Worth half a day

Our verdict

Is Cascais worth a day trip from Lisbon?

Half a day is enough.

Go for half a day, not a whole one. The train from Cais do Sodré takes 40 minutes, 33 on the rush-hour fast services, and the return is € 5.10. There is no ticketed sight you need. You walk the old centre, the marina and out to the Boca do Inferno cliffs, then sit on a beach or have lunch. Three to four hours covers it. In winter the beaches lose their point and it becomes a two-hour stroll. Leave after breakfast and you are back in Lisbon mid-afternoon, with time to stop at Belém, which is on the same line.

What to see and do in Cascais

01
Old centre and town beaches
Pedestrian lanes with wave-pattern paving and three small beaches, Conceição, Rainha and Ribeira, all within 10 minutes of the station. An hour is enough to walk it.
02
Boca do Inferno
A collapsed sea cave in the cliffs where the swell crashes through an arch. It is a flat 25-minute walk west of the marina, and free. Best with a rough sea.
03
Seafront walk to Estoril
A level promenade of about 3 km that runs east past small beaches and tidal pools. It takes 40 minutes one way, and you can board the train back at Estoril.
04
Museum quarter
A cluster of small museums around Marechal Carmona park, including the Santa Marta lighthouse and the Paula Rego gallery. Most are shut on Mondays. Pick one and allow 45 minutes.

How to spend the day

Take a train from Cais do Sodré around 09:40 and arrive by 10:20. Walk through the old centre to the marina and on along the coast road to Boca do Inferno, then back the same way. Lunch near the beach at 13:00. Catch a train back around 14:30; they leave every 20 minutes off-peak. Get off at Belém on the way if you still have energy.

Cascais in summer and in winter

Summer

June to August

This is beach season, and the reason to stretch the visit to five hours. The town beaches are small and full by 11:00 at weekends, and the trains from Cais do Sodré are standing room on Saturday and Sunday mornings. The Atlantic stays cool, around 18-19 °C, even in August. An afternoon breeze often picks up.

Winter

December to February

With highs around 15 °C and rain on a third of days, the beaches lose their point and the visit shrinks to a two-hour walk. Boca do Inferno is at its best now, when winter swell hits the cliffs. Go on a clear day, eat lunch, and combine it with Belém on the way back.

How crowded it gets

Busy

Busiest: Jul-Aug weekends, 11:00-17:00
Quietest: Weekdays Oct-May; mornings before 10:30

Go on a weekday and take a train before 09:30 in summer. If the town beaches are full, walk 15 minutes along the promenade towards Estoril, where there is more sand and fewer people.

How do you get to Cascais from Lisbon?

Train

Travel time: 40 min
Frequency: Every 20 min off-peak, more at rush hour
Cost: € 5.10 return
Departs from: Cais do Sodré station

CP Cascais line to the last stop, with the river and the sea on the left side going out. Buy the Lisbon-Cascais return for € 5.10 at the machines; it loads onto a Navegante card (€ 0.50). The beaches and the old centre are a short walk from the station.

Organized tour

Travel time: 8 hours, about 1.5 hours in Cascais
Frequency: Daily
Cost: From € 79
Departs from: Hard Rock Café, Restauradores square

Only worth it if you want Sintra on the same day. The combined coach tour spends the morning at Pena Palace and gives you about 1.5 hours of free time in Cascais on the way back. For Cascais alone, take the train.

Practical: clothes, food and money

What to wear

Swimwear, a towel, sunscreen and a hat from June to September. Bring a windproof layer in any season, because the coast road to Boca do Inferno is exposed. Trainers are fine.

What to eat

Grilled fish and seafood rice are what the town does, and the restaurants near the beaches and the old fish market cost more than the back streets. For a cheap lunch, buy bread, cheese and fruit and eat on the promenade wall.

What you will spend

On your own€ 5.10

With the tour€ 79

The train return is € 5.10 and nothing else is compulsory: the town, the beaches and Boca do Inferno are free. Lunch is the main cost. Sunbed hire on the beaches and the small museums are optional extras.

How to get the most out of the day

Sit on the left side of the train leaving Cais do Sodré. The line follows the river and then the open coast all the way.
To stop at Belém on the way back, check that your train calls there, since fast ones skip it, and expect to pay a separate fare.
Guincho beach, 8 km further on, is for surfers and walkers. It is windy and the currents are strong, so do not plan a swim there.
