Three days is enough for Lisbon, and a fourth is for Sintra. Give each day one or two hills rather than crossing the city twice — Alfama and the castle on one, Baixa and Chiado on another, Belém on a third. Go between March and May or in September and October: July and August bring both the heat and the longest queues.
Lisbon is spread across seven hills and the walk between two of them is often steeper than the map suggests. The single most useful planning decision is to group each day around one hill and come down only once.
The funiculars and the Santa Justa lift are not sightseeing — they are how the city moves people up hills, and using them as transport rather than as an attraction is what saves the legs.
Belém holds the two UNESCO monuments and the most famous custard tart in Portugal, all within about a kilometre of each other along the river.
The queue outside Pastéis de Belém is the takeaway queue. The sit-down rooms inside run deep into the building and are usually far emptier — walk in past the line, ask for a table, and you will often be served faster than the people standing outside.
Every guide to Lisbon recommends Tram 28, and almost none of them mention what riding it is actually like in season: a queue of forty minutes at Martim Moniz, then a full carriage, standing, with your bag in front of you.
If the point is the view rather than the tram, walking down through Alfama gives you the same streets at your own pace, and you can stop.
A miradouro is a public terrace built where a hill drops away. Lisbon has dozens, they cost nothing, and collectively they are the thing visitors remember.
Sintra is about forty minutes by train from Rossio station, and almost every itinerary underestimates it. The palaces are spread across a wooded hillside, the shuttle bus between them is slow, and the main sites use timed entry.
| Where | One way | What it needs |
|---|---|---|
| Sintra | 40 min by train from Rossio | A full day, and timed tickets booked ahead |
| Cascais | 40 min by train from Cais do Sodré | A half day; a beach town, walkable from the station |
| Setúbal | 1 hour | A half day, for the market and the ferry across the estuary |
| Évora | 1.5 hours | A full day; Roman temple and a walled centre |
If you only have three days in total, Sintra is the thing to cut. Half a day there is worse than not going: you will spend it queueing and travelling rather than seeing anything properly.
Three days covers the city without rushing: one for Alfama and the castle, one for Baixa and Chiado, one for Belém. Add a fourth if you want Sintra, which needs a full day of its own.
Only if you board at Campo de Ourique, the far end, where there is usually no queue and you can get a seat. From Martim Moniz in summer it is a forty-minute queue for a crowded standing ride through streets you can walk.
March to May and September to October. The weather is warm without being heavy, and the queues at Belém and Sintra are a fraction of the July and August ones.
It pays off if you are visiting Jerónimos, Torre de Belém and using public transport heavily on the same day. For a slower trip built around miradouros and walking — which is most of Lisbon — it does not.
Yes for the palaces, which use timed entry and sell out in season. The town and the hillside walks need nothing booked.
