“Hidden beneath the forested hills near Mawsynram, Krem Puri stretches over 24 kilometers of winding sandstone corridors, where fossil-lined walls, echoing chambers, and narrow crawls whisper tales of prehistoric life and geological wonder.”

Krem Puri—meaning “fairy cave” in Khasi—is the world’s longest sandstone cave, hidden deep in the forested hills near Mawsynram, Meghalaya. Spanning over 24 kilometers, this subterranean maze of narrow corridors, fossil-lined walls, and echoing chambers feels like a journey through time. Discovered in 2016, it’s not just a geological marvel but a prehistoric archive, with fossils of marine reptiles like mosasaurs embedded in its sandstone. With its twisting passages and hushed mystery, Krem Puri is a dream for adventurers and a whisper from Earth’s ancient past.
