The easiest way to reach 3 Gilis on west of Lombok is from Bali both by flight or by sea. Flight from Bali is daily using small plane such as CN 25 with capacity 36 pax or Fokker 28 with the capacity of 50 pax. It needs 25 minutes flying from Bali to Mataram international airport. There are also international flight from Singapore direct to Mataram, but the frequency is still very small only twice a week, as well as from other cities of Indonesia such as Jakarta with stop in Surabaya only 4 times a week. From Mataram airport need to ride a car to small port called Bangsal on the west coast of Senggigi Beach from where one has to take motorized boat to reach the Gilis, with 15 minutes to the closest Gili Air, and 30 minutes to reach the farthest Gili Trawangan. By sea can be reached from Padangbai port in Bali by ferry boat takes between 4 to 5 hours to cross Lombok strait to the port of Lembar located on the south west of Lombok.
