The cave walls contain fossilized shells and skeletal remains of marine organisms, confirming the region was once under the ocean.
The cave system is geologically significant for its karst topography, which is actively shaped by the intense rainfall of the Cherrapunji region.
The accessible area is supported by a man-made steel bridge that protects the cave floor from foot traffic erosion.
The cave is part of a larger, mostly unexplored limestone network extending under the plateau.
Arwah Cave is a limestone cave system located in the East Khasi Hills of Meghalaya, known for its visible marine fossils embedded in the cave walls and ceiling. The site features a combination of narrow tunnels and large, naturally illuminated chambers accessible via a well-maintained iron walkway. The pathway traverses through lush jungle terrain before entering the subterranean network. Inside, visitors can observe stalactites and stalagmites formed over geological timescales. The cave is part of the larger Cherrapunji geological landscape, situated near the base of a canyon. Rainwater runoff creates seasonal streams that flow through the deeper sections of the cavern. It provides a distinct glimpse into the region’s prehistoric marine history, as the area was once submerged under the Tethys Sea. The surrounding terrain is characterized by steep limestone cliffs and dense vegetation typical of the Khasi Hills.
The wide entrance platform that captures both the cave mouth and the surrounding jungle canopy.
Wear footwear with high-traction soles as the limestone surfaces can be perpetually damp and slippery.
Bring a portable flashlight, as the interior lighting does not reach all of the fossil-bearing crevices.
Expect high humidity and occasional dripping water, so carry a light rain shell or waterproof casing for cameras.
Attempting to climb off the designated metal walkway, as the limestone floor is uneven and potentially unstable.
Avoid touching the delicate stalactites to prevent oil transfer; do not leave litter in the sensitive subterranean ecosystem.
