Nestled in the Aravali Hills over an area of about 800 sq. Km covering the grasslands, dry deciduous forests, cliffs and rocky landscape, lays the Sariska National Park, now known as The Sariska Tiger Reserve. This area was once hunting preservation of The Maharaja of Alwar. The Reserve is known for its majestic Royal Bengal Tigers. It was declared as a national park in 1982.

The protected area is a part of the Aravali Range and the Kathiawar-Gir dry deciduous forests ecoregion. In 1978, it was given the status of Tiger Reserve under the Project Tiger. It is the first tiger reserve to relocate the Tigers (from Ranthambore) successfully. As it lies in the lap of Aravali Hills, it holds an abundant amount of mineral resources like copper.
