Agastyakoodam, a cone shaped mountain with a height of 1868 m, is on the
Western Ghats. The main attraction of this spectacular peak is the
Neelakurinji, a flower which blooms only once in twelve years. Best time to enjoy this scenic beauty is from December to April. The peak can be approached on foot from
Bonakkad which is 61 km away from
Thiruvananthapuram. 32 km of trekking from
Neyyar Dam will bring one to Agastyakoodam. The peak was the home of sage
Agastya, a confirmed bachelor. Hence, the aborigines dislike the presence of women on the hill. So women are not allowed up the peak.
