Should you be on a tram, possibly near Neptu, watch for suspicious-looking people, perhaps someone carrying a coat even though it is very hot. If anyone gets too close to you, be aware they may be about to pick your pocket. Since you are in a confined space, they may persist in trying to get very close to you. Even though you try to move away or try to get off at the next stop saying "Salida" in a loud voice.

Pay attention to the announcements over the Tannoy at most stations, warning of pickpockets, since they can be so professional, they could remove cash from a tightly zipped front pocket.

Despite this Valencia is a good city, clean, interesting, good food, nice people, affordable prices. Just be careful with personal possessions.
