The World’s Largest Cave passage was discovered deep within a remote Vietnamese jungle. The Son Doong cave measures 262 feet by 262 feet (80 meters by 80 meters) and at least 2.8 miles (4.5 kilometers) deep, making it the largest single cave passage ever discovered, according to National Geographic News, where the discovery was announced.
The previous record holder, Deer Cave in Malaysia, is 300 feet by 300 feet (91 m by 91 m) in parts, but is only about a mile (1.6 km) long.
