Originally re-named Udagamandalam from Ootacamund, this Tamil Nadu city is now more popularly known by its nickname, “Ooty.” Situated in Nilgiris district, it is undoubtedly one of the most well-known hill stations in South India. What is more interesting than its naming history is how this hill station was founded as a summer retreat during the British Raj period. This makes it a perfect spot for vacation, especially with family and kids.
