Portugal’s most beautiful sea cave, Benagil Cave
The coastline of southern Portugal is full of the most beautiful natural caves, sea stacks and secluded beaches. It’s a nature wonderland, as the Atlantic ocean waves have carved out intricate cave formations that are breathtaking.
While some caves are completely dark and submerged under water, some are extremely small and narrow. However, the Benagil Sea Cave is the most spectacular and attracts visitors from all over the world.
The Benagil Sea Cave is located east of the town of Benagil, Algarve. The cave is airy and well-ventilated, since there are two holes that make up a window to the sea. A huge circle on the cave’s roof provides ample sunlight, which creates an ethereal spectacle of colors and nature. This makes the cave a natural haven for photographers and tourists. There’s also an “indoor beach” within the cave, that would provide a secluded retreat for visitors.
From Algave, a boat tour can be arranged to visit Benagil. Aim to visit just before dawn or sunset, in order to catch a breathtaking twilight.

- Coordinates
- 37.087203, -8.4237179
- Access
- Reach the cave from the sea under Portimão Captaincy rules. Entry by swimming or flotation aid, landing or using the sand inside, and unguided non-motorized rentals in the regulated area are prohibited. Use an operator-led boat or guided paddle trip, wear the required life jacket and follow current maritime notices; trips can be cancelled for sea conditions.
- Admission
- There is no separate cave admission ticket. One operator example: Benagil Express lists its two-hour Benagil & Marinha boat tour from Portimão from €35 for ages 11+, €20 for ages 3–10 and free for ages 0–2. It lists a private trip from €517.74. Prices and routes can change; confirm the chosen departure with the operator before booking.
- Time needed
- The maritime rule limits time inside the cave to 2 minutes for powered craft and up to 8 minutes for a guided non-motorized group. These are in-cave limits, not the full outing. Benagil Express lists a 2-hour coastal tour from Portimão; other routes differ.
- Best season
- No official best season is specified. A current visitor guide says tours are offered year-round, but access depends on sea conditions and operators can cancel; check the forecast and confirm the trip shortly before departure.
- Opening hours
- No fixed public opening hours or ticket gate. Visits are scheduled by operators and depend on sea conditions and current maritime notices. Navigation in the regulated area is prohibited from sunset to sunrise. Confirm the departure and cave entry with the operator on the day.
