Start with an easy 3km trek through the dense forest of Koli Hills to Agaya Gangai Waterfalls, one of the most beautiful waterfalls in the area. Afterward, head to Aridhole Murugan Temple, an ancient temple situated at the foothills of Koli Hills. Be in awe of the intricate carvings and structures of the temple before heading for lunch in one of the local restaurants that serve authentic Tamil Nadu meals.
Start the day by exploring the vibrant and colorful local market situated at the foothills of Koli Hills. Buy handmade items made by locals and relish the fruits being sold on the streets. Then, go for a relaxing boat ride in the Nayinar river while enjoying the serene surroundings of the Koli Hills range. Before ending the day, visit the Koliyur Falls, a scenic waterfall that requires a 2 km trek from the main road. The trek is worth it once you get to witness the grandeur of the falls surrounded by lush green forests.
If you have more time, Masinagudi Wildlife Sanctuary offers wildlife safaris to witness leopards and elephants. Also, you can visit the Aranmanaikar Dam for boating and get a panoramic view of the surrounding hills and villages. For a shorter trip, you can opt to only visit Agaya Gangai Falls and Koliyur Falls. It's better to avoid the monsoon season as the trails can be slippery and dangerous. Do carry water bottles, snacks, and a first-aid kit along with you during treks.
