If you have more time, don't miss out on visiting the Agasthya Mala Peak, where you'll get an opportunity to experience the rich biodiversity of the Western Ghats; the Kanakakunnu Palace, which is a great example of traditional Indian architecture; or the Sri Chitra Art Gallery, where you can explore the artworks of Indian artists.
If you have less time, you can prioritize your visit by choosing the locations that interest you the most and skip the others.
