My first visit to Irpu Falls was in October 2007, during a two-day bike ride in Coorg. I was there again this April. There were quite considerable changes between these two visits – prominent being the amount of water. My first visit was just after the monsoon & the latest being in the middle of summer.
One other major change was the man-made metal ramp below the falls. So that people can walk right under the falls & enjoy the water. That means more people visiting the place, more litter and complete loss of tranquility.

First visit to Irpu falls was on motorbike and second in a four wheeler. Hope to visit the place next time on my bicycle :)
PS: First photo was taken in Oct’07 and second in Apr’10
