See the buses on 12Go →Where the buses leave from and arrive
In Sapa, buses leave from the companies' offices in town, around Điện Biên Phủ street, often with hotel pick-up; a private car collects you at your hotel.
In Cao Bằng, buses arrive at the bus station or at a company office in town, on Hiền Giang street; Bản Giốc waterfall is about 2 more hours by road.
Sleeper, cabin or limousine?
A sleeper bus has three rows of reclining berths on two levels, the cheapest choice for a night ride. A cabin bus gives each passenger (or couple) a closed pod with a curtain or door, a mattress and a charging socket. A limousine is a 9 to 22-seat van with wide leather seats: faster, fewer stops, often with hotel pick-up, but made for daytime trips.
Booking tips
- Afternoon departures reach Cao Bằng around 4 or 5 am: let your hotel know you will arrive early.
- Travelling as four or five? Sharing a private car narrows the gap with the bus and saves a few hours.
- Bring a light jacket: the air conditioning runs cold all night.
- Shoes come off at the door of sleeper and cabin buses; a bag is handed out for them.
- Keep your passport, phone and cash in a small bag that stays in your berth.
