Rajasthan is the largest state in the Republic of India. Most of the Great Indian Desert is located inside Rajasthan, as are some of the oldest mountain ranges in the world, the Aravallis. Mount Abu, sacred to the Jain religion, is also in Rajasthan. Rajasthan is the home of Keoladeo National Park, a World Heritage Site, and two tiger reserves, the Sariska Tiger Reserve and Ranthambore National Park. Rajasthan has very diverse flora and fauna, but several of the area’s animals and plants are endangered.
