Lan Hạ Bay

Lan Ha Bay is situated approximately 30 km from the center of Hải Phòng city. It lies to the east of Cát Bà Island and serves as a natural link between Cát Bà and Hạ Long Bay. The bay's waters are influenced by the South China Sea and feature a dense cluster of limestone karst formations. It encompasses 139 small sandy beaches, including notable ones such as Áng Vẹm, Cát Dứa, Cát Cò, Bến Bèo, Cô Tiên, Vạn Bôi, and Vạn Hà.^[1][2] The bay's geography supports a rich marine ecosystem, though it faces challenges from tourism and pollution. More than 5,400 hectares of the bay fall under the management of Cát Bà National Park, contributing to its status as a biosphere reserve.^[3]

Lan Ha Bay is a popular destination for eco-tourism, offering activities such as kayaking, boat tours, swimming, and rock climbing. It is often described as a quieter alternative to Hạ Long Bay, with floating villages and opportunities to explore hidden lagoons.^[4][5] Access is typically via boat from Bến Bèo port on Cát Bà Island, with tours ranging from half-day to multi-day cruises on luxury yachts.^[6]

In recent years, the bay has gained international recognition. It was featured in CNN's list of Asia's hidden gems in 2022^[7] and visited by the King and Queen of Belgium in 2025.^[8] However, activities like kayaking were temporarily suspended in 2024 pending new regulations.^[9][10] Interconnections with Hạ Long Bay have been expanded, with new routes linking the two bays for tourism since 2025.^[11][12]
