The Nag Nathaiya Festival is one of the most cherished cultural and religious celebrations in Varanasi, held annually at the historic Tulsi Ghat. Rooted in devotion and mythology, this festival dramatizes Lord Krishna’s legendary triumph over the serpent Kaliya. First organized in the 16th century by the revered poet-saint Tulsidas, it has continued for over four centuries as a vibrant part of the Krishna Leela tradition.
