Experience the Algarve coastline on a 2.5-hour catamaran cruise from Lagos, exploring caves, enjoying scenic views, and swimming in Atlantic waters.
If you’re heading to Lagos, Portugal, and dreaming of those postcard-perfect caves and rugged coastlines, this Benagil caves cruise might be on your radar. It’s a popular choice for visitors wanting to see the famous Benagil Cave and discover parts of the Algarve that land-based tours often miss. The boat ride lasts around two and a half hours, offering a taste of the region’s striking scenery, some swimming opportunities, and hopefully, dolphin sightings.
What we love about this experience is its combination of scenic cruising and accessible adventure — a relaxed way to soak up the coastline without the hassle of land-based crowds. The elevated viewing platform on the catamaran is a real highlight, giving you unobstructed shots of the caves and coast. However, one thing to keep in mind is that the boat’s size and route mean you might not get close to every cave or have time for long exploration inside the formations.
This tour suits first-time visitors to Lagos, families, and those looking for a straightforward, scenic excursion. It isn’t designed for romantic picnics on beaches or long cave visits, but it’s perfect for a quick, memorable day on the water with plenty of photo ops and a good dose of Atlantic breeze.

The tour departs from Lagos, starting at the Days of Adventure meeting point in Passeio dos Descobrimentos. From here, you’ll cruise along the coast, with the crew pointing out beaches, towns, and caves you pass by — an informative touch that adds context to the scenery. The main highlight, of course, is the Benagil Cave, which you will see up close during the trip.
Why the Benagil Cave? Because it’s arguably the most famous sea cave in Portugal, with its distinctive dome and centrally located beach inside. The boat’s elevated platform allows for incredible photos of this natural wonder, often praised by visitors for its unobstructed views. Some reviews mention that the short stop at the cave is just enough time to snap a few photos, with the boat remaining outside the entrance for safety and legal reasons.
Beyond Benagil, you’ll visit other caves along the coastline, each offering unique shapes and formations, visible only from the water. The guides are generally described as knowledgeable and friendly, providing details about the caves’ geology, history, and local stories. This adds a layer of appreciation to the views, as opposed to just sightseeing with no context.
Swimming stops are typically scheduled after the cave visits. This allows guests to enjoy a quick dip in the Atlantic, a highlight for many. Multiple reviews rave about the opportunity to jump into the ocean, especially on hot days, with crew members helping out and offering safety tips. Just remember: swimming is subject to weather conditions and safety considerations, so don’t expect long beaches or lots of beach time.
The return trip heads back to Lagos, usually with the option to spot dolphins, a recurring highlight in reviews. While sightings aren’t guaranteed, the open waters increase your chances, and the crew often keeps an eye out for them.
The tour price is around $39.48 per person, which is quite reasonable for this kind of scenic boat ride. It includes the boat tour itself, with the high vantage point and swimming opportunities. However, lunch isn’t included, so plan your day accordingly if you want a meal. Many travelers choose to bring snacks or plan to grab a bite in Lagos before or after the trip.
The tour operates with a minimum of 12 participants, so it’s a group experience but not overcrowded — most trips cap at 50 travelers, keeping the atmosphere manageable. You’ll receive a mobile ticket, making booking and check-in straightforward, and confirmation is quick once your booking is secured.
Many reviewers highlight the professionalism and friendliness of the crew, with guides like “helpful and informative,” making the experience more engaging. For example, one reviewer appreciated how the guides provided interesting information about the caves and the region, enhancing the sightseeing.
However, some mention challenges with crowded views or short cave stops. One review suggested that taking turns for photos would improve the experience, especially since many guests rush to the front of the boat to snap pictures. Still, the majority emphasize the stunning scenery and the fun of the boat ride itself.
A notable point is the safety and comfort of the boat — travelers mention that despite some choppier waters at times, the large vessel offers stability and space. The boat’s design, with accessible seating and an elevated viewing platform, makes it suitable for families and those with mobility issues, as found in reviews praising its family-friendly setup.
Sailing fans have several other Lagos options to choose from

This cruise is ideal for first-time visitors to Lagos wanting to see the coastline’s iconic caves without the hassle of land-based excursions. It’s perfect for families, couples, or solo travelers who enjoy scenic boat rides and don’t mind the limited time inside caves. If your priority is capturing photos, the boat’s vantage point is a clear advantage.
However, if you’re looking for a longer, more immersive cave experience or beach time, this might feel a bit quick. Also, travelers concerned about seasickness should note that waters can be choppy, as some reviews mention. Those with mobility issues will appreciate the larger boat’s accessibility.
This Benagil Caves cruise from Lagos offers a well-organized, scenic, and affordable way to appreciate some of Portugal’s most stunning coastal formations.

The knowledgeable guides and opportunities for swimming add to the appeal, making this experience more than just a typical boat ride. While it’s not an in-depth cave exploration, it strikes a balance between sightseeing, comfort, and fun, especially for first-timers and families.
