About Vietnam information, Ho Chi Minh City‘s (Saigon) Tan Son Nhat Airport is Vietnam ‘s busiest international air hub, followed by Hanoi ‘s Noi Bai Airport. A few international flights also serve Danang. Singapore, Hongkong, Bangkok have emerged as the principle embarkation points for Vietnam but it’s still possible to get direct flights from a number of major Asian and European cities and a few American, Australian cities. Departure tax is US$14 in Hanoi and 14 US $ in Saigon, which can be paid in Vietnam Dong or US dollars.
There are currently six border crossings for travellers coming to Vietnam, but more may open soon. All crossing points suffer from heavy policing and often requests for ‘immigration fees’.
Getting to Vietnam
For getting to from China, it’s become very popular to cross the border at Friendship Pass or Dong Dang, 20km (12mi) north of Lang Son in northeast Vietnam , to get to/from Namning. There is a twice-weekly international train between Beijing and Hanoi that stops at Friendship Pass. The other popular border crossing with China is at Lao Cai (near Sapa) in northwest Vietnam, which lies on the railway line between Hanoi and Kunming in China ‘s Yunnan Province. There’s also a seldom used crossing at Mong Cai, Quang Ninh Province.
It’s possible to enter Laos from Lao Bao in north-central Vietnam; there’s an international bus from Danang to Savannakhet ( Laos ). The other crossing is at Keo Nua Pass/Cau Treo, west of Vinh.
The only crossing to Cambodia is via Moc Bai; an international bus links Phnom Penh with Ho Chi Minh City .
