Benagil Cave & Marinha Beach – 2h Boat Tour from Portimão
Discover the sea caves, golden arches, and hidden shores of Portugal's most iconic coastline.
This Benagil Cave boat tour takes you along one of Europe's most celebrated stretches of Atlantic coastline, letting you look directly inside the cathedral-like sea cave that has made the Algarve famous worldwide. The route combines dramatic rock architecture with sheltered coves and opportunities to swim in clear, calm waters.
Departing from the historic Cais Vasco da Gama on the Rio Arade in Portimão, the boat heads west along a shoreline shaped by centuries of wave action into arches, tunnels, and golden limestone stacks. Early stops include Praia da Rocha and Praia dos Caneiros before the route curves toward the distinctive formations of Algar Seco near Carvoeiro.
Beyond the Alfanzina Lighthouse the coast grows wilder, and small beaches such as Praia do Carvalho appear tucked beneath towering cliffs. The tour culminates at Benagil, where the boat enters the famous sea cave and guests can appreciate its domed ceiling and interior beach from the water.
The experience is rated easy and suits a wide range of guests. The two-hour duration keeps the itinerary focused without feeling rushed, and the calm inshore waters make this a comfortable outing even for those who are not experienced sailors.

Cruise past Algar Seco, a protected coastal park of sculpted rock pools and natural arches near Carvoeiro.
Pass the historic Alfanzina Lighthouse, a landmark visible for miles along this stretch of the Algarve.
Stop for a swim at a hidden beach along the route and cool off in the Atlantic.

Itinerary
The tour begins at the pier on the Rio Arade in Portimão. The boat moves out through the river mouth and turns west toward the open Atlantic coast.
The boat passes the broad sandy beach of Praia da Rocha and then rounds the headland toward Ferragudo to view the quieter Praia dos Caneiros and its surrounding rock faces.
The coastline near Carvoeiro features Algar Seco, a protected park of eroded limestone formations, sea grottos, and rock pools. Praia do Vale de Centianes is a sheltered beach framed by high cliffs visible from the water.
Passing the white-and-red Alfanzina Lighthouse, the route continues to Praia do Carvalho, a tucked-away beach reachable from land only through a cliff tunnel, making the boat perspective particularly rewarding.
The boat enters the famous Benagil Cave, known locally as Algar de Benagil, and pauses so guests can take in the domed ceiling, natural skylight, and interior sand beach. This is the centrepiece of the tour.
