Bai Tu Long Bay sits to the north-east of Ha Long Bay and is the furthest away from Hai Phong, the main port of departure for those exploring the bays. Because of its more remote setting, Bai Tu Long Bay remains the least explored of the three bays. Similarly to Ha Long Bay and Lan Ha Bay, Bai Tu Long Bay still has the dramatic karst-studded bay but with fewer tourist boats. The craggy islets of Bai Tu Long Bay track the coastline all the way to the Chinese border.

Bai Tu Long Bay is only in its infancy as a tourist destination, but is growing in popularity each year, especially with those seeking an authentic travel experience, away from the crowds. The quiet waters of Bai Tu Long Bay feature the stunning karst formations, fascinating caves and traditional floating villages synonymous with the area.

There are two options for accessing Bai Tu Long Bay, either by boat from Ha Long Bay or Cai Rong, in Van Don Province on the mainland. There are fewer boats to choose from in this area compared to Ha Long or Lan Ha, but there are still a good amount of options to suit different time frames and budgets.

Much like Ha Long Bay, Bai Tu Long Bay can get a little cold during the winter months, especially from December to February. It can also experience storms and typhoons during the summer from August to October which may result in the cancellation of some trips. The summer sees hot and humid weather while the winter is cool and mostly dry with some fog.
