In order to contribute to increasing the source of visitors and enhancing the value of heritage exploitation, on March 26, 2026, the People's Committee of Quang Ninh province and the People's Committee of Hai Phong City signed a regulation on coordination in managing the operation of inland waterway vehicles transporting passengers and tourists on Ha Long Bay and Lan Ha Bay. The coordination regulation between the two localities began to be implemented from April 1, 2026.
According to the Coordination Regulations, competent authorities will license tourist ships to transport passengers on 4 connecting routes: Ha Long Bay 3 - Lan Ha Bay; Ha Long Bay 4 - Lan Ha Bay; Ha Long Bay 5 - Lan Ha Bay and Ha Long Bay 6 - Lan Ha Bay.
All of these routes are overnight accommodation ships without organizing day tours, allowing tourists to have more time to experience and fully explore the beauty of two famous bay areas, Ha Long (Quang Ninh province) and Lan Ha (Hai Phong city).
Implementing the Coordination Regulations, on April 20, at Tuan Chau International Passenger Port and Ha Long International Passenger Port, there were 2 tourist boat trips of Bhaya Cruise Co., Ltd. and Asia High-Class Cruise Group JSC organized to serve visitors to Ha Long Bay - Lan Ha Bay. On average, each boat has about 40 guests, mostly international guests.
According to the plan, the two units will maintain the operation of this connecting tour with a fixed daily frequency of operation, contributing to the formation of a stable and long-term inter-regional tourism product.
