About Kolli Hills
Nestled in the Namakkal district of Tamil Nadu, Kolli Hills, locally known as Kollimalai, is one of the most beautiful hill destinations in South India.

Part of the Eastern Ghats, Kolli Hills stands at an elevation of approximately 1,300 metres (4,265 feet) above sea level and spreads across nearly 280 square kilometres. Unlike many commercial hill stations, Kolli Hills retains its peaceful charm and offers visitors an authentic experience of Tamil Nadu’s natural beauty and tribal culture.
Mythology and Folklore
Kolli Hills has a rich cultural and mythological heritage that dates back thousands of years. According to local legends, the hills were protected by Kolli Pavai, a divine maiden believed to possess mystical powers. She is said to have guarded the region from evil spirits and invading forces, making her an important figure in local folklore. References to Kolli Hills can also be found in ancient Tamil Sangam literature, highlighting its historical and spiritual significance.

While the trek is moderately challenging, the scenic surroundings and refreshing atmosphere make it one of the most rewarding experiences in Kolli Hills.
