Both nature and culture are major components of Indonesian tourism. The natural heritage can boast a unique combination of a tropical climate, a vast archipelago of 17,508 islands, 6,000 of them being inhabited, the second longest shoreline in the world (54,716 km) after Canada. It is the world's largest and most populous country situated only on islands. The beaches in Bali, diving sites in Bunaken, Mount Bromo in East Java, Lake Toba and various national parks in Sumatra are just a few examples of popular scenic destinations. These natural attractions are complemented by a rich cultural heritage that reflects Indonesia's dynamic history and ethnic diversity. One fact that exemplifies this richness is that 719 living languages are used across the archipelago. The ancient Prambanan and Borobudur temples, Toraja, Yogyakarta, Minangkabau, and of course Bali, with its many Hindu festivities, are some of the popular destinations for cultural tourism.
