Situated in Mawsynram – known as the wettest place on earth, the Mawjymbuin Cave is a natural wonder that carries immense religious significance. The 209-metre high cave, also known as Krem Mawjymbuin, astonishes every visitor. Mawjymbuin cave is formed in calcareous sandstone. Especially impressive is the entrance chamber, which is only 4 m high at the centre but up to 50 m wide. Well visible in the centre of this hall is a pair of stalactite and approximately 1 m tall stalagmite below it which appears like the Shiva Lingam. At the east wall of entrance chamber runs a small stream, which leads into side passage, after some 40 m ending in boulders. There are several more side passages.

The impressive pair of cave formations has turned this cave into a sacred shrine for Hindu and flocks of religious tourists are appearing here. Tourism authorities hope to get more profit out of it and even want to rename the cave into Shiva Linga Cave.
