Getting around

Getting to Ha Long Bay

An expressway leads from Hanoi to Ha Long Bay, about two and a half hours by road, and cruise transfers leave from Tuan Chau and Bai Chay ports, Vietnam's tourism authority says. A second page from the same authority gives the bay as roughly two hours' drive from Hanoi, so expect some variation with traffic.

Choosing a cruise boat

Some agents and independent operators ignore the rules, so Vietnam's tourism authority advises booking Ha Long Bay cruises with reputed companies. Accidents have been caused by overcrowding and poor standards, and some boats have sunk quickly, so UK advice says to weigh up safety standards carefully ahead of any overnight boat trip on the bay. Check with your guide on the boat's safety record, registration and crew certification, and make sure a safety briefing and a life jacket are provided. Canada advises against boarding overloaded vessels.
