Van Long Nature Reserve covers more than 3,500 hectares of wetlands, limestone mountains and surrounding ecosystems. The reserve was established to protect its valuable natural environment and biodiversity and has become one of Ninh Binh’s most distinctive ecotourism destinations. 

The reserve is best explored by traditional rowing boat, allowing visitors to glide quietly across the calm waters surrounded by dramatic limestone formations. Often called the “Bay without Waves,” Van Long is known for its exceptionally still water, which reflects the mountains and sky like a natural mirror. The landscape also includes an extensive cave system, with 32 caves recorded in the reserve; Ca Cave is one of the most notable. 

Van Long is particularly important for wildlife conservation as a habitat for the Delacour’s langur, one of the world’s most endangered primates and a species found only in Vietnam. The reserve also supports diverse birdlife, making it an attractive destination for nature lovers and birdwatchers. 

The landscape changes subtly with the seasons. November to April is a particularly interesting period for birdwatching as migratory birds visit the wetland, while early morning and late afternoon are generally the most atmospheric times for boat trips and wildlife observation. Visitors should keep noise to a minimum and avoid disturbing animals during the experience.

Van Long offers a quieter alternative to the busier boat routes of Trang An and Tam Coc, making it especially suitable for travellers seeking nature, wildlife and peaceful countryside scenery.
