For as long as there have been travellers, there have been travel scams. There are some classics that have been going on for years and continue to fool tourists, but as word spreads on certain ruses, they either fade away or evolve into new scams.
To help you keep track of the latest scams out there, this website, Scams Travel, maps various scams encountered by travellers. Been scammed? Add your own to the list? Are you a scammer? I suppose this list will help you add new ones to your repertoire, but we also hope you go to jail.
