Puong Cave
Động Puông
A giant limestone cave through which the Nang River flows, about 300 metres long and over 30 metres high. Boats pass through the cave, and countless bats roost on the ceiling.
Puong Cave lies on the upper reaches of the Nang River above Ba Be Lake. The river flows straight through a limestone mountain, forming a tunnel about 300 metres long and more than 30 metres high. Stalactites hang inside, and thousands of bats roost on the cave ceiling. Tour boats enter the cave along the Nang River and move slowly through, the highlight of the Ba Be Lake boat route. The interior is dim, the smell of bat droppings is strong, and dripping water from above is common. It is usually included in the tour boat itinerary around the lake.
