Starting Point and Comfort of the Trip

The adventure begins at Lagos Marina, with easy parking and a straightforward meeting point next to pier D. The guide, dressed in a recognizable blue Atlantic Breeze hat and white T-shirt, immediately sets a friendly tone. The boat itself is a sturdy fiberglass vessel, designed for stability, with a bathroom onboard—an often overlooked detail that makes all the difference on a two-hour trip. The ample space around the boat allows for plenty of photo opportunities and comfortable viewing, so you’re never squished or forced to lean over the edge.

The Scenic Route from Lagos to the Caves

As the boat departs, you’ll glide past some of the Algarve’s well-known beaches like Praia da Rocha and Alvor beach. These beaches are famous for their long stretches of golden sand and vibrant surf, but it’s the journey along the cliffs that truly captivates. The cliffs are steep, rugged, and filled with stories—pirates, smugglers, and hidden treasures—many of which your local guide will happily recount.

The approximately two-hour trip is well-paced, giving you a chance to take in the scenery, snap photos, and settle into the relaxed pace of a boat trip. The size of the group is generally moderate, making it an intimate experience without feeling crowded, which enhances the overall atmosphere.

The Highlight: Benagil Cave

The star of this trip is without doubt Benagil Cave. Recognized by The Guardian as one of the world’s top 10 wonders, this iconic sea cave features a massive, circular opening that floods the interior with natural light. The guide will narrate the cave’s history, including its formation and the legends that surround it. Many reviews highlight how breathtaking and surreal the interior feels, especially when sunlight filters through the opening, illuminating the sandy floor.

You’ll have time to admire the cave from the boat, take photos, and soak in the scenery. The water here is calm enough for a swim, which is included in the tour. The swimming stop is often a favorite moment, giving travelers a chance to cool off and enjoy the transparent waters of the Atlantic. Reviewers frequently mention how refreshing and invigorating the swim was, and some even appreciated being able to snorkel if they brought their gear.

Exploring Secret Caves and Beaches

Beyond Benagil, your guide will navigate the boat into lesser-known caves and small beaches only accessible by water. These hidden spots are part of the appeal, as they come with stories of pirates and smugglers, adding a layer of intrigue. Since these caves are only visible from the water, they offer a secluded, almost private feel—perfect for those craving a bit of adventure off the beaten path.

Return Journey and Final Impressions

After the swim and exploration, you’ll head back along the coast, passing more scenic spots. The return to Lagos Marina provides ample time to review photos, discuss the highlights, and relax after an immersive experience.

What’s Included and What to Bring

The tour includes a life jacket, a local guide who is knowledgeable and engaging, and fuel—so you don’t have to worry about the technicalities. However, you’ll need to bring your own food and drinks, a beach towel, sunscreen (preferably biodegradable), and a hat to shield yourself from the sun. It’s wise to carry a charged smartphone for photos and videos, especially since the scenery is so photogenic.

Remember, littering is not allowed, so keep your trash small and dispose of it properly after the trip.
