Mitiaro is another island with a raised coral limestone plain. Its internal depression is mainly swamp land about 1 m asl. Therefore, the small village of Mangarei (population 230), lies on the shore line. The surrounding coral limestone plateau, the makatea, is no higher than 10 m asl. As a consequence of this, the caves soon end at a pool, although it is assumed that there is a further continuation below the water table.
On the eastern side of the island, Vai Nauri is a brilliantly clear pool in a large chamber. The water falls from the stalactites like rain.
Vai Tamaroa is an open pool surrounded by cliffs about 10 m high. The cave below the pool is completely submerged.
