Health care system in Portugal is at good European standards.
European Union citizens, holder the European Health Insurance Card (EHIC), receive free medical health care. Other nationals are recommended to purchase medical insurance before visiting Portugal. Doctors and hospitals often expect up-front payment for services.
Tap water is considered safe to drink, but may be heavily chlorinated in some parts of the country, so for better taste use bottled water.
Portugal is generally safe for tourists and has a relatively low rate of violent crime.
Travelers should be aware of potential petty crime dangers - pickpockets and bag-snatchers are more active at popular tourist sites and on public transport and stations (Lisbon metro being probably the worst).
Car break-ins involving rental cars or cars on foreign licence plates can also be a problem.
