Himachal Pradesh is a part of the Indian Himalayas. It has wide valleys imposing snow mountains, limpid lakes, rivers and gushing streams. After India became free in 1947, a number of princely hilly states were integrated into a single unit to be administered by the Government of India. Himachal Pradesh came into being as a state of the India Union on April 15, 1948, by integrating 31 big and small hill states of the region. In 1956, it was converted into a Union Territory. Subsequently, some more hill areas of the Punjab state were added to this Union Territory and it was made into a full-fledged state, the status that it continues to have now. Himachal Pradesh today is one of the most important tourist destinations in India. The high hills of Himalayas welcome the trekkers from all over the world.
