What is Marina De Cascais?

Cascais Marina is a working harbor designed around major international sailing events. It has hosted the America's Cup World Series (2011), the ISAF World Sailing Championship (2007), the 49er European Championship, the QuebraMar Regatta, Cowes-Cascais, the Round Portugal Sailing Tour, Portugal Match Cup, and the King Juan Carlos I Trophy, among others. These competitions have drawn sailors and European royalty—including King Juan Carlos I of Spain, Constantine of Greece, and Harold of Norway—who are themselves sailing enthusiasts.

The connection runs deep. King Carlos I, Portugal's last king, chose Cascais as his summer residence and founded one of the world's important oceanographic laboratories here, reflecting his passion for maritime study. Today, the marina blends that nautical heritage with modern facilities.

Located just outside Lisbon, Cascais Bay has a relaxed, cosmopolitan feel despite its proximity to the capital. The bay offers reliable wind direction and moderate breezes—ideal conditions for competitive sailing. Spectators can watch races from numerous vantage points along the shore. The marina accommodates 650 vessels and continues to upgrade its facilities, services, and safety standards. It was the first venue to host the America's Cup World Series in its new format, cementing its reputation as a world-class sailing destination.

It sits alongside certified beaches along Lisbon, part of a broader network of certified beaches throughout Portugal certified annually by the Foundation for Environmental Education.

Bathing Water Quality: Good — verified under EU Bathing Water Directive standards. Blue Flag certification requires annual water quality monitoring.
