The Nilgiri (Tamil: நீலகிரி, Badaga: நீலகி:ரி or blue mountains), often referred to as the Nilgiri Hills, are a range of mountains with at least 24 peaks above 2,000 metres (6,600 ft), in the westernmost part of Tamil Nadu state at the junction of Karnataka and Kerala states in Southern India. They are part of the larger Western Ghats mountain chain making up the southwestern edge of the Deccan Plateau.
The hills are separated from the Karnataka plateau to the north by the Moyar River and from the Anaimalai Hills and Palni Hills to the south by the Palghat Gap. The Nilgiris District of Tamil Nadu lies within these mountains. Its latitudinal and longitudinal dimensions are 130 km (Latitude: 11° 08' to 11° 37' N) by 185 km (Longitude: 76° 27' E to 77° 4' E). Central location is: . It has an area of 2,479 square kilometres (957 sq mi).
The Western Ghats, Nilgiri Sub-Cluster (6,000+ km²), including all of Mukurthi National Park in the south-eastern corner of the Nilgiris, is under consideration by the UNESCO World Heritage Committee for selection as a World Heritage Site.
The first recorded use of the word Nila applied to this region can be traced to 1117 AD in the report of a general of Vishnuvardhana, King of Hoysalas, who in reference to his enemies, claimed to have “frightened the Todas, driven the Kangas underground, slaughtered the Pallavas, put to death the Malayalas, terrified King Kala and then proceeded to offer the peak of Nila Mountain (presumably Dodabetta) to Lakshmi, Goddess of Wealth.
The original inhabitants of the Nilgiri Hills were the Toda, Badaga, Kota, Irula and kurumbas. The Nilgiri Hills were part of Chera Empire in ancient times. Later, the area came under the rule of the Western Ganga Dynasty, and then Hoysala empire in the 12th century. They then became part of the Kingdom of Mysore of Tipu Sultan who later surrendered them to the British in the 18th century.
The first Europeans to attempt the grueling climb to the Nilgiris included an enigmatic Jesuit priest, Father Fininicio, in 1603. They struggled up the mountains, avoiding elephants, tigers and other wild beasts, and met the Todas at the top.
From 1799 these mountains were seen daily by the British authorities from the plains of Coimbatore. Revenue was collected from them for the British East India Company by a native renter. Excepting Dr. Ford and Capt. Bevan, who traversed the hills in 1809 with a party of pioneers, and some deputy surveyors under Colonel Monson, who partially mapped the area, no British had ventured to explore the all but unknown region.
In 1814, Mr, Keys, a sub-assistant, and Mr. McMahon, an apprentice in the Survey Department, ascended the hills by the Danaynkeucottah Pass, penetrated into the remotest parts, made plans, and sent in reports of their discoveries. As a result of these accounts, Messrs. Whish and Kindersley, two young Madras civilians, ventured up in pursuit of some criminal's taking refuge in the mountains, and proceeded to reconnoitre the interior. They soon saw and felt enough favorable climate and terrain to excite their own curiosity and that of others.
In 1819, John Sullivan, the British Collector of Coimbatore, set out to explore the Nilgiris after obtaining an order from the British East India Company charging him to investigate the "origin of the fabulous tales that are circulated concerning the Blue Mountains to verify their authenticity and to send a report to the authorities".
With a detachment of Europeans and Indian sepoys, he set out on his mission on January 2, 1819. The journey involved crossing rough and harsh terrain, steep precipices and danger from wild animals. After an expedition that lasted for six days and loss of the lives of some of the expedition members, Sullivan finally reached a plateau from where he proudly hoisted the British flag.
In May, 1819, the same tourists from Coimbatore, accompanied by Monsieur Leschnault de la Tour, naturalist to the King of France, repeated their excursion. They asserted the temperature in the shade to be 74 °F (23 °C) at a time when the temperature of the plains was up to 100 °F (38 °C). Such a climate within the tropics was considered so great an anomaly that few at first believed its existence.
After the early 1820s, the hills were developed rapidly under the British Raj because most of the land was by then privately owned by British citizens. It was a popular summer and weekend getaway for the British during the colonial days. In 1827 Ooty became the official sanatorium and the summer capital of the Madras Presidency. Many winding hill roads were built. In 1899, The Nilgiri Mountain Railway was completed by influential and enterprising British citizens with venture capital from the Madras government.

The highest waterfall, Kolakambai Fall, north of Kolakambai hill, has an unbroken fall of 400 feet (120 m). Nearby is the 150 feet (46 m) Halashana falls Second is Catherine Falls, near Kotagiri, with a 250-foot (76 m) fall, named after the wife of M.D. Cockburn, believed to have introduced coffee plantations to the Nilgiri Hills. The Upper and Lower Pykara falls have falls of 180 feet (55 m), and 200 feet (61 m), respectively. The 170 feet (52 m) Kalhutti Fall is off the Segur Peak. The Karteri Fall, near Aruvankadu had the first power station which supplied the original Cordite Factory with electricity. Law's Fall, near Coonoor, is interesting due to its association with the engineer Major G. C. Law who supervised building of the Coonoor Ghat road.
Over 2700 species of flowering plants, 160 species of fern and fern allies, countless types of flowerless plants, mosses, fungi, algae, land lichens are found in the sholas of the Nilgiris. No other Hill station has so many exotic species.
Much of the Nilgiris natural Montane grasslands and shrublands interspersed with sholas has been much disturbed or destroyed by extensive tea plantations, easy motor vehicle access and extensive commercial planting and harvesting of non-native eucalyptus and wattle plantations (Acacia dealbata, Acacia mearnsii and cattle grazing. In addition there is one large, and several smaller hydro-electric impoundments in the area. Scotch broom has become an ecologically damaging invasive species.
Threatened plants of the Nilgiris include the Vulnerable species: Miliusa nilagirica, Nothapodytes nimmoniana, Commelina wightii and
Rare species: Ceropegia decaisneana Ceropegia pusilla, Senecio kundaicus and endangered species: Youngia nilgiriensis, Impatiens neo-barnesii, Impatiens nilagirica, Euonymus angulatus and Euonymus serratifolius.
