Marayoor is the only place in Kerala that has a natural growth of sandalwood trees. The sandalwood factory of the Forest Department, the caves (muniyaras) with murals and relics from the New Stone Age civilization and the children's park spread across a hectare of land. Thoovanam Waterfall and Rajiv Gandhi National Park are also nearby. Marayoor occupies a vast area on the slopes of the Western Ghats in Idukki district and is an important pre-historic site in Kerala. Apart from the Dolmenoid cists (Dolmenoids were burial chambers made of four stones placed on edges and overed by a fifth one called the cap stone) in Muniyara, Marayoor is famous for its natural sandalwood forests and pre-historic rock paintings.
