Gili T grew fast. By one estimate, visitors rose from about 35,000 in 2009 to more than a million in 2015, and the party reputation it earned in the 1980s and 1990s has never quite left: the bars on the east-coast strip take turns hosting a late party, and mushroom shakes are still advertised, illegally. But the crowd is now just as likely to be divers, families and couples, who stay on the quieter north and west coasts.
The infrastructure shows the strain. Power arrives by undersea cable from Lombok, backed by a 600 kWp solar plant, and cuts of a few hours still happen at peak times. Water is the bigger problem: piped water comes from a seawater desalination plant, and when it failed on 3 September 2026 the island went without for days and about 300 tourists checked out early. Gili T produces 7 to 8 tonnes of rubbish a day, up to 16 tonnes in holiday weeks. The August 2018 Lombok earthquake damaged buildings here too, though the worst of it hit the mainland.
About 2,000 people live on Gili T, mostly Muslim Sasak, and the call to prayer carries across the island. Dress modestly away from the beach, especially in the village and during Ramadan.
Choosing the island matters more than choosing the hotel. Gili T has the most of everything, from dive shops to nightlife. Gili Air, closest to Lombok, is a calmer, lived-in village with good snorkeling and a weekly party rather than a nightly one. Gili Meno, in the middle, is the quietest, with the Nest statues and a salt lake. Compared with Nusa Penida, the Gilis are flat and easy: no cliff stairs or rough roads, just sand paths and water.
