Lombok is to the east of Bali and it is not without good reason that we call it untouched Bali ”. With beautiful beaches, enchanting waterfalls, the tall, towering Mount Rinjani volcano, and relatively few visitors, Lombok is indeed the tropical island paradise that many people still mistake for Bali. Lombok and Bali are separated by the Lombok Strait. The Lombok Strait is also part of the biogeographical boundary between the fauna of Indo-Malaysia and the distinctly different fauna of Asia. The border is known as the Wallacean Line, after Alfred Russell Wallace who first noticed the difference between animals from Indo-Malaysia and those from the rest of Asia.
