Relaxed Gili Air stretches about 1.5km in each direction and takes a couple of hours to walk round. It’s a pleasant cross between lively, social Gili Trawangan and peaceful Gili Meno; however as there’s no more land available on Gili Trawangan, the island is, sadly, becoming increasingly developed. Although accommodation is spread around most of the coast, it’s concentrated on the southeast and northeast corners.
The beach in the southeast corner is popular, with good snorkelling. Snorkelling gear is widely available for rent; try Ozzy’s Shop on the east coast. For snorkelling further afield, boat trips are advertised pretty much everywhere and take in sites off all three islands.
