Overview
The Nilgiris district is an administrative district of the state of Tamil Nadu in southern India. Located in the Nilgiri Hills, a part of the Western Ghats, it is one of the smallest districts in Tamil Nadu by area and one of the most sparsely populated. The district headquarters is at Udhagamandalam (Ooty), a hill station that developed during the British colonial period as a summer retreat. The name "Nilgiris" derives from the Tamil and Sanskrit roots meaning "Blue Mountains".

Geography
The district occupies a plateau region of the Nilgiri Hills, with elevations rising to over 2,600 metres at Doddabetta, the highest peak in Tamil Nadu. The terrain consists of rolling grasslands (locally known as downs), shola forests in valley folds, and large expanses cultivated with tea. The district shares borders with Karnataka to the north and Kerala to the west, and with the Tamil Nadu districts of Erode and Coimbatore to the east and south. Major rivers and streams include the Bhavani, Moyar and Pykara, several of which have been dammed for hydroelectric power.
The district forms a key part of the Nilgiri Biosphere Reserve, which is the first biosphere reserve declared in India. Mudumalai National Park and Tiger Reserve, located in the district, adjoins Bandipur (Karnataka) and Wayanad (Kerala) protected areas, forming a contiguous wildlife landscape.
Administration
The district is divided into administrative taluks including Udhagamandalam, Coonoor, Kotagiri, Gudalur, Pandalur and Kundah. Major towns are Udhagamandalam, Coonoor, Kotagiri and Gudalur. The district is represented in the Lok Sabha by the Nilgiris parliamentary constituency, which is reserved for Scheduled Castes.
History
The Nilgiri Hills have been home to indigenous communities such as the Toda, Kota, Badaga, Irula and Kurumba for centuries. European exploration began in the early 19th century; John Sullivan, then Collector of Coimbatore, is generally credited with opening up the hills for British settlement in the 1820s and establishing Ootacamund as a colonial hill station. The hills subsequently became the summer headquarters of the Madras Presidency.
The Nilgiris was carved out as a separate district during the British administration. Tea and cinchona plantations were introduced in the 19th century and transformed the local economy and landscape. The Nilgiri Mountain Railway, a metre-gauge rack railway connecting Mettupalayam with Udhagamandalam via Coonoor, was opened in stages from 1899 and was inscribed as a UNESCO World Heritage Site in 2005 as part of the Mountain Railways of India.
Economy
The district's economy is dominated by plantation agriculture, particularly tea, which is cultivated by both large estates and a substantial body of small growers. Other significant crops include coffee, spices, vegetables grown in the cooler climate (potatoes, carrots, cabbages), and flowers such as roses and chrysanthemums. Tourism is a major source of employment, drawing visitors to Ooty, Coonoor and Kotagiri, and to natural attractions including Mudumalai, Pykara and Avalanche. Hydroelectric generation in the Kundah and Pykara schemes contributes to the state grid.
Demographics and culture
The population is largely Tamil-speaking, with significant communities of Badagas, who form a major group in the hills, and smaller populations of Todas, Kotas, Irulas and Kurumbas, recognised as Scheduled Tribes. The district also has Malayali and Kannadiga populations, especially in Gudalur and along the western fringes. The Toda community is distinctive for its pastoral, buffalo-centric culture and traditional barrel-vaulted huts. Christianity has a long-standing presence due to 19th-century missionary activity, and churches such as St Stephen's in Ooty date from the colonial period.
Environment and conservation
The Nilgiris are recognised globally for biodiversity, with endemic species including the Nilgiri tahr, Nilgiri langur and Nilgiri flycatcher. Concerns include the spread of invasive species such as wattle and eucalyptus into native shola–grassland mosaics, landslides during the southwest monsoon, and pressures from tourism and unregulated construction. Conservation programmes, both governmental and through NGOs based in Kotagiri and elsewhere, focus on shola restoration, indigenous livelihoods and wildlife corridors.
Transport
The district is connected by State Highways to Coimbatore, Mysuru and Kozhikode. The ghat road from Mettupalayam to Coonoor and Ooty (NH 181) is the principal access route. The Nilgiri Mountain Railway provides a heritage rail link from Mettupalayam, where it connects with the broad-gauge network. The nearest major airport is at Coimbatore.
