Ooty which is also known as Udhagamandalam, is a town, a municipality, and the district capital of the Nilgiris district in the Indian state of Tamil Nadu. It is located 80 km north of Coimbatore. It is a popular hill station located in the Nilgiri Hills. Ooty is situated deep within the Nilagiri hills (which can be literally translated as The Blue Mountains). It is unknown whether this name arises from the blue smoky haze given off by the eucalyptus trees that cover the area or from the kurunji flower, which blooms every twelve years giving the slopes a bluish tinge.
