Due to its location and geology, Indonesia has a very diverse landscape, from fertile rice paddies on Java and Bali to tropical rain-forests in Sumatra, Kalimantan and Sulawesi. The Nusatenggara islands have savannah grasslands and West-Papua even features snow-capped mountains. Wildlife is versatile including the prehistoric Komodo lizard, Orang Utans, Java rhinos, Sulawesi anoa dwarf buffalos, and rare-, exquisite birds such as the cockatoo and the bird of paradise.
When diving in Indonesia it is mostly a matter of choices and priorities. The most well-known islands are Sumatra, Java, Bali, Kalimantan (formerly Borneo), Sulawesi (formerly Celebes), the Maluku Islands (aka Moluccas; the original Spice Islands) and Papua, but there are also many unexplored islands.
