The jackfruit grown on these mountains is known for its taste and fragrance and is often soaked in wild honey that is also harvested from these mountains. The mountains are covered by green vegetation in the spring and monsoon, and are streaked with streams. There are three reserved forests that are controlled by the Government of Tamil Nadu, namely Ariyur Solai, Kundur Nadu, Pulianjolai. It is not correct to regard the name kolli hills as being due to the incidence of deadly diseases such as malaria! It is because early literature records the existence of an image called kollippavai on top of these hills. This image was believed to represent the spirit of a maiden who lured wayfarers by her beauty and then killed them. The mountain is a site of pilgrimage, because of the Arapaleeswarar temple, which is believed to have a secret path to the Shiva temple in Rasipuram. This Shiva temple is said to have been built by Valvil Ori in the 1st or 2nd century when he ruled this area. "Arappaleeswara sathakam" is the poem which praises the Lord Arappaleeswarar. It is believed that this temple exists during the Sangam period itself.
