Start your nature-themed adventure at the Parambikulam Wildlife Sanctuary, located just over an hour away from Walparai. Home to a variety of wildlife, the sanctuary is known for its diverse flora and fauna and the teak plantation. Visitors can take a guided trekking tour along the trails to explore the sanctuary's natural beauty. You can also take a boat ride on the serene Parambikulam Reservoir and get a glimpse of the aquatic life, including the critically endangered, endemic fish - Black spotted turtle.
On day two, head to Aliyar Dam, a picturesque destination that boasts of serene surroundings and breathtaking scenery. The surrounding landscaped gardens also offer ample opportunity to relax and rejuvenate amidst nature. You can indulge in water sports activities such as boating and swimming or take a stroll around the beautiful landscape. Take the short hike to the scenic Monkey falls nearby to experience the wonderful nature and to have a refreshing dip in the cool waters of the fall.
If you have additional time, include a visit to the Anamalai Tiger Reserve or the Koolangal River. For a less nature-centric itinerary, check out the Kadamparai Dam or the Indira Gandhi Wildlife Sanctuary and National Park.
