France is generally very safe. The main concerns in Paris are pickpocketing around major tourist sites (Eiffel Tower, Montmartre, RER B stations) and occasional bag snatching on metros. Keep bags in front, use inside pockets, and be vigilant in crowded areas.
Terrorism risk, while elevated since 2015, is managed by heavy security presence at landmarks. Political protests (manifestations) are common and usually peaceful but can disrupt transport. Check local news before large city visits.
