Aquarium Cap Blanc
Admission included30 min
The Aquarium Cap Blanc, also known as Sa Cova de Ses Llagostes, is a natural cave located on the west coast of Ibiza, used as an aquarium for decades and managed with a focus on marine conservation and education.
It is a former fishermen’s cave built into the cliff, where seawater naturally enters, recreating the natural habitat of local species. During the visit, travelers can observe up close a wide variety of Mediterranean marine life, including groupers, gilt-head bream, sea bass, moray eels, rays, octopuses, and various native fish species, while learning interesting facts about their behavior and the island’s marine ecosystem.
The Aquarium Cap Blanc offers an authentic and educational experience, perfect for understanding Ibiza’s marine biodiversity in a unique natural setting, respectful of the environment and suitable for all ages.
Cala Gracio
Pass by
Cala Gració and Cala Gracioneta are two of the most well-known and appreciated coves on Ibiza’s west coast, located very close to San Antonio and noted for their easy access and natural surroundings.
Cala Gració is a wide, sheltered cove with fine sand and calm waters, perfect for swimming and popular with both locals and visitors. Right next to it is Cala Gracioneta, a smaller, more intimate cove with a special charm thanks to its compact size, golden sand, and crystal-clear waters.
During the excursion, the boat sails close to both coves without stopping, allowing travelers to enjoy a privileged view from the sea. While passing by, the captain shares details and interesting facts about their history, features, natural surroundings, and their importance within the San Antonio bay, offering a unique and peaceful way to discover these iconic spots on Ibiza.
Playa Cala Salada
Pass by
Cala Salada and Cala Saladeta are two gems of Ibiza’s northwest coast, known for their crystal-clear waters, golden sand, and protected natural surroundings. Surrounded by pine trees and cliffs, these coves offer a pristine Mediterranean landscape, perfect for admiring the island’s natural beauty.
During the excursion, the boat sails past both coves without stopping, allowing travelers to enjoy their stunning views from the sea. While passing by, the captain shares details and interesting facts about the formation of the coves, their ecosystem, and their importance within the Ibizan coastline, providing a unique visual and educational experience.
Punta Galera
Pass by
Punta Galera is a prominent rocky headland on Ibiza’s northwest coast, famous for its steep cliffs, unique rock formations, and panoramic views of the Mediterranean Sea. This spot combines a stunning natural landscape with a peaceful, wild environment, perfect for admiring the beauty of Ibiza’s coastline from the sea.
During the excursion, the boat sails close enough to take in the formations and surroundings from the water, offering travelers a different and spectacular perspective of this iconic point on the island.
45 min
The Islas Margaritas, located in the bay of Ses Balandres, are a small group of rocky islets off Ibiza’s west coast, considered a protected natural area of high scenic and ecological value.
This area stands out for its exceptionally clear waters, turquoise hues, and almost untouched surroundings, far from crowds. Thanks to the calmness of the area and the richness of its seabed, it is an ideal spot for swimming and snorkeling.
During the excursion stop, travelers can swim, relax, and enjoy the sea, as well as use the water sports equipment available on board to explore the surroundings. The combination of wild nature, tranquility, and crystal-clear waters makes the Islas Margaritas one of the most special points of the tour and an unforgettable experience for those wanting to discover Ibiza’s most natural side.

Fantastic Value
Fantastic 3 hour excursion with a 5 and 4 year old child. Not too long and fantastic value! It cost us £40 (booked through tripadvisor before leaving the uk and received a discount). £40 for 3 hours of all inclusive beer, wine, sangria, water, soft drinks and snacks. Fresh water melon, some pain au chocolate and apples / bananas.
Kids enjoyed themselves, anything longer would have been a little too much for them.
We were staying at the opposite end of San Antonio, when we asked about a water taxi the lady told us the Nemo would pick us up there instead.
Given the prices for everything I think this is by far the best value trip you can book.
Enjoy!

Must do!
Absolute must do when visiting Ibiza! We went on this trip as a family of 4. 2 boys aged 6 and 12 and we all loved it! Unlimited drinks including soft drinks, beer, sangria and water. Snacks also provided which you just help yourself to. The highlight for us was the free swimming in the sea. When bringing young children who would like to swim I'd recommend bringing some sort of life vest as the water is 15meteres deep. Would definitely book this again the next time we come to Ibiza :)

Bring swim vest or similar for kids. Otherwise fab trip!
We had a lovely day on the glass-bottom boat trip. The staff were friendly and welcoming, and there were plenty of refreshments available throughout the trip, with fresh watermelon after our swim in the sea.
The stops were well planned, and we were lucky enough to see dolphins, tuna, Eleonora’s falcons and explore a couple of caves. The aquarium stop was small but really enjoyable. The glass bottom was nice and clean, so we could clearly see lots of fish when the boat stopped.
The swim stop was great, with a few body boards and pool noodles available to use. If you’re travelling with children who aren’t confident swimmers, I’d recommend bringing a swim vest or similar, as there are only a limited number of flotation aids. We felt very safe in the water, with a lifeguard in a canoe staying close by throughout the swim.

Boat trip with undescribed "extras"
So first, you should look for vouchers from TripAdvisor; we saved another 30%. Then you are supposed to be there 30 minutes early, but they wait until everyone is there or it is 11 o'clock. Then there is information in Spanish and English, occasionally during the trip about what you see on the side. We were only in the aquarium for a short 10-15 minutes, but it wasn't bad since it's quite small. We wouldn't pay admission for it ourselves. On board there is water from a canister or beer / sangria from a chilled tap. Unlimited. Fruit and chocolate rolls were also free. Chips and hot food like hot dogs cost extra.
Restrooms are okay and clean.
Then we had 45 minutes for swimming, which is not in the description at all. Meaning, a handful of people didn't have anything with them and watched for 45 minutes. I think that's a shame. Another minus point is that we were thrown together with another group who received orange wristbands for an extra charge and were dropped off for another 2.5 hours at an overcrowded beach where there was 1 hut and otherwise just nature. Rough. But also back to our time.
During the trip, we were supposed to use the glass bottom as announced, but nothing more came of it, and you didn't really see much anyway. On the way back, we were lucky enough to see a group of dolphins :)
All in all, the unlimited drinks made up for a lot, as did the price with the discount. But once is enough.

Highly recommended
Starting from Sant Antoni de Portmany on a modern catamaran you have the possibility to discover in detail the west coast of Ibiza discovering hidden coves and corners, you will be amazed to see the boat pass between islets that you can almost touch with your hands, see how the height of the cliffs changes while you enjoy a complete explanations by the crew, your mobile or camera will work piecemeal before so much beauty and on the return you can enjoy the possessidoneas at the stop in Cala Salada through its glass bottom and where you will also be presented with a modest but welcome appetizer. Essential.

Excellent mini cruise
We left the port of Sant Antoni de Portmany in a modern catamaran to make this beautiful journey along the west-northwest coast of Ibiza, always sailing close to the coast and at a moderate speed that allowed us to follow the instructions by public address that the crew gave of each area or corner that was visited which made it possible to enjoy full sailing and for more luck the weather accompanied us with sunny day and good temperature. It’s three hours, but they don’t get long because every little cape that bends the boat, every cove that appears in sight and every corner that you discover plus some surprise from the crew make it an unforgettable excursion. Highly recommended.
