Cascais day trip guide
A former royal seaside retreat with an easy train ride, a walkable old town, and Lisbon's most convenient beach day.
Why Cascais is worth the trip
Cascais spent centuries as the Portuguese royal family's seaside retreat, and it still carries that unhurried, well-kept feel — a working marina, a walkable old town of low pastel buildings, and a run of beaches that starts right at the edge of the centre. It's the easiest genuine beach day out of Lisbon, and pairs naturally with neighbouring Estoril on the same train line.
Getting there
Direct trains run from Cais do Sodré station roughly every 20 minutes, taking about 40 minutes and hugging the coastline for most of the ride — genuinely scenic in its own right, with sea views for the second half of the journey. Buy a ticket or tap a Viva Viagem card at the station before boarding. Estoril is one stop before Cascais on the same line, so it's easy to visit both in a single day.
The beaches
Praia da Rainha and Praia da Ribeira sit right in the town centre — small, convenient, and busy in season, best for a quick dip rather than a full beach day. Praia do Guincho, a 20-minute bus or taxi ride further along the coast, is a wide, wind-exposed Atlantic beach popular with surfers and considerably less crowded, though the water is colder and the currents stronger — check conditions before swimming.
What else to do
Boca do Inferno. A dramatic sea cave where Atlantic swells crash into a collapsed cliff cavern, a short walk or taxi from the centre — best visited on a day with real swell for the full effect.
The old town. Cascais' historic centre is compact and genuinely pleasant to wander — cobbled streets, a covered market, and a waterfront promenade linking the marina to the beaches.
Estoril Casino. One of Europe's largest casinos, a short walk or one train stop from Cascais, with gardens out front worth a look even without gambling.
Cabo da Roca. Continental Europe's westernmost point, a dramatic clifftop roughly 30 minutes further by bus or taxi — worth combining with Cascais if you have a car or are comfortable with local buses.
Cascais or Sintra — which one?
They solve different problems. Sintra is about architecture and palaces, is busier, and needs a full day to do properly. Cascais is lower-key, works well as a half-day or a full lazy beach day, and is the better choice if you'd rather trade sightseeing density for time by the water. Doing both on the same trip is common, just not on the same day — they're on opposite train lines from different Lisbon stations.
Combine with Estoril
Estoril is one stop before Cascais on the same line and walkable between the two along the coastal promenade in about 30–40 minutes — an easy way to see both without extra transport.
Practical tips
- Bring a beach layer even in summer — coastal wind here is noticeably stronger than in central Lisbon.
- Praia do Guincho's waves and currents suit experienced swimmers and surfers better than casual dips; the town-centre beaches are calmer.
- The coastal train ride itself is worth the trip — sit on the right-hand side heading out from Cais do Sodré for the best sea views.
