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 scantily 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 clamours for attention.
