Mawsmai cave is situated in the small village of Mawsmai, around four kilometres from Cherrapunjee (Sohra) in the East Khasi Hills district of Meghalaya

The term ‘Mawsmai’ means ‘Oath Stone’ in the Khasi language. The Khasi people use the local term ‘Krem’ for the cave.

The cave is located at an altitude of 1,195 metres above sea level and is indirectly influenced by the streams of the Kynshi river originating from the East Khasi Hills.
