Marai Cave is also called Krem Marai by the locals and is a sacred site that has been mentioned in folklore and legends of Meghalaya. About 16 km from the city of Shillong, it is popular among locals who believe that descendants of the Syiems, who ruled the Mylliem and Khyrim kingdoms, came through this cave. The cave has a complex structure as there are countless passages to enter and exit it. Many believe that if you aren't guided, you are likely to get lost.

Marai cave also invites adventure seekers as it provides opportunities for hiking and trekking. The hike takes about 20 minutes and on the climb up to Shillong Peak, visitors can go through lush green landscapes. The best time to visit the cave is from February to October.
