enjoy by daylight or long enough to replace a hotel night. Hue to Da Nang follows the coast around the Hai Van headland. The Hue to Tho Loc heritage train links Hue with the Phong Nha caves in an afternoon. The Hanoi to Lao Cai sleeper gets you to the mountains for breakfast. And one night between Hanoi and Hue, or Nha Trang and Ho Chi Minh City, turns a travel day into a night's sleep.

One thing the map does not show: the main line does not go to Hoi An. The operator's route list has no station of that name: south of Da Nang the trains call at places such as Tra Kieu, Tam Ky and Quang Ngai, so for Hoi An you leave the train in Da Nang and continue by road.

• Worth it by day: Hue – Da Nang (the HĐ coastal trains), Hue – Tho Loc (HQ1/HQ2 heritage train), Hanoi – Hai Phong (about three hours, according to the tourism board).
• Worth it overnight: Hanoi – Lao Cai for Sa Pa; Hanoi – Dong Hoi or Hue and Nha Trang – Ho Chi Minh City, if you pick an evening departure on dsvn.vn.
• Usually better flown: Hanoi – Da Nang, Da Nang – Ho Chi Minh City, and the full north–south run unless the journey is the point.

The central coast: Hue to Da Nang and the heritage train to Phong Nha

Between Hue and Da Nang the railway runs close to the sea, through forest and tunnels around the Hai Van headland; the tourism board's railway feature describes jungle rising around the train on this stretch. Besides the through SE trains, the operator lists two pairs of local trains, HĐ1/HĐ2 and HĐ3/HĐ4, marketed as "Connecting Central Heritage", with Lang Co as the only intermediate stop. The tourism board says they pause at Lang Co for about ten minutes so passengers can see the bay, and it advises checking the exact timetable on the railway's website, because it changes. From Da Nang station, continue to Hoi An by car.

North of Hue, Vietnam Railways began running a daily heritage train, HQ1/HQ2, in late August 2026. It covers about 189 km between Hue and Tho Loc, which the railway's own booking site calls the gateway to Phong Nha-Ke Bang National Park, with stops at Dong Ha, My Trach and Dong Hoi. When we checked on 2026-10-03, the railway listed HQ2 leaving Hue at 07:15 and arriving at Tho Loc at 11:55, and HQ1 leaving Tho Loc at 13:15 and reaching Hue at 17:25, a journey of 4 hours 10 minutes. The train has swivelling seats, a 24-seat VIP car, a culture car with Hue folk music and a food car serving Hue cakes; tickets are sold on dsvn.vn and on the train's own booking site. The launch offers it advertised differed between its pages, so check the current fare when you book.

This is the stretch where the weather matters most. The UK government's travel advice warns of seasonal flooding in central Vietnam in October and November and of tropical storms along the coast, normally from May to November. If you book a train in those months, keep the following day loose rather than connecting to a flight.

Hanoi to Lao Cai: the night train for Sa Pa

There is no railway to Sa Pa itself. The trains run from Hanoi to Lao Cai, the provincial town by the Chinese border, and the tourism board says overnight trains are the most popular way to make the trip, with transfer vans finishing the journey up the mountain. Its Sa Pa feature describes the night train as about eight hours to Lao Cai, followed by a ride of about an hour to Sa Pa town. The alternative is a limousine van or bus from central Hanoi, which takes five to six hours and drops you in Sa Pa itself.

On the operator's route list, the regular trains are SP3 and SP7 from Hanoi and SP4 and SP8 back, calling at stations such as Yen Bai, Bao Ha and Pho Lu; check the timetable on dsvn.vn for current departure times. The tourism board also mentions private tourist sleeping cars on several key routes. Whichever you choose, the berth is a bed, not a night's sleep in a hotel: plan an easy first morning in Sa Pa.

Read the rules before you buy, because this line has its own. When we checked on 2026-10-03, the operator's 2026 fare policy said an individual Hanoi – Lao Cai ticket can be exchanged only more than 72 hours before departure, for 20,000 dong, and that refunds cost 10% of the fare more than 72 hours ahead, 20% between 24 and 72 hours, 30% between 4 and 24 hours, and are not possible within 4 hours of departure. The same policy offered 15% off a return ticket on trains SP2, SP4 and SP8. If your Sa Pa dates are not fixed, a van is the more flexible booking.

Seats, berths and booking on dsvn.vn

The tourism board lists four classes on the Reunification Express: hard seat, soft seat, hard sleeper and soft sleeper, and suggests soft seats and four-berth cabins for more comfort; four-berth cabins come with simple bedding. It adds that every carriage has Western and squat toilets at both ends. For a night journey, the four-berth soft sleeper is the one to aim for; for a two- or three-hour daytime hop, an air-conditioned soft seat is enough.

Tickets are sold at station counters, through agencies and on the railway's official site, dsvn.vn, which has an English version and its own app. Book in your name as it appears in your passport: when you exchange a ticket at a station, the name on the ticket must match the identity document you show. The tourism board advises buying a few days ahead on ordinary dates and well in advance for holidays, when the faster trains and best berths go first.

Since 15 May 2026, Vietnam Railways says individual tickets paid online can be exchanged on dsvn.vn without going to the station: once per ticket, at least 24 hours before departure, keeping the same passenger and the same stations, with a one-time code sent by text or email. When we checked on 2026-10-03, the general rules (outside Tet, and apart from the Lao Cai and Hai Phong lines) were an exchange fee of 20,000 dong per ticket at least 24 hours before departure, and a refund fee of 10% of the fare at least 24 hours ahead or 20% between 4 and 24 hours ahead, with no refunds within 4 hours. A ticket refunded after an exchange costs 30%. For questions about schedules and refunds, the railway's customer lines are 1900 0109 for the north and 1900 1520 for the south.

The through trains: which ones stop where

The long-distance trains between Hanoi and Saigon carry SE numbers, with odd numbers heading south and even numbers heading north. On the operator's route list they all stop at Vinh, Dong Hoi, Hue, Da Nang, Quang Ngai, Dieu Tri (for Quy Nhon) and Nha Trang, but the smaller stops vary from train to train, so check the station you need before choosing a departure. Shorter trains fill the gaps: SE17 to SE20 between Hanoi and Da Nang, SE21/SE22 between Da Nang and Saigon, SE29/SE30 to Quy Nhon itself, SNT trains to Nha Trang and SPT trains to Phan Thiet for Mui Ne.

In Hanoi the main station is at 120 Le Duan, a short ride from the Old Quarter; in Ho Chi Minh City, Saigon Station is at 1 Nguyen Thong in District 3, according to the tourism board. Over Tet, everything is busier and stricter. Vietnam Railways opened sales on 5 September 2026 for about 300,000 north–south tickets for travel between 23 January and 25 February 2027, with seven pairs of Reunification Express trains a day plus two extra pairs, TN3/4 and TN5/6, and it publishes separate, tougher exchange and refund rules for the holiday period.

• Ninh Binh: a stop on every southbound SE train from Hanoi, useful if you want to skip the road trip.
• Phong Nha: Dong Hoi on the SE trains, or Tho Loc on the HQ heritage train from Hue.
• Hoi An: no station; get off at Da Nang.
• Mui Ne: the SPT trains from Saigon to Phan Thiet, then by road.

Comfort, safety and a luxury option

Overnight trains are safe, but the UK government's travel advice warns of petty theft on trains, particularly while passengers are asleep. Keep your passport, phone and cash on you or under your pillow, and lock the cabin door if you have one. Bring food and water for the evening.

If you want the train for its own sake, The Vietage by Anantara is a private carriage attached to regular trains. Its website describes daily journeys between Da Nang, Quy Nhon and Nha Trang, with six private booths for 12 passengers, meals and drinks included, and sleeper booths on the Quy Nhon to Da Nang journey. It is a different product from a railway berth: book it directly and check what the fare includes.
