Indonesia ("Indian island world"), the third largest state in Asia (after China and India), known for its tropical destinations with white sand beaches and blue sky imagery. Beach resorts and hotels were developed in some Indonesia islands, with Bali island as the primary destination. Cultural tourism is also an important part of Indonesia tourism industry. Toraja, Prambanan and Borobudur temples, Yogyakarta and Minangkabau are popular destinations for cultural tourism, apart from many Hindu festivities in Bali.

Indonesia has a well-preserved, natural ecosystem, such as rainforests that stretch over about 57% of Indonesia's land. Forests on Sumatra and Java are examples of popular tourist destinations. Moreover, Indonesia has one of longest coastlines in the world, with a number of beaches and island resorts, such as those in southern Bali, Lombok, Bintan and Nias Island.

Dive sites

With more than 17,000 islands, Indonesia presents ample diving opportunities. Bunaken, at the northern tip of Sulawesi, claims to have seven times more genera of coral than Hawaii, and has more than 70% of all the known fish species of the Indo-Western Pacific. Moreover, there are over 3,500 species living in Indonesian waters, including sharks, dolphins, manta rays, turtles, morays, cuttlefish, octopus and scorpionfish, compared to 1,500 on the Great Barrier Reef and 600 in the Red Sea. Other popular dive sites on Bali are at Candidasa and Menjangan. Across the Badung Strait from Bali, there are several popular dive sites on Nusa Lembongan and Nusa Penida. Lombok's three Gilis (Gili Air, Gili Meno and Gili Trawangan) are popular as is Bangka.

Surfing

Surfing is also a popular water activity in Indonesia and the sites are recognised as world class. The well-known spots are mostly located on the southern, Indian Ocean side of Indonesia, for example, the large oceanic surf breaks on southern Java. Surf breaks can be found all the way along Sumatra, down to Nusa Tenggara, including Aceh, Bali, Banten, Java, Lombok, the Mentawai Islands, and Sumbawa. On Bali, there are about 33 surf spots. Sumatra is the second island with the most number of surf spots, with 18 altogether. The common time for surfing is around May to September with the trade winds blowing from east to south-east. From October to April, winds tend to come from the west to north-west, so the east coast breaks get the offshore winds.
