Bali

Indonesia's spiritual heartland spans 5,780 sq km and rises to the sacred Gunung Agung volcano at 3,142m, last erupting in 2017-2019. Bali's 20,000 temples, UNESCO-listed subak rice terrace irrigation system dating to the 9th century, world-class surf breaks at Uluwatu, and vibrant arts scene in Ubud make it the world's most visited tropical island with 6.3 million arrivals annually.
