Gili Trawangan is a tropical playground of global renown, ranking alongside Bali and Borobudur as one of Indonesia's top destinations. Trawangan's heaving main drag, busy with bikes, cidomos and mobs of swimwear-clad visitors, can surprise those expecting a languid island retreat. Instead, a bustling string of lounge bars, hip guesthouses, ambitious restaurants, convenience stores and dive schools clamors for attention.
