Being 170 km east of Hanoi capital, Halong Bay is easily accessible from Hanoi center by shuttle bus, but from Noi Bai airport to Halong city (Tuần Chau Marina) is only by private transfer. So you should book in advance a private car to Halong Bay.
Private car pick up from Noi Bai airport including free flight tracking and an hour waiting time, ensuring you plenty of time to get through the airport before meeting your driver then transfer to Ha Long Bay. On a half way, you can have a short break 20-30 minute. After 3.5 hours you will arrive in Halong city and we drop you off at your desired place as Tuan Chau port or Hon Gai port
