The service, called Coco Bus Tour, has two routes with the first departing from Da Nang airport to the south of the city with 25 stops, while the second route will be put into operation in September 2017 to the north of the hub, from the airport to Son Tra peninsula with about 18 stops.
There are 30 open-top bus services a day, with an interval of 30 minutes between 07h00 and 22h00. The listed price is VND250,000 (about USD10.98) which can be used for either route within 24 hours and allows passengers to hop off and hop on at any stop.
The tour will run free of charge until the end of August 2017, and will offer a 50% discount from September to November 2017.
The project was jointly developed by Empire Group and local car maker Truong Hai. Earlier, in July 2017, the two businesses tested the operation of the 12 buses to serve tourism in the city.
