Tamil Nadu · Nilgiri Hills

Ooty (officially Udhagamandalam) was developed by the British in the early 1800s as a summer capital for the Madras Presidency. Its cool, temperate climate and tea-covered hills made it one of colonial India's most popular hill retreats, a reputation it's kept ever since.
The town's best-known landmark is the Nilgiri Mountain Railway, a UNESCO World Heritage steam "toy train" that has run since 1908, using a rack-and-pinion system on its steepest stretches between Ooty and the plains at Mettupalayam.
A boating lake in the town centre, built in the early 1800s by John Sullivan, the founder of Ooty.
The UNESCO-listed toy train connecting Ooty to the plains at Mettupalayam.
The highest point in the Nilgiris, over 2,600m, with a telescope house and valley views.
A terraced garden laid out in 1848, with an annual flower show each May.
A waterfall and boating spot about 20km from Ooty, set amid eucalyptus and pine forest.
