Kalliyanathandu/Kalvarimount is placed 10 km from Idukki with panoramic view of peaks and forests. This famous Christian pilgrimage site perched atop a hill offers an aerial view of the Idukki Reservoir and its surroundings. It is also an ideal place for mountain climbers and trekkers. During Lent, the area turns into a pilgrimage centre as Christians go in a procession up the hillock.
