Parunthumpara is a village in Kuttikanam, Kerala's Idukki District. it is one of the famous places to visit in Kuttikanam, the meaning of 'Parunthumpara' is Parunthu = Eagle & Para = Rock, The main attractions of Parunthumpara are Suicide Point and Tagor Head (a rock that appears to have the shape of Tagor, an Indian poet's, head). A nearby tourist spot is Thekkady.
I wont't recommend travelling by bus, as it takes lot of time, and also you can't visit other famous places which are near to Parunthupara, like, Panchalimedu, valanjamkanam water falls, & pine forest, you can cover these spots in a single day by a private vehicle.
