Cascais Travel Guide - Beaches, Getting There & What to Do

Cascais is a coastal town 30km west of Lisbon, at the western end of the Estoril coast train line. It was a royal fishing village until the late 19th century, when the Portuguese royal family began spending summers here and European aristocracy followed. That history left behind a town with more architectural substance than most beach resorts - a walled old town, a working fish market, a marina, and several good museums - alongside the beaches that bring most visitors today.

The town has a permanent expat population and is noticeably more international than most Portuguese towns of similar size. It also functions as a commuter town for Lisbon professionals, which keeps local services - supermarkets, pharmacies, good restaurants - running year-round rather than shutting in October.

Getting There

The Linha de Cascais train from Cais do Sodré station in Lisbon takes 40 minutes and costs €2.35. The line runs from 5:30am until just past midnight, with trains every 20–30 minutes. The journey passes through Belém (stop: Belém), Estoril (stop: Estoril), and arrives at Cascais station, which is a 5-minute walk from the marina and beaches.

By car from Lisbon: take the A5 motorway, 30–40 minutes depending on traffic. Parking in the centre is metered but available. A more scenic drive goes along the Marginal coastal road - longer but the views over the estuary and coast are worth it.

The Town Centre

Cascais centre is compact and walkable. The Mercado de Peixe (fish market) near the marina is active in the mornings and worth seeing - tuna, swordfish, sea bass, and the day’s catch from local boats. The marina itself has a range of restaurants, with the terrace spots on the eastern side offering better views than the chain outlets closest to the water.

Rua Frederico Arouca is the pedestrianised main shopping street, lined with local shops and a few tourist-facing places. The Museu do Mar (museum of the sea) and Museu dos Condes de Castro Guimarães (a 19th-century estate with eclectic art collection, free Sundays) are the best indoor options in town.

Beaches

Praia de Cascais is the main town beach, directly below the old town. It’s a short sandy arc, busy in summer, and within easy walking distance of the train station. The water is cooler than the Algarve (16–20°C) but perfectly swimmable May through September.

Praia da Rainha is adjacent, smaller, and slightly calmer. Both beaches face the bay rather than the open Atlantic, which moderates the wave conditions.

Praia do Guincho is 8km north of Cascais, accessible by bus (Scotturb 405) or taxi. It’s a wide Atlantic-facing beach backed by dunes, with near-constant wind that makes it one of the top surf and kitesurfing spots in Europe. Water temperatures are cold and currents can be strong. The restaurant at the dunes (Restaurante do Guincho) serves reliable grilled fish. The setting is dramatic on most days and spectacular in autumn storms. See our full Guincho surf guide for wave conditions, kite and windsurf details, and what to expect by season.

Boca do Inferno

A 20-minute walk west along the coastal promenade from the town centre brings you to Boca do Inferno - a natural arch and sea cave carved into the cliffs. The name is theatrical (it translates as “Mouth of Hell”), and the formation is most impressive in rough weather when waves funnel through the rock. Calmer days are still worth visiting for the cliff scenery. Entry is free. There are a few stalls selling craft items nearby.

Sintra–Cascais Natural Park

The natural park stretches north from Cascais into the Serra de Sintra. It encompasses Guincho beach, the Cabo da Roca (the westernmost point of continental Europe, 16km north of Cascais), and extensive coastal scrubland. Bus 403 from Cascais runs to Sintra via Cabo da Roca, making it possible to combine Cascais and Sintra in a single day without returning to Lisbon.

Where to Eat

The fish and seafood around the marina are generally good. O Pescador on Rua das Flores 10 is a reliable choice for traditional grilled fish. Taberna da Praça near the market has a short menu of Portuguese standards and decent wine. The market stalls and nearby cafés offer simpler lunches at lower prices than the marina terraces.

Best Time to Visit

May, June, September, and October are the most comfortable months - warm enough for beach use (20–25°C), with shorter queues and lower prices than July and August. Cascais gets very busy in summer but manages crowds better than Sintra. The town stays active year-round, making it a viable visit even in winter for the coastal scenery.

How Cascais Compares

Cascais vs Sintra: Both are on the same Lisbon train line but feel entirely different. Sintra is about palaces, forested hillsides, and a slightly overwhelming popularity in high season — a full day minimum, best done early. Cascais is a coastal town: seafront promenade, beaches, restaurants, afternoon wine. Cascais suits those who want relaxation over sightseeing. Many visitors do both in a single day by taking the coastal road between them — Sintra in the morning, Cascais for lunch and the afternoon. Cascais wins on practical comfort; Sintra wins on spectacle. See our Sintra vs Cascais comparison for the full breakdown.

Cascais vs Setúbal: Setúbal (south of Lisbon, 50 minutes by bus) offers a similar coastal appeal — fishing town character, proximity to the Arrábida Natural Park, cleaner beaches — but without the tourist infrastructure of Cascais. Cascais is more polished, more expensive, and better connected; Setúbal feels more local. For travellers who want the Lisbon coast without the Estoril-line crowds, Setúbal and the Arrábida beaches are worth considering as an alternative base. Both are viable day trips from central Lisbon.

Cascais in Context

Cascais is the western anchor of the Lisbon Riviera - Sintra is 20km north via the EN247 cliff road, and Lisbon is 30km east by train. The surf beach at Praia do Guincho sits between them - 8km north of Cascais. For surf trips further north, Ericeira is 40km and Peniche is 80km - both reachable by car along the coast road.
