Paonta Sahib is one of the major industrial towns of Himachal Pradesh. It is located in the south of Sirmour district, on National Highway 7. Major industries are cement production (Cement Corporation of India in Rajban), power generation and renewable energy, pharmaceuticals (Sun Pharmaceutical, Mankind Pharma Limited), textiles, chemicals and food, as well as Asia's biggest limestone market at Sataun. Paonta Sahib is also an important place of worship for Sikhs, hosting a large Gurdwara named Gurudwara Paonta Sahib, on the banks of the river Yamuna. The river is the boundary between the states of Himachal Pradesh and Uttarakhand. The town was founded by Sikh Guru Guru Gobind Singh. The Gurudwara Paonta Sahib has linkages to the tenth Sikh Guru, Guru Gobind Singh and the Sikh leader Banda Singh Bahadur. Its original name was Paontika. "Paon" in Hindi means feet and "tika" in Hindi means became stable. It is believed that Guru Gobind Singh and his horse stopped at this place and he decided to stay here. He lived here for 4 and half year as he never stayed so long at any place in his entire life. He wrote many Sikh religious books here and then went to Anandpur Sahib to establish the Khalsa Panth. The Gurudwara also houses a museum which contains a lot of antiques and weapons used by Guru Gobind Singh during his stay. Paonta Sahib has a sub-tropical continental monsoon climate characterised by a seasonal rhythm, hot summers, slightly cold winters, unreliable rainfall and great variation in temperature (0 °C to 40 °C). In winters, frost sometimes occurs during December and January. It also receives occasional winter rains from the western disturbance.
