Yes — Lisbon is worth three or four days, and it rewards people who like to walk. Its best parts are free: the viewpoints, the old quarters and the river. It suits least those who cannot manage hills, and it is least worth it in November, the wettest month of the year.
Most answers to this question are a list of reasons to go. The honest version has two sides, because Lisbon is an excellent city for some trips and a frustrating one for others.
| Lisbon is worth it if you… | Think twice if you… |
|---|---|
| Like to explore on foot | Have limited mobility or need step-free routes |
| Want viewpoints, old quarters and the river | Want a beach city with the sand in town |
| Have three or four days | Have only one day and want Sintra too |
| Travel in June or September | Can only travel in November |
| Enjoy long, unplanned meals | Want tightly scheduled attractions |

Lisbon’s strengths are not the headline monuments. They are the things you do between them.

The disappointments are predictable, and most of them come from treating Lisbon like a flat city with a checklist.

This is the comparison most people are really making. Both are worth visiting; they suit different trips.
| Lisbon | Porto | |
|---|---|---|
| Days needed | 3, or 4 with Sintra | 3, or 4 with the Douro valley |
| Best day trip | Sintra, 40 min by train | Douro valley, 2 hours by train |
| Terrain | Seven hills | One steep slope to the river |
| Rain per year | 793.5 mm | 1,146.9 mm |
| Best months | June and September | June to September |
Rainfall figures are the 1991-2020 IPMA climate normals. With a week in Portugal, most people do both — three days in Porto and four in Lisbon.

The city is open all year, but the same trip is a different experience in different months. These are the 1991-2020 climate normals for Lisboa / Instituto Geofísico from IPMA.

Most of what makes Lisbon disappointing can be avoided with how the days are planned rather than where you go.


Yes, for three or four days, especially for travellers who like to walk. Its best parts — the viewpoints, Alfama and the river — are free. It suits least those who cannot manage hills.
Three days for the city and a fourth for Sintra. The how-many-days guide sets out what fits in each.
Neither is better; they suit different trips. Lisbon is larger with more day trips nearby, Porto is more compact and wetter. With a week, do both.
