The valley between Thekkadi hills, Varshanadu hills and Kodaikanal hills is known as Kambam valley. This valley is considered as the green valley of Tamil Nadu.

The Western hilly region is much more complex than the Eastern Ghats.

Though the Western Ghats is a continuous range, it has a gap of 25 km at Palghat. To the south of Palghat gap, hills such as Andipatti, Elamalai and Agathiya malai are found.

The average height of the Western hilly region is from 1000 m to 1500 m.

From the Nilgiris of Tamil Nadu and Anaimalai hills of Kerala, an offshoot runs at a height of 1500 m to 2000 m in the east. These are called Palani hills.

To the south of Palani hills, there are two other ranges namely, Varshanadu and Andipatti hills running parallel to the Cardamom hills.

Pamban Island, also known as Rameswaram Island, is located between the Indian mainland and Sri Lanka.

• The gap in between Varshanadu hills and Agathiya malai is called the Shenkottai pass.

The Palakkad gap and Shenkottai gap are the only breaks in the long chain of hills that border Tamil Nadu on the west.

• Doddabetta is the highest mountain in the Nilgiri hills at 2,637 metres (8,650 feet).
