Along Portugal's Atlantic coast, this protected area spans limestone cliffs, sandy beaches, and pine forests where rare species like the Bonelli's eagle nest.
Sintra-Cascais Natural Park covers 145 square kilometers along Portugal's western coast. When you visit, you might walk along the 100-meter cliffs at Cabo da Roca, swim at Praia Grande beach, or explore the Serra de Sintra mountains. The park includes unexpected discoveries: dinosaur footprints from the Jurassic period embedded in coastal rocks, small villages producing Colares wine behind stone walls, and a unique microclimate where rare plants thrive next to 16th-century monasteries.
You can reach the park from Lisbon in about 40 minutes. Take a regular train to Sintra town, then catch bus 403 to access Cabo da Roca and the coastal areas. Visit during spring (March-May) or autumn (September-November) when temperatures stay between 15-20°C and you'll encounter fewer tourists than in summer.
Walk along the Atlantic edge to reach Cabo da Roca, mainland Europe's westernmost point, where cliffs drop 100 meters to the sea. At Cabo Raso near Cascais, waves have created intricate patterns in the limestone cliffs. In Azenhas do Mar, white buildings cascade down the cliff face toward a small beach and natural pool.
The coastline includes several distinct beaches. Strong winds at Guincho Beach create ideal conditions for windsurfing and surfing. At Praia Grande, walk to the southern cliff to see 11 sets of dinosaur tracks preserved in the rock. Praia da Adraga sits between two tall rock formations, while Praia das Maçãs leads to protected sand dunes you can explore on marked paths.
The Serra de Sintra mountains create their own weather system. Atlantic moisture supports thick growths of moss, ferns, and oak trees. You can follow walking paths through the mountains to reach the stone-built Convent of the Capuchos and climb to the Hermitage of Peninha. On the northern slopes, you'll pass through villages where granite walls protect fields from strong maritime winds.
Since 1995, UNESCO has recognized Sintra's integration of architecture and nature. The 10th-century Castle of the Moors sits on a hilltop with views across the entire park. At Monserrate Palace, you can walk through gardens filled with plants from five continents, while the building itself reflects Gothic, Indian, and Moorish designs.
In the park's northern section, walk between granite walls marking ancient field boundaries. These walls protect Colares wine grapes from ocean winds. Despite being just 25 kilometers from Lisbon, farmers here maintain traditional agricultural methods, growing grapes and vegetables in the mineral-rich soil.
