World's longest sandstone cave found in Meghalaya
A 24,583-metre-long cave that was discovered in 2016 in Meghalaya has been found to be the world's longest sandstone cave by the Meghalaya Adventurers' Association. Called Krem Puri, it is also the second largest cave in India. It is over 6,000 metres longer than the current world record-holder for the longest sandstone cave, the Cueva Del Saman in Zulia, Venezuela.
