Cascais and Estoril are neighbouring seaside towns on the Estoril coast, about 32 km west of Lisbon. The Comboios de Portugal Cascais line leaves from Cais do Sodre station every 20 minutes or so and takes about 40 minutes, following the Tagus estuary and then the Atlantic shore; Estoril is the stop before Cascais. Driving along the Marginal coastal road is scenic, though summer weekend traffic and parking in Cascais can be slow, so the train is the usual choice.
Estoril is known for its seafront promenade, its palm-lined gardens and the Casino Estoril, one of the largest casinos in Europe. A seaside walkway of around 2 km links Estoril to Cascais past small beaches such as Tamariz. Cascais itself has a former fishing harbour, a pedestrian old town with pastel buildings and shops, the Citadel, and the Museu Condes de Castro Guimaraes. West of town, the sea cliffs at Boca do Inferno, a chasm where waves crash into a rock arch, can be reached on foot or by bike. Further along the coast, Guincho beach is an exposed Atlantic beach popular with surfers and windsurfers, with strong winds and cooler water.
A straightforward one-day arc is to take a morning train to Estoril, walk through the gardens to the sea, and follow the coastal path to Cascais, which takes about 45 minutes. Late morning suits the old town and harbour. Lunch fits in Cascais, where grilled fish, seafood rice and fresh fish at the market area are typical. The afternoon can include Boca do Inferno, a bike ride towards Guincho, or time on a beach, with a train back to Lisbon in the evening.
Summer is the busiest and warmest season, with beach conditions at their best from June to September, though weekends are crowded. Spring and autumn give mild weather and quieter promenades. Winter has stormy seas and fewer open beach cafes, but the walks are pleasant on clear days.
