Lisbon Day Trips: Sintra and Cascais by Rail
Get the station wrong and the day is over before it starts: the Sintra train leaves from Rossio, the Cascais train leaves from Cais do Sodre, and the two stations sit 1.2 km apart in different directions. Neither Sintra nor Cascais is Lisbon itself, whatever a same-day itinerary graphic implies; both are real train journeys with their own timetables, and treating them as neighborhoods costs people their afternoon.
Sintra, and the ticket that catches people out
CP trains leave Rossio Station for Sintra every 15 to 20 minutes, taking about 40 minutes each way for 2.45 EUR. The palace everyone comes for, Pena Palace, prices Palace plus Park at 20 EUR and Park-only at 10 EUR, and interior entry runs on strict timed slots tied to the palace doorway, not the outer gate; arrive late and the ticket is void, so allow a full 30 minutes to climb from the gate to the entrance. Quinta da Regaleira, the neo-Manueline estate with its spiral Initiation Well, costs 15 EUR and also uses timed online booking through its own ticketing site. Castelo dos Mouros, the 8th-century Moorish ramparts, is 12 EUR. Scotturb’s Bus 434 loops from the train station to the castle and Pena Palace for a 13.50 EUR day pass, cheaper bought online than from the driver; arrive at Rossio by 08:00 to beat the tour coaches. Book Pena Palace entry as part of a guided half-day tour if you’d rather skip the bus queue and the timed-entry booking altogether.
Cascais and Cabo da Roca
CP trains for Cascais leave from Cais do Sodre, running along the coast through Belem, Carcavelos, and Estoril in 33 to 40 minutes for 2.45 EUR. Cascais itself is a fishing town turned resort, with Praia da Rainha’s sand, a seawall walk out to the Boca do Inferno sea chasm, and the Casa das Historias Paula Rego art museum. From the Cascais bus terminal, Carris Metropolitana Bus 1624 runs about 25 minutes to Cabo da Roca, the westernmost point of mainland Europe, and continues on to Sintra if you want to link the two in one long day.
Why not do both in one day
Sintra and Cascais sit in different directions from Lisbon on different rail lines, and the bus connection between them eats hours that would otherwise go to actually seeing either place. Unless you’re on an organized small-group van tour built around that exact route, pick one per day. A full-day guided combination of Sintra, Pena Palace, and Cascais is the more realistic way to see both without losing half the day to bus transfers.
Current train timetables and fares for both lines sit on CP - Comboios de Portugal , and Sintra’s palace and park tickets, including the timed-entry rules, are managed through Parques de Sintra . For a plan covering the rest of your stay around these two excursions, see the multi-day trips guide .
Verdict: Sintra rewards an early start and a booked palace slot far more than a spontaneous one; Cascais rewards a slow afternoon and rewards nobody who tries to also fit in Cabo da Roca and be back for dinner.
One concrete tip: buy the Pena Palace timed entry ticket online before you leave your hotel, not at the gate, since walk-up slots for the popular midday hours are frequently gone by 10 a.m. in summer.
