The Sabarimala Sree Ayyappan Temple (ʃabəɾimala; ശബരിമല ശ്രീ ധർമ്മശാസ്താ ക്ഷേത്രം) is a Hindu temple complex located on the Sabarimala hill inside the Periyar Tiger Reserve, Ranni-Perunad Village, Ranni Taluk, Pathanamthitta district, Kerala, India. Nearest railway station is Chengannur railway station It is one of the largest annual pilgrimage sites in the world, with an estimate of over 10 to 15 million devotees visiting every year. The temple is dedicated to a Hindu Brahmachari (celibate) deity named Ayyappan also known as Dharma Shasta, who, according to one belief, is the son of Shiva and Vishnu. Sabarimala Temple exemplifies the convergence of diverse religions in India.
The temple is situated on a hilltop amidst eighteen hills at an altitude of 1,260 m (4,134) ft) above the mean sea level and is surrounded by mountains and dense forests. The dense forest, part of the Periyar Tiger Reserve, around the temple is known as Poongavanam. Temples exist in each of the hills surrounding Sabarimala. While functional and intact temples exist at many places in the surrounding areas like Nilakkal, Kalaketty, and Karimala, remnants of old temples survive to this day on the remaining hills.
In 1991, a PIL was filed, and the Kerala High Court told the Devaswom Board to keep the temple's customary practices. They also concluded that there is no difference between one group or class of Hindus, and when it comes to entering a temple, the ban only applies to women of a certain age and not to women in general.
On September 28, 2018, the Supreme Court of India, which had a panel of 4 male judges and 1 female judge, ruled by a majority of 4-1 to overturn the ban on women entering the temple. The state of Kerala expressed dissent towards the decision made by the Supreme Court.
The temple is open for worship only during the days of Mandala pooja (approximately 15 November to 26 December), Makaravilakku or "Makara Sankranti" (14 January), and Maha Thirumal Sankranti (14 April), and the first five days of each Malayalam month.
