It is a pilgrimage centre in Kerala in the western ghat mountain ranges of India and this temple is dedicated to Lord Ayyappa. The temple is situated amidst the 18 hills. The temple is situated on the hilltop at an elevation of 1260 mts, above sea level. The temple is surrounded by mountains and dense forests. Sabarimala is believed to be the place where Ayyappan meditated soon after killing the powerful demon, Mahishi.

The pilgrimage to Sabarimala is a singular example of one where pilgrims, without consideration of caste, creed, position or social status, go with one mind and one `mantra'.Vehicles can go up to Pampa – the holy river. Thereafter, pilgrims have to follow a path approximately four kms up a steep hill. There is a place near the temple (east of Sannidhanam), dedicated to the Vavar, a Musilim who was the associate of Ayyappan, called "Vavarunada".

The temple is open for worship only during the days of Mandalapooja( November 15 to December 26) Makaravilakku (January 15) and Vishu (April 14), and the beginning of every month in the Malayalam Calender. However, women - unless they are younger than six or older than sixty - are not allowed to come to Sabarimala. It is said that during the pilgrimage periods no tigers are found along the forest trails leading to Sabarimala. Sabarimala is the most famous piligrimage centre in Kerala.
