If you have extra time, you can visit the Punnathurkotta Elephant Sanctuary and Guruvayoor Temple. If you have a lesser amount of time, you can skip Athirappilly Waterfalls and visit the Sakthan Thampuran Palace instead. Don't forget to carry sunglasses, sunscreen, and a hat to protect yourself from the sun and mosquitoes. Finally, try to avoid visiting during festivals as the crowds can get overwhelming.
