Full Day 3-Island Boat Cruise from Port of Kos
The best part of this Kos boat trip is the mix of three very different stops: a quiet fjord village, a clear-water swim near Plati, and a tiny island beach at Pserimos. You get a full day on the Aegean without arranging ferries, taxis, or separate boat tickets.
I like the strong value at $36.28, especially with lunch included, and I like the friendly crew-led feel aboard Odyssey. Dolphin sightings add a lucky bit of excitement, while the music and bar keep the long crossings from feeling flat.
The catch is comfort. The boat can feel crowded, seats are basic, and much of the day is spent in direct sun. Arrive early for shade, bring sunscreen, and know that the swim stop may require jumping from the boat or using a steep ladder.
Key points to know before boarding

- Vathi gives you one hour in a natural fjord on Kalymnos, with streets, orange juice, sweets, and old sponge warehouses to explore.
- The Plati stop is built around swimming, with clear water, a sandy bottom, and cocktails served during happy hour.
- Pserimos is a small, low-key island, with a shallow beach, walking paths, cafés, and tavernas.
- Dolphin watching is a real possibility, especially near the fish farms, though sightings cannot be guaranteed.
- Lunch includes souvlaki, salad, tzatziki, and bread, with beans and dolmades available for vegetarians.
- The boat holds up to 135 people, so this is a social group cruise, not a quiet private sailing.
Three islands from Kos for $36.28

At $36.28 per person, this is one of the easier ways to see more of the Dodecanese from Kos. The price covers the boat, the island stops, and a Greek BBQ lunch. You still pay for drinks, bottled water, soda, and alcohol, but the onboard prices are described as reasonable, with cocktails around €6 and a small can of beer around €3.50.
I see the value in the all-day format. A ferry trip to another island usually gives you transport but leaves you to arrange food, local movement, and beach time yourself. Here, the crew handles the route, lunch, timing, and return to Kos.
The trade-off is that you are sharing the boat with a large group. The maximum capacity is 135 people, and high-season sailings can feel full. If you want polished seating, quiet conversation, or plenty of room around the railings, this may not be the right boat.
For most people, the appeal is simple: you pay one modest fee, step aboard at Kos Port at 10 a.m., and spend roughly seven hours moving between islands and swimming spots.

Leaving Kos and settling into the Odyssey

The day begins at Kos Port, where the boat returns at the end of the cruise. The long first crossing gives you time to settle in, find your place, and take in the sea views before the first stop.
Arrive early if shade matters to you. Seating is not reserved, and the boat spends much of the day in the sun. A hat is useful, but secure it well because the wind can carry it away. I would also pack sunscreen, water for personal use, and some cash for drinks or snacks.
The atmosphere is more relaxed than a hard-party boat, but it is not silent. Music plays during the cruise, and the bar serves cocktails and other drinks. One useful detail from the experience is that the music can become loud, especially if a large group sets the tone for the boat.
The crew gets frequent praise for being friendly, helpful, and organized. Captain Giannis is singled out for making an effort to locate dolphins after receiving news of a sighting. That kind of flexibility adds character to the trip, although the exact route can depend on sea conditions and wildlife.
Vathi: entering Kalymnos through a natural fjord

The first stop is Vathi, a village on Kalymnos reached through a striking natural fjord. The approach is part of the pleasure. As the boat moves into the narrow inlet, the valley opens slowly, with gulfs and caves around you.
You have one hour ashore. That is enough for a short walk through the peaceful streets, a local sweet, or a fresh homemade orange juice. You can also look around the sponge warehouses, which connect the village to Kalymnos’s long sponge-diving tradition.
Vathi is not a place for a rushed checklist. Its value is the quiet change of pace after leaving the port. You are not being pushed through a major attraction with a guide and a timetable. Instead, you get a brief chance to walk, look, and enjoy the setting before returning to the boat.
Keep expectations realistic. One hour is not enough for a full visit to Kalymnos, and the stop is meant as a taste rather than a deep exploration. If you want museums, long walks, or a full meal in the village, you will need a separate trip.
Fish farms and the chance to see dolphins

After Vathi, the boat passes near fish farms on the way toward Plati. The fish attract wild dolphins, and the route offers a chance to see them jumping beside the boat.
This is one of the most memorable parts of the day when it happens. You are not watching a staged animal show. The dolphins are in open water, and the captain may adjust the route when a sighting is reported.
Still, treat dolphins as a bonus, not a promise. Wildlife follows its own schedule, and no boat trip can guarantee a sighting. Keep your camera ready, but do not spend the entire crossing staring at the horizon. The sea passage itself is part of the day.

Plati: clear water, a boat swim, and cocktails

Near Plati, the boat anchors close to shore and stops its engines. This is the main swimming break, with clear blue and turquoise water and a sandy bottom visible below.
The swimming setup is practical but not ideal for everyone. You can jump from the side of the boat, or descend by ladder. The jump is from a noticeable height, and the ladder is fairly vertical, so you should decide based on your comfort in open water. If neither option appeals to you, you can remain aboard and enjoy the stop without swimming.
The water is the star here. The boat’s position gives you a chance to swim around it rather than visit a developed beach. Bring swimwear, a towel, and sunscreen, and protect your phone if you plan to take pictures.
While the boat is stopped, happy hour begins. Cocktails are reported at about €6, and the bar also sells beer and other drinks. The pricing is a useful part of the value, since you do not need to wait until returning to Kos for refreshments.
The swim stop lasts about an hour. That sounds generous, but boarding, changing, and taking turns at the ladder can reduce the actual swimming time. If swimming is your main reason for booking, move quickly once the engines stop.
Greek BBQ lunch served onboard

Lunch is included and served on the boat. The standard plate has pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian option includes beans, dolmades, salad, tzatziki, and bread.
This is straightforward Greek food rather than a long restaurant meal. The advantage is convenience. You eat without giving up island time, and the crew serves a large group efficiently. Several meals are described as tasty and better than expected, while one practical assessment is that the food is basic but adequate.
I would keep that distinction in mind when comparing the price. You are not paying for a gourmet cruise. You are getting a filling meal that removes the need to buy lunch during a tightly timed day. Vegetarian guests should have a clear option, and the crew has handled that request well.
The bar remains available, but drinks are extra. Bottled water, soda, and alcoholic beverages are not included, so budget a little more if you expect to buy several drinks.
Pserimos, the quietest stop of the day

The final island stop is Pserimos, a small island with only about 15 families during winter. Summer brings more people, but the island still feels much less developed than Kos.
You get one hour to explore. The shallow sandy beach is the obvious choice for an easy swim, especially for families and anyone who prefers a gradual entry into the water. You can also follow local paths or sit at a café or taverna.
Pserimos is best approached as a short island pause, not a major sightseeing destination. There are no long lists of attractions to cover. The pleasure is sitting near the water, taking a brief walk, or enjoying a drink before the boat leaves.
Some people may find the stop too quiet, particularly if they expect shops, monuments, or a busy town. For me, that simplicity is useful after a full day at sea. You get a final hour to slow down before the return crossing.
What the long day feels like onboard

The full duration is about seven hours and 15 minutes, and the crossing time matters. You visit three places, but the schedule includes long stretches on the boat. The first and last journeys are especially lengthy, so choose this trip because you enjoy being at sea, not only because you want to step onto islands.
The boat has toilets and a bar, according to the experience details and firsthand comments. Seating is functional rather than luxurious. Some people find it uncomfortable after several hours, especially when the boat is full.
The atmosphere can vary. Music, cocktails, and a friendly crew create a holiday mood, but a loud group or nearby smokers can change your experience. There is no guarantee of a quiet corner, and shade may be limited.
Families can make this work. A four-year-old has been able to join in with the activities, and the setting is described as family-friendly. Couples and groups of friends will also find plenty to enjoy, especially if they like swimming, casual music, and a social boat ride.
Practical details that make the day easier
The meeting point is Kos Port, Kos 853 00, and the scheduled start is 10 a.m. The cruise ends back at the same meeting point. Confirmation is provided when you book, and service animals are allowed.
The tour is offered in English. Most people can participate, but the swim stop requires enough confidence to use a ladder or jump into the sea. If you do not want to enter the water, you can stay on the boat, though you should not expect a separate beach transfer.
Weather matters. If poor conditions cancel the cruise, you are offered another date or a full refund. You can also cancel for a full refund up to 24 hours before the start time. Changes or cancellations inside that window are not accepted.
The strongest preparation list is short:
- Arrive early if you want a better chance of finding shade.
- Bring sunscreen and secure your hat.
- Carry cash for onboard purchases.
- Pack swimwear and a towel.
- Expect basic seating and a full boat.
- Keep your camera ready near the fish farms, but do not count on dolphins.
Who should book this Kos boat cruise?
I would choose this trip if you want maximum scenery for a modest price and like the idea of combining swimming, island walks, lunch, and a casual bar in one day. It suits families, friend groups, and relaxed couples who do not need luxury seating or a silent deck.
The cruise is also a good fit if you have limited time on Kos. Instead of spending several days arranging separate island visits, you get brief introductions to Kalymnos, Plati, and Pserimos in one outing.
I would hesitate if you dislike crowds, loud music, sun exposure, or long boat crossings. You may also prefer another option if you want serious sightseeing on Kalymnos, since the Vathi visit is only one hour.
At $36.28, the package is hard to fault on value alone. The included lunch, three stops, swim break, and chance of dolphins give you a lot for the price. Just book it with the right expectations: this is an upbeat, social day cruise with basic comforts, not a private yacht charter.
