Is there a train to Ha Long?

Not as a visitor service to the harbor. The road is the way.

Hanoi to Ha Long

The bay is a half-day transfer from Hanoi. A through ticket to a boat is smoother than arriving in the city and negotiating at the harbor.

Mode	Time	Notes
Limousine or car	2.5–4 hours	The usual choice. Traffic on the way out of Hanoi decides the hour.
Day tour	12–14 hours	Leaves before dawn and returns at night. Check how many hours are actually on the water.
