Introducing the 3 Hours Aquarium and Margaritas Islands Excursion
If you’re visiting Ibiza and looking for an experience that combines scenic boat rides with interesting local sights, the 3 Hours Aquarium and Margaritas Islands Excursion from San Antonio offers a well-paced glimpse of the northwest coast. Priced at around $40.48 per person, this tour is well-liked, with a solid 4.5-star rating based on 26 reviews, and is typically booked 12 days in advance. It’s roughly a three-hour outing, making it perfect for those who want a taste of Ibiza’s natural beauty without committing a full day.
What I particularly appreciate about this tour is its balance of informative stops and relaxing water time. First, you’ll visit the Cap Blanc Aquarium, a natural cave once used as a fish storage site, now filled with native Ibiza species, giving you a small but meaningful peek into local marine life. Then, for about an hour, you’ll cruise past some of Ibiza’s stunning coves — Cala Gració, Cala Gracioneta, Cala Salda, and Cala Saladeta — offering views that you’ll want to capture and keep. The highlight for many, including eager swimmers from reviews, is the stop at the Margaritas Islands, part of the Ses Balandres natural reserve, where you can swim in clear, inviting waters. Plus, the availability of aquatic gear makes it easy to enjoy the sea even if you’re not a seasoned snorkeler.
One thing to keep in mind is that some reviews mention the small size of the aquarium at Cap Blanc, suggesting if you’re after an extensive marine experience, you might find it a bit limited. Still, the combination of scenic vistas, friendly crew, and included amenities like drinks and snacks helps make this tour feel like good value for the laid-back traveler seeking a short but sweet aquatic adventure.

What to Expect at Each Stop

Here are more great tours and experiences we've reviewed in Ibiza
Cap Blanc Aquarium
This natural cave once served as a fish storage, and now it’s transformed into an aquarium showcasing native ibizan species. It’s a neat way to start the journey, especially since admission is included. It should take around 30 minutes, and although some found it small — “could have skipped that” as one review put it — others enjoyed the close-up view of fish and the cave’s natural beauty. It’s a quick visit but a worthwhile one if you’re interested in local marine life and cave formations.
Scenic Coves and Caves
The boat glides past some of Ibiza’s most picturesque coves—Cala Gració, Cala Gracioneta, Cala Salda, and Cala Saladeta. These spots are praised for their crystal-clear waters and dramatic cliffs, perfect for snapping photos or just zoning out to the sound of the sea. You won’t have long at each one, roughly 10-15 minutes, but the views alone are sufficient to make the journey worthwhile. Several reviews mention how these spots are “very picturesque” and “wonderful,” strengthening their appeal.
Margaritas Islands and Swimming Stop
The final highlight is the visit to Margaritas Islands, part of Ibiza’s natural reserve. Here, you’ll get about an hour to swim and enjoy the waters. The included aquatic equipment—such as snorkel gear—is especially appreciated, allowing even less experienced swimmers to enjoy the sea. One reviewer called the swimming experience “fab,” noting the crystal-clear waters and “perfect” bathing conditions. It’s a relaxing, refreshing way to round off the trip.
