If you have more time, you can explore more of Munnar's scenic spots, such as Eravikulam National Park, where the endangered Nilgiri tahr can be found, or the Kundala Lake, surrounded by lush tropical forests.
If you have less time, you can skip the Marayoor Sandalwood Forests and Valara Waterfalls, but it's recommended not to miss the Idukki Wildlife Sanctuary.
