🗺️ Route Highlights

Nazaré → Eucalyptus Forests

Depart from the legendary surf town of Nazaré and climb inland through dense eucalyptus and pine forests. The gravel roads twist through the hills, with constant scent of resin and ocean air behind you.

Porto de Mós → Serras de Aire

Reach the medieval village of Porto de Mós, dominated by its iconic green-tiled castle, before beginning the main climb into the Serras de Aire. Expect a mix of steady gravel ascents and rocky ridges with panoramic views across the limestone hills.

Serra dos Candeeiros Wind Park

Cross the spine of the Serra dos Candeeiros, passing the impressive Parque Eólico wind turbines. This high plateau offers incredible 360° views — one of the most scenic gravel sections in Portugal.

Caldas da Rainha → Lagoa de Óbidos

Descend through quiet rural roads to Caldas da Rainha, then head toward the shimmering Lagoa de Óbidos. Smooth gravel paths wind between farmland, dunes, and coastal wetlands — perfect for a mid-ride break.

Foz do Arelho → São Martinho do Porto → Nazaré

Follow the Atlantic coastline north through Foz do Arelho and São Martinho do Porto, with the ocean always in view. The final stretch back to Nazaré offers fast-rolling gravel and sea breeze — a powerful finish to an epic day in the saddle.
