Bali is an island and the smallest province of Indonesia, and includes a few smaller neighbouring islands, notably Nusa Penida. It is located at the westernmost end of the Lesser Sunda Islands, between Java to the west and Lombok to the east, and has its capital of Denpasar at the southern part of the island.
With a population of 3,890,757 in the 2010 census, and currently 4.22 million, the island is home to most of Indonesia's Hindu minority. According to the 2010 Census, 84.5% of Bali's population adhered to Balinese Hinduism, 12% to Islam, and most of the remainder followed Christianity. Bali is also the largest tourist destination in the country and is renowned for its highly developed arts, including traditional and modern dance, sculpture, painting, leather, metalworking, and music. A tourist haven for decades, the province has seen a further surge in tourist numbers in recent years.
The island of Bali lies 3.2 km (2 mi) east of Java, and is approximately 8 degrees south of the equator. Bali and Java are separated by the Bali Strait. East to west, the island is approximately 153 km (95 mi) wide and spans approximately 112 km (69 mi) north to south; administratively it covers 5,780 km2, or 5,577 km2 without Nusa Penida District, its population density is roughly 750 people/km2.
Bali's central mountains include several peaks over 3,000 metres in elevation. The highest is Mount Agung (3,031 m), known as the "mother mountain" which is an active volcano. Mountains range from centre to the eastern side, with Mount Agung the easternmost peak. Bali's volcanic nature has contributed to its exceptional fertility and its tall mountain ranges provide the high rainfall that supports the highly productive agriculture sector. South of the mountains is a broad, steadily descending area where most of Bali's large rice crop is grown. The northern side of the mountains slopes more steeply to the sea and is the main coffee producing area of the island, along with rice, vegetables and cattle. The longest river, Ayung River, flows approximately 75 km.
The island is surrounded by coral reefs. Beaches in the south tend to have white sand while those in the north and west have black sand. Bali has no major waterways, although the Ho River is navigable by small sampan boats. Black sand beaches between Pasut and Klatingdukuh are being developed for tourism, but apart from the seaside temple of Tanah Lot, they are not yet used for significant tourism.
