Cruise Tour of Route 4 – Explore the Pristine Beauty of Bai Tu Long Bay
1. Where is Bai Tu Long Bay?
Bai Tu Long Bay is located adjacent to Halong Bay, a UNESCO World Heritage site. Sharing a similar landscape with Halong Bay, Bai Tu Long boasts hundreds of small and large islands rising from the emerald waters, creating a stunning watercolor painting. However, compared to Halong Bay, Bai Tu Long has a more pristine and tranquil beauty, largely untouched by mass tourism development.
Bai Tu Long Bay stretches from Ha Long City to Cam Pha City and Van Don Island District, including Co To Island. This area is not only attractive for its majestic limestone islands and cliffs but also for its diverse ecosystem, featuring smooth white sandy beaches, pristine forests, and fishing villages. Here, visitors can engage in many exciting activities such as kayaking, exploring caves, or enjoying the fresh air on untouched beaches. Bai Tu Long Bay is truly a hidden gem, an ideal choice for those seeking tranquility and closeness to nature.

2. Differences Between Halong Bay and Bai Tu Long Bay
While Halong Bay is famous for attractions like Sung Sot Cave, Ti Top Island, and bustling tourist spots, Bai Tu Long Bay offers a completely different experience. With fewer tourist boats and a more untouched landscape, Bai Tu Long allows visitors to enjoy a more private and peaceful atmosphere. It is the perfect place to immerse yourself in nature and appreciate the beauty of the islands and clear waters without interruptions.
