Located within Ba Be National Park, Puong Cave is a magnificent natural geological wonder that captivates visitors with its unique experience of boat cruising through a limestone mountain.

Nestled in the Lung Nham limestone mountain range in the northern sector of Ba Be National Park, the cave features a ceiling over 20 meters high and an average width of 30 meters. Flowing through its 300-meter-long interior is the poetic Nang River.

Inside, the cave is adorned with numerous striking stalactites and stalagmites. It also serves as a natural sanctuary for over 23 bat species, housing tens of thousands of individuals. Visitors can explore the cave by motorboat or kayak, soak in the refreshingly cool air, and capture memorable check-in photos.
