Cascais is the easy beach escape from Lisbon: a former royal seaside resort with a marina, sandy coves and a dramatic sea chasm nearby, all reached on one of the most scenic short train rides in Portugal. There's rarely any need to overthink how to get there — the coastal line does the job well on its own.

The best way: the coastal train from Cais do Sodré

The Linha de Cascais, a commuter rail line run by CP, departs from Cais do Sodré station in central Lisbon and runs along the Tagus estuary and Atlantic coast to Cascais, taking around 35–40 minutes. Trains are frequent, generally every 15–20 minutes for most of the day, so there's no need to plan around a timetable — just head to the station and catch the next departure. The route itself is part of the appeal: it hugs the waterfront the whole way, passing through Belém, Oeiras and the elegant seafront resort of Estoril before reaching Cascais. If you're arriving from the airport rather than a central hotel, see our Lisbon airport to the city guide first for getting into town.

Driving to Cascais

Cascais is about 30 km from central Lisbon, roughly a 30–40 minute drive via the A5 motorway, which runs a more inland route than the train. Driving suits visitors who want to explore further along the coast at their own pace, such as continuing to Guincho beach or looping back via Sintra, but the A5 carries a toll and traffic can build during rush hour and summer weekends. Parking in central Cascais is manageable outside peak season but tighter in high summer. See our guide to driving in Portugal for tolls and the electronic Via Verde system.

Combining Cascais with Boca do Inferno

Boca do Inferno ("Mouth of Hell"), a rocky chasm where the Atlantic surges dramatically against the cliffs, sits around 2 km from central Cascais along the coast towards Guincho. It's an easy addition to a Cascais day trip: a flat coastal walk of about 25–30 minutes, a short taxi ride, or a stop on some local bus routes running along the same stretch of coastline. The site is free to visit and best seen when the sea is a little rough, though it's worth taking care on the viewing platforms in windy weather.

The coastal path towards Estoril

A paved promenade runs along the seafront between Cascais and neighbouring Estoril, a pleasant walk or cycle of around 3 km that many visitors use to combine both towns in a single day, since both are served by the same train line and stops are only a few minutes apart.

Cabo da Roca

The westernmost point of mainland Europe, marked by a lighthouse and a stone monument above dramatic sea cliffs, lies a further drive or bus ride beyond Cascais and Sintra. It isn't within easy walking or cycling distance of Cascais itself, but a local bus service connects Cascais with Cabo da Roca and on to Sintra, making it possible to combine all three in one longer day if you're not short on time. Our Lisbon to Sintra guide covers the palace town in more detail if you want to plan a fuller loop.

What to see in Cascais

Cascais's old town centres on a small marina and a scattering of beaches within walking distance of the station, making it easy to combine sightseeing with an afternoon by the sea. The Cidadela de Cascais, a former royal fortress, and the small Museu do Mar covering the town's fishing and royal history give a bit of structure to a visit beyond simply relaxing on the sand. Cascais also makes a useful base for exploring further along the Estoril Coast. See our Portugal by train guide for how CP's wider network and tickets work if you're travelling on elsewhere in the country.

Estoril and Guincho beach

The stop before Cascais on the same train line, Estoril, is worth a brief detour in its own right: a grand seafront casino, said to have inspired the setting of Ian Fleming's Casino Royale during his time in Portugal, sits opposite palm-lined gardens a short walk from the station. Further along the coast beyond Cascais, past Boca do Inferno, Guincho beach is a wide, wind-exposed stretch of Atlantic sand popular with surfers and windsurfers, reachable by local bus or taxi from central Cascais in around 15–20 minutes — worth the extra trip for anyone keen on watersports or simply a wilder, less sheltered beach than those closer to town.

Which should you choose?

The coastal train from Cais do Sodré is the clear best option for almost everyone: fast, frequent, scenic and needing no advance booking. Driving only really adds value if you plan to continue further along the coast or combine Cascais with a wider loop that includes Sintra in the same day.
