SHILLONG: India's 10th longest cave and the 9th longest limestone cave, Lungchung Khur measuring 13,618 meters, has been discovered in Meghalaya’s vast underground network.
The ancient structure was discovered during the Caving in the Abode of the Clouds Expedition 2025 held from February 2 to 28. The expedition was conducted by the Meghalaya Adventurers Association (MAA) in collaboration with an international team of cavers.
22,663 meters of previously unexplored cave passages were successfully mapped during the expedition which focused on the limestone cave systems of Byrong, Jongria, and the Muallian Spur.
Lungchung Khur is located beneath the Muallian Spur and it contains massive underground river passages. The width and height of some of these passages is measured at 30 meters and it is characterized by intricate relic formations and boulder chokes.
Explorers found eight caves in the Byrong area of Wahlong in East Khasi Hills, leading to the uncovering of 6,210 meters of new cave passages. Krem Riblai (1,973 meters), Krem Khla (1,521 meters), and Krem Wallang (1,393 meters) were among the significant findings.
Further exploration in Jongria village led to the unveiling of 27 caves in the Pongkoloi River region, also known as the Khangban River Valley, and the Litang Basin.
Canyon Sink (938 meters), Lizard Splat, Honeycomb caves, and the Krem Soh Shrieh System also happened to be some of the other notable discoveries. These significant findings resulted in the revelation of 13 newly discovered blind shafts with a depth of 8 to 26 meters.
