Cascais

Cascais is an Atlantic coastal town 30km west of Lisbon that packs sandy beaches, a compact historic center, excellent seafood, and easy access to Sintra’s palaces into one of Portugal’s most attractive short-break destinations. Once a fishing village that became a royal summer retreat in the late 19th century, it now balances boutique hotels and surf schools with traditional tiled facades and family-run pastelarias. The climate is mild year-round: summers average 26°C (79°F) with virtually no rain, winters hover around 15°C (59°F) with bursts of Atlantic rain between long sunny spells.

Welcome to Cascais

Stretching along the Estoril Coast where the Tagus River estuary meets the Atlantic, Cascais occupies a privileged geographical position. The Serra de Sintra hills shelter the town from northern winds while the open Atlantic moderates temperatures year-round. The coastline shifts dramatically as you move west: sheltered sandy coves in the center give way to the wild, windswept expanses of Guincho and the rocky cliffs of Cabo da Roca, continental Europe’s westernmost point. The town itself is compact and walkable, with cobbled lanes, seafood restaurants, and a marina filled with sailing boats, all within a 15-minute walking radius of the train station.
