Description
Nilgiri Hills, a mountainous region of Tamil Nadu state, southeastern India. The peaks of the Nilgiri rise abruptly from the surrounding plains to an elevation of about 6,000 to 8,000 feet (1,800 to 2,400 meters); one of them, Doda Betta (8,652 feet [2,637 meters]), is the highest point in Tamil Nadu. Part of the Western Ghats, the hills are separated from the Karnataka Plateau (north) by the Nayar River and from the Anaimalai and Palni hills (south) by the Palghat Gap. They are considerably cooler and wetter than the surrounding plains, the upper hills forming undulating grassy downs. Tea, cinchona (whose bark yields quinine), coffee, and vegetables are grown extensively.
