Best Time to Visit Bai Tu Long National Park: Weather, Activities, Costs & Eco-Tours

Bai Tu Long National Park, nestled within Bai Tu Long Bay in Halong Region, Vietnam, is a pristine UNESCO-recognized biosphere reserve and ASEAN Heritage Garden (designated May 2017). Spanning over 15,783 km², it encompasses more than 40 islands, 6,125 km² of forest, and 9,658 km² of marine waters, showcasing three unique ecosystems: mountain forests, limestone karsts with caves, and vibrant marine habitats. Located 180 km east of Hanoi, the park is less crowded than nearby Halong Bay, offering a serene escape with stunning karsts like Ba Mun, Tra Ngo, and Hon Chinh Islet, pristine beaches like Minh Chau, and cultural gems like Vung Vieng Fishing Village. Home to nearly 2,000 species, including 72 species listed in Vietnam’s Red Book, such as yellow monkeys, chamois, and sea cucumbers, the park is a biodiversity hotspot. Following Vietnam’s administrative restructuring, Ha Long City has transitioned into Halong Region, reinforcing its tourism prominence while emphasizing sustainable travel. Aligned with Quang Ninh’s “Green Tourism” initiative, Bai Tu Long National Park prioritizes eco-friendly exploration through regulated cruises and community-supported tourism.
