Sariska National Park lies in the Aravalli hills and is the former hunting preserve of the Maharaja of Alwar. The reserve was declared a wildlife sanctuary in 1958 and came under the "Project Tiger" as a tiger reserve in 1979. The park covers quite a large area of 800 square kilometers, 480 square kilometers of which form the core area of the national park.
Due to the presence of monuments of religious importance located within the park boundaries, the park authorities are compelled to keep the park open throughout the year. Unfortunately, the only restrictions they are able to impose during this "off-season" period are those on entry into the jungle routes. The main road is kept open all year round. The season during which the jungles can be properly explored is from November to June.
