If you really want to enjoy the local dishes (river fish), then it is worth visiting the Periyar hotel located near Varapuzha bridge. They have two outlets. One inside the Blue bazaar shopping village and another one immediately after that (Old one, facing pariyar river). While coming from Edappally or Ernakulam sie, it is on the right side, just before the Varapuzha bridge.
This 200+ years old Roman Syrian Catholic church is very close to Kadamakudy. Good place to visit for those who is interested in architecture and photography.

Cherai beach is very close to Kadamakudy, if you take the Chathanad route from Kadamakudy. Clicked this photograph with a compact lumix camera. The colours have come out well.
