7 guides, each rated 1 to 5 with the reason — and two lists per place, where you are comfortable and where to pay attention. Nowhere is called dangerous; the specific thing is what helps.
Very safe. The problem here is numbers: Pena sells timed tickets and they go, the 434 bus queue can be an hour in August, and the hill road is single track with coaches on it. Go early, buy ahead.
Comfortable: the historic centre · the palace grounds · São Pedro · Cascais
the hill road in season — single track with coaches on it and a two-hour bus queue in August
the forest paths in mist — the hill makes its own cloud and visibility drops fast
the cliffs at Cabo da Roca — unfenced in places, with a long way down
One of the safest coastlines in Europe. What hurts people here is the sea and the cliffs: strong Atlantic currents, undertow at the west-coast surf beaches, and sandstone cliffs that collapse without warning — the signs telling you not to sit under them are not decorative.
Comfortable: Lagos · Tavira · Carvoeiro · Faro
Albufeira Strip — at closing time, which is the one place here with any trouble
The cliffs, which are sandstone and collapse without warning — the signs are not decorative
Praia do Amado — and the west coast, where the Atlantic undertow is serious and lifeguards are seasonal
Hire-car break-ins at beach car parks and trailheads
Very safe with almost no street crime, and Funchal is comfortable at any hour. The hazards are the terrain: levada paths run along unfenced drops and several people are killed on them each year, usually in fog or in the wrong shoes. Check whether a route needs a head torch for tunnels. The sea on the north coast is rougher than it looks.
Comfortable: Funchal old town · Lido · Câmara de Lobos · Monte
the levada paths in fog — unfenced drops, and the cloud comes in fast
the north coast sea — rough and with currents, even where it looks calm
Extremely safe and very quiet. Everything difficult here is weather: fog closes the crater viewpoints without warning, inter-island flights are cancelled often enough that a tight connection is a bad idea, and the Atlantic swimming is cold and has currents. Trails after rain are mud on volcanic rock.
Very safe. The roads are narrow, steep and have unfenced drops to the river, and the tastings mean somebody in the car must not be drinking — the police check the valley roads in the harvest weeks.
Comfortable: Peso da Régua · Pinhão · Lamego · the quintas · the river cruises
the valley roads — steep, narrow, unfenced above the river and full of hire cars in the harvest weeks
driving after a tasting — the police check these roads and somebody has to stay dry
the heat in the gorge in high summer — it sits between the walls and does not move
Very safe. Watch your footing on wet cobblestones on the steep streets, and be careful of the crowds on the Luís I bridge upper deck.
Comfortable: Ribeira · Baixa · Foz do Douro · Cedofeita
São Bento station — and tram 1, for pickpockets
Campanhã — the station area at night
