Full Day 3-Island Boat Cruise from Port of Kos

Three islands, one easy day at sea. This cruise packs Kalymnos, Plati, and Pserimos into about seven hours and 15 minutes, making it a useful choice if you want a taste of the nearby islands without arranging ferries or private boats. I especially like the chance to enter Vathi’s dramatic fjord and the stop for swimming in clear water near Plati. The included Greek lunch also helps make the $36.28 price feel unusually fair.

The main catch is comfort. The boat can carry up to 135 people, and seating may feel tight during the long stretches between stops. You should arrive early if shade matters, bring sunscreen, and understand that the swimming stop involves either jumping from the boat or using a ladder.

Five things to know before you book

• Vathi is the scenic first stop: You enter a natural fjord on Kalymnos before getting an hour to walk around the village.
• Dolphins are a possible highlight: The boat passes fish farms near Plati, where dolphins are often spotted feeding.
• Plati is mainly a swim stop: You stay near the boat, with clear water, a sandy bottom, and drinks available onboard.
• Pserimos offers a quiet island hour: Swim from its shallow beach, follow a path, or sit at a small cafeteria or taverna.
• Lunch is included: Expect pork or chicken souvlaki, salad, tzatziki, and bread, with a vegetarian plate available.
• Shade and cash matter: Much of the day is spent in the sun, and onboard drinks and snacks are paid for separately.

From Kos Port to Kalymnos at 10 a.m.

The boat leaves the port of Kos at 10 a.m. and returns to the same meeting point. That simple arrangement is useful: you do not need to coordinate a taxi, ferry connection, or island transfer. Confirmation arrives at booking, and the tour is offered in English.

The first sailing stretch is part of the day’s rhythm. You are on the water for a while before reaching the first stop, so this is not a quick hop between islands. Bring sunscreen, water, and a hat that can be secured. One hat reportedly went flying, which is no surprise once the boat gets moving.

The boat has a bar, toilets, music, and places to sit, but this is a working excursion boat rather than a luxury yacht. Some seating can feel hard after several hours. If you prefer quiet, roomy seating and plenty of personal space, a smaller private cruise may suit you better.

The music creates an easygoing holiday mood, though the volume may be too high for some people. The atmosphere is generally family-friendly, but a large group can change the tone and make the boat feel louder and more crowded.

Entering Vathi’s fjord on Kalymnos

The first stop is Vathi, a village on Kalymnos reached through a striking natural fjord. As the boat moves into the inlet, the valley opens gradually, with gulfs and caves around you. Keep your camera ready during the approach, since the entry itself is one of the prettiest parts of the day.

You get about an hour ashore. That is enough time to walk the peaceful streets, try local sweets, and order homemade orange juice. Vathi also has a connection to Kalymnos’s sponge trade, and the local sponge warehouses offer a glimpse into the island’s working past.

Do not expect a full historical tour or a long village visit. An hour passes quickly, especially if you want a drink, photographs, a walk, and time to look around. The value here is the setting and the change of pace, not a packed list of monuments.

I would use this stop to wander rather than rush from one shop to another. The fjord is the main attraction, and the village feels more pleasant when you allow time to notice the water, the surrounding rock, and the local businesses.

Dolphin spotting near Plati

After Vathi, the boat heads toward Plati islet and passes nearby fish farms. Fish scraps attract wild dolphins, and the captain may adjust the route if dolphins have been sighted in the area. Captain Giannis has been praised for making an extra effort to give people a chance to see them.

Dolphin sightings are never guaranteed, so treat them as a bonus rather than a promised part of the schedule. If you do see them, the moment can be brief. Keep watching the water, especially near the fish farms, and do not put your camera away too soon.

This part of the route adds something special to an otherwise straightforward island cruise. Seeing dolphins in open water feels very different from seeing them in a show. The boat’s crew can point out activity, but you will need a little patience and luck.

Swimming from the boat near Plati

The boat anchors near Plati, close enough to the islet for a clear view of its shore. Once the engines stop, you can swim around the boat in water described as exceptionally clear, with the sandy bottom visible through blue and turquoise water.

This is one of the strongest parts of the trip if you enjoy swimming. It is also the section that requires the most practical awareness. The entry options include jumping from the side of the boat, from a height, or descending by a ladder. That may not work for anyone who is nervous in open water or uncomfortable climbing down from a boat.

There is no suggestion that this is a guided snorkeling session, so bring realistic expectations. The appeal is the clean water and freedom to swim around the anchored boat. If you prefer a gentle beach entry, the later stop at Pserimos is likely more comfortable.

While the boat is anchored, happy hour begins. Cocktails are available for about €6, and a small can of beer has been reported at around €3.50. Alcohol, soda, and bottled water are not included in the ticket price. Prices are reasonable for a boat bar, but a family group can still spend more than expected if everyone orders several drinks.

Greek lunch served onboard

Lunch is a barbecue served on the boat. The standard plate includes pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian option includes beans and dolmades, along with salad, tzatziki, and bread.

The meal is simple, but it gives you a proper break without losing time at another port. Several accounts describe the food as tasty, fresh, or better than expected. It is not restaurant dining, and one criticism is that the tour does not stop somewhere where you can choose your own meal.

For the price, I think the included lunch is a real advantage. A seven-hour boat day can become expensive once you add food, drinks, and beach stops. Here, the main meal is covered, and the crew handles serving a large group efficiently.

Tell the operator about dietary needs when booking or before boarding if possible. The available vegetarian plate has been handled well, but the information provided does not list other special diets.

A quiet hour on Pserimos

Pserimos is the final stop. Only about 15 families live there during winter, while summer brings more activity. The island is less about sightseeing in the formal sense and more about enjoying a small beach community for an hour.

You can swim from the shallow sandy beach, look for a path to follow, or sit at a local cafeteria or taverna. This stop works well after the more active swimming session at Plati because you can choose your own pace.

The one-hour limit is both useful and restrictive. It gives you enough time to swim or have a drink, but not enough for a long walk or a detailed visit. Some people may find that Pserimos has little to see beyond the beach and a few local places to eat.

That is worth knowing before you book. This is a day of sea views, short island visits, and time outdoors. It is not an archaeological tour or a deep exploration of Kalymnos and Pserimos.

Is the $36.28 price good value?

Yes, for the right kind of day. The ticket includes transport from Kos and back, three stops, a swimming break, possible dolphin spotting, onboard entertainment, and lunch. Booking ferries, meals, and separate excursions to cover the same area would take more planning and could cost more.

The low price also explains some compromises. The boat may be full, seats are not especially plush, and time ashore is limited. You are buying access and convenience, not privacy.

Drink prices are fairly modest for a boat trip, with cocktails around €6 and beer around €3.50 in the supplied examples. Bring some cash for drinks, snacks, or purchases on the islands. Bottled water is extra, so carrying your own bottle of sunscreen is not enough, you should also plan your water supply.

The tour earns a 4.8 rating from 1,133 ratings, with 96 percent recommending it. Those numbers point to strong value, but they should not hide the fact that a few people found the boat packed, the music loud, and the island stops too limited.

Who will enjoy this cruise most?

I would choose this trip if you want an easy way to see the waters around Kos and prefer a social boat atmosphere. It suits couples, families, and groups who want a full day with swimming, music, simple food, and a few drinks.

It also works well for families with young children. A four-year-old has been able to take part in the day’s activities, and the boat has toilets and food onboard. Still, watch children closely around the swimming area, particularly because the entry is from the boat rather than a gently sloping beach at Plati.

You will probably enjoy it if you like:

• Short visits to several places rather than one long island stay
• Swimming in clear open water
• A casual Greek barbecue
• Music and an informal bar
• The chance to see dolphins
• A fixed schedule with transport handled for you

I would think twice if you need quiet, spacious seating, a calm swimming entry, or lots of time ashore. Smokers may also affect your comfort, since one account describes being surrounded by smoke on the boat. The group size can reach 135, so high-season departures may feel especially full.

Practical tips for a better day

Arrive early. Seating is not reserved, and early arrival gives you a better chance of finding shade. This matters because much of the sailing is in direct sun.

Use plenty of sunscreen and reapply it during the day. A hat should be tied to a bag or secured to the boat. The wind can take it quickly.

Bring swimwear, a towel, and a small amount of cash. You can buy alcoholic drinks, soda, bottled water, and snacks onboard, but these are not included.

Pay attention when the crew announces departure times. Each island stop lasts about an hour, and the boat cannot wait for late returns. The crew is generally friendly and keeps people informed about the route and how long remains at each stop.

If you want to swim at Plati, be honest about your comfort level. You can use the ladder if that feels manageable, but there is no beach-style entrance at the anchored boat. Pserimos offers the easier sandy beach option.

The tour requires good weather and a minimum number of participants. If poor weather or low numbers cancel the trip, you can choose another date or receive a full refund. You can cancel for a full refund up to 24 hours before the 10 a.m. start time. Service animals are allowed, and the tour is near public transportation.

Should you book the Odyssey Boat Cruise?

I would book it for a good-value day on the water, especially if dolphins, swimming, and a relaxed Greek lunch sound more appealing than museums or long island walks. The crew, including Captain Giannis, receives especially warm praise, and the combination of clear water, small islands, and included food is hard to match at this price.

I would skip it if you dislike crowds or want a quiet, polished boat. The seating is basic, the music can be loud, and the stops are brief. Go early, claim some shade, carry cash and sunscreen, and treat the dolphins as a lucky extra rather than the main reason to go. With those expectations, this is a smart way to spend a full day beyond Kos.
