Ajaccio: Cruise to Sanguinaires Islands with Mezzu Mare Stop

The best part of this Ajaccio boat trip is the short run to Mezzu Mare, the largest of the four Sanguinaires Islands. In less than 30 minutes, you leave the port behind and reach a wild, uninhabited island with a lighthouse, old semaphore, and ruins to explore on foot.

I like the two-hour island stop, which gives you time to walk rather than simply circle the rocks from the water. I also like the chance to swim in clear turquoise water. The main drawback is that the boat moves at about 25 to 30 knots, so this is not a good choice if you are prone to seasickness. The French-only operation may also require patience if you do not speak the language.

Key points at a glance

• Mezzu Mare is the main event: You get a two-hour stop on the archipelago’s largest island, not just a passing view from the boat.
• The lighthouse walk is short but worthwhile: A path rises to about 80 meters, with views across the islands and sea.
• Swimming is part of the appeal: Bring beachwear for a pause in the turquoise water.
• The islands are wild and uninhabited: Expect natural scenery and ruins, not shops, restaurants, or built attractions.
• The ride takes less than 30 minutes from Ajaccio: Most of the outing is spent around the islands and on Mezzu Mare.
• The boat is brisk, not extreme: Cruising speed is around 25 to 30 knots, or roughly 50 kilometers per hour.

Leaving Ajaccio for the Sanguinaires Islands

Ajaccio gives you an easy starting point for seeing one of Corsica’s most striking coastal sights. The Sanguinaires archipelago sits less than 30 minutes from the port by boat, close enough for a half-day outing but far enough to feel separate from the city.

The archipelago consists of four islands. They are uninhabited and wild, which gives the trip a clear sense of place. You are not heading to a resort island with cafés and souvenir stalls. You are going to a bare, dramatic corner of the Mediterranean where the main attractions are rock, sea, old structures, and open views.

The boat ride is also part of the experience. At a cruising speed of around 25 to 30 knots, the crossing should feel lively without being an extreme-speed ride. The operator specifically notes that the boats do not run at frightening or uncomfortable top speeds. Still, the sea can affect people differently, and anyone prone to motion sickness should think carefully before booking.

Your driver speaks French. If you understand French, you will be in the best position to follow instructions and any commentary. If not, plan to pay close attention to the practical directions, especially when moving around the boat or preparing to step ashore.

A close look at all four islands from the water

The approach to the Sanguinaires Islands is one of the strongest parts of the outing. From the boat, you can take in the group as a whole before landing on Mezzu Mare.

The islands have an austere, untouched feel. Their appeal comes from the contrast between dark rock, bright sea, and open sky. The scenery changes as the boat moves around the archipelago, so the ride offers a better sense of the area than a single viewpoint on land.

You will also have a chance to admire the Calanques from the boat. These coastal rock formations add another layer to the trip, especially if you enjoy seeing how Corsica’s shoreline changes from one section to the next.

This portion is best for people who enjoy a moving view rather than a tightly scheduled sightseeing program. There is no suggestion of a long guided lecture or a series of formal stops. The value comes from the setting itself and from being able to reach an area that is accessible only by sea.

Bring sun protection and keep your camera ready, but do not let photography take over. The most memorable views are likely to come in quick shifts as the boat passes the coast and islands.

Two hours on Mezzu Mare

Mezzu Mare is the largest island in the group and the only place where you spend substantial time ashore. The two-hour stop gives you enough room to walk, look around, and enjoy the water without having to rush through a brief landing.

The island is described as wild and completely uninhabited. That matters when setting expectations. You should not count on food, drinks, shops, changing facilities, or other visitor services. Pack what you need before departure, since food and beverages are not included.

The walk to the lighthouse and old semaphore takes only a few meters of climbing, but the highest point reaches about 80 meters. That rise gives you a useful reward for a relatively small effort. From above, you can look across the island group and the sea, with the boat and coastline providing a sense of scale below.

The old semaphore is a particularly interesting stop because it connects the island to its working past. The lighthouse gives you a second point of interest, while the ruins of the Lazaretto add a reminder that these islands were not always simply a scenic stop for boat passengers.

You should wear practical footwear if you plan to walk up to the higher points. The supplied information does not describe the path in detail, so do not assume it is a paved promenade. The climb is short, but the setting is natural and exposed.

The lighthouse, semaphore, and Lazaretto ruins

The island’s attractions are modest in size but strong in atmosphere. You are not visiting a large museum or a restored historic complex. Instead, you see remnants in their original setting, surrounded by sea and open air.

The lighthouse makes a natural goal for your walk. It gives the stop a clear purpose and helps you see more of the archipelago from above. The old semaphore offers another landmark nearby, while the Lazaretto ruins make the island feel like more than a pretty swimming stop.

I like this mix because it gives the outing some substance. A boat trip that only circles rocks can feel short once the novelty wears off. Here, you can combine a brief walk, old structures, and wide views with time by the water.

The historic remains are not described as fully restored or presented with a large amount of interpretation. You should approach them as atmospheric ruins rather than a formal historic site. The appeal is in seeing them where they are, with no city streets or modern buildings competing for attention.

Take your time on the high point, especially if the weather is clear. The panorama is one of the main reasons to get off the boat. You will see more by walking a little than by staying at the landing area.

Swimming in turquoise water

The excursion includes a pause for swimming, so bring beachwear even if you mainly booked for the scenery. The clear water is a major reason this trip works as a relaxed half-day outing rather than a simple sightseeing transfer.

Swimming conditions can vary with weather and sea conditions, and no details are provided about the exact length or location of the swim stop. Treat it as an opportunity rather than a guarantee of a long beach session.

You should also remember that Mezzu Mare is uninhabited. Do not expect a sandy beach, rental equipment, a snack bar, or a staffed swimming area unless the operator says otherwise at the time of booking. The appeal is a natural setting, not resort comfort.

A simple approach works best: wear or pack your swimsuit, bring a towel, and carry any water or snack you want for the three-hour outing. Food and drink are not included. The boat provides a life jacket, but that does not replace bringing your own sun protection and personal essentials.

If you prefer to stay dry, the swim pause does not erase the other parts of the trip. You can focus on the boat ride, coastal views, and island walk instead. If swimming is the main reason you are interested, confirm the day’s conditions and exact swim arrangements before setting out.

How the boat ride affects comfort

The stated speed of 25 to 30 knots, around 50 kilometers per hour, makes the ride quick and efficient. You reach the archipelago in under 30 minutes, leaving most of the three-hour outing for the islands.

That speed can also mean wind, spray, and movement. People who enjoy a brisk open-water ride will probably find it part of the fun. People who get seasick easily are specifically advised not to take this trip.

You may want to eat lightly before departure and avoid booking if rough water usually troubles you. The information does not say whether the boat has indoor seating, shade, or a toilet, so you should not count on those features without checking.

A past outing also included a small issue with instructions around the boat’s fender. The guide became forceful when a passenger walked before being told to do so. The practical lesson is simple: wait for clear permission before moving around the boat or stepping ashore, even if the procedure seems obvious. Paying attention to the crew’s directions will help keep the start of the trip calm.

The boat itself has been praised as beautiful, and the setting earns much of the positive attention. Still, the experience is better suited to people comfortable with a direct, active boat operation than to anyone seeking a polished, highly scripted cruise.

What $57 means for the value

At $57 per person, this is priced as a focused half-day excursion rather than a full-day charter. You are paying for the boat ride from Ajaccio, the return journey, access to a sea-only destination, the Mezzu Mare stop, and the chance to swim and walk to the island’s high point.

The price makes the most sense if you value access. The Sanguinaires Islands cannot be reached by road or on foot, and the boat removes the need to arrange separate transport, timing, and a landing plan.

The value is weaker if you want a long guided history tour, included meals, or a fully equipped beach day. Food and drinks cost extra, and the islands do not offer the services you would find on a developed coastal excursion.

For many visitors, the three-hour length is a practical advantage. You see a major natural attraction without giving up an entire day in Ajaccio. It can fit neatly into a port visit or a short Corsica stay, provided the departure time works with your schedule.

The overall rating is 3.9 out of 5 from 17 ratings. That suggests a generally worthwhile experience with some room for improvement, rather than a flawless tour. The strongest reasons to book are the beautiful boat, the island scenery, the two-hour landing, and the swim stop. The main cautions are sea comfort, French-only operation, and the lack of included food or drink.

Who should book this Ajaccio cruise

I would choose this trip if you want to see the Sanguinaires Islands properly rather than simply photograph them from Ajaccio. The two-hour stop makes it more satisfying than a short coastal cruise, and the lighthouse walk gives you a clear point of interest.

It suits you best if you:

• Enjoy open-water boat rides
• Want time to swim in a natural setting
• Like short walks to viewpoints
• Are comfortable visiting uninhabited places without services
• Can follow French instructions
• Have at least three hours available in Ajaccio

I would be cautious if you are pregnant, under seven years old, or prone to seasickness, since the activity is specifically not suitable for those groups. You should also reconsider it if you need a quiet, slow boat ride or a fully accessible waterfront experience.

The tour may work well for couples, active adults, and families with older children who can handle the boat and walk. It is less suitable for anyone expecting a gentle harbor cruise with frequent comforts.

Planning your three hours

Wear beachwear and choose practical clothing for a boat and a short island walk. Bring water, snacks, a towel, and sun protection because food and drinks are not included and there are no stated services on Mezzu Mare.

Keep your schedule flexible around the stated three-hour duration. Starting times vary, so check availability before booking. If you are arriving by cruise ship, allow enough time to get from the ship to the departure point and back. The supplied information does not provide a meeting point, so confirm that detail before payment.

The cancellation information needs careful attention. One set of booking terms says you can cancel up to 24 hours in advance for a full refund, while the important information also says cancellations under 72 hours may be charged in full. Because those time limits conflict, check the current terms shown for your selected departure before you commit.

The reserve-now-and-pay-later option can help if your schedule is still changing. It lets you hold a place without paying immediately, but it does not remove the need to check the cancellation deadline.

Should you book the Mezzu Mare trip?

Book it if the idea of a wild island stop with a lighthouse walk and a swim sounds better than a city tour. The short crossing, two-hour visit, and high viewpoint give you a good amount of scenery for a three-hour outing.

Skip it if seasickness is a concern, if you need a developed beach with facilities, or if you want an English-language guide. Also confirm the cancellation rule before booking, since the stated deadlines differ.

For the right person, $57 is fair value. You get access to a sea-only corner of Corsica, time to explore Mezzu Mare, and a boat ride that covers both the coast and the islands. Just bring your own food and water, listen closely to the crew, and treat the outing as a natural adventure rather than a resort excursion.
