Ibiza: Boat Trip to Margaritas Islands and Aquarium Ticket

Ibiza’s best scenery is often viewed from the water, and this three-hour cruise gives you a fine sample without taking up your whole day. You’ll visit Aquarium Cap Blanc, a natural sea cave filled by seawater, then cruise past coves and cliffs before stopping for a swim near the Margaritas Islands.

I like the generous drinks service, which includes water, soft drinks, beer, sangria, and white wine. I also like the easy family setup: snorkels, flippers, floats, and pool noodles are available, while the crew keeps an eye on swimmers. The main consideration is weather. Rough seas can prevent the boat from reaching the Margaritas Islands.

Key points at a glance

• Aquarium Cap Blanc: See Mediterranean sea life inside a natural cave where seawater flows in from the coast.
• West coast views: Cruise past Cala Gració, Cala Gracioneta, Cala Salada, Cala Saladeta, rocky cliffs, caves, and small islets.
• Swim stop: Use the onboard snorkelling gear and floats at Ses Balandres before continuing toward Ses Margalides.
• Good onboard value: Drinks are included throughout the trip, with fruit, light snacks, and an appetizer also provided.
• Family-friendly pace: The 3-hour schedule offers sightseeing, aquarium time, and swimming without turning into a full-day outing.
• Useful practical detail: Redeem your ticket at the Capitán Nemo booth by the large fountain on the San Antonio promenade.

Why this boat trip works so well in Ibiza

At $46 per person, this is priced as an easy half-day outing rather than a luxury cruise. That matters in Ibiza, where a boat trip can quickly become expensive once you add drinks, equipment, and food.

Here, the basic extras are already covered. You receive a catamaran ride, a captain and guide, Aquarium Cap Blanc admission, a swim stop, onboard restroom access, and drinks ranging from soft drinks to sangria and white wine. Fruit, snacks, and an appetizer are also included.

I see the value most clearly for families and couples who want several activities in one booking. You are not paying only for a ride along the coast. You get a short marine visit, a narrated sightseeing cruise, open-water swimming, and time to sit with a drink while the boat moves between stops.

The trip also avoids a common problem with boat excursions: too much time spent simply getting somewhere. Three hours is long enough to feel like a proper outing, but short enough to leave room for the beach, dinner, or an evening in San Antonio.

Starting in San Antonio and finding the boat

The meeting point is at the Nautilus Ibiza counter, in the wooden booths directly in front of the boats. Look for the CAPITAN NEMO booth beside the large fountain on the promenade.

That detail is worth noting because San Antonio’s waterfront has several operators and departure points. Do not simply walk to the marina and hope to spot the right boat. Redeem your ticket at the stated booth first.

The boat has an upper deck and a lower deck, with an indoor bar and restroom onboard. You can settle into the open-air areas for the best views, then move inside if you want shade or a break from the sun.

A plastic cup is provided for drinks during the trip. It is a small but useful touch, especially if you plan to have more than one soft drink, beer, or glass of sangria. Bring your own towel, sunscreen, sunglasses, and swimwear. Towels and suncream are not supplied.

The first 30 minutes: Ibiza from the sea

The opening cruise takes about 30 minutes. From the water, the northwest coast reveals coves, cliffs, small beaches, caves, and rocky formations that are difficult to appreciate from a road or beach path.

The first sights include Cala Gració and Cala Gracioneta. Later, the boat passes Cala Salada and Cala Saladeta, two of the coast’s better-known sandy coves. Their clear water and golden beaches look especially appealing from offshore, where you can take in the shape of the bays without dealing with beach crowds or parking.

The captain or guide provides commentary in English and Spanish. The information adds useful context to the views, though the exact quality of the commentary can depend on the onboard microphone. One past trip had a sound system problem partway through, and the guides compensated by speaking above the engine and waves.

That is not a reason to avoid the trip, but it is a reminder that this is an informal coastal tour rather than a formal lecture. Music is also part of the atmosphere, so expect a relaxed outing with facts and stories mixed into the cruise.

Aquarium Cap Blanc, a sea cave with a purpose

Aquarium Cap Blanc is the first main stop, with about 20 minutes set aside for marine-life viewing. The aquarium occupies a natural sea cave in the cliff, and seawater flows into it naturally.

That setting is the reason the stop feels different from a standard indoor aquarium. You see local Mediterranean species in a coastal environment rather than walking through a large modern exhibition building.

The stop is fairly brief. I would treat it as an unusual introduction to Ibiza’s seabed, not as the central event of the day. If you have children, the cave gives the cruise a clear point of interest early in the outing, and the marine life can make the trip more than a simple sightseeing ride.

One practical point comes from the schedule: the aquarium visit lasts about 20 minutes. If you prefer slow museum visits or want time to study every tank, you may find it short. For most people, especially families with young children, the compact visit helps keep the whole excursion moving.

The lower deck also has glass-bottom viewing windows along the sides. You can go below to look through them, although the enclosed area can become hot, so most people will probably prefer short visits rather than staying there for the whole cruise.

Passing the coves, caves, and rocky coast

After the aquarium, the boat continues along the coast for about 40 minutes. This is the part where you settle into the rhythm of the trip: scenic views, commentary, music, and a drink from the bar.

The coast here is best understood from the water. You see the fronts of cliffs, openings in the rock, small islets, and sheltered coves from angles that are not available on land. The captain points out coastal sites as the catamaran moves along, giving you a clearer sense of how the beaches connect.

I recommend keeping your camera ready, but do not spend the entire cruise looking through it. The most enjoyable part is often the simple change in view as the boat rounds a headland or passes a beach that would be difficult to reach by car.

The open deck is the right place for photographs and fresh air. Comfortable clothes and flip-flops are sensible, but bring a cover-up if you are sensitive to wind or spray. The information provided does not promise a particular seating arrangement, so flexibility is better than expecting a reserved chair.

Ses Balandres and the open-water swim

The itinerary lists about 30 minutes at Ses Balandres for swimming and snorkelling. This is the most active part of the trip, and it is where the boat becomes more than a sightseeing platform.

You can enter the sea from the boat and use the supplied masks, snorkels, flippers, floats, and pool noodles. That saves you from packing a full kit and makes it easier for children or casual swimmers to join in.

The water may feel cool outside the height of summer. One spring outing found the sea chilly, though still inviting. The crew pays attention to swimmers and takes a reassuring, lifeguard-like role, but you should still judge the conditions honestly. This is open-water swimming, not a supervised pool session.

The 30-minute stop is enough for a refreshing swim and a look below the surface, but it may feel short if snorkelling is your main aim. One child who especially enjoyed the snorkelling would have preferred more time. If you want a dedicated snorkelling excursion, choose a specialist trip instead. If you want a scenic cruise with a pleasant swim, this timing is sensible.

Ses Margalides and the Margaritas Islands

The itinerary then allows about 20 minutes at Ses Margalides, described as the Margaritas Islands, for an aperitif, swimming, and local snacks. These small rocky islets sit in a protected area and provide the quietest setting of the cruise.

This is the stop that gives the experience its strongest sense of escape. The water is clear, the setting is open, and the rocky islands create a natural frame around the boat. You can swim, relax, enjoy the refreshments, or simply look back toward Ibiza’s coast.

Weather controls this part of the day. Strong wind or rough water can make it impossible to reach the islands. That happened on one outing, and the guides were not at fault. You should book this trip for the overall cruise rather than treating the Margaritas Islands as a guaranteed promise.

If reaching the islands is your main reason for booking, check the forecast and keep your plans flexible. The boat still offers the aquarium, coastal views, drinks, and another swim opportunity, but the central attraction changes when the sea does not cooperate.

Drinks, snacks, and onboard comfort

The included drinks are one of the clearest reasons this trip offers good value. You can request water, soft drinks, beer, sangria, or white wine during the cruise. That is particularly useful on a sunny day, when buying several drinks separately can quickly add to the cost.

A light snack with fresh fruit is included after the swim stop. Other treats available onboard have included pastries, sweets for children, and additional food for purchase. Ice lollies can also be bought, though they are not part of the included package.

The offer is generous, but I would not book this as a meal cruise. The food is a light accompaniment, not a substitute for lunch. Eat beforehand if you need a full meal, and remember that the included drinks do not mean you should skip water or sensible sun protection.

The indoor bar, restroom, and lower viewing deck make the boat practical for a three-hour outing. Families can move around more easily than they could on a small open boat, while the upper deck gives you the outdoor feel most people want from an Ibiza cruise.

Who will enjoy it most

This is a strong choice for families. Children get the aquarium, music, snacks, a boat ride, and the chance to swim with floats and pool noodles. The three-hour length is manageable, and the crew has been attentive with younger passengers.

Couples will like the balance of sightseeing and downtime. You can sit together with a drink, watch the coves pass by, then join the swim stop without committing to a full day on the water.

It also suits first-time Ibiza visitors who want a quick introduction to the island’s west coast. You will not see every coastal site, but you will cover several famous coves and gain a useful sense of the area from offshore.

I would be less likely to recommend it to someone seeking solitude, a small private boat, or serious snorkelling. The included equipment is convenient, but the main product is a social sightseeing cruise with a swim stop. It is not designed around long time in the water or quiet exploration of the seabed.

Booking details worth knowing

The activity lasts three hours and is offered with live guiding in English and Spanish. You can cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option keeps your plans flexible.

Bring swimwear, a towel, sunscreen, sunglasses, a camera, comfortable clothes, flip-flops, and beachwear. Towels and sunscreen are not included. Alcohol and drugs, littering, and explosive substances are not allowed onboard.

The experience has a 4.4 rating from 233 reviews, which fits the overall picture: strong value, friendly staff, good scenery, and a popular swim stop, with weather and limited swim time as the main variables.

Should you book this Ibiza cruise?

Book it if you want a well-priced, family-friendly coastal outing with several inclusions already covered. The combination of Aquarium Cap Blanc, west coast scenery, drinks, snacks, and water equipment makes $46 a sensible price for three hours.

I would especially choose it early in an Ibiza stay, since it gives you a useful view of Cala Gració, Cala Salada, Ses Balandres, and the Margaritas Islands before you decide which beaches deserve more time from land.

Skip it if you need a private boat, a long snorkelling session, or a guaranteed visit to the Margaritas Islands. For everyone else, this is an easygoing way to see Ibiza from the sea without spending a full day or paying luxury-cruise prices.
