Prepare to be awestruck by Ban Gioc Waterfall (Thác Bản Giốc), Vietnam's largest and most spectacular waterfall, located in the northeastern province of Cao Bang, right on the border with China. Straddling the Quay Son River, this magnificent natural wonder is renowned as one of the largest waterfalls in Asia and stands as Cao Bang's premier tourist attraction, drawing visitors with its immense scale and breathtaking beauty.

Fed by the serene Quay Son River, Ban Gioc Waterfall cascades down multiple tiers over a wide ledge, creating a stunning curtain of white water against a backdrop of lush greenery and limestone karst formations. The waterfall is shared between Vietnam and China (where the other side is known as Detian Falls), adding a unique cross-border dimension. Visitors can take bamboo raft trips on the river below to get closer to the thundering cascades, feel the mist, and capture incredible photos.

Visiting Ban Gioc Waterfall is an unforgettable experience, immersing you in the raw power and beauty of nature. The sheer volume of water, especially during the rainy season (approx. June to October), is truly impressive. Often combined with a visit to the nearby Nguom Ngao Cave, exploring Ban Gioc is a highlight of traveling through the Non Nuoc Cao Bang UNESCO Global Geopark and a must-see landmark in Northern Vietnam.
