Cascais – A Coastal Town Where Heritage, Nature, and Atlantic Lifestyle Meet

Cascais stands on Portugal’s southwestern coast, where the Atlantic meets a landscape of cliffs, sandy bays, noble villas, and maritime tradition. Once a royal summer retreat, today it balances cosmopolitan living with natural beauty, creating one of the most distinctive environments in the Lisbon region. Its identity blends oceanfront geography, Mediterranean climate, cultural heritage, and contemporary leisure in a single, harmonious setting.

Where is Cascais and what defines its character?
