SintraCascais

Sintra-Cascais refers to the region around the municipalities of Sintra and Cascais in the Lisbon District, Portugal, on the Atlantic coast known as the Portuguese Riviera. It is notable for its landscapes, historic towns, and cultural heritage.

The region includes the Serra de Sintra, a wooded hill range with palaces and estates, and a rugged Atlantic coastline with beaches such as Guincho and Azenhas do Mar. The westernmost point of continental Europe, Cabo da Roca, lies nearby. The area includes the Sintra-Cascais Natural Park, established to protect natural and scenic values.

The historic center of Sintra is a UNESCO World Heritage Site since 1995, recognized for its 18th- and 19th-century romantic palaces and estates. Notable landmarks in Sintra include Pena Palace, Moorish Castle, and Quinta da Regaleira. Cascais developed as a fishing village and later a royal retreat, featuring a fortified old town, marina, and seaside promenades.

The region is connected to Lisbon by the Sintra Line commuter railway, linking to the urban network. Tourism is a major driver, supported by hotels, restaurants, and protected landscapes. Conservation and sustainable tourism are priorities within the natural park.
