Bhoothathankettu is a dam and tourist spot in Kerala, India. It is situated in the village of Pindimana, about 10 km away from the town of Kothamangalam and 50 km away from the main city of Kochi. At the time of Malayatoor pilgrim season, travellers use the roads through the forest.
Large blocks of unshaped stones are placed on both sides of the Periyar River to form the dam, making it look like a natural dam built by superhumans. The name Bhoothathan Kettu, means "monster dam"; past generations believed it was built by a Bhootham (monster).
