Anchuruli Tunnel is a popular scenic attraction located near Kattappana in Idukki district, Kerala. It is part of the Idukki hydroelectric project and plays an important role in diverting water from the Erattayar dam into the Idukki reservoir.

The tunnel opens into a striking circular outlet where water gushes out, especially during the monsoon season, creating a dramatic and powerful visual. Surrounded by rocky terrain and lush greenery, the site has become a favorite spot for visitors and photography enthusiasts.

Though it is not a conventional tourist facility, Anchuruli Tunnel attracts many people for its natural beauty and engineering significance. Visitors are advised to maintain safety, as water flow can be strong and the rocks around the area can be slippery.
