Discover the stunning Benagil Cave on this 4-hour boat tour along Portugal’s Algarve coastline, with opportunities for swimming and dolphin spotting.
Imagine gliding along Portugal’s breathtaking Algarve coast, surrounded by rugged cliffs, shimmering waters, and the promise of discovering one of the world’s most iconic caves. That’s exactly what this Benagil cave tour offers—a half-day adventure full of scenic views, memorable moments, and a touch of ocean magic. With a solid 5.0 rating from travelers, it’s clear this trip hits the right notes for most visitors.
What makes this tour stand out? For us, it’s the chance to see the famous Benagil Cave from a comfortable boat, with plenty of opportunities to swim in crystal-clear waters, and perhaps even spot some playful dolphins. One of the biggest perks is the scenic route along the coast, passing by stunning beaches like Falésia, which are worth the trip alone.
However, a key consideration is the ocean conditions—while the boat crew does their best, sometimes waves or swell can prevent getting too close to the cave’s interior. For some, this might be a slight disappointment, but it doesn’t detract from the overall beauty of the experience.
This tour suits those who love nature, photography, and a relaxed ocean excursion. It’s accessible for most travelers and offers a good blend of sightseeing, swimming, and a laid-back vibe. If you’re after a memorable, authentic Algarve adventure at a reasonable price, this trip could be a great choice.


Starting from Viamoura Marina at 10:00 am, the tour lasts about four hours, giving you plenty of time to relax and soak in the sights. The boat used is a motor catamaran (either Puma or Lince), chosen for stability and ample space—ideal for a group of up to 15 travelers.

The journey begins at the Viamoura Marina, a convenient meeting point easily accessible by public transport or car. Once onboard, you’ll immediately feel the relaxed vibe as the crew explains what’s ahead. The departure time, early in the day, is perfect for avoiding the crowds and catching the best light for photos.
As you leave the marina, the boat glides past some of the Algarve’s most renowned beaches, including Falésia, famed for its dramatic cliffs and golden sands. The scenery alone makes this ride worthwhile, with high cliffs rising sharply from the water and secret coves tucked away along the coast.
The main event is reaching the Benagil Cave, often called the “cathedral” of caves. The boat approaches carefully, and if ocean conditions permit, you’ll get to enter the cave—a truly awe-inspiring sight with its massive, arching opening and stunning interior. The crew explains the cave’s geology and history, enriching the visual experience.
One reviewer, Galina, noted that the crew “explained every area and brought everyone’s mood high,” highlighting the importance of engaging guides. Be prepared for some photo opportunities—many guests find themselves snapping dozens of pictures against the cave’s dramatic backdrop.
If the tide or swell doesn’t allow entry into the cave, don’t worry. There are plenty of other smaller caves and beaches along the coast to explore. The boat often stops for a swim in the crystal-clear waters—an activity praised by nearly all reviewers. Jessica loved being able to “swim right in front of the cave,” which was a highlight for her.
While not guaranteed, the chance to spot dolphins is a nice bonus. Several travelers mentioned seeing these intelligent creatures during their trip, adding to the magic of the day. The crew’s knowledge and attentiveness seem to improve the likelihood of a dolphin encounter, making the experience even more memorable.
After roughly four hours on the water, the boat returns to Viamoura Marina. Guests often leave with plenty of photos, happy memories, and sometimes a little sun-kissed glow from the deck.

The tour price of $59.29 per person offers good value considering the scenic beauty, guided commentary, and the chance to swim and possibly see dolphins. Included in this price is a free drink—either white wine, juice, or water—to sip while enjoying the views.
Meals are not included, so it’s a good idea to bring snacks or plan to eat before or after. The boat is equipped for comfort, but bring sunglasses, sunblock, and a towel if you plan on swimming.
Reviewers consistently mention the friendly, knowledgeable crew. One even praised the captain for trying to get closer to the cave despite ocean swell challenges, showing the dedication to customer experience. The boat’s comfort and the relaxed atmosphere seem to be appreciated by most, especially for those who dislike cramped or noisy tours.
The small group size (max 15 travelers) allows for a more intimate and personalized experience, making it easier to ask questions or take photos without feeling rushed.

While some might expect a luxury vessel or sailboat, the tour uses a motor catamaran, which provides stability and space at a reasonable price. The 4-hour duration strikes a good balance—enough time for multiple stops, swimming, and coast viewing without feeling overly long or rushed.
The price point of just under $60 makes this a budget-friendly option for many, especially given the stunning scenery and the chance to see one of the world’s most photographed caves.

This experience is ideal for first-time visitors to Algarve wanting a scenic, laid-back boat trip with plenty of photo ops. It suits families, couples, or solo travelers seeking a relaxed, authentic adventure with opportunities for swimming and dolphin sightings.
Travelers who prefer a small group environment will enjoy the cozy, less commercial atmosphere. It’s also perfect for those who want to avoid the crowds but still experience the beauty of the coast and the cave.

The Benagil Cave Tour offers an engaging, scenic, and affordable way to explore Portugal’s Algarve coastline. While ocean conditions can sometimes limit cave entry, the boat trip still delivers spectacular views, opportunities to swim, and dolphin sightings that elevate the experience. The friendly crew, combined with the small group size, makes it a relaxed and personal adventure for most travelers.
