The Santa Maria 3 Island Cruise in the Aegean w/ Free Audio Guide
The best thing about the Santa Maria cruise is how much Aegean variety it fits into one day: a sandy beach on Pserimos, open-water dolphin watching, turquoise swimming near Plati, and a visit to Kalymnos’ small port of Vathy. You get a moving view of the islands without arranging several separate boat trips.
I like the included BBQ lunch, which saves you from packing a meal, and the free audio guide, which gives the sailing some added context without tying you to a live guide. The friendly crew, music, dancing, and generous sunbathing mats also help make the long day feel relaxed.
The main consideration is the size and pace. The boat can carry up to 150 people, and the island stops are short. You will see several places, but you will not have much time to explore each one in depth. Drinks are extra, and you need to meet at the vessel by 9 a.m., 30 minutes before the 9:30 departure.
Key points to know before booking

- Three island stops in one day: Visit Pserimos, Plati, and Kalymnos without arranging separate ferries or excursions.
- Swimming is central to the day: Bring a swimsuit and expect stops designed for beach time and clear-water swimming.
- Dolphin watching is an opportunity, not a guarantee: The boat passes through their natural habitat, but sightings cannot be promised.
- Lunch is cooked aboard: A traditional BBQ is included, with vegetarian and vegan food available if requested ahead of time.
- Vathy adds a taste of local life: Use your free time for orange juice, Kalymnos honey, and a walk around the little port.
- Plan for a full seven-and-a-half hours: The cruise starts and ends at the Kos port, with a maximum group size of 150.
A full Aegean day from Kos

At $30.25 per person, this is priced as an easygoing group excursion rather than a private sailing trip. The value comes from combining transport, several island stops, onboard lunch, a restroom, WiFi, and the audio guide in one fare.
You meet at Kos Cruise Experts at the port and should go directly to the vessel no later than 9 a.m. That early arrival matters because boarding and seat selection take place before departure. If you want a particular place to sit, arriving on time gives you a better chance of choosing it.
The cruise lasts about seven hours and 30 minutes. That is long enough for a proper day on the water, but it also means you should prepare for sun, wind, and a fairly active schedule. The boat has sunbathing mats, and you can use the open-water stretches between stops to relax rather than treating every minute as sightseeing time.
The free audio guide works through your smartphone and is offered in several languages. Bring a charged phone and, ideally, headphones. The guide is useful if you want more background as you sail, though the strongest parts of the day are the physical experiences: beaches, swimming, island views, and time in port.

Pserimos brings the first beach stop
The first stop is Pserimos, a small island with an enchanting sandy beach and few shops. You get about 40 minutes here, so think of it as a quick chance to settle into the Aegean rather than a full island visit.
I like this opening stop because it gets you off the boat early and gives the day a simple start. You can walk along the beach, swim, explore a little, or buy an ice cream. With only a small amount of commercial activity, Pserimos feels more like a beach pause than a developed resort stop.
That short time also creates the first tradeoff. Forty minutes passes quickly once you walk from the landing area, find a spot, and get into the water. If you want to swim, skip a long walk and head straight for the beach. If you prefer to explore, accept that your beach time will be limited.
Pserimos is best for people who enjoy a brief taste of a quiet island. It is not the place to expect a long café lunch, extensive shopping, or a packed sightseeing program.
Kalymnos waters offer a chance to see dolphins

After Pserimos, the boat makes a 20-minute dolphin-watching stop near Kalymnos. The cruise passes through the animals’ natural habitat, giving you a chance to watch the water and scan the horizon.
It is important to keep expectations sensible. Dolphin watching is not a scheduled animal performance, and no sighting can be guaranteed. Treat it as a pleasant possibility during the journey, not the one feature that must make the day worthwhile.
This short stop can still be memorable. Keep your phone or camera ready, but do not spend the whole time staring at a screen. You will want to watch the water, listen for announcements from the crew, and enjoy the wider Aegean view.
Because the stop lasts only 20 minutes, it does not add much strain to the schedule. It is a compact wildlife-watching moment between the beach and swimming portions of the cruise.
Plati is all about turquoise water

The next stop is tiny Plati, where you have about 40 minutes for swimming in clear turquoise water and optional jumps from the cliffs. This is one of the more active sections of the day, but you can simply remain on the boat or swim at your own comfort level if you do not want to jump.
Bring a swimsuit, towel, and sun protection. The swimming stop is a major reason to book this cruise, and you will get more from it if you are ready to enter the water quickly. Since the time is limited, changing facilities may be less convenient than they are on land, so arrive prepared.
Plati is not presented as a long walking stop. Its appeal is the water, the small-island setting, and the chance to cool off from the sun. If your ideal boat trip includes several swims, this stop fits well. If you prefer museums, long walks, or detailed island tours, it may feel too brief.
The optional cliff jumps also make this a stop with different levels of activity. You can watch others, sunbathe, or swim instead. The important point is not to feel pressured to take part in every activity.

Vathy gives the day its local flavor

The Kalymnos stop takes you into the small port of Vathy, where you have about one hour and 20 minutes. Compared with the quick beach pauses, this is the most substantial chance to walk around, sample local tastes, and get a sense of an inhabited island community.
You can look for freshly squeezed orange juice and Kalymnos honey, two specific treats called out for this visit. These purchases cost extra, but they give the stop a local focus instead of turning it into another generic beach break.
The timing here is useful because it combines land time and water time. You can explore the town first, then swim in the refreshing water before returning to the boat for lunch. Keep an eye on the meeting time, since the stop includes several tempting distractions and the boat cannot wait for a late return.
Vathy may be the most rewarding stop for you if you want something beyond swimming. It still is not a full cultural tour of Kalymnos, but the port visit gives the day more balance. You get a glimpse of local food and daily life along with the sea views.
The BBQ lunch is practical, not a luxury meal

A traditional BBQ lunch is served aboard the boat after the Vathy stop. That is a strong value point at this price because you do not need to buy lunch during the day or carry food supplies from Kos.
The meal is cooked and served on the vessel, making it easy to eat without giving up more island time. Vegetarian and vegan options are available, but you need to request them ahead of time. Do not wait until boarding to mention a special diet.
Beverages are not included. Alcoholic drinks, bottled water, and other drinks cost extra, so bring money for refreshments. Alcohol is limited to people aged 18 and over. Since the cruise is long and includes swimming in warm weather, planning for your water needs is especially sensible.
Lunch is best understood as a convenient group meal rather than a restaurant experience. It supports the day’s schedule and keeps the price down. If you have strict dietary needs, confirm your request before departure and carry any essential snacks you may need.
Music and the boat atmosphere

The cruise is not only about getting from one island to another. Music and dancing are part of the onboard atmosphere, and the crew is described as friendly and helpful. That can make the return sailing lively rather than simply a long ride back to Kos.
The same atmosphere will not suit everyone equally. If you want a quiet private sail, a boat carrying up to 150 people may feel too social. If you like a cheerful group setting, music, and a little dancing after swimming and lunch, the mood should fit.
The sunbathing mats are a useful detail. They give you a more comfortable way to rest during the sailing portions, especially after the active stops. Still, space and seating are shared, which is another reason to arrive 30 minutes early and select your seat before departure.
WiFi and a restroom are available onboard. Those are modest but practical comforts on a seven-and-a-half-hour outing. WiFi may help you stay connected, while the restroom saves you from depending only on facilities at the island stops.
What the $30.25 price really covers

At $30.25, the cruise offers strong value if you want a simple way to see several islands from Kos. The fare includes the boat trip, the island stops, lunch, the restroom, WiFi, and the smartphone audio guide. It also removes the planning work involved in finding separate transport between the islands.
The price does not cover drinks, alcohol, bottled water, ice cream, orange juice, honey, souvenirs, or other items bought ashore. Your total cost will therefore be higher if you want several refreshments or local products.
The group size is the biggest factor in judging the price. A maximum of 150 people means you are paying for a shared day, not privacy or personal attention. In return, you get a broad itinerary at a low cost. The cruise works particularly well for couples, families, and friends who want variety without spending heavily.
The tour is booked, on average, about five days before departure. That suggests you should not assume you can wait until the last morning during a busy Kos holiday. Confirmation is provided at booking, and group discounts are available.
Who will enjoy the Santa Maria most
I would recommend this cruise to you if you want three things in one day: island scenery, swimming, and a social boat atmosphere. It is also a practical choice if you are staying in Kos and want to reach Pserimos, Plati, and Kalymnos without handling the transport yourself.
It suits people who enjoy short stops rather than one long stay in one place. You will move from beach to dolphin-watching waters to a swimming spot and then a port visit. That variety keeps the day moving, but it leaves little room for unplanned wandering.
Families may appreciate the mix of beach time, swimming, lunch, music, and a manageable price. People who dislike crowds, prefer silence, or want a carefully guided cultural tour should think twice about the boat capacity and the quick island visits.
Most people can participate, and the vessel has a restroom. Still, the schedule includes boarding, beach access, swimming, and time on small islands. If you have mobility concerns, contact the operator before booking because the available information does not describe specific accessibility arrangements.
You should also be comfortable with the possibility that weather can change the plan. The cruise requires good weather. If poor conditions cancel it, you are offered another date or a full refund. A minimum number of participants is also required, and a cancellation for that reason brings the choice of another date or experience, or a full refund.
Booking and cancellation details to keep handy
The cruise begins at 9:30 a.m. from Kos Cruise Experts at the Port of Kos and returns to the same meeting point. Meet the crew at the vessel by 9 a.m. at the latest for boarding and seat selection.
Free cancellation is available if you cancel at least 24 hours before the local start time. Cancellations or changes made less than 24 hours before departure are not accepted for a refund.
The company may photograph or record people during the cruise for promotional, marketing, advertising, or documentation use. If you do not want to appear in those materials, tell the crew before departure.
Should you book this Kos island cruise?
Book it if you want an affordable, full-day sampler of the Aegean with plenty of swimming, a BBQ lunch, and a friendly group mood. The strongest reasons are the three-island route, the included meal, the useful onboard facilities, and the chance to visit Vathy rather than spending the entire day on deck.
Skip it if you want deep exploration of one island, a private boat, guaranteed dolphin sightings, or a quiet luxury experience. The stops are short, the group can be large, and drinks cost extra.
For many people staying in Kos, this is a sensible way to turn one day into a broad Aegean outing. Arrive early, bring swim gear and money for drinks, request dietary needs ahead of time, and use the audio guide as a bonus rather than the main event.
