Konkan, also known as the Konkan Coast or Kokan, is a rugged section of the western coastline of India. It is a 720 km long coastline. It consists of the coastal districts of western Indian states of Maharashtra, Goa, and Karnataka. The ancient Saptakonkana is a slightly larger region described in the Sahyadrikhanda which refers to it as Parashuramakshetra (Sanskrit for "the area of Parashurama").
The precise definition of Konkan varies, it is roughly the land between the Western Ghats and the Arabian Sea, and between the Tapti River in the north and the Chandragiri river in the south. The financial capital of country and Maharashtra state capital Mumbai: Mumbai city, Mumbai suburban fall in Konkan. It includes the following districts of modern India: Thane,Mumbai (Mumbai city, Mumbai suburban), Raigad, Ratnagiri, Sindhudurg, North Goa, South Goa and Uttara Kannada
The Sahyadri Mountain range ("Western Ghats") forms the eastern boundary of the Konkan, and the Arabian Sea marks the western boundary. The southern boundary is the Gangavali River. The Mayura River forms the northern boundary.
The Gangavali flows in the district of ("Uttara Kannada") in present-day "Karnataka State"; the cis-Gangavali portion (seen from Mumbai) of this district is the southernmost part of the Konkan. The towns of Karwar, Ankola, Kumta, Honavar and Bhatkal fall within the Konkan. The exact identity of the Mayura River, the northern limits of the historic Konkan, is indeterminate.
