Why travellers take this route
Most passengers riding the full line to Boten are continuing across the border into China, since Boten is where Lao exit immigration takes place before the short crossing to Mohan.
Booking tips
- If continuing into China the same day, check your onward Chinese train’s timing before booking this leg.
- Given the length of the ride, First or Business class adds worthwhile comfort.
- Consider breaking the journey in Luang Prabang or Vang Vieng rather than riding through in one sitting.
