Athirappilly Falls is a spectacular waterfall located in Thrissur's Athirappilly Panchayath in the Indian state of Kerala, particularly bordering the south-western coast of the country. Visitors will observe this natural beauty close to the Chalakudy River on Sholayar mountain ranges near the Vazhachal Forest Division. Measuring about 80 feet in height, the Athirappilly Falls is amongst the most popular tourist destinations of Kerala and it is also known as 'The Niagara of India', due to its impressive charm and grandness. The Chalakudy River is nearly 145 kms in length and its source is in the Anamudi Mountains based in the Western Ghats, flowing towards the direction of Arabian Sea through the Vazhachal Forest. As the Clalakudy River starts flowing near Athirappilly, it becomes rougher, separating into three different plumes and flowing down against large rocks and boulders.

Until the Chalakudy River reached Kannamkuzhi, it continues to remain turbulent for a distance of nearly one kilometre. Eventually the river flows calmly close to the dam at Thumburmuzhi. The beauty of this waterfall has inspired several movie directors to shoot numerable movies including 'Dil Se..' starring Shah Rukh Khan and Manisha Koirala, Tamil movie 'Iruvar' starring Aishwarya Rai and Mohanlal, 'Guru' starring Aishwarya Rai, 'Raavan', Tamil movie 'Punnagai Mannan' and others.

The area around Athirappilly Falls had been declared as an 'Important Bird Area' by the International Bird Association and according to the suggestions put forward by the Asian Nature Conservation Foundation, the region should be proclaimed as a national park or wildlife sanctuary.

Hydroelectric Power Project near Athirapilly
The creation of a 163 megawatt Athirappilly Hydro Electric Project had been planned by the Kerala State Electricity Board (KSEB) during 1994. It had been proposed that a dam measuring about 1, 020 feet in width and 75 feet in height would be built in Vazhachal Forest Division over the Chalakudy River. This decision was vehemently opposed by human rights groups and environmental bodies as it creation of the dam would take a toll on tourism, destroy the natural environment and threaten the ecosystem, apart from interfering with human rights. Critics also asserted that this would lead to drying up of the Athirappilly-Vazhachal waterfalls. Environmentalists also argued that the construction of a dam over the waterfall would dislodge the 'Kadars' who were the regional tribals of this area. However, the plan was approved by the Kerala Ministry of Environment and Forests, prodded by a report submitted by the Water and Power Consultancy Services (India) Ltd. or WAPCOS. The controversy regarding the hydroelectric project continued for several years.
