It is a popular tourist destination and is referred to as the "Princess of Hill stations" with much of the local economy is based on the hospitality industry serving tourism. As per the 2011 census, the city had a population of 36,501.

## Etymology

The word Kodaikanal is an amalgamation of two Tamil language words: kodai meaning "gift" and kanal meaning "forest" translating to "gift of the forest".

## History

The earliest references to Kodaikanal and the Palani hills are found in Tamil Sangam literature. Tamil composition Kuṟuntokai, the second book of the anthology Ettuthokai, mentions the mountainous geographic region (thinai) of Kurinji. The region is associated with Hindu god Murugan and is described as a forest with lakes, waterfalls and trees like teak, bamboo and sandalwood. The name of the region, Kurinji, derives from the name of the famous flower Kurinji found only in the hills and the occupants of the region were tribal people whose prime occupations were hunting, honey harvesting and millet cultivation. The hills were populated by the Palaiyar tribal people.
In 1821, a British Lieutenant, B. S. Ward, climbed up from his headquarters in the Kunnavan village to Kodaikanal to survey the area and reported of beautiful hills with a healthy climate with about 4,000 people living in well-structured villages. In 1834, J.C Wroughten, then revenue collector of Madura and C. R. Cotton, a member of the Madras Presidency's board of revenue, climbed up the hills from Devadanapatti. In 1836, botanist Robert Wight visited Kodaikanal and recorded his observations in the 1837 Madras Journal of Literature and Science. In 1852, Major J. M. Partridge of the Bombay Army built a house and was the person to settle there. In 1853, only six to seven houses were there when then Governor of Madras Presidency Charles Trevelyan visited in 1860. In 1862, American missionary David Coit Scudder arrived. In 1863, acting on a suggestion of Vere Levinge, then collector of Madurai, an artificial lake was formed.
In 1867, Major J. M. Partridge imported Australian eucalyptus and wattle trees and in 1872, Lt. Coaker cut a path along the steep south east facing ridge which overlooks the plains below and prepared a descriptive map the region. In the later half of the 19th century, it became a regular summer retreat for American missionaries and other European diplomats as a refuge from the high temperatures and tropical diseases of the plains. In 1901, the first observations commenced at the Kodaikanal Observatory. In 1909, the area had developed into a small town with 151 houses and a functioning post office, churches, clubs, schools and shops. In 1914, the ghat road was completed. It continued to serve as a summer retreat during the British Raj and became a popular hill station later.

## Geography

The town sits on a plateau above the southern escarpment of the upper Palani Hills at 2,225 metres (7,300 ft), between the Parappar and Gundar valleys. These hills form the eastward spur of the Western Ghats on the western side of South India. It has an irregular basin as its heartland, the center of which is now Kodaikanal Lake. The lake is a man-made lake of circumference 5 kilometres (3.1 mi), formed by blocking three water streams in 1863.
North of the town, high hills slope down into the villages and on the east, the hill slopes less abruptly into the lower Palani. A precipitous escarpment facing the Cumbum valley is on the south with a plateau leading to Manjampatti Valley in the Anamalai Hills in the west. There are many streams and waterfalls.

### Flora and Fauna

In 1836, botanist Robert Wight visited Kodaikanal and recorded over 100 plant specimens. In 1861, Douglas Hamilton recorded 114 species of birds in Kodaikanal. In 1867, W T Blanford described a new species Callene albiventris of White-bellied blue robin, obtained by Samuel Fairbank from the Palani Hills. The native vegetation consisted of Meadows and grasslands on the hillsides with shola forests in the valleys. When the British established the town, big invasive species of pine, wattle and eucalyptus were planted and they became the dominant species replacing the native shola forests. There are numerous pear trees with flowering rhododendron and magnolia trees. Kurinji flower that blooms only once in 12 years is unique to the town.
Nilgiri Tahrs were reported in the open grasslands in the region in the 19th century. Other major fauna include Indian elephant, Indian gaur and Flying squirrel. There are many species of butterflies also found in the region. After multiple proposals over the years, the Kodaikanal Wildlife Sanctuary was notified by the Government of Tamil Nadu in 2013 and covers over 700 km$^2$ (270 sq mi). The lake has various introduced fishes.

### Climate

Kodaikanal has a monsoon-influenced subtropical highland climate (Cfb, according to the Köppen climate classification, with a Cwb tendency). The temperatures remain cool throughout the year due to the high elevation.

## Environmental pollution

Usage of plastic bags have been banned due to the pollution caused to the fragile ecosystem. In 1983, a second-hand mercury thermometer factory was shut down in New York and relocated to Kodaikanal. The factory owned by Unilever was shut down in 2001 over allegations of mercury contamination and serious environmental violations. When the factory was shut down, air and water-borne mercury emissions had already contaminated large areas of Kodaikanal and the surrounding forests with the same projected to remain for centuries. A Ministry of Labour committee in 2011 estimated that 11.2 tonnes of mercury could have been dispersed into the air and disposed of as waste from the thermometer factory. Unilever denied dumping the wastes and did not compensate the workers affected by the mercury poisoning and refused responsibility of cleaning up the contaminated soil. After years of legal cases in the Madras High Court, Unilever agreed to compensate the workers in 2016. Site remediation studies are being undertaken by national institutions based on which clean-up has to be done.

## In popular culture

Kodaikanal has been the location for many movie shootings.
