How should you spend four days in Lisbon?
Give Lisbon three days and keep one for a day trip. Walk downhill through Alfama on day one, spend day two in Belém, take day three slowly around Chiado and Príncipe Real, then choose Sintra for palaces or Cascais for a coastal day. You do not need to see both on a four-day visit.
If day two falls on Monday, swap it with the central-city day: Jerónimos Monastery closes Mondays. This route assumes four usable days, rather than a morning arrival and an early departure.
The plan
Lisbon looks compact on a map, but the hills change what fits comfortably. Group stops by neighborhood and take transport uphill when it saves your legs. Belém is its own outing west of the center, not a quick detour between Alfama and Chiado. The fourth day is a choice about your energy: a palace day in Sintra is rewarding but structured; Cascais is easier to improvise.
Day one: Baixa, São Jorge Castle and Alfama
Start in Baixa, then take a tram, bus or car up toward São Jorge Castle. Whether you go inside depends on how much you want the ramparts and views; the better route decision is to begin high and walk down. Follow the lanes through Alfama, stop at a miradouro that catches your eye, and come out near the cathedral or the river. Do not schedule a second cross-town monument that afternoon.
For a proper Portuguese lunch, O Velho Eurico in Mouraria is a lively choice if you can get a table. For a seafood dinner, Cervejaria Ramiro is farther north in Intendente, so make it the evening's destination rather than pretending it is around the corner from Alfama. If you want to stay close, eat wherever the walk ends and save Ramiro for another night.
Day two: Belém, with lunch worth staying for
Go straight to Jerónimos Monastery in the morning if seeing the cloister matters to you. It closes Mondays and tickets can sell out. Walk to Pastéis de Belém for a warm tart, then decide whether you want more history or contemporary art. Belém Tower is a good riverside stop; MAAT gives you a different kind of afternoon and is closed Tuesdays.
Have lunch here rather than commuting back hungry. O Frade, by Ajuda, is the pick for Alentejo cooking and duck rice. Canalha, on Rua da Junqueira near MAAT, is livelier and better if you are continuing along the waterfront. They suit different routes, so choose the one that matches your afternoon. The Belém guide covers what to skip if you only have half a day.
Day three: Chiado and Príncipe Real
Let this be the day that feels like being in Lisbon rather than completing Lisbon. Start around Chiado's bookshops and cafés, then work up to Príncipe Real. Browse Embaixada, a collection of shops inside Palácio Ribeiro da Cunha, and take a break in the garden opposite. If you still want another neighborhood, continue toward São Bento or Estrela. Otherwise, stay put.
Pica-Pau on Rua da Escola Politécnica is an easy lunch for Portuguese classics. After dinner, Cinco Lounge is a nearby cocktail stop with a long-standing bar program. The Chiado versus Príncipe Real guide helps if you want to give one area more time.
Day four: choose Sintra or Cascais
Choose Sintra if palaces and gardens are a reason for coming. Take the train from Rossio, then use local transport uphill. Book the Pena Palace interior time before arranging the rest of the day. The park entrance is below the palace; the operator advises allowing about 30 minutes to reach the interior entrance, and the timed slot is strict. Add one more major sight at most, then stop in Sintra town for a travesseiro at Piriquita.
Choose Cascais if you would rather spend the day by the water with fewer bookings. Take the Cascais line from Cais do Sodré, walk the center and seafront, and have a long seafood lunch. Do not attempt to turn Sintra and Cascais into one public-transport day. For a closer comparison, read Sintra or Cascais; for the palace route, use the Sintra day-trip guide.
Where to stay for this route
Chiado makes the central days easy and gives you a straightforward starting point for either train station. Príncipe Real is better if you want a calmer base and expect to spend evenings around its restaurants and bars. Belém is lovely to visit, but it is less convenient as a base for this particular four-day route. The Lisbon hotel guide compares specific properties and their feel, not just their map pins.
What to book before you go
Book Pena Palace first if you choose Sintra, then Jerónimos for a day it is open. Reserve the restaurant you would regret missing; keep the rest of the meals flexible. Check live train service and monument hours shortly before travel. The Lisbon booking guide has the current ticket decisions in one place.
