The monsoon brings happiness. And waterfalls at Courtrallam. The water falls on rocks and tiny droplets are sprinkled into the air. Thus, giving a `fog-like` appearance. The breeze carries this `fog` far. The phenomenon is called `Saral` in Tamil. The falls are known for its medicinal value. This is the only `spa` of its kind in the South. Cultural programmes, competitions, fun and frolic make this festival remarkable.
