Kallar has a very unique specialty. It is famous for round-shaped boulders and pebbles and is situated en route to the popular hill station of Ponmudi. Starting right from the side of the Kallar Bridge, there is a track that will lead one to a medium sized, but captivating waterfall, popularly known as Meenmutti.
The lovely waterfall is situated about 3-4 kms from the main road. And further on, another couple of kms down the track through dense forests you will come face to face to Kombaikani waterfalls. These two magnificent waterfalls are situated on the upper reaches of the Neyyar Reservoir. The waterfalls and the dense and calm forests around them are worth a look. It is a popular site for picnickers and attracts many trekkers, hikers, bird lovers and wild life enthusiasts.
