Since antiquity, much of the Canara coast (now spelled as 'Kanara') occupied a culturally distinct area known as Tulu Nadu. Historically, Tulu Nadu lay between the Gangavalli River in the north and the Chandragiri River in the south. Currently, Tulu Nadu consists of the Udupi and Dakshina Kannada districts of Karnataka, and the Kasaragod taluka of Kerala. The Uttara Kannada district in general is considered to be the southernmost part of the Konkan coast. Specifically, the littoral region north of the Gangavalli River is traditionally included in the Konkan.
