Kiliyur Falls is a waterfall in the Shervaroyan hill range in the Eastern Ghats, Tamil nadu, India. The waters overflowing the Yercaud Lake fall 300 ft (91 m) into the Kiliyur Valley.
The falls is situated at a distance of 2.5 km (1.6 mi) from the yercaud lake. The final 500 m (1,600 ft) or so consist only of a rough unpaved steep pathway. But it is a breathtaking sight in the monsoon time when the water levels are at the maximum. The best time to visit this place is immediately after the monsoons.
