Full Day 3-Island Boat Cruise from Port of Kos

The best part of this cruise is the mix of three island stops and open-water sailing in one easy day. You enter Vathi’s fjord on Kalymnos, swim in clear water near Plati, and finish on quiet Pserimos, with a Greek barbecue served aboard the boat.

I like the generous free time at each stop and the friendly crew, including Captain Giannis, who has been praised for steering toward dolphin sightings when news comes in. The price is another strong point. The trade-off is a full boat, basic seating, and long stretches in the sun.

Key points at a glance

• Vathi’s fjord: Enter a dramatic natural inlet on Kalymnos, then walk the peaceful village, sample orange juice, or look at old sponge warehouses.
• Wild dolphins near the fish farms: The boat may spot dolphins attracted by fish farms, though sightings can never be guaranteed.
• Plati swimming stop: Swim from the anchored boat in clear blue and turquoise water, with a ladder or a jump from the side.
• One hour on Pserimos: Choose between the shallow sandy beach, small paths, or a local cafeteria and taverna.
• Lunch included: Expect pork or chicken souvlaki, salad, tzatziki, and bread, with a vegetarian plate available.
• Good value with a lively feel: Drinks cost extra, music plays onboard, and the maximum group size is 135 people.

A full Greek island day for $36.28

At about $36.28 per person, this is an unusually inexpensive way to put several Aegean stops into one day. The fare includes the boat ride, three scheduled locations, free time ashore, and lunch. You pay extra for water, soda, beer, cocktails, and other drinks, but onboard prices are described as reasonable, with cocktails around €6 and a small can of beer around €3.50.

The value is strongest if you want variety without arranging ferries, taxis, and beach transfers yourself. You can sit back while the crew handles the route, then step off the boat when the group reaches shore.

This is not a luxury yacht outing. Seating can feel hard and crowded during a seven-hour-plus day, and the boat may carry up to 135 people. I would think of it as a friendly, traditional excursion boat with a bar, music, and a relaxed party atmosphere, rather than a quiet private cruise.

The boat leaves the Port of Kos at 10:00 a.m. and returns to the same meeting point. The total duration is about seven hours and 15 minutes, so plan for most of your daylight hours to be at sea.

Entering Vathi through Kalymnos’s natural fjord

The first stop is Vathi, a village on Kalymnos. The boat enters a natural fjord, and the valley opens gradually around you. This approach is one of the most scenic parts of the day because the surrounding gulfs and caves appear as the boat moves farther in.

You have about one hour ashore. That is enough for a short walk through the quiet streets, but not enough for a long village visit or a broad tour of Kalymnos. Use the time with a plan rather than wandering too far from the waterfront.

Vathi offers small, local details that make the stop worthwhile. You can try traditional sweets, order homemade orange juice, and see sponge warehouses tied to the island’s long connection with sponge fishing. The warehouses give the place a sense of work and history without requiring a formal museum visit.

I would bring a camera for the fjord entrance and keep some cash handy for drinks, sweets, or a café stop. The stop is brief, so listen carefully when the crew explains the return time. Missing the boarding time is not a good way to extend your visit.

Dolphins, fish farms, and the Plati swimming stop

After Vathi, the boat heads toward Plati islet and passes nearby fish farms. Fish in the farms can attract wild dolphins, and the crew may slow down or adjust the route when dolphins are reported in the area. Several people have described dolphin sightings as the day’s highlight, but you should treat them as a lucky bonus, not a promised part of the schedule.

Seeing dolphins in open water is very different from watching a staged show. You may see them surface briefly, jump, or disappear before the boat reaches the right position. Keep your phone or camera ready, but do not spend the whole crossing staring through a screen.

The boat then anchors near Plati for a swim. The water is described as exceptionally clear, with the sandy bottom visible through blue and turquoise water. You get about an hour at this stop, although that hour also includes the time needed for people to enter and leave the water.

You can jump from the boat’s side or use a ladder. The jump is from a height, and the ladder descends vertically, so this stop may not suit anyone who feels unsure in open water. There is no suggestion of a gently sloping beach here. If you prefer an easy entry, check the ladder before committing.

While the boat is anchored, the bar opens for what is called happy hour. Cocktails are available for about €6, and beer and other drinks can be bought onboard. Some drinks are reported to be strong, so pace yourself if you plan to swim.

This is also where the cruise can feel most social. Music plays, people gather around the bar, and the mood may shift from sightseeing to a cheerful boat party. That can be fun for families and groups, but the music has been too loud for some people. If you want a quieter swim, do it early in the stop before the deck fills with people and music.

Pserimos, a small island with one hour to spare

The final stop is Pserimos, a small island with only about 15 families living there during winter. Summer brings more activity, but it remains a simple place rather than a developed resort.

You have one hour to explore. The shallow sandy beach is the easiest choice, especially for children or anyone who wants a straightforward swim. You can also follow small paths, sit at a local cafeteria, or order something at a taverna.

Do not expect a long sightseeing program on Pserimos. Its appeal is the slow pace, the beach, and the chance to step off a boat into a small island community. If you want churches, museums, extensive shopping, or a packed list of monuments, this is not that kind of stop.

The short visit works well as the last shore break because you can choose your own speed. Swim, have a drink, or sit in the shade and watch the boat from shore. Just remember that one hour passes quickly, particularly if you are ordering food or waiting for a table.

What lunch is like on the boat

Lunch is a simple Greek barbecue rather than a restaurant meal. The standard plate includes pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian option includes beans, dolmades, salad, tzatziki, and bread.

The meal has been described as basic but adequate, while others found it tasty and better than expected. That range makes sense: this is food prepared for a large group on a moving boat, not a leisurely taverna lunch. Still, it adds real value to the fare and saves you from having to find food during the short island stops.

Vegetarian catering is available, but tell the operator when booking or boarding if possible so the crew can prepare the right plate. The provided information does not list other dietary arrangements, so anyone with serious allergies should ask before departure.

Water, soda, and alcoholic drinks are not included. Bottled water is available to purchase. I would carry sunscreen and some cash, then buy drinks as needed rather than counting on the lunch service to cover everything.

Seating, sun, music, and the practical side

Arrive early if shade matters to you. Much of the journey is exposed to the sun, and seating is not described as reserved. Once the boat fills, moving into a shaded place may be difficult, especially if people settle into spots for the whole trip.

Take sunscreen, a hat with a strap, and perhaps a light cover-up. A hat can blow away while the boat is moving. The sun may be pleasant during the morning but tiring by the return crossing.

Seating is one of the main compromises. Some people find it uncomfortable for the number of hours onboard, particularly compared with newer or more expensive boats. The benefit is that the boat feels less formal and more like a classic group excursion.

Music plays through much of the day. Many people enjoy the atmosphere, and the cruise is described as family-friendly, including for a four-year-old. If you want silence, reading time, or a peaceful sail, bring realistic expectations. A large group can also make the deck loud, especially when drinks and music are flowing.

The boat has bar facilities and clean toilets, both useful on a full-day sailing. Service animals are allowed, the meeting point is near public transport, and most people can take part. The information does not specify detailed access arrangements for the boat, ladder, or shore landings, so ask the provider if you need step-free access or have mobility concerns.

Who will enjoy this Kos cruise most

I would recommend this trip to you if you want to see more of the islands around Kos without spending several days changing hotels or booking separate boats. It suits couples, families, and groups who enjoy a social day with swimming, music, drinks, and short walks.

It is also a good choice if you want a low-cost day on the water. The included barbecue, three scheduled locations, and chance of seeing dolphins make the fare easy to justify, even if you buy a few drinks.

Families should find plenty to do, especially at the shallow beach on Pserimos. Keep a close eye on young children at the Plati stop, since swimming is from the boat rather than from a normal beach.

I would be more cautious if you dislike crowds, loud music, smoking around you, or firm seating. The boat can feel packed in high season. You may also find the island visits too short if your main aim is a serious exploration of Kalymnos or Pserimos.

Booking, weather, and cancellation details

Confirmation is provided when you book. The activity starts and finishes at the Port of Kos, with departure at 10:00 a.m. It is offered in English and uses a mobile ticket.

You can cancel up to 24 hours before the start time for a full refund. Changes or cancellations made less than 24 hours before departure are not accepted for a refund. The activity depends on good weather. If poor weather cancels the cruise, you are offered another date or a full refund.

A minimum number of participants is required. If that number is not reached, you are offered another date or experience, or a full refund.

The group limit is 135 people. That is large enough for a busy deck, particularly during the summer, so early arrival is useful if you care about shade or a preferred seat.

Should you book the Odyssey Boat Cruise?

Book it if you want an affordable, easygoing island day with clear swimming water, a barbecue lunch, music, and a real chance of seeing dolphins. The combination of Vathi’s fjord, the Plati swim, and Pserimos’s sandy beach gives the day enough variety to keep it moving.

Skip it if you expect a quiet luxury cruise, long visits ashore, or a carefully guided cultural tour. The seating is plain, the boat can be crowded, and the stops are short.

For most people comparing boat trips from Kos, I would put this near the top of the budget-friendly choices. Arrive early, take sunscreen, bring cash, secure your hat, and treat the dolphins as a bonus. With those points in mind, the cruise offers a lot of Aegean scenery and swimming for the price.
