Start your day with a visit to the Agaya Gangai Waterfalls, a beautiful waterfall located in the midst of the hills. The falls are a 30-minute trek from the entrance, but the view is worth it. Spend the afternoon at the Masila Falls, which is less crowded and offers a peaceful atmosphere. In the evening, take a short drive to the Arappaleeswarar Temple, a historic temple dedicated to Lord Shiva. The temple is situated on a hill, and offers a stunning view of the valley below.
Start your day with a visit to the Kolli Hills Botanical Garden, which is home to a wide variety of flora and fauna. Spend the afternoon exploring the Siddhar Caves, a group of 12 ancient caves that have been used by sages and hermits for centuries. In the evening, head to the Botanical Garden viewpoint to watch the sunset over the hills.
If you're looking for more adventure, consider taking a hike to the Kollimalai Waterfalls or trekking to the top of the Agaya Gangai Waterfalls. You can also take a day trip to the nearby city of Salem, which is home to a number of historic temples and cultural attractions. To maximize your fun, be sure to bring comfortable shoes, a water bottle, and a camera to capture all the beautiful sights.
