The eastern and western tips of the Tamilnadu are defined by the Point Calimere and Mudumalai wildlife sanctuaries while the northern extreme is Pulicat lake and the southernmost tip is Kanyakumari, the land's end. Tamil Nadu is principally washed by the Cauvery, originating in Coorg in neighbouring Karnataka. Chennai, the capital of Tamil Nadu is known for its beautiful beach resorts.
Udhagamandalam (Ooty), the capital of Nilgiri district, is popularly known as the "Queen of hill stations' among the tourist circuits. It is situated at a distance of 105 km away from Coimbatore.
