Coonoor falls on the hilly way between Ooty and Mettupalayam, connected by the Nilgiri Mountain Railway. The most wonderful part of a visit to Coonoor from Ooty or Mettupalayam is journey by the Nilgiri Mountain Railway, the only toy train in South India and one of the world heritage sites in India. Coonoor is close to Ooty near the top and far from Mettupalayam at the foot of the Nilgiri Hills.
