Arattupuzha Sastha Pooram / Temple / Map

The famous Ayyappa temple at Arattupuzha is just 14 kms south of Thrissur town. The temple here is a major attraction especially at the time of the annual Pooram festival that takes place in the months of April-May. The uniqueness of this festival is the ceremonial procession carrying images of deities of 41 neighboring temples to this village.
