As with any location you are unfamiliar with, it pays to be alert while traveling within large crowds, especially during the high season. Pickpockets can quickly pick you clean of your money or passport, quickly turning a dream vacation into a nightmare. A number of pickpocketings and thievery have been reported in Charles de Gaulle airport, in train stations such as Gare du Nord in Paris, and on the Number 1 Train line in Paris, which provides service to many tourist destinations such as the Arc de Triomphe and the Louvre.)

Make use of your hotel's safe to protect items such as any jewelry you might have brought with you (which, in reality, is best left at home), extra monies, credit cards, and passports. Keep your eyes and a hand on bags at all times, and do not leave your items unattended.

In addition, when traveling abroad, it is often easiest to travel with traveller cheques, which are easier to replace than cash or credit cards if stolen. Most major banks offer traveller cheques in euro denominations. Keep a copy of the front page from your passport, any tickets, traveler checque serial numbers, and any other important information in a location separate from the originals. You may also consider leaving a copy of these pages with someone back at home, whom you can contact if necessary if you get into trouble abroad or email a copy to yourself. These copies will come in handy if you are a victim of theft. Be sure to contact your embassy immediately if your passport is stolen.
