Agaya Gangai is an enchanting waterfall located in Kolli Malai (Kolli Hills). River Aiyaru, a jungle stream, cascades down as the Agaya Gangai, near Arapaleeswarar temple. Agaya Gangai – as the name implies it indeed is the Ganges of the sky. When we went in December the water flow was quite heavy, but the breeze and saaral (drizzle) was amazing. It is best to visit at beginning of the monsoon just after a few showers of rain (Jun/Jul) or right after the monsoon (Sept-Dec). Please be advised if the flow is too high, the entry might be restricted. So it all depends on the rain and the water flow.
To reach the Agaya Gangai, one has to get down 1000+ steps (to be precise 1296 steps and a few rocks). Climbing down is much easier and probably takes 20-30 mins. Climbing up is quite strenuous owning to the steep incline and could take anywhere from 45–60 mins depending on one’s agility. There are a few shelters on the way to get a break.
The waterfall is enclosed within the dense forest which increases its charm and grandeur. The water in the falls is considered to contain medicinal properties due to all the herbs spread across the forest, thru which it traverses. Locals believe taking a bath here, cures many ailments. Agaya Ganga is probably one of the most beautiful and photogenic waterfalls in Tamilnadu. At a height of 300 feet, the waterfall is a feast for the eyes. It is also known as Peraruvi (Grand falls) or Pei aruvi (Devil falls) – by the people of Kolli hills because of its scary resemblance and heavy water flow.
