Thirunelli is often referred to as the “Kashi of the South” due to its famous Thirunelli Temple. Dedicated to Lord Vishnu, this ancient temple is believed to be over 1,000 years old. Surrounded by dense forests and the Brahmagiri Hills, the temple exudes a sense of serenity that captivates every visitor. The sacred Papanasini stream, which flows near the temple, is said to wash away sins, attracting pilgrims from far and wide.
