Hiriadka (Periyadka in Tulu) is a town in the Udupi District in the Indian state of Karnataka. It is quite close to Udupi.[1] It is 15 km from Udupi and 24 km from Karkala. It lies on the Udupi-Hebri road and is famous for the fair along with a festival called Siri Utsava/Siri Jaatre which happens every year in the month of April–May.[2] Visitors from Udupi, Mangalore, Agumbe, Shimoga, and Dakshina Kannada districts are attracted to this popular fair. The Swarna River flows about 1 km from Hiriadka. After the renovation of the Sri Veerabhadra temple, Hiriadka has gained more popularity because of its attractive craftworks.[3] [4]
