Kallar is a scenic location situated on the way to Ponmudi from Thiruvananthapuram city. Kallar gets its name from the River Kallar, which flows through the region. It is a favourite among picnickers and attracts many with an interest in trekking, angling and bird watching. Kallu means 'stone' and Aru means 'river', hence the name Kallar. The river has many attractive, round-shaped boulders and brightly-coloured pebbles, especially in the upper reaches of its course.
