Full Day 3-Island Boat Cruise from Port of Kos

Dolphins near the fish farms, a swim in clear water by Plati, and a Greek barbecue served on deck make this a full day at sea with plenty of variety. From Kos, you reach Vathi on Kalymnos, stop near Plati for swimming, and finish at the small island of Pserimos.

I like the way the trip combines scenery with useful free time. You get about an hour at each stop rather than simply sailing past the islands, and the crew keeps lunch, drinks, and the schedule moving. I also like the price: at $36.28 per person, it gives you a boat day, two island visits, a swim stop, and lunch without the cost of arranging separate transport.

The main drawback is comfort. The boat can feel full, seating is basic, and much of the journey is spent in the sun. If you want a quiet, spacious yacht with plenty of room to stretch out, this is not that boat. Arrive early if shade matters to you, and bring sunscreen, water money, and something to secure your hat.

Key points to know before you book

• Three named stops, but two island visits: You explore Vathi on Kalymnos and Pserimos, while Plati is mainly a swimming stop from the boat.
• Dolphins are a possible highlight: The boat passes fish farms where wild dolphins are often seen jumping near the water.
• Lunch is included: Expect pork or chicken souvlaki, salad, tzatziki, and bread, with a vegetarian plate available.
• The boat day is long: The cruise runs about 7 hours and 15 minutes, leaving Kos at 10:00 am and returning to the same port.
• Shade and seating are limited: Early arrival is useful, especially in hot weather and during the busiest season.
• The mood is relaxed but not silent: Music plays throughout the day, and the onboard bar sells cocktails, beer, soft drinks, and bottled water.

What the $36.28 price really buys you

At $36.28, this is one of the more economical ways to get a taste of the islands around Kos. The price covers the cruise and a barbecue lunch, while the boat also provides time to swim and go ashore. You are paying for a broad day out, not a private boat or a polished luxury sailing trip.

The value is strongest if you want to see several places in one day and do not want to arrange ferries, taxis, and meals separately. The boat handles the transport, the crew explains when to return, and the food is served onboard. That removes much of the guesswork from a day that could otherwise become awkward to organize.

You should still set aside extra money for drinks and snacks. Alcohol, soda, and bottled water are not included. Prices cited onboard include small beers around €3.50 and cocktails around €6, though exact prices can change. The bar is part of the experience, but it also means your final cost will be higher than the advertised fare if you plan to drink.

This is a large group cruise, with capacity for up to 135 people. That helps keep the price low, but it also explains the crowded seating and occasional noise. I would judge the value as very good for an active day with simple comforts, less attractive if your priority is space and peace.

Leaving Kos at 10:00 am

The meeting point is at the Port of Kos, and the activity ends back there. The scheduled start is 10:00 am, with a total duration of roughly 7 hours and 15 minutes. That makes it easy to plan as your main daytime activity, but it is too long to combine comfortably with another major excursion.

The journey to the first stop and the return run can feel long. Much of the day is spent moving between destinations, so bring sunscreen and prepare for plenty of open-air time. The boat has music and a bar, which helps fill the longer stretches, but this is still a day on the water rather than a quick island shuttle.

Arrive early if you want the best chance of finding a shaded place. Seating is not reserved, and some areas can be exposed to direct sun for long periods. A hat is useful, but tie it down because the wind can carry it away.

The atmosphere is generally family-friendly and relaxed. A four-year-old can take part in the main activities, though parents will need to keep a close eye on children around the boat, the swim stop, and the hot deck. Music can be loud at times, especially when the boat is busy.

Entering Vathi’s natural fjord on Kalymnos

The first stop is Vathi, a village on Kalymnos reached through a striking natural fjord. As the boat moves into the narrow inlet, the valley opens gradually, with surrounding gulfs and caves providing the best views of the morning.

You have about one hour ashore. That is enough for a short walk through the peaceful streets, a local orange juice, or a sweet from one of the small businesses. Vathi is not a place for a long museum visit or a packed sightseeing program. Its appeal is the setting and the slower pace.

The sponge warehouses add a useful local detail. Kalymnos is closely linked with sponge fishing, and these warehouses offer a glimpse of the island’s working past. You do not get an extended historical tour, but even a short look helps explain why Kalymnos has a character different from a simple beach stop.

An hour goes quickly. I would use it for a walk, photographs, and a drink rather than trying to cover every corner. Stay aware of the departure time, since the boat cannot wait for late returnees.

Vathi is one of the more scenic parts of the day, but expectations matter. You are not getting a full Kalymnos excursion. You are getting a short introduction to one village, framed by a memorable approach through the fjord.

Dolphin watching near the fish farms

After Vathi, the boat heads toward Plati and passes nearby fish farms. Fish attract wild dolphins, and the crew may spot them leaping alongside the boat. This is not a guaranteed wildlife show, but it can become the day’s most memorable moment when the dolphins appear.

The captain has sometimes adjusted the route after receiving word of dolphin sightings. That kind of flexibility is valuable, although nature always sets the rules. Keep your camera ready, but do not spend the entire crossing staring through a screen. Dolphin sightings can be brief, and they may appear on either side of the boat.

There is no promise of a particular number of dolphins or a fixed viewing time. You should treat this as a fortunate possibility rather than the main reason to book. Still, seeing wild dolphins in open water adds something a standard island transfer cannot provide.

Swimming in the clear water near Plati

Near the islet of Plati, the boat anchors close to shore and shuts off its engines. This becomes the main swimming break of the day. The water is clear enough to see the sandy bottom through blue and turquoise tones, making the stop especially appealing on a hot day.

You can jump from the side of the boat or use a ladder. The jump may be from a height that feels uncomfortable if you are not a confident swimmer. The ladder offers a gentler entry, but it still requires you to climb down into open water.

This is an important practical point: the swim stop is not equally easy for everyone. If you are unsure about jumping, wait for the ladder and ask the crew for help. If neither option feels right, you can remain onboard and enjoy the view.

Bring swimwear, a towel, sunscreen, and a secure place for small belongings. The water may be the clearest you see all day, but the boat deck can become slippery when people return from swimming.

While the engines are off, happy hour begins. Cocktails are sold at low prices, with drinks often around €6. The bar adds a social touch, but the alcohol is not included in the tour price. You can swim, sit on deck, or simply watch the water while the boat rests.

Greek barbecue lunch on deck

Lunch includes pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian option includes beans, dolmades, salad, tzatziki, and bread. The meal is simple Greek fare, but it fits the setting and gives you something substantial during a long day outdoors.

The food receives especially strong praise for being better than expected on a boat. Some people find it basic, which is fair. You are not stopping at a waterfront restaurant, and there is no choice of a full menu. The advantage is speed: everyone eats onboard without losing more island time.

Vegetarians are catered for, but you should make your preference clear when needed. The provided vegetarian plate gives you a proper meal rather than leaving you with only salad and bread.

The barbecue is part of the value calculation. A full day at sea can become expensive if you need to buy lunch for yourself, so having the main meal included makes the $36.28 price more convincing. You will still want extra money for beverages.

One hour on quiet Pserimos

The final stop is Pserimos, a small island with only about 15 families living there during winter. Summer brings more people, but it remains a modest place compared with Kos or Kalymnos.

You have one hour to explore. The shallow sandy beach is suited to a quick swim, while small paths and a local café or taverna offer a slower alternative. Pserimos is best approached as a simple island pause, not a destination filled with major sights.

Some people find the island beautiful and relaxing. Others may feel there is not much to see beyond the beach, paths, and cafés. Both impressions can be true. The value here comes from the quiet scale and the chance to step off the boat, not from a long list of attractions.

Use the hour according to your mood. Swim if the water is calm, walk a little, or sit with a drink and watch the boats. If you try to do everything, you will spend most of the stop checking the clock.

After Pserimos, the boat returns to Kos. The final run can feel tiring, especially after a full day in the sun. Still, the combination of island stops, swimming, lunch, music, and possible dolphins gives the cruise a satisfying range.

Comfort, music, and the onboard bar

This is an authentic, practical boat trip rather than a luxury cruise. Seating can be uncomfortable over several hours, and the boat may feel packed in the high season. If you care about personal space, arrive early and choose your position carefully.

Music plays during the cruise and helps create a holiday mood. It can also be too loud for some people. The atmosphere depends partly on the group onboard, so a large or noisy group can change the feel of the day.

The bar sells cocktails, beer, soda, bottled water, and snacks. Prices are described as reasonable, and the low-cost cocktails are a popular part of the cruise. Bring cash, since it is specifically useful for purchases onboard and at the island stops.

To make the day easier, pack:

• Sunscreen and a hat that can be secured
• Swimwear and a towel
• Cash for drinks, snacks, and island cafés
• A phone or camera with enough battery
• Water if you prefer not to buy it onboard

Service animals are allowed, and the activity is listed as suitable for most people. Swimming, boarding, and moving around a full boat still require practical judgment. The crew is friendly and helpful, but they cannot remove the physical limits of the boat.

Who should book the Odyssey cruise?

I would recommend this trip to you if you want good value and a varied day without managing island transport yourself. Families, couples, and groups of friends can all find something here, from the fjord at Vathi to the swim near Plati and the beach at Pserimos.

It also suits people who enjoy a social boat atmosphere. The music, bar, lunch, and shared deck create a casual day rather than a quiet sailing retreat. Captain Giannis and the crew are praised for keeping people informed, helping with meals, and responding when dolphins are nearby.

I would hesitate if you dislike crowds, loud music, direct sun, or basic seating. I would also temper expectations if you want extensive sightseeing on each island. With only about an hour at each stop, this is a sampler of the nearby islands, not a detailed cultural tour.

The cruise has a 4.8 rating from 1,133 reviews, with 96 percent recommending it. Those figures fit the experience: the strongest points are the friendly crew, low drink prices, tasty lunch, clear swimming water, and the chance to see dolphins. The recurring weaknesses are limited shade, full seating, long sailing stretches, and the modest amount to do on Pserimos.

Free cancellation is available up to 24 hours before the 10:00 am start. Poor weather or failure to reach the minimum group size can lead to a new date or a full refund.

Should you book it?

Book this cruise if you want to pack several Kos-area highlights into one affordable day. The dolphins are a bonus, not a promise, but the fjord, swimming stop, Greek lunch, and small island visits give you plenty even when nature keeps its distance.

Skip it if you need a spacious boat, gourmet dining, or long, unhurried visits ashore. For most people who arrive prepared for sun, crowds, and basic seating, the Odyssey offers a cheerful and well-priced day on the water.
