Gili Trawangan is the largest among Lombok's Gili Islands and is the only one to rise significantly above sea level. Gili simply means "small island" in Sasak language. Geographically, it is only 3km long and 2km wide with a population of about 1000. Of the Gilis, Trawangan has the most tourist facilities; the pub Tîr na Nôg claims that Trawangan is the smallest island in the world with an Irish pub. The most crowded part of Trawangan lies on the eastern side.
On Gili Trawangan, there are no motorized vehicles. The main means of transportation are bicycles (rented by locals to tourists) and cidomo (a small horsedrawn carriage). For traveling to and from each of the Gilis, locals usually use motorized boats and speedboats.
Some of the first inhabitants of Gili Trawangan were from Sulawesi who are fishermen and farmers. Previously Gili Trawangan was covered in forest and deer lived on the island.
