Bang Hot Spring (Suối nước nóng Bang) in Quảng Bình province, central Vietnam, is a natural geothermal site in the Phong Nha-Kẻ Bàng National Park buffer zone, where sodium-rich thermal water emerges from the ancient limestone karst geology of the most spectacular cave region in the world, home to Son Doong — the world's largest cave. The springs, integrated into a simple resort facility, are positioned in one of the world's most extraordinary natural landscapes — the UNESCO World Heritage-listed Phong Nha karst, with its vast cave systems, underground rivers, and ancient tropical forest. The combination of natural thermal water and access to the world's greatest cave system makes Bang Hot Spring part of one of Southeast Asia's most remarkable adventure tourism destinations.
