Guddattu Sri Vinayaka Temple is in Kundapur taluk, Udupi district, Karnataka, India. Shree Guddattu Vinayaka Temple is a rare specimen of its kind that is unique in several aspects. It is unique in that it is a natural temple. In fact, a captivating huge rock surrounded by verdant fields itself is the abode of Lord Vinayaka here. Nowhere else in the world you can find cross-legged and pot-bellied Ganapa with a twisted trunk seated in a pool of water. Only here one can see the original self –existent presiding deity of this temple submerged upto the neck in water. As nature here is at her vibrant best, Guddattu is a dream-come-true to nature lovers. Yet another feature of the idol here that it was neither sculpted nor installed, it is self - manifest (Swayambhu). Ayar Koda Seva (which means 'Sahasrakumbabhisheka') is a special and unique seva performed here. Ayar Koda Seva starts with draining the water from the cave and then abhisheka with water is done till the water overflows from the cave, that is up to neck level of the Lord Ganapathi. This seva requires about thousand pots of water and hence Pooja is called 'Ayar Koda Seva'. This is very popular seva and devotees will have to book their dates at least six months in advance. Ganahoma, Mudiakkikadabu, Kayi Moodaganapathi, Panchakajjaya etc are also performed here.
