The annual feast at Parumala is the feast in honor of St. Gregorios, the only canonised saint of the Malankara Orthodox Church. The feast is celebrated at the St. Paul's and St Peter's Church at Parumala with much religious fervor.

The feast at Parumala is celebrated every November in the first week of the month.  The church town of Parumala turns into a throbbing town with thousands of devotees turning up to offer prayers at the saint's tomb. The festivities begin with the Catholicose of the East and the Malankara Metropolitian, leading the holy tri-mass at the Parumala Church that houses the saint's tomb. The mass is at times followed by theological discussions and seminars. The celebrations at the Parumala Church come to an end with a holy Raasa followed by the Kodiyirakku ceremony later in the afternoon.
