Himachal Pradesh is a state in India. It is located in the northwestern part of the country, and is bordered by the states of Jammu and Kashmir to the north, Punjab to the west, Haryana and Uttarakhand to the south, and Uttar Pradesh to the southeast. To the east, Himachal Pradesh shares an international border with China (Tibet).
The state has a population of over 7 million people, and its capital is Shimla. Himachal Pradesh is a popular tourist destination, and is known for its mountains, forests, and temples.
