Bhoothathankettu is a dam and tourist spot in Kerala, India. It is situated outside the village of Pindimana, about 10 km away from the town of Kothamangalam and 50 km away from the main city of Kochi.
The original natural dam has been supplemented by a modern dam in 1982, impounding the Bhoothathankettu Reservoir.
According to legends, some monsters planned to submerge the Trikkariyoor temple and presiding deity Lord Shiva by making a dam in the Periyar river and flooding the area. But Lord Shiva, suspecting trickery, came up with a plan to deter them. He made it appear that dawn was approaching by crowing like a rooster. The demons fearing the arrival of light fled from their task. But the remains is visible proof of their effort – the huge stones the demons were supposed to have rolled onto the river bed – the Old Bhoothathankettu, are still there. The Periyar flows through the narrow space which the demons did not quite manage to block.
Leisure activities like pedal boating and horse riding are also possible at the dam site. The Old Bhoothathankettu – the dam created by monsters – is a 1km trek from the dam site. The thick forest and ample water spaces provide perfect vantage for bird watchers and photographers.
