Kerala has unique geographical features that give the state a special tourist destination in the world tourism map. It is lies along the coastline, to the extreme southwest of the Indian peninsula. It is flanked by the Arabian Sea on the west and the mountains of the Western Ghats on the east. This land of Parasurama stretches north-south along a coastline of 580 km with a varying width of 35 to 120 km.
