Phuong Trang Bus
With over 200 vehicles and routes all over Vietnam, Phuong Trang Bus company (the "big orange bus") is the most reliable choice for bus transport. Vehicles vary, but all are generally well-maintained and clean. Some routes offer seated buses (traditional rows), while (most) others offer double-decker sleeper buses with seats that recline nearly flat. Book online or at a Phuong Trang office and reserve your seats ahead of time. Each bus ride comes with a bottle of water and makes stops at rest stops owned and operated by Phuong Trang. Note: The bus is a good environmental and economical option, but Vietnam roads are often not in the best condition, often increasing travel time.
Choose seats near the front for a smoother ride.
Offices are located in every major city on the routes. Swing by or look online for schedules. Overnight busses are available for long trips.
$5-$15 per person
