While Halong Bay is one of Vietnam’s most iconic destinations, attracting millions of visitors every year.. However, as the popularity of the bay continues to grow, many tourists are now seeking quieter alternatives to escape the crowds and explore the untouched beauty of this natural wonder. This is where Cruise Route 4 comes in, offering a journey into the lesser-known Bai Tu Long Bay, a pristine area that promises a more authentic experience.
In this blog, we’ll guide you through everything you need to know about Halong Bay Cruise Route 4, from its itinerary and highlights and experiences it offers.
Halong Bay Cruise on Route 4
Halong Bay is divided into five main cruising routes, as designated by the Halong Bay Management Board. While Routes 1, 2, and 3 focus on the central areas of Halong Bay, featuring its most famous attractions such as Sung Sot Cave and Titop Island, Route 4 takes you off the beaten path to explore Bai Tu Long Bay.
Bai Tu Long Bay lies to the northeast of Halong Bay and is known for its unspoiled beauty, serene atmosphere, and fewer tourists. This route is perfect for those who want to avoid the crowds and immerse in the tranquil charm of the bay.
Itinerary Highlights
- Duration: Route 4 offers both day cruises (6–8 hours) and overnight cruises (1 or 2 nights).
- Visiting Attractions: Thien Canh Son Cave (Hang Co), Cong Do Island area, and Vung Vieng Fishing Village, Cong Dam area, Thay Cave, Ban Chan Beach…
- Itinerary Overview: Cruises on this route typically depart from Halong International Cruise Port. From there, you’ll visit Hang Co, sail past the scenic Cong Do area, go kayaking, and explore the floating village of Vung Vieng.

Why Choose Bai Tu Long Bay?
While the central areas of Halong Bay are undeniably beautiful, they can often feel overcrowded, especially during peak travel seasons. Bai Tu Long Bay, on the other hand, offers a much more peaceful and secluded experience.
- Less Crowded: Unlike the main areas of Halong Bay, Bai Tu Long Bay is less visited by mass tourists. There is also only some cruise operators in this area, not as much as in Halong Bay center.
- Untouched Beauty: Bai Tu Long Bay boasts stunning landscapes that are just as breathtaking as Halong Bay’s, but with a more untouched and pristine feel.
- Authentic Local Floating Village: Visiting places like Vung Vieng Fishing Village allows you to learn about the traditional way of life of local fishermen, offering a cultural understanding.
For travelers who want to escape the tourist crowds and discover a hidden side of Halong Bay, Route 4 is the perfect choice.
