Delhi Ridge
The Delhi Ridge, an extension of the Aravalli Hill Range in the National Capital Territory (NCT) of Delhi is a rocky hilly, forested area that lends a unique geographic character to Delhi. It is also called the green lungs of the city since it lowers the effects of pollution & provides a natural green belt to the city.
The Delhi Ridge is the tail end of the ancient Aravalli Hills, which are around 1,500 million years old & stretch around 800 km from the State of Gujarat, through Rajasthan & Haryana, and finally ends at Delhi. It is home to a wide variety of flora & fauna native to the Delhi region, preserving the ecological biodiversity of the NCR.
