Agasthiyar Temple and Falls is situated near the Panateertham, which is 4 km from the
Papanasam Shiva Temple. The falls plummeting down from a height of 100 m, can be reached by trekking 3 kilometers. Buses are available to the temple.
The Agasthiyar temple seems to cling to the rocky mountain above the falls. Legend is that when Lord Shiva married Parvati, he was concerned that the rush of people from the south attending the marriage in the north might result in the northern part sinking, and so he sent Sage Agastya to the south, to this region, in order to balance the world.
The waters that nourish the falls flow through forests filled with medicinal herbs and so are believed to have healing powers.
