A unique feature of this temple is that the
shrikovil of Devi Parvati's idol is opened only for 12 days in a year, from the Thiruvathira asterism in the month of
Dhanu. During this occasion, huge crowds flock from across the states to the shrine. There is a temple well and to the south of it, one can see a cave, where Lord Shiva is believed to have appeared.
The festival time occurs on the Thiruvathira asterism of the Malayalam month of Kumbha (FebruaryMarch). The eight-day festival also includes Arattu. Another eight-day festival is celebrated during Ashtamirohini. Other festivals celebrated are Pradishta Divasom (day of deity installation), Mandala festival,
Vishu, Naga Pradishta and Navaratri.
