When Cam Ranh Bay used to be an important naval base, Nha Trang Airport was the main airport of the city. This airport was used by the United States Air Force and South Vietnam Air Force during the Vietnam War. When part of Cam Ranh Bay was made an economic development zone by the Vietnamese government, Cam Ranh International Airport (also a military airport built by the United States during Vietnam War) was made the new civilian airport of the city. This airport is located by Cam Ranh Bay, 45 km (28 mi) south of the city and is currently (as of 2007) the forth busiest airport in terms of passenger traffic in Vietnam serving more than 683.000 passengers in 2008.
The city is located next to the National Road 1A, the backbone north-south road of the country. The Reunification Railway also crosses the city and stops at Nha Trang Railway Station. The construction work of Van Phong Port, north of the city, a deep-water project capable of handling ships up to 100,000 tonnes, and with a capacity of 100 million tonnes of cargo per annum, is under progress by a consortium of Japanese corporations. The estimated investment capital for this port-city complex project is expected to reach US$15 billion.
Lien Tinh bus station is Nha Trang’s main intercity bus terminal, 500m west of the train station. Seven daily buses head north to Quy Nhon (5½ hours), with at least two continuing to Danang. Regular buses head south to Phan Rang (2½ hours), with a dozen continuing on to HCMC (11 hours) and a similar amount heading into the highlands to Dalat (seven hours).
Nha Trang is a major stopping point on all of the tourist open-bus tours. These are the best option for accessing Mui Ne, which is not served by local buses. Sinh Café runs a comfortable coach at 7.30am, reaching Ca Na before 11am and Mui Ne just after midday. It stops here for lunch before continuing on to HCMC (arriving 5.30pm). It also runs services to Dalat (six hours) and Hoi An (11 hours).
