Sintra and Cascais sit on the same coast west of Lisbon, and together they make one of Portugal's best short trips: a hill of Romantic palaces and a seaside town with cliffs, beaches and seafood. They are very different places, so plan them as two halves of one trip rather than one rushed day.
What to book ahead
The one thing that cannot be left to chance is Pena Palace. Palace entry is sold for a specific date and time slot, each ticket allows one entry, and online tickets can be changed until 6 pm the day before. Fast-track tickets have no delay tolerance, so if you miss your slot you lose the visit. Book Pena first, then plan the rest of your day around it. Quinta da Regaleira uses half-hourly entry slots with a one-hour grace period, so book that too in busy seasons. The Moorish Castle, Monserrate and the National Palace are easier, but it is still worth buying online and skipping the queue. All of the Parques de Sintra monuments close on 24, 25 and 31 December and 1 January.
Check the status of what you plan to see
Monserrate Palace is under roof restoration until the first quarter of 2027, with scaffolding and a temporary covering, though the park and palace remain open. At Cabo da Roca, a lighthouse interpretation centre opened to the public on 23 July 2026, with a self-guided Essential Visit and a Panoramic Visit that climbs to the balcony.
How to get around
From Lisbon, take the CP train on the Sintra line from Rossio, Oriente or Entrecampos to Sintra, then use the Scotturb bus 434, which links the station, the village, the Moorish Castle and Pena. Bus 435 serves the National Palace and Monserrate, and route 1253 also reaches Monserrate. Private cars cannot go up to Pena, and driving into the historic centre is limited to residents, so leave the car at a car park or skip it. To reach Cascais, the commuter train from Cais do Sodre runs along the coast in under an hour. Between Sintra and Cascais, use a taxi or a bus, and for Cabo da Roca take a taxi, a tour or a Scotturb bus, checking the timetable in advance.
How many days
Two nights is the right amount. Spend a full day in Sintra with Pena in the morning and Regaleira or the National Palace in the afternoon, a second morning on the Moorish Castle or Monserrate, then move to the coast for Cabo da Roca, Boca do Inferno and an evening in Cascais. If you only have one day, a guided small-group trip covers the headlines, but you will not see any one place in depth. Three days lets you add Monserrate and a slow afternoon on the beach.
A simple plan
Day one: take an early train to Sintra, climb to Pena for your morning slot, walk or bus to the Moorish Castle, lunch in the village and finish at Regaleira. Day two: do the National Palace in the morning, then travel to the coast by taxi or bus, visit Cabo da Roca, and spend the evening in Cascais with a walk to Boca do Inferno at dusk.
Practical tips
Wear sturdy shoes, because the hills and cobbles are tiring. Carry a light layer, since Sintra's hills are often cooler and misty. Start early in summer, when the palaces are busiest from late morning. Winter brings rain and wind, but the crowds are smaller and the waves at Boca do Inferno are impressive. Boca do Inferno itself is a free public viewpoint, so stay behind the barriers in rough weather.
Where to stay
If you want to see the palaces at opening time, stay in Sintra, at a palace hotel such as Tivoli Palacio de Seteais or a historic boutique like Lawrence's Hotel. If you prefer sea air and easy rail access to Lisbon, stay in Cascais, at Farol Hotel on the waterfront, or at the Cascais Miragem on the Estoril coast. A budget guest house in Sintra is a good compromise for a night.
