Sabarimala Sree Dharma Sastha Temple, dedicated to Lord Ayyappa, is the most famous and prominent among all the Sastha temples in Kerala. The temple is situated on a hilltop (about 3000 feet above sea level) named Sabarimala in Pathanamthitta district, which is unique. The temple is open to people belonging to all religions. There is a place near the temple; east of Sannidhanam (the abode of Lord Ayyappa), dedicated to Vavar (a close friend of Lord Ayyappa) which is called Vavaru Nada, an epitome of religious harmony. Another unique aspect of this temple is that it is not open throughout the year. It is open for worship only during the days of Mandalapooja, Makaravilakku, Vishu and also during the first day of every Malayalam month.
