Neyyar Dam located about 32 km from Thiruvananthapuram is a repository for some of the rarest medicinal herbs and it is a popular picnic spot. The lake formed by the dam across the Neyyar River is the bluest of the blue, making boating irresistible for tourists.
The Neyyar Wildlife Sanctuary of which the dam is a part is the habitat of over a hundred species of fauna including the Asian Elephant, Tiger, Leopard, Slender Loris and reptiles like King Cobra, Travancore Tortoise, etc. A crocodile breeding center and a lion safari park are also located at the dam site.
