Gili Trawangan is the largest of Lombok’s Gili Islands and the only one to rise significantly (30 m) above sea level. Measuring 3 km long and 2 km wide, it has a population of around 1500.
The name Trawangan originates from the Indonesian word Terowongan (Tunnel) due to the presence of a cave tunnel built there during Japanese occupation in World War 2. Of the Gilis, Trawangan is the most developed and geared towards tourism. The main concentration of settlement, recreation, accommodation and diving business is situated on the eastern side of the island. A local pub, Tîr na Nôg claims that Trawangan is the smallest island in the world with an Irish pub. It was previously administered under Lombok Barat Regency along with Senggigi until 2010 when the Gili islands came under the jurisdiction of the new North Lombok Regency (Kabupaten Lombok Utara).
On Gili Trawangan (as well as the other two Gilis), there are no motorised vehicles. The main means of transportation are bicycles (rented by locals to tourists) and cidomo (a small horse-drawn carriage). For travelling to and from each of the Gilis, locals usually use motorised boats and speedboats.
Some of the first inhabitants of Gili Trawangan were fishermen and farmers from Sulawesi. Previous to human settlement Gili Trawangan was covered in forest and deer lived on the island. (Source: Inhabitants of Gili Trawangan — no printed source available).
The economy of Gili Trawangan centres on tourism, as the island is too small to support any broad scale agriculture, and too remote to allow economically viable industry or commerce. There is a mosque on the island.
