The three Gili islands are located just outside the north west coast of Lombok, and is a great place for snorkeling and diving. Gili Air is closest to Lombok, Gili Meno and Gili Trawangan further out. Boats are leaving Lombok regularly for the different islands from the Bangsal village or Senggigi, it is also possible to rent your own boat to take you to the island you like. Also from Bali you can go by boat to the Gili islands.
South Lombok is the least populated and maybe the least accessible part of the island, except for the Kuta area which is more developed. The roads are often in a bad condition, especially in the wet season. There is not much public transportation here, it is best to have your own car with or without a driver. But if you like a challenge the southern coast can offer some of the best and whitest beaches on Lombok, located between high cliffs and mountains.
