What to plan for—not a blanket safety claim
- Keep passport, cards and cash in separate places; keep a copy of the passport photo page.
- Treat crowded trams, Metro cars and stops as higher-attention moments for valuables.
- Buy and keep sight of your own drink; decide the return route before a late-night venue.
- Monitor strikes, demonstrations, heat and wildfire notices when they affect your route or day trip.
- Use the official taxi rank or signed TVDE pickup area at the airport; reject unsolicited approaches.
Night context without a dangerous-area list
The guidance does not support naming a blanket 'dangerous district.' Risk is contextual: crowded transport raises theft exposure, and official UK advice says attacks including sexual assault are rare but do occur, with higher risk late at night around popular nightlife locations.
Emergency help
Call 112 for police, ambulance or fire. It is the free European emergency number. For a non-emergency police station, use the current PSP Lisbon directory rather than an undated third-party list.
