Makaravilakku is an annual festival held on January 14 in Kerala, India at the shrine of Sabarimala. The festival includes the Thiruvabharanam (sacred ornaments of Ayyappan) procession and a congregation at the hill shrine of Sabarimala. An estimated half a million devotees flow to Sabarimala every year to have a darshan (vision) of this ritual.
The name refers to the lighting of a bright "vilakku" (lamp) three times on the hill beside the sanctum sanctorum of Sabarimala, which were used to communicated the completion of deeparadhana in ponnampalamedu (and compare Makara Jyothi).
