From the beaches and nightlife of Nha Trang you head north along the spine of Vietnam to Dong Hoi, the gateway to Phong Nha-Ke Bang National Park and its caves. The route passes salt pans, rice paddies and the Annamite foothills, and you can ride the Reunification Express or take an overnight sleeper bus.
Nha Trang to Dong Hoi by Train
Nha Trang and Dong Hoi are both stops on the North-South railway line.[1] This is a full day or a full night on the rails, but the train lets you walk the carriages, visit the food trolley and stretch out in a berth, which a bus cannot match.
Sleeper Cabins and Comfort Classes
Sleeper berths are the popular choice for this distance. The 4-bed compartments give a good balance of privacy and space, the 6-bed compartments cost less, and the VIP cabin for two is the most private. Hard and soft seats suit shorter hops better than this long ride. A lower berth is easier to reach and keeps your luggage close.
Nha Trang to Dong Hoi by Bus
The overnight bus runs point to point and takes from about 12.5 hours. On booking platforms, tickets cost about $77 to $86 (November 2026).[2] You can choose between the Sleeper 40, with three rows of bunks, and the Limousine 32 with onboard toilet, which has fewer seats and more space.

Tips for Traveling from Nha Trang to Dong Hoi
- Book in Advance: Sleeper berths on trains, especially lower berths and 4-bed compartments, sell out days ahead in the peak season.
- Pack Snacks: Trains have a food trolley and buses stop for breaks, but the choice is small. Bring water, fruit and snacks for the night.
- Prepare for the AC: Trains and buses are cold inside. Keep a light jacket or hoodie handy.
- Luggage Safety: On the train, keep valuables in a small bag in your berth. On the bus, lock and label the suitcase that goes in the hold.
- Arrival in Dong Hoi: Phong Nha Cave lies about 50 km from Dong Hoi,[3] so arrange a taxi or a local bus from the city.
