Ibiza: Boat Trip to Margaritas Islands and Aquarium Ticket

Sea views, swimming, and snacks fill three easy hours. This family-friendly cruise from San Antonio combines a coastal sightseeing trip with a stop at Aquarium Cap Blanc and an open-water swim near the Margaritas Islands. I like the generous drinks service, which includes water, soft drinks, beer, sangria, and white wine, and I like that snorkels, floats, flippers, and pool noodles are available at no extra charge. The main consideration is weather: rough conditions can prevent the boat from reaching the Margaritas Islands.

The cruise also gives you a different view of Ibiza’s west coast, including Cala Gració, Cala Gracioneta, Cala Salada, and Cala Saladeta. I especially appreciate the short three-hour format, since you get a real taste of the coast without losing an entire day. The aquarium visit is fairly brief, and the lower-deck glass-bottom viewing area can feel hot, so this is best seen as a pleasant sea outing with several stops rather than a major aquarium tour.

The best parts of the trip at a glance

• Aquarium Cap Blanc: See Mediterranean sea life inside a natural sea cave where seawater flows in from the coast.
• Margaritas Islands swim stop: Spend time in clear water near rocky islets in a protected area.
• Included drinks: Water, soft drinks, beer, sangria, and white wine are served during the cruise.
• Useful water gear: Snorkels, masks, flippers, floats, and pool noodles are available for the swimming stop.
• West-coast sightseeing: Pass Cala Gració, Cala Gracioneta, Cala Salada, Cala Saladeta, caves, cliffs, and small islets.
• Good family timing: The three-hour schedule feels manageable, including for families with young children.

Why this short Ibiza cruise works well

Ibiza is easy to admire from a beach, but the west coast makes more sense from the water. Cliffs, sea caves, small rocky islets, and coves are often difficult to reach on foot. This trip lets you see several famous spots in one outing without arranging a car, beach transfer, or separate boat rental.

The catamaran is designed for relaxed sightseeing rather than speed. You can sit on the upper deck for open views or go below to look through the glass-bottom windows. The lower area offers a closer look at the seabed, though it may feel warm, so most people will probably prefer short visits below deck.

The atmosphere is casual. Music plays during parts of the cruise, and the guide provides information about points along the coast. The commentary is offered in English and Spanish. If the public-address system has trouble, as happened on one outing, the guides work to keep the information going, but some details may be harder to hear over the engine and water.

At $46 per person, the trip offers more than a basic sightseeing cruise. You receive the catamaran ride, aquarium entry, a swim stop, drinks, snacks, water equipment, and a restroom on board. That combination makes the price especially fair for families, since you do not need to buy drinks at every stage or rent basic swimming gear separately.

Meeting Captain Nemo in San Antonio

The departure point is Capitán Nemo Ibiza on the San Antonio promenade. Redeem your ticket at the Nautilus Ibiza counter, using the wooden booths directly in front of the boat. Look for the booth marked CAPITAN NEMO, positioned near the large fountain.

Allow enough time to find the counter before departure. The meeting point is central, but the promenade has several booths and boat operators, so checking the name carefully saves confusion. Bring your booking details and wear comfortable clothing suited to both sitting on a boat and swimming later.

You should pack sunscreen, sunglasses, swimwear, a towel, a camera, flip-flops, and comfortable beach clothing. Sunscreen and towels are not supplied. I would apply sunscreen before boarding and bring extra for the return trip, since the open deck gives you plenty of sun exposure.

There is an indoor bar and an onboard restroom. Those details matter on a three-hour boat trip, especially for families with children. The included drinks are served throughout the outing, and one practical touch is a reusable plastic cup provided when you board, which you can use for the complimentary drinks.

The first 30 minutes along Ibiza’s west coast

The trip begins with a sightseeing cruise lasting about 30 minutes. This opening stretch helps you settle into the boat and gives you a broad view of San Antonio’s coastal surroundings before the first stop.

You pass rocky shorelines and coves that are hard to appreciate from land. The guide points out places along the route and shares local information as the boat moves toward Aquarium Cap Blanc. The pace is gentle enough for photographs, though the best views may depend on where you sit and how busy the boat is.

I would use this first section to get your bearings. Find a comfortable place on the upper deck, note where the bar and restroom are, and keep your camera ready. You will want to shift around during the cruise because the best view changes as the boat turns along the coast.

Aquarium Cap Blanc, a sea cave with a local purpose

Aquarium Cap Blanc is not a conventional aquarium in a large modern building. It occupies a natural sea cave in the cliff, with seawater flowing into the cave and creating a habitat for local marine life. That setting is the real attraction.

You spend about 20 minutes viewing Mediterranean species and learning about the seabed around Ibiza. The visit gives the trip a small educational element, which helps distinguish it from a simple party cruise. Children often enjoy the enclosed cave and the chance to see native sea life at close range.

Keep your expectations in proportion. Twenty minutes is enough for a quick look, but not enough for a long museum-style visit. The aquarium is one part of a wider outing, not the main event. A child who loves marine life may want more time, while someone mainly interested in swimming will probably find the stop just right.

The boat also has glass-bottom windows on the lower deck, allowing you to look into the water during the journey. The area can be hot, so I would make a brief visit rather than plan to sit there for the whole cruise.

Cala Gració, Cala Salada, and the coastal sightseeing route

After the aquarium, the boat spends about 40 minutes cruising past some of the west coast’s best-known coves. Cala Gració and Cala Gracioneta are known for clear water and golden sand. Cala Salada and Cala Saladeta add more rocky scenery, small bays, and protected coastal views.

This part of the trip is about seeing Ibiza from a wider angle. From the boat, you can notice how the coves fit into the cliffs and how small the beaches look compared with their reputation on land. You also pass sea caves, rock formations, and small islets connected with protected coastal areas.

The guide’s commentary gives useful context, especially if you have not explored this side of Ibiza before. It is not a formal lecture, and the cruise remains light and social. You get enough information to identify the main places without losing the relaxed feel of the outing.

The coast is also one reason to bring a camera, though strong sunlight can make photographs tricky. Sunglasses are useful even if you plan to spend most of your time seated. The upper deck offers the clearest view, while the lower deck gives shelter and access to the glass-bottom windows.

Ses Balandres and the main swim stop

The itinerary includes about 30 minutes at Ses Balandres for swimming and snorkelling. This is the most active part of the trip and the point when the outing shifts from sightseeing to recreation.

The water equipment supplied on board includes snorkels, masks, flippers, floats, and pool noodles. That is a real saving, particularly for families. You can try snorkelling without packing bulky equipment or paying a separate hire charge.

The stop is in open water, so you need to be comfortable entering the sea from the boat. Crew members pay attention to swimmers, and the equipment gives children and less confident swimmers extra support, although normal care is still needed. The water may feel chilly outside the hottest part of summer.

Thirty minutes is enough for a refreshing swim, a little snorkelling, and time to float near the boat. It may feel short if swimming is your main reason for booking. One child-focused family would have preferred longer snorkelling time, so serious snorkellers should treat this as a pleasant sample rather than a dedicated snorkelling trip.

Ses Margalides and the Margaritas Islands

The next stop is at Ses Margalides, also referred to as the Margaritas Islands. These rocky islets sit in a peaceful protected area, surrounded by clear turquoise water. The stop lasts about 20 minutes and includes time for swimming, relaxing, and a light aperitif.

This is the scenic payoff of the cruise. You are away from the more built-up parts of the coast, with open water, rock formations, and a quieter setting. The boat may pause here for swimming or for you to enjoy the surroundings from the deck.

The included refreshments make this stop feel easy. Drinks available throughout the trip include water, soft drinks, beer, sangria, and white wine. Fresh fruit is served after the swim stop, and snacks can include sweets and pastries. Some additional food and treats may be available to buy, such as ice lollies, but the main drinks and light refreshments are included.

Weather can change the plan. Strong conditions may prevent the boat from reaching the Margaritas Islands. That is not a failure of the crew, since sea conditions affect safety and the route. If this stop matters most to you, check the forecast and keep your expectations flexible.

The final 40 minutes back to San Antonio

The return cruise lasts about 40 minutes. It gives you another chance to sit on the upper deck, finish a drink, listen to the commentary, and watch the coast recede.

By this point, the boat has covered several different kinds of scenery: beaches, cliffs, caves, rocky islets, and the open-water swimming area. The return leg is less about adding another attraction and more about enjoying the ride back without rushing.

The three-hour length is one of the trip’s strongest features. You get enough time for an aquarium visit, coastal sightseeing, a swim, and refreshments, but the day remains open for a beach, meal, or evening plans in San Antonio. Families with younger children may find this timing easier than a full-day cruise.

What the $46 price really includes

The $46 fare is good value if you use the included features. A basic boat trip might give you the ride and little else. Here, your ticket includes the catamaran cruise, a guide, Aquarium Cap Blanc entry, drinks, a snack, the swim stop, and water equipment.

The drinks are a major part of the value. You can have water, soft drinks, beer, sangria, or white wine without paying separately each time. Families also benefit from the fruit and child-friendly sweets, while adults can enjoy a drink during the coastal cruise.

There are a few costs and practical items left to you. Towels and sunscreen are not included, and extra food such as ice lollies may cost more. Pack those basics and you can keep additional spending low.

The average rating is 4.4 out of 5 from 233 ratings, which fits the experience well: it is a well-liked, good-value coastal outing, but not a luxury yacht charter or a long snorkelling expedition.

Who should book this boat trip

I would recommend it most to families, couples, and anyone who wants a simple way to see Ibiza’s west coast. Children get an aquarium, music, swimming gear, fruit, and a boat ride with enough variety to keep the outing moving.

It also suits couples who want a relaxed half-day on the water without committing to a full-day sailing program. The included sangria, white wine, and coastal views create an easy holiday mood without requiring much planning.

You may want a different activity if your priority is serious snorkelling, a quiet private boat, or a long visit inside the aquarium. The swim stop is useful but limited, and the aquarium visit is short. The boat also has a social holiday atmosphere rather than a private or secluded feel.

The tour runs with live guides in English and Spanish. Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later, which helps if your Ibiza plans are still moving around. Check the available start times before booking, since the exact departure schedule is not fixed in the activity details.

Should you book the Cap Blanc and Margaritas Islands cruise?

Book it if you want a well-priced, family-friendly sea outing with several experiences packed into three hours. The coastal views, natural sea-cave aquarium, included drinks, and supplied swim gear give you a lot for $46.

I would book early in good weather, bring sunscreen and a towel, and treat the Margaritas Islands stop as weather dependent. Choose a seat on the upper deck for the views, visit the glass-bottom section briefly, and collect water equipment before the swim stop.

This is not Ibiza’s most intimate or adventurous boat experience. It is better than that for some visitors: it is straightforward, cheerful, practical, and easy to fit into a holiday. If that sounds like your kind of day, Capitan Nemo Ibiza offers solid value.
