It is located about 13 km 8. The cave complex contains many Hindu temples , the most popular of which is a shrine dedicated to the deity Murugan. It is the focal point of the Tamil Hindu festival of Thaipusam in Malaysia.
The complex also hosts a 43 m ft high Murugan statue , one of the largest Murugan statues in the world. The name for the cave complex is derived from the Batu Pahat River which flows nearby.
The caves were used as shelters by the indigenous Temuan people , a tribe of Orang Asli. Thamboosamy , an Indian Tamil trader, promoted the cave complex as a site of Hindu worship. Housing development around the region began in the late 20th century with non-governmental organisations expressing concerns about the over-development. The complex is a mogote with a series of limestone caves , formed more than million years ago.
The speleothems were formed by the action of water falling on the surface percolating through the surface and interacting with the sub-surface, resulting in the dissolution of limestone rocks, resulting in the formation of stalactites and stalagmites.
Stalactites jutting from the ceiling and stalagmites rising from the floor form intricate formations of cave curtains, flowstones , cave pearls , and scallops.
