Experience the Algarve's stunning coast with this 2-hour Portimão to Benagil Cave boat tour, including dolphin spotting and cave exploration.

If you’re dreaming of exploring Portugal’s famous coastlines, this 2-hour boat cruise from Portimão to the Benagil Caves and Marinha Beach offers a practical way to see some of the Algarve’s most iconic sights. While it’s a shorter trip, it packs enough scenic beauty, dolphin sightings, and cave adventures to satisfy most visitors.
One thing we really appreciate about this tour is its affordable price point of just over $46 per person, making it accessible for many travelers seeking a memorable experience without breaking the bank. That said, some guests note that the tour can be crowded and not always as comprehensive as hoped — particularly when it comes to visiting all caves or Marinha Beach.
This cruise suits those who want a quick, scenic, and relaxed outing that combines sightseeing with a chance to cool off in the sea. If you’re after a more in-depth, historical, or uncrowded experience, you might want to explore other options. But for a fun, family-friendly, and scenic boat ride with chances to see dolphins, this tour hits the right notes.

This tour, operated by Manguito, departs from Clube Naval De Portimão and lasts approximately 2 hours. The boat is a comfortable catamaran, designed to navigate easily into caves and along the rugged coastline. Expect a lively, friendly crew that’s eager to share their knowledge about the area’s natural formations and wildlife.
The cruise begins with a gentle sail past Praia Grande, Portugal’s famous sprawling beach, giving guests a chance to snap some stunning photos from the water. As the boat moves along, you’ll pass the Fortress of Santa Catarina, a historical landmark providing a scenic backdrop, and several vantage points ideal for picture-taking.
Of course, the star of this trip is the Benagil Caves, a series of spectacular rock formations carved by the sea. The boat will cruise in front of these caves, giving everyone a chance to admire the natural beauty. While some reviews note that the boat size limits how close you can get or whether you can land inside, most agree that the view from the water is breathtaking.
A key feature of this tour is a stop for swimming at a heavenly beach, offering travelers a refreshing break from the boat ride. This is a chance to relax, splash around, and enjoy the warm waters of the Algarve. Several reviews mention the crew’s friendliness and willingness to assist with swims, which adds to the relaxed vibe.
Plus, there’s a good chance to spot dolphins along the way, with some reviews highlighting dolphin sightings as a highlight. The guides often keep an eye out and share their enthusiasm about spotting these playful creatures, which can be quite the memorable experience.
More ways to experience Portimao from the water include these boat tours
While many guests find the tour enjoyable, a few reviewers mention that not all caves are accessible or included due to boat size and weather conditions. Some also express disappointment that they didn’t get to visit Marinha Beach, despite its mention in the tour name — the boat often turns back after the Benagil Cave, which can be a letdown if you’re hoping to combine multiple spots.
The chaotic check-in process and large group sizes can also impact the experience. One reviewer shared that the check-in was “chaotic,” with some confusion about boarding, and that the boat’s engine fumes could be nauseating, especially during maneuvers in caves.
The tour departs from Clube Naval De Portimão, a straightforward location accessible via public transportation. The maximum number of travelers is 600, so expect a bustling scene during peak times. This large group size means you might be sharing the experience with many others, which can impact intimacy and comfort, especially in tight cave spaces.
The catamaran itself is described as medium-sized, which strikes a balance between being large enough to accommodate many guests and small enough to navigate into caves. However, some reviews mention that the boat can feel cramped, especially when crowded, and that certain caves can’t be fully entered or explored due to restrictions.
Guests consistently praise the friendly, knowledgeable staff, with some reviews mentioning guides who are lively, humorous, and eager to share facts about the coastline. However, a few report that audio explanations are difficult to hear, especially in noisy conditions or if you’re sitting at the back of the boat. An idea for improvement common among reviewers is the use of a microphone system for better communication.
A small perk is the inclusion of iced tea, which many travelers appreciate as a refreshing beverage during the ride. However, some reviewers note that beverages were not served to everyone, and that at times, fumes from the engine can be unpleasant, especially during backup maneuvers in caves.
The tour offers multiple departures daily, making it easy to choose a time that fits your schedule. It’s recommended to book 9 days in advance (on average) to secure your spot. The trip’s duration, at about 2 hours, makes it suitable for most travelers, although some wish it were longer to explore more caves or beaches.

At $46.26 per person, this tour offers a solid balance of affordability and experience quality. The inclusion of dolphin sightings and a swim stop add to its appeal, especially considering the scenery is stunning and the guides are generally enthusiastic.
However, the limited access to some caves and the large group size may not suit travelers seeking an intimate or in-depth exploration. For many, the value lies in the easy, guided experience that provides great photo opportunities and a taste of the Algarve coast’s beauty without the need to rent your own boat or navigate unfamiliar waters.

This experience is ideal for families, first-time visitors, and those short on time who want a quick but visually stunning boat trip. If you’re comfortable with crowds and are mainly interested in the scenic views, dolphin sightings, and experiencing the caves from the water, this trip will satisfy.
However, if you’re after a more secluded, less crowded, or more educational tour, you might want to look into other options. Also, travelers keen on visiting Marinha Beach specifically may find this tour disappointing, as it often doesn’t include the stop.

This cruise from Portimão to the Benagil Caves offers a beautiful, family-friendly way to enjoy the Algarve coastline in a short amount of time. With friendly guides, chances to see dolphins, and the spectacular caves, it’s a good-value option—especially if you’re trying to tick off multiple highlights in just a few hours.
However, be prepared for large crowds, some organizational hiccups, and limitations on how close you can get to certain caves. It’s a lively, scenic boat ride that prioritizes ease and fun, making it perfect for travelers who want a hassle-free introduction to the coast’s natural wonders.
To sum it up, if you love the idea of a quick adventure that combines scenic views, wildlife, and cave exploration, this tour will serve you well. But if you’re seeking a quieter, more detailed, or personalized experience, consider other options or tours that might offer smaller groups or longer durations.
