The centre point of attraction is the Pulikkottu Ayyappan Kavu where during Mandala Masam many devotees from in and around Kollengode came for wearing the sacred 'Rudraksha/ Tulasi Maala' for Sabrarimala Darshan. The major yearly festival of Ayyappan Kavu is 'Aarattu' (usually falls in the month of January) which was taken care for a long time by Vengunadu Kovilakom but is now conducted by Kollengode Mechants Welfare Association. 'Aarattu' in other words can be described as the festival marking the end of all the other Desa Vilakkus in Kollengode Desam. The prominent vilakkus celebrated in Kollengode prior to Arattu festival are; Oottara Ayyappan Vilakku, Iranji Mandam Desa Vilakku, Pulimannam Desa Vilakku, Puzhakkalthara Desa Vilakku, Minor Vilakku, Electricity Board Vilakku etc. A travel to Kollengode preferably in the last week of December is a nice time to enjoy all of these Vilakkus as each one of them falls either immediately after one or within a gap of max. one day with vibrant functions like Panchavadhyam, Seeveli, Elephant procession through the busy thoroughfare from the respective Desam to Ayyappan Kavu and back.
