Use of common sense is required, as in any large city. The central parts of cities are renowned for petty crime, (pickpocketing, scams or bag snatching) so be careful when sightseeing, taking pictures or watching street artists. You should be extra vigilant at airports and railway stations, as well as in the Metro. Do not leave valuables unattended. Most shops accept credit and debit cards, so there is no need to carry a lot of cash.


The French law, in accordance with Regulations in force in most European Countries, does not allow smoking in any public transportation or in any closed public areas. Non-compliance with this ban can lead to a fine of up to 450 Euros.
