From the Port of Kos: Full Day Boat Cruise to 3 Islands

Sea days are hard to beat. This full-day cruise from Kos packs Kalymnos, Plati, and Pserimos into one relaxed outing, with swimming stops, a Greek buffet lunch, and a chance to spot dolphins near local fish farms. I especially like the mix of quiet island time and easy swimming from the boat. The crew, led by Captain Yanas, also earns steady praise for being cheerful, attentive, and helpful.

The main consideration is that this is a shared boat trip, not a private sailing. Seating can feel tight when the boat is full, and the sea may turn choppy. You should also bring cash for Pserimos, where some island businesses do not accept cards.

Key points at a glance

• A proper island-hopping day: You visit Kalymnos, Plati, and Pserimos, with time to walk around two island stops and swim in clear water.
• Vathi on Kalymnos is the scenic opener: The village sits beside a natural fjord framed by cliffs, caves, and small coves.
• Dolphins are a welcome possibility: The boat passes fish farms, where wild dolphins are sometimes seen jumping close to the boat.
• Lunch is included: Expect souvlaki, salad, tzatziki, and bread, with beans and dolmades available instead of meat.
• The atmosphere is relaxed: Soft music, affordable cocktails, and a friendly crew make this a calmer choice than a loud party boat.
• The price is strong for a full day: At $35 per person, you get the cruise, island stops, swimming, and lunch, while drinks cost extra.

What the Kos to three-island cruise is really like

You meet the blue Odyssey boat at the harbor of Kos, opposite the Port Police. Be on board by 9:30 for ticket checks. The listed duration is 450 minutes, or 7.5 hours, though the exact day can run a little shorter or longer depending on sea conditions and the time spent watching dolphins.

The first sailing takes about an hour. That gives you time to settle into the boat, find a place to sit, and enjoy the views across the Dodecanese. The mood is generally easygoing, with music at a moderate level rather than a nonstop party soundtrack. One person wished for more traditional Greek music, but another found the playlist a good fit and was relieved that it was not too loud.

The boat can get busy. Most people still find enough room for a comfortable day, but one account described six people sharing space intended for four. If you want a good position, board on time rather than strolling in at the last moment. The front can be exposed to spray when the sea is rough, so the best seat is not always the most forward one.

Vathi on Kalymnos: cliffs, caves, and a peaceful hour

The first stop is Vathi, a village on Kalymnos. The approach is the visual highlight of the outward journey, with a natural fjord, rugged cliffs, small gulfs, and caves. Have your camera ready as the boat enters the inlet.

You get free time to walk through the village and sample local specialties. The stop is scheduled for about an hour, although the time can change. On one outing, a longer dolphin stop reduced time at the first island to roughly 30 minutes. That is a fair trade if you see dolphins, but you should not expect a long, leisurely visit every time.

Vathi works best as a short taste of Kalymnos rather than a full island tour. You can stroll, look around, and get a sense of village life, but the schedule does not allow for a long hike or a detailed exploration. I like this approach because the day gives you three different settings instead of spending all afternoon in one place.

The bay also gives you a welcome break from open water. If you are sensitive to motion, the calmer setting may be easier than the longer sea crossings. Still, bring any medication you need. The crew has helped passengers with seasickness tablets, but it is better to plan ahead.

Lunch on board: simple Greek food that does the job

After Kalymnos, the boat serves a buffet lunch. The standard plate includes pork or chicken souvlaki, salad, tzatziki, and bread. The food is simple, filling, and suited to a long day in the sun. Several people especially liked the generous portions and freshly prepared meal.

The vegetarian choice replaces the meat with beans and dolmades. This is useful for vegetarians, and the crew has been praised for taking meal preferences in advance. The vegetarian food can also work for vegans if you skip the tzatziki, according to the information provided by a vegan couple.

Do not expect a restaurant meal with a long menu. One person would have preferred Greek salad instead of cabbage salad, so the side dishes may not match everyone’s idea of a perfect Greek lunch. Still, including a substantial meal at this price makes a real difference. You do not need to bring lunch or spend valuable island time searching for food.

Drinks are not included, but the onboard bar sells water, cocktails, and other refreshments. Cocktails were reported at around €6, and bottled water was available for €1 during happy hour. Those prices make it easier to enjoy a drink without feeling that every purchase is a penalty.

Dolphin watching near the fish farms

After lunch, the boat passes nearby fish farms. This is the best point in the day for dolphin spotting. The captain may slow down or make another turn if dolphins appear, giving you a better chance to see them from the boat.

Dolphins are never guaranteed, so treat them as a bonus rather than the main reason to book. On several outings, people saw groups of dolphins close to the boat, with one account describing at least eight. Others also reported flying fish. When the animals appear, the whole boat tends to shift its attention toward the water, which adds a shared sense of excitement to an otherwise calm cruise.

This section can also affect the schedule. If the captain spends extra time with dolphins, the first island stop may become shorter. I consider that a sensible adjustment, especially for anyone who values wildlife over a few extra minutes of souvenir shopping.

Plati: your best chance to swim from the boat

The next stop is Plati islet, reached after about 45 minutes of sailing from Kalymnos. Here the main activity is swimming in turquoise water around the boat. You may jump directly from the boat, so bring your swimsuit under your clothes and keep your towel handy.

This is not a beach afternoon. The attraction is the water itself and the freedom to swim around the anchored boat. Several people described this as one of their favorite parts of the day, especially in the summer heat. Families with children also found the swim stop a highlight, though children should be comfortable around open water and supervised closely.

Wind can change the plan. On one occasion, the boat could not dock at Plati, so the crew offered an extra bay swimming stop at Pserimos instead. That is worth remembering: the exact order or location of a swim may change for safety and sea conditions.

The boat’s happy hour adds a pleasant touch here. You can order a cocktail and listen to music while others swim. The result is more relaxed than organized water sports. You are free to take a swim, sit in the sun, or simply watch the sea.

Pserimos: a small island with time to wander

After roughly 20 minutes of sailing, the cruise reaches Pserimos. You get about an hour to explore at your own pace. Compared with the scenic inlet at Vathi and the open-water swimming at Plati, Pserimos gives the day a more traditional island-stop feel.

Use the hour for a slow walk, a look around the harbor area, or a drink if you find a place that suits you. The stop is not designed for a major sightseeing program. It is a chance to step off the boat, stretch your legs, and enjoy a small island at a slower pace.

Bring some cash. One useful tip from the trip information is that restaurants on the last island may not accept cards. That is a small detail, but it can save you from standing at a café with a beautiful view and no way to pay.

The return to Kos takes about 30 minutes after the final stop, though conditions at sea can affect timing. By then, most people have had enough sun, swimming, and fresh air to appreciate a quiet ride back.

Crew, music, and the mood on board

The crew is one of the strongest reasons to choose the Odyssey. Captain Yanas and the team are repeatedly described as friendly, attentive, and good-humored. They help with tickets, food arrangements, drinks, swimming, and general questions without making the day feel over-managed.

The tone is more relaxed cruise than party boat. Soft music plays during the sailing, and the captain provides information about the islands. One person wanted more old Greek music, but the sound level generally suits people who want conversation and sea views.

The boat is described as comfortable with plenty of space, though not always spacious when full. Conditions matter too. The front can become wet in rougher water, and choppy seas are possible. If you prefer a perfectly smooth ride, no open-water cruise can promise that. If you pack sensibly, the motion is easier to manage.

Price and value for a full day from Kos

At $35 per person, this is a strong-value outing. Your price covers the cruise to three islands, swimming stops, and lunch with meat and vegetarian options. For a full day on the water, that is considerably better value than paying separately for transport, meals, and several short boat rides.

You still need to budget for drinks, towels, and any purchases on the islands. Hotel transfer is not included, so you make your own way to the harbor. The meeting point is clear: look for the blue Odyssey boat opposite the Port Police.

The real value is the variety. You get dramatic scenery at Vathi, a swim from the boat at Plati, an island walk at Pserimos, lunch, and a chance to see dolphins. None of these parts is a full guided tour on its own, but together they make a satisfying day.

Who will enjoy this cruise most

I would choose this for anyone who wants an easy way to see more of the Dodecanese without organizing ferries or private boat hire. It suits couples, families, swimmers, and people who like a full schedule with plenty of downtime between stops.

It is also a good choice if you want a calmer alternative to a loud pirate-style boat trip. The music is present, but the day centers on scenery, food, swimming, and friendly service.

You may want another type of excursion if you dislike shared boats, need lots of personal space, or want a long, detailed visit on one island. The schedule gives you a taste of three places, not a deep visit to any one of them. Anyone with mobility concerns should also confirm suitability before booking. The activity information describes the boat as wheelchair accessible but also says it is not suitable for people with mobility impairments, so that point needs clarification.

What to bring for a better day

Pack a sun hat, swimwear, towel, and plenty of sunscreen. A light cover-up is useful between swimming and island walks, though it is not specifically required.

Keep your phone and camera protected from spray, especially if you sit near the front. Bring cash for Pserimos, and consider carrying seasickness medication if you are prone to motion sickness.

The boat sells drinks, but bringing water for the start of the day is still sensible. You will be outside for hours, and the sun can feel strong even when the breeze makes the air seem mild.

Should you book the Odyssey three-island cruise?

Book it if you want excellent value, clear water, a filling lunch, and three different island experiences in one day. The warm crew, affordable bar, and real chance of seeing dolphins add plenty to the basic route.

Skip it if you want a private boat, a quiet luxury experience, or long hours exploring one island. For most people staying in Kos, though, the Odyssey offers an enjoyable and practical day at sea. Just arrive early, accept that the schedule may shift with wind or dolphins, and bring cash, sunscreen, and a towel.
