Agastyarkoodam Peak is a spectacular peak in the Western Ghats that rises to a majestic height of about 1868 m in the form of a sharp cone. It is accessible only on foot, with 61 kms of trekking from Bonacaud, and 32 kms from Neyyar Dam.
A haven of rare herbs and medicinal plants, its slopes offer a breathtaking sight when they transform into colorful glades of the 'Neelakurinji' a flower, which blooms only once in twelve years. Acording to a local belief, the peak was the abode of sage Agasthya, who was a confirmed bachelor. Hence, the aborigines dislike the presence of women on the hill. Women are not allowed up the peak.
