The Siliguri Corridor, often called the “Chicken’s Neck”, is one of the most strategic and sensitive regions of India. It connects the mainland of India to the North-Eastern states. Because of its geographical location and security importance, it is frequently asked in UPSC, State PCS, SSC, Defence Exams, and other government competitive exams.

What is the Siliguri Corridor?

The Siliguri Corridor is a narrow stretch of land located in West Bengal, near the city of Siliguri.

• Length: Around 60 km

• Width: Varies between 20–22 km at its narrowest part

• Connects: The rest of India with Assam, Arunachal Pradesh, Meghalaya, Mizoram, Manipur, Tripura, Nagaland, and Sikkim
