Local Tips for Lisbon

✓Tram 28 and crowded Metro carriages are pickpocket hotspots — keep valuables secure, wear bags in front, and stay alert when boarding and alighting
✓Lisbon's steep, hilly streets are paved with slick 'calçada portuguesa' cobblestones that get very slippery in the rain — wear sturdy shoes with good grip
✓Alfama, Bairro Alto, and Cais do Sodré are generally safe but get crowded and lively at night — keep to well-lit main streets and watch your drink in bars
✓Politely decline the men who openly offer 'hash' or 'cocaine' to tourists in Baixa and along the riverfront — it is a well-known scam (the product is usually fake) rather than a violent threat, but just walk on
✓112 is the all-purpose EU emergency number for police, ambulance, and fire, and operators speak English; the SOS Voz Amiga and tourist support lines can also help if you need non-emergency assistance
✓Portuguese people are friendly and English is widely spoken in central Lisbon — don't hesitate to ask shopkeepers or café staff for directions or help
