Most visitors to Poland experience no difficulties. But you should be alert to the possibility of street crime and petty theft, and that foreigners may appear to be lucrative targets as in any other country in Europe.
Keep valuables and cash out of sight, especially in crowded areas and tourist spots where pickpockets and bag snatchers operate. There is a higher risk of robbery at main rail stations and on all train services, especially overnight sleeper trains. You are most at risk while boarding and leaving trains.
Unregulated taxi drivers operate at the Warsaw airports and elsewhere. They commonly overcharge. Only use official taxis, which have the name and telephone number of the taxi company on the side of the door and on the top of the taxi. They will also show a rate card on the window of the vehicle. Taxis with a crest but no company name are not officially registered taxis.
Don’t leave drinks or food unattended and beware of accepting drinks from casual acquaintances. There have been a small number of reports of drinks being spiked and visitors having their valuables stolen.
