If you have more time, you can also visit the Kallar River, Meenmutty Waterfalls, and Thiruvananthapuram Zoo. For adventure seekers, you can go paragliding or zip-lining in the hills. If you have less time, you can skip Peppara Wildlife Sanctuary, but it's highly recommended. Make sure to pack warm clothes as it can get chilly at night in Ponmudi.
