Edakkal Caves are a prehistoric site where cave paintings and petroglyphs have been discovered, dating back to around 6,000 BCE. The trek to the caves is a bit challenging, but the view from the top is worth it. Be sure to carry plenty of water and wear comfortable shoes.
Soochipara Waterfalls is a three-tiered waterfall cascading from a height of 200 meters. You can enjoy a refreshing swim in the pool at the base of the falls. The surrounding rainforest adds to the charm of the place. Be aware that the path to the falls can be slippery and steep.
Banasura Sagar Dam is the largest earthen dam in India and the second-largest in Asia. The dam is set in a picturesque location surrounded by hills and forests. You can go boating or trekking in the nearby hills. There is also a park with a children's play area and an aquarium on site.
Pookode Lake is a natural freshwater lake surrounded by forests and hills. You can go boating, fishing, or take a leisurely stroll on the walking path around the lake. There is also a small aquarium and a children's park on site.
If you have more time, you can also visit the Wayanad Wildlife Sanctuary, Thirunelli Temple, or the Chembra Peak. To maximize your fun, try to visit the attractions early in the morning to avoid the crowds. It is also a good idea to carry snacks, sunscreen, and insect repellent with you. Finally, I suggest you hire a local guide for a more immersive experience.
