Bhoothathankettu Dam located near kothamangalam in Eranakulam district of Kerala is a popular tourist spot.This barrage built across Periyar river is part of P.V.I.P (Periyar valley Irrigation Project) which diverts water from Periyar river through a large network of canals for irrigation purpose.Large reservoir created by pristine Periyar river with virgin evergreen forests and mountains in the background makes this place spectacular. Bhoothathankettu is located at a distance of 10 kms from Kothamangalam, which is the nearest town and 55 kms from kochi.
The word Bhoothathankettu literally means “ghost dam” in malayalam language and is connected to Hindu mythology.The story states that long ago demons or “bhoothathans” set out to block the Periyar river to submerge Thrikkariyoor temple.Lord Shiva, the presiding diety of the temple came up with an idea to deter them. He made the sound of a crowing rooster to make it appear that dawn has arrived. Demons left their work unfinished and ran off fearing daylight. As a proof to this mythological story today we can see huge stones blocking the Periyar river at old Bhoothathankettu area,making the river flow through a narrow space which demons did not manage to dam up.
Boating on beautiful and pristine Periyar river is a major tourist attraction at Bhoothathankettu.Boats are operated in the reservoir created by Bhoothathankettu Barrage on Periyar river.Evergreen forests on both sides with western Ghat mountain ranges in the backdrop makes this river ride an unforgettable experience
Formation of this stone structure at old Bhoothathankettu remains a topic of conjecture.It is widely accepted that two major floods and landslides caused the enormous rocks to slide down the surrounding mountains and settle near old Bhoothathankettu.
Reservoir and surrounding forest is rich in flora and fauna and aquatic life.Bhoothathankettu ,which is only a few kilometers away from Thattekad Bird Sanctuary is a birding hotspot.Boat ride up the river,pedal boating and walk to old Bhoothathankettu are the major attractions.
