Da Nang's new bus station is located on Dien Bien Phu after it turns
into Highway 1A. The simplest way to get there from the river is to
take Quang Trang west, which turns into Tran Cao Van, veers left and
meets up with Dien Bien Phu. Take a right and the station is 2.5kms
down on the left. This is where the local spur of the railway line
intersects with Highway 1A just where it takes a sharp elbow turn.
Traffic here is madness, so if you go out to the station by motorbike,
use caution.
The bus station is one of the busiest in Vietnam outside Hanoi and
Saigon. Both the north and the south of the country are serviced from
the same terminal, and there are numerous departures for all domestic
routes from very early morning until late at night. The exception would
be international departures to Laos, but otherwise you don't really
need to book ahead -- just show up and buy a ticket for the next bus.
First and second class fares are available for many routes, and will
buy you a more comfortable, less crowded ride.
