Agasthyakoodam (also known as Agasthymala) is one of the highest peaks in the Western Ghats. 1868m above sea level, this mountain is located in Ponmudi, the nearest hill station to Thiruvananthapuram. Agasthyakoodam is a pilgrimage centre for devotees of Sage Agasthya, one of the 7 rishis of the Hindu Puranas. A full-sized statue of Agasthya lies atop the peak where devotees can place offerings and perform rituals. Due to its sheer height, Agasthyakoodam can only be accessed by trekking. While the Kerala government favours pilgrimages to the peak, the Tamil Nadu government only allows a certain number of pilgrims at a given time.
Agasthyakoodam is well known for its rich vegetation. Apart from the picturesque wilderness of its flora and fauna, approximately 2000 rare medicinal herbs and plants can be found here. Tourists are granted access to the area of the Biosphere Reserve only with permission from the Forest Department. Agasthyakoodam is not just a renowned religious destination, but also serves as the origin of many major rivers of Kerala and Tamil Nadu like the Thamarabarani, Karamana and Neyyar rivers.
