The Nilgiri (blue mountains), are a range of mountains forming a part of the Western Ghats situated in the western part of Tamil Nadu state at the junction of Karnataka and Kerala states in Southern India. There are at least 24 peaks above 2,000 metres (6,600 ft) which make the southwestern edge of the Deccan Plateau.Here Doddabetta is the highest peak (2,637 metres or 8,650 feet) in the The Nilgiris District of Tamil Nadu state.


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: 11°22′30″N 76°45′30″E / 11.37500°N 76.75833°E / 11.37500; 76.75833. It has an area of 2,479 square kilometres (957 sq mi).[2]

It is connected via Nilgiri Mountain Railway.[3]


The Nilgiri Biosphere Reserve, which includes the Nilgiri Hills, forms a part of the protected bio reserves in India and is a part of UNESCO World Network of Biosphere Reserves. The UNESCO World Heritage Committee has started evaluating the Western Ghats, Nilgiri Sub-Cluster (6,000+ km²) for selection as a World Heritage Site.[4] Such a site would include all of Mukurthi National Park in the south-eastern corner of the Nilgiris.[citation needed]

The high steppes of the Nilgiri Hills have been inhabited since prehistoric times as the large number of artefacts unearthed by excavators demonstrates. A particularly important collection from the region can be seen in the British Museum, including those assembled by colonial officers James Wilkinson Breeks, Major M J Walhouse and Sir Walter Elliot.[5] 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.[6]

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 criminals 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.[7]

With a detachment of Europeans and Indian sepoys, he set out on his mission on 2 January 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.[8] In the 19th century, when the British Straits Settlement shipped Chinese convicts to be jailed in India, the Chinese men then settled in the Nilgiri mountains near Naduvattam after their release and married Tamil Paraiyan women, having mixed Chinese-Tamil children with them. They were documented by Edgar Thurston.[9] Paraiyan is also anglicized as "pariah".

Snowdon, Club Hill and Elk Hill with Doddabetta, form the impressive Udhagamandalam Valley.

Devashola (height: 2,261 metres (7,418 ft)), notable for its blue gum trees, is in the south of Doddabetta range.

Kulakombai (1,707 metres (5,600 ft)) is east of the Devashola. The Bhavani Valley and the Lambton's peak range of Coimbatore district stretch from here.

Hullikal Durg: (height: 562 metres (1,844 ft)), 11°19′N 76°53′E / 11.317°N 76.883°E / 11.317; 76.883 (Hullikal Durg) In the Kannada language, Hulikal Durg means Tiger Rock Fort. The Sanskrit name of his place is Bakasura Parvata. It is 3 km. southeast of Coonoor. Tropical pine forest flourishes at the base of this hill, while the valleys support green foliage.

Coonoor Betta (2,101 metres (6,893 ft)) is also called Teneriffe. It is on the northern side of the gorge, accommodating the Nilgiri Mountain Railway to Coonoor.

Rallia Hill (height: 2,248 metres (7,375 ft))11°25′N 76°53′E / 11.417°N 76.883°E / 11.417; 76.883 (Rallia Hill) is in the midst of a reserved forest and almost equidistant from Udhagamandalam and Kotagiri.

This peak, dedicated to the deity Rangaswamy, is considered holy by the people of the surrounding villages.

Avalanche hill of this range has the twin-peaks of Kudikkadu (height: 2,590 metres (8,497 ft)) and Kolaribetta (2,630 metres (8,629 ft)).

Derbetta (or Bear Hill) (height: 2,531 metres (8,304 ft)) and Kolibetta (height: 2,494 metres (8,182 ft)), south of the Ouchterlony valley, are a continuation of the Kundah range.

Mukurthi Peak

Mukurthi Peak 2,554 metres (8,379 ft)) 11°23′29″N 76°31′38″E / 11.39139°N 76.52722°E / 11.39139; 76.52722 (Mukurthi Peak), Pichalbetta (height: 2,544 metres (8,346 ft)) and Nilgiri Peak (2,474 metres (8,117 ft)) 11°24′0″N 76°30′4″E / 11.40000°N 76.50111°E / 11.40000; 76.50111 (Nilgiri Peak) are the important heights of this area. These three hills of the Wayanad district are generally low in relation to other heights of the district but are distinguished in relation to the generally uniform level of this area.

Muttunadu Betta (height: 2,323 metres (7,621 ft)) 11°27′N 76°43′E / 11.450°N 76.717°E / 11.450; 76.717 (Muttunadu Betta) is about 5 km, north northwest of Udhagamandalam. Tamrabetta (Coppery Hill) (height: 2,120 metres (6,955 ft)) 11°22′N 76°48′E / 11.367°N 76.800°E / 11.367; 76.800 (Tamrabetta) is about 8 km southeast of Udhagamandalam. Vellangiri (Silvery Hill) (2,120 metres (6,955 ft)) is 16 km west-northwest of Udhagamandalam.[10]


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.[2]


Wattle plantations in Nilgiris

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.[11]

The Nilgiri tahr animal can be found in the hills.[12]

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.[13] In addition there is one large, and several smaller hydro-electric impoundments in the area.[14] Scotch broom has become an ecologically damaging invasive species.[15]

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.[16]
