The 1,726-kilometre rail line between Hà Nội and Hồ Chí Minh City — officially the SE1 and SE2 express services, colloquially the Reunification Express — is one of the great train journeys of Southeast Asia. It is not fast (the full run takes thirty to forty hours depending on direction), and it is not luxurious by international rail standards. What it is, at its best in the first-class sleeping compartments between Đà Nẵng and Huế, is extraordinary.
The Hải Vân Pass Segment
The most celebrated section is the ninety-minute crossing of the Hải Vân Pass, where the track clings to a mountain shelf above the South China Sea, offering views that have made this journey famous among travellers who have taken it from every continent. The train slows on the curves, the light changes as mist rolls in from the sea, and the carriages rock gently — producing a motion that, combined with the view, is deeply soporific.
The route also passes through Lăng Cô Bay at dawn if you time the southbound journey correctly, arriving at a lagoon scene of such stillness that fellow passengers fall silent without coordination. For a section of the journey between Đà Nẵng and Huế, first-class rail travel costs less than a taxi and offers considerably more.
