The Nilgiri hills have been the home of the Toda tribe for centuries. Coonoor began to develop as a tourist destination in the 19th century when the British made the region a popular hill station. During summers Coonoor enjoys a mild climate while the burning sun scorches the surrounding plains. The British gentleman, who discovered these hills in 1819, returned the following year to build the first bungalow. Attracted by the temperate climate, the British elite lost no time and established their settlements in the hills. With them came tea plantations. The construction of a railway line accelerated the development of this region.
In those days the rail track from Chennai ended at Mettupalayam. From there the journey to the hills had to be undertaken on pony or bullock cart. In August 1891, the Governor of Chennai laid the foundation of the Nilgiri railway. The concourse was ready within three years, after which a new company undertook the project. In 1897, the line reached Coonoor and was officially inaugurated the following year. By 1908, the line was extended up to Ooty. Today the train is a major attraction and Coonoor attracts a large number of tourists round the year.
