Money
A guide to Gili Trawangan reminds visitors the island genuinely has no cars or motorbikes, a law rather than just a marketing angle, so getting around means walking, cycling, or riding a horse-drawn cidomo cart instead. Their money tip: bring enough cash for daily needs, since most places on the island don't accept credit cards, and bike rentals run around 50,000 IDR for 24 hours, cheap enough to make cycling the default way to explore beyond your immediate stretch of beach.
