Puông Cave, a mesmerizing masterpiece of nature, was formed as the Năng River flows through the heart of the Lung Nham limestone mountain. According to local legend:
“Long ago, the Năng River, originating from Phja En, surged powerfully downstream. Upon reaching the village of Vài, it was blocked by the mighty Puông Mountain, causing flooding that devastated the villages. The Jade Emperor sent Tài Ngào, a giant, to carve through the mountain and release the trapped waters, saving the people. This act created Puông Cave, while the rocks Tài Ngào threw behind him became what we know today as Đầu Đẳng Waterfall.”

From Buốc Lốm Boat Wharf at the gateway of Ba Bể National Park, visitors can sail along the tranquil Năng River for about 1 kilometer to reach Puông Cave. The journey itself is enchanting, with the serene river surrounded by lush scenery.
