Vinayaka Chavithi at Ainavilli Vinayaka Temple (Vighneshwara Swamy Temple) in East Godavari district is the biggest festival at this region. In 2018, Vinayaka Chavithi Navaratri celebrations will begin on September 13 and ends on September 23.
Located in the midst of lush-green fields, coconut gardens, and the river Godavari, the temple is a prominent pilgrimage centre. It is believed that the deity here fulfils the wishes of devotees quickly. Devotees take a vow to visit the temple again once their wishes are fulfilled.
According to history of the temple, Daksha Prajapathi performed puja of Lord Vinayaka at this place for successful completion of Daksha Yagna. According to a legend, Vyasa Maharshi installed a Ganapathi idol here before setting out on his tour of South India. The presiding deity here, Sri Siddhi Vinayaka Swamy, has been installed in a unique way.
