Ban Gioc-Detian Falls, Vietnam/China

Ban Gioc-Detian Falls is Asia's largest transnational waterfall, spanning 208 meters wide across a 30-meter main drop—a width 50% greater than #9 Plitvice's widest cascade. Its pastoral setting of limestone karst and working rice paddies offers a quieter spectacle than the tourist-heavy infrastructure of higher-ranked falls, with local farmers visible year-round. The falls generate 1.5 million cubic meters of water per hour during peak season, a flow rate three times that of the average waterfall on this list.
