View of Cascais

Highlight • Viewpoint

The View: A Living Postcard
The bay offers an iconic mix of a traditional fishing village and the aristocratic "Portuguese Riviera." You will see colorful fishing boats anchored in calm blue waters, framed by the historic Citadel and elegant palaces rising from the rocks.

Best Spots to See It:
Hotel Baía Rooftop: The most famous spot for a panoramic, aerial view of the entire bay and town.

Praia da Ribeira (Main Square): The best ground-level view to get close to the fishing boats and the beach.

The Citadel & Marina: Offers a beautiful "reverse" view, looking back at the town, which is stunning at sunset.

Insider Tip: Walk just past the bay to the Santa Marta Lighthouse. The view of the lighthouse and the bridge over the water is arguably the most photogenic spot in Cascais.

A bit away from the Boca do Inferno is this beautiful stretch of coastline. Who likes it nice and quiet should take a little break.

Cresmina Dune

Highlight • Natural Monument

The Cresmina dunes are part of the Guincho-Cresmina dune system, located in the Sintra-Cascais Natural Park in Portugal. This dune system extends over 66 hectares and is considered unique due to the prevailing northwest winds, which cause the sand from the beaches of Guincho and Cresmina to return to the sea approximately 5 km to the south, near Guia, after migrating over a flat, rocky and largely uninhabited area of Cabo Raso.

Nice route, but you should start early. Traffic is still bearable in the morning.
