On the slopes of nearby Elk Hill, the Rose Garden is home to over 2,000 varieties of roses. The Government Botanical Garden, created in the 19th century, features ferns, orchids and a prehistoric, fossilized tree.
The town was a popular summer retreat during British colonial rule, and the Stone House, in the east, is a Raj-era bungalow that now forms part of the Government Arts College. Close by is St. Stephen’s Church, known for its stained-glass windows. The single-track Nilgiri Mountain Railway, completed in 1908, travels over bridges and through tunnels to Mettupalayam, in the southeast. In the eastern outskirts of Ooty, towering Doddabetta Peak offers sweeping views of the town and the Nilgiri Hills. To the southwest, Avalanche Lake is framed by thick forests inhabited by birds.
