Haryana was carved out of the Indian state of Punjab on 1st November 1966. The state has Uttar Pradesh on its eastern border, Punjab on its western border, Himachal Pradesh and Shivalik Hills on its northern border and Delhi, Rajasthan and Aravali Hills on its southern border. Haryana has a network of tourist complexes, named after birds. These have been set up along the national / state highways and at districts, towns and at places around Delhi. Some of the tourist complexes in Haryana are Badhkal Lake, Dabchik, Jungle Babbler, Karna Lake, Kala teetar, Surajkund and Yadvindra Gardens at Pinjore. The state of Haryana is bounded by Uttar Pradesh in the east, Punjab in the west, Himachal Pradesh in the north and Rajasthan in the south. The Union Territory of Delhi juts into Haryana and is encompassed by it on three sides. The south west of the Haryana is dry sandy and barren. The natural boundaries are: the Shivalik hills in the north, River Yamuna in the east and river Ghaggar in the west. The south western boundary is provided by the range of Aravalli hills, which run through southern Delhi and the Gurgaon district up to Alwar. There are some high ridges running from the north-west to south-east with numerous spurs branching out in all directions. These hills are known as the Morni and Tipra ranges. They belong to the outer ranges of the Himalayas.
