Athirappally - Vazhachal are the most famous waterfalls in Kerala. Located east of Chalakudy in Thrissur district near the entrance to the Sholayar forest ranges (Kerala's famed rain forests), Athirappally is 63 km, and Vazhachal, 68 km away from Thrissur. The falls are a part of the Chalakudy river stream which flows through the Vazhachal Forest Division. Athirappally, falls from a fairly good height of approximately 80 mts (150 feet) and joins the Chalakudy River below. The water fall can be viewed from several points. The view around and below from the flat rocky surface above the waterfall is breathtaking. The best period to view and enjoy the falls is during the monsoon (June - September). Though beautiful the river is also very dangerous especially during monsoon due to the slippery condition of the rocks, and the rocky bed has deep trenches hidden in between.
