Kanyakumari is located at 8.08°N 77.57°E. It has an average elevation of 300 metre. Contrary to the popular (and sensational) belief that Kanyakumari lies at the meeting point of three bodies of water, it borders only one: the Laccadive Sea to the southwest, south, and to the southeast. It is the confluence of the Western Coastal Plains and Eastern Coastal Plains.
It is located at the southern tip and southernmost point of the Indian Subcontinent. However, the southernmost point of the Republic of India is at Indira Point on Great Nicobar Island, at 6°45’10″N and 93°49’36″E.
Kanyakumari is used geographically to define southern end of the Coromandel Coast region.
Theories have been proposed that a continent named Kumari Kandam once existed to the south of Kanyakumari and the Indian Subcontinent of Asia. It is similar to the proposed continent of Lemuria, variously located in the Indian and Pacific Oceans.
