One of the approximately 14,000 islands that comprise the Indonesian archipelago, Bali anchors east of Java, separated by the small Strait of Bali, and surrounded by the Java Sea on the north, the Indian Ocean on the south, and the Strait of Lombok on the east. A string of volcanic mountains crown the northern part of Bali, with Gunung Agung (Mount Divine, literally) as the tallest at 3,142 meters. This volcano, as well as Mount Batukaru, Mount Batur, and Mount Merebuk is still active.

Extremely important to the agricultural life of Bali, especially for rice crop, the rivers of Ayung, Unda, Sungsang, Balian, Yeh Sumi, Petanu, and Saban carry the water from the highland to the seas. There are four major lakes: Lake Batur at the crater of Mount Batur, Lake Buyan, Lake Bratan, and Lake Temblingan.

Bali enjoys tropical weather, being only a few degrees south of the equator. It means that the sun rises at 6 AM in the morning and sets at 6 PM in the afternoon, everyday of the year. It means that temperature variation is very small, averaging around 26-30 Celcius, and it does not have four seasons (except the hotel, of course). It only has a wet season, typically from September to February, and a dry season for the other half of the year. But the difference is marginal; at the peak of the wet season you will see about a half-hour to an hour serious downpour in the afternoon, about perfect for a siesta. The rest of the time: nice, warm temperature, especially with a twist of sea breeze in the beaches of Kuta or Nusa Dua.

This climate endows Bali with a number of unique vegetation, including waringin trees (banyan), salak Bali, and a multitude of flowers from a very fragrant cempaka (Michelia champaca) to literally thousand kinds of orchids. Its fauna is equally rich. Bali is the native land to the Bali Tiger, which is almost extinct; Bali cattle, graceful animals not like other cows; bats that haunt caves like the Bat Cave near Kusamba; sea turtles of Nusa Dua; Jalak Bali or Bali Sterling (Leucopsar rothschildi) that has inspired countless number of painters and artists.
