Sharp cliffs of hills and narrow valleys of the Aravallis dominate the landscape of Sariska, whose forests are dry and deciduous. Within the Sariska wildlife sanctuary there are the ruins of medieval temples of Garh-Rajor, belonging to the 10th and 11th centuries. A 17th century castle on a sharp hilltop at Kankwari, provides a panoramic view of flying Egyptian vultures and eagles. The area was declared a sanctuary in 1955 and became a National Park in 1979.
