Mo Luong Cave lies inside Pu Kha Mountain in Mai Chau town and Chieng Chau commune, Mai Chau district. The main entrance to the cave is in Mai Chau town and the subordinate entrance 

is along the water current in Chieng Chau commune. In the Thai language, Mo Luong means big course of stream;

that is the course that originates from inside the cave running out to the field in the Chieng Chau direction and where people dug a pond to retain water and thus named it Mo Luong Pond.
