Taking a boat ride along Portugal’s Algarve coast is one of those experiences you’ll never forget, especially when it involves visiting the world-famous Benagil Cave and swimming in the shimmering waters of Marinha Beach. While I haven’t personally been on this exact tour, a detailed look at what travelers have shared paints a clear picture of what to expect.
What makes this journey truly appealing are the stunning coastal scenery, the small-group intimacy, and the knowledgeable guides who make every stop insightful and fun. On the flip side, since the tour depends heavily on weather conditions, there’s a small chance it might be canceled, but the company’s flexible refund policy helps keep things stress-free.
If you’re someone who loves scenic, quick, and engaging excursions that combine breathtaking views with chances to relax and swim, this tour seems perfect. It’s especially suited for travelers who want a taste of Algarve’s best spots without the hassle of long transfers or crowded boats.

Starting Point and Safety Briefing
Your adventure begins at Swell Tours in Portimão, where you’ll meet your guide, who will be wearing a recognizable blue t-shirt. It’s advisable to arrive about 15 minutes early so you can settle in and listen to the brief safety instructions. The tour is designed to be both fun and safe, with life jackets provided and a knowledgeable crew ensuring everyone is comfortable.
Scenic Coastal Viewpoint and Guided Tour
The first part of your journey offers a guided sightseeing experience lasting about 1.5 hours. As your speedboat glides over the waves, you’ll get spectacular views of Algarve’s rugged cliffs, hidden coves, and pristine beaches. The guides, who speak Portuguese, English, and Spanish, are praised for their friendliness and enthusiasm, often sharing fascinating details about the coastline and its geological formations.
One reviewer, Inês from Switzerland, mentions, “The boat trip is beautiful, and the guides are simply top, so friendly.” This suggests you’re in good hands, and the crew’s local knowledge really enhances the experience.
Secret Swimming Stop
Midway through, there’s a special secret stop for about 10 minutes where you can jump into the clear, inviting waters. This is a highlight for many, especially those who enjoy a quick swim in the ocean. The reviews consistently mention the pleasure of swimming in the “pristine” waters, with one guest noting they didn’t want to leave the boat at Benagil because of the fun atmosphere and scenic setting.
More Great Thing To Do NearbyVisiting the Famous Caves and Beaches
The Benagil Cave is undoubtedly the star attraction. Known for its natural dome and hidden beach inside, it’s one of the most photographed spots along the coast. The tour guides are praised for their explanations and for sailing into the caves, giving you a real sense of their scale and beauty. As Maríadel MarViedma from Spain puts it, “Andrea, the guide, and Pedro, the driver, were charming, showing us all the caves and explaining every detail.”
Next, your boat will head toward the Marinha Beach, often hailed as one of Portugal’s most stunning beaches. You’ll have the chance to swim in its famous blue waters, enjoy the peaceful surroundings, and take in the incredible cliff formations that frame the beach. Several reviews highlight the spectacular scenery and the refreshing stop at Marinha as a key highlight.
The Return Journey
After soaking in the views and enjoying some leisure time, the boat heads back to Portimão, typically after a total of around 2 hours. The return trip offers one last chance to relax, take photos, or simply enjoy the sea breeze.
What Makes This Tour Stand Out

Small Group Setting and Personal Touches
With a maximum group size, you’ll find this tour offers a more intimate experience. Guests consistently mention the friendly and attentive guides, like Andrea and Pedro, who go the extra mile with explanations and friendly service. As one reviewer from Germany put it, “All felt very safe, and the guides were always communicative.”
Authentic and Uncrowded Experience
Unlike larger tours that can feel rushed or crowded, this experience emphasizes quality over quantity. The small group ensures more time at each stop, more personalized interaction, and better chances for photos and swimming.
Value for Money
At around $33 per person, this tour provides incredible value. For just two hours, you get to see some of Algarve’s most iconic natural sights and enjoy time swimming in the sea. The inclusion of a live guide, life jackets, and the small-group format make it a practical choice without sacrificing quality.
Focus on Safety and Comfort
Prioritizing safety, the tour is compliant with Portugal’s “Clean and Safe” standards, providing peace of mind. Plus, the trip is suitable for most ages, though it’s not recommended for pregnant women, those with back problems, or mobility issues.
