Three days in Lisbon in October. I would rather walk than take transport, but I do not want 25 km days.
ChatGPT
Lisbon punishes naive routing because the hills are steep and the distance on the map is not the distance in your legs. A workable split:
| Day | Area | Walking | Climb |
|---|---|---|---|
| 1 | Baixa, Alfama, Graça | 8 km | 210 m |
| 2 | Belém, riverside | 9 km | 40 m |
| 3 | Príncipe Real, Bairro Alto | 7 km | 180 m |
Day 2 is flat on purpose, so put it in the middle rather than at the end.

Is the tram worth it or is it a tourist trap?
ChatGPT
Both. Tram 28 is genuinely the easiest way up to Graça, and it is also packed enough that pickpocketing is a real risk in the middle of the day. Taking it uphill early, walking down, and skipping it entirely after noon gets you the useful half without the queue.
