After landing at Humberto Delgado Airport, allow roughly 45–75 minutes for baggage collection, the airport queue, and reaching your central Lisbon hotel. The metro is the cheapest option—about 25–35 minutes to the centre, usually under €2 with a rechargeable Navegante card—but a taxi or ride-hailing car is more comfortable with luggage and generally takes 20–30 minutes outside rush hour. Check in, freshen up, and keep the first afternoon deliberately light.
Walk downhill through Baixa to Praça do Comércio, Lisbon’s grand riverfront square. Spend about 45 minutes beneath the yellow arcades and along the Tagus waterfront; it is an easy orientation walk after travelling, with broad, mostly level pavements and plenty of places to pause. Late December sunsets are early, so this is best done soon after settling in rather than leaving it too late.
From the square, walk north through Baixa and uphill into Chiado—about 10–15 minutes—to A Brasileira, the historic café on Rua Garrett. Settle in for coffee and a pastry, budgeting €8–15 per person; service can be brisk and the café is popular, so do not worry if you need to wait briefly for a table. It is more atmospheric than tranquil, but perfect for a first taste of Lisbon’s literary café culture.
Continue uphill through Bairro Alto to Miradouro de São Pedro de Alcântara, roughly 10 minutes from A Brasileira. Aim to arrive before sunset, which is around 5:15 p.m. in December, for views across the rooftops toward Castelo de São Jorge. The terrace is usually relaxed at this hour, though the cobbled streets are steep and slippery in wet weather; comfortable shoes will make the evening much easier.
Finish at Time Out Market Lisboa in Cais do Sodré, walking downhill for about 15–20 minutes or taking the short metro ride from Baixa-Chiado. Give yourselves around 1½ hours and €20–35 per person for a casual dinner, choosing from several Portuguese stalls rather than committing to a formal restaurant. It can become crowded at peak dinner time, so arriving around 6:30–7:00 p.m. makes finding seats easier. Afterward, return to the hotel by metro, taxi, or a short walk if you are staying nearby; keep the rest of the night quiet so the trip begins gently.
Start with a slow breakfast at Zenith Brunch & Cocktails on Avenida da Liberdade, allowing about an hour for coffee and one of the restaurant’s generous brunch plates (€15–25 per person). It is a popular spot, so arriving close to opening is the easiest way to avoid a wait—especially on a Sunday. From there, take an unhurried 45-minute walk down Avenida da Liberdade, Lisbon’s elegant, tree-lined boulevard. Follow the patterned calçada pavements south toward Restauradores, pausing to browse the small shops and shaded benches rather than treating it as a straight march.
Continue by metro or taxi to Float in Spa in Saldanha for your main wellness break. Reserve the floatation session or relaxation treatment ahead of time; allow 1½–2 hours including check-in, changing, and a quiet few minutes afterward. A treatment generally costs roughly €50–100 depending on the option and duration. Afterward, walk or take a short taxi ride to the Gulbenkian Museum in Avenidas Novas, where two hours is enough for a thoughtful visit without rushing. Check the museum’s official holiday schedule before setting out, as opening arrangements can change around Christmas; the surrounding gardens are also ideal for a gentle reset if the weather is mild. From Saldanha, the museum is about 15–20 minutes on foot or a few minutes by taxi.
Finish at Solar dos Presuntos near Restauradores, one of Lisbon’s dependable addresses for traditional Portuguese cooking and seafood. Walk there from the museum in roughly 25–30 minutes, or take the metro from São Sebastião toward Restauradores if you would rather save your legs. Expect approximately €35–60 per person before drinks; reserve in advance, particularly for Sunday dinner. Keep the evening relaxed—this is a good place to linger over petiscos, grilled fish, or a regional meat dish rather than add another scheduled stop.
Leave central Lisbon around 8:30–9:00am for Cais do Sodré station, allowing about 20 minutes to reach the station plus time to buy or load your ticket. The CP Cascais Line ride takes roughly 40 minutes; a one-way fare is usually about €2.50–€3. Trains run frequently, but check the CP app or station boards that morning, especially if there are weekend engineering works. From Cascais station, it is an easy walk into the historic center. Spend about an hour wandering the whitewashed lanes around Rua Direita, browsing small shops, and following the waterfront toward Praia dos Pescadores. The center is compact, so there is no need to rush between sights.
Continue on foot toward Cascais Marina, about 10–15 minutes from the old town. The harbor is best enjoyed slowly: stroll past the boats, look back toward the old fortifications, and take a short coffee break if you feel like it. This is a relaxed stop rather than a major sightseeing commitment, and it gives you a pleasant transition before lunch.
For lunch, settle in at Baía do Peixe overlooking Cascais Bay. Allow around 90 minutes for seafood, with a realistic spend of €25–45 per person depending on what you order. December can be breezy, so request a sheltered terrace table or sit indoors by the windows. After lunch, take a taxi or Bolt to Boca do Inferno—usually about 5–10 minutes and approximately €5–10, depending on demand. Walking is possible, but the route takes around 25 minutes each way and is less appealing if the weather is wet or windy.
Give Boca do Inferno about an hour. The path along the cliffs is straightforward, but stay behind barriers and expect spray on rougher days; the Atlantic swell is often most dramatic in winter. Return to the old town by taxi or local bus, then stop at Santini Cascais for gelato, typically €5–10 per person. It is a good final treat before returning to your hotel, with time afterward to rest rather than adding another attraction. For the trip back, walk to Cascais station and take a direct train to Cais do Sodré; allow about an hour door-to-door, including the walk from the station on the Lisbon side.
Start at Casa da Guia, on Cascais’s western edge, where the oceanfront path around the old lighthouse area is quieter than the centre and especially atmospheric in winter. Give yourself about an hour for the sea views and a coffee stop if something is open; December can be breezy, so bring a windproof layer. From here, continue west to Praia do Guincho—a taxi takes roughly 15 minutes, while a rental car is easier if you want flexibility. Expect dramatic surf and plenty of wind rather than swimming conditions, and allow around 1½ hours for a relaxed beach walk. Taxis are the practical choice for the return to Cascais or the short onward hop to lunch; agree on pickup timing, as service is thinner around the beach in the off-season.
Have a leisurely seafood lunch at Furnas do Guincho, near the beach, budgeting approximately €30–50 per person. Reserve ahead for a December visit and confirm the restaurant’s seasonal hours, since coastal venues sometimes shorten their schedule in winter. After lunch, take a taxi—about 10–15 minutes—to Sheraton Cascais Resort in Quinta da Marinha for your main relaxation session. Book the treatment or thermal-style facilities in advance and verify exactly what is operating on your date; spa access, pools, saunas, and treatments may have separate requirements or limited hours. Allow two hours without rushing, plus a little time to change and travel back toward town.
Return to central Cascais for a gentle final walk through Parque Marechal Carmona, whose shaded paths and landscaped gardens make a pleasant reset after the exposed coastline. Allow about 45 minutes, checking the seasonal closing time before setting out. Finish at Hemingway Cascais by the marina for cocktails or a light dinner, approximately €25–45 per person. The marina is an easy 10–15-minute walk from the park, though a short taxi ride is preferable if the wind picks up; reserve a table if you want harbor seating, and keep the evening unhurried rather than adding another attraction.
