Jammu and Kashmir is the northernmost state of India.Jammu and Kashmir is home to several valleys such as the Kashmir Valley, Tawi Valley, Chenab Valley, Poonch Valley, Sind Valley and Lidder Valley. The main Kashmir valley is 100 km (62 mi) wide and 15,520.3 km2 (5,992.4 sq mi) in area. The Himalayas divide the Kashmir valley from Ladakh while the Pir Panjal range, which encloses the valley from the west and the south, separates it from the Great Plains of northern India. Along the northeastern flank of the Valley runs the main range of the Himalayas. This densely settled and beautiful valley has an average height of 1,850 metres (6,070 ft) above sea-level but the surrounding Pir Panjal range has an average elevation of 5,000 metres (16,000 ft).Tourism in the Kashmir valley has rebounded in recent years, and in 2009, the state became one of the top tourist destinations of India.Gulmarg, one of the most popular ski resort destinations in India, is also home to the world's highest green golf course. However, the decrease in violence in the state has boosted the state's economy and tourism. It was reported that more than a million tourists visited Kashmir in 2011.
