The Nilgiri Mountains are a mountain range in India. They are found in the states of Tamil Nadu, Karnataka, and Kerala. These mountains connect two other important ranges: the Western Ghats and the Eastern Ghats.

The Nilgiri Mountains have many tall peaks. At least 24 of them are over 2,000 meters (6,560 feet) high. The very highest point is Doddabetta Peak, which stands at 2,637 meters (8,652 feet).

What's in a Name?

The name Nilgiri comes from two old Sanskrit words. Neelam means "blue" and giri means "mountain." So, Nilgiri means "Blue Mountains." People have used this name since at least the year 1117 CE.

It is believed that the name comes from the bluish flowers of the kurinji shrubs. These flowers cover the hills and make them look blue.

Where are the Nilgiri Mountains?

The Nilgiri Hills are located south of the Mysore Plateau. The Moyar River separates them from this plateau in the north.

Protected Areas

Several national parks are found around the Nilgiri Mountains. These parks help protect the animals and plants that live there.

  • Mudumalai National Park is in the northern part of the range. It covers an area of 321 square kilometers (124 sq mi). This park is where the states of Kerala, Karnataka, and Tamil Nadu meet.
  • Mukurthi National Park is in the southwest, in Kerala. It covers 78.5 square kilometers (30.3 sq mi). This park protects special grasslands and forests. It is home to the Nilgiri tahr, a type of mountain goat.
  • Silent Valley National Park is just south of these two parks. It covers 89.52 square kilometers (34.56 sq mi).

Protecting Nature

The Nilgiri Hills are part of the Nilgiri Biosphere Reserve. This reserve is a special protected area in India. It is also part of the UNESCO World Network of Biosphere Reserves. This means it is recognized internationally for its important natural environment.

A Look Back in Time

People have lived in the high areas of the Nilgiri Hills for a very long time. We know this because many old tools and items have been found there. Some of these ancient artifacts are now kept in the British Museum.

The name Nila was first used for this region in 1117 CE. A general from the Hoysala kingdom mentioned it in a report. He said he offered the peak of Nila Mountain to the goddess Lakshmi.

Early Explorers

In 1814, two explorers, Keys and McMahon, climbed the hills. They made maps and reported what they found. Later, two young British officers, Whish and Kindersley, explored the area more. They were impressed by the good climate and beautiful land.

British Influence

After the 1820s, the British developed the hills quickly. It became a popular place for them to visit in summer. In 1827, Ooty became the official summer capital of the Madras Presidency. Many winding roads were built through the hills. In 1899, the Nilgiri Mountain Railway was finished. This train line made it easier to travel to the mountains.

Habitats and Challenges

The main type of forest here is the tropical rainforest. You can also find montane forests, which are forests found in mountains. Sadly, many of these forests have been damaged. This is due to large tea plantations, easy access for vehicles, and planting of non-native trees like eucalyptus.

Threatened Plants

Some plants in the Nilgiris are in danger of disappearing.
