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

The best part of this cruise is the mix: you get three island stops, several chances to swim, a Greek lunch, and a good stretch of open water without paying for a luxury yacht. I like the peaceful hour in Vathi and the chance to spot dolphins near the fish farms. I also like that the crew keeps the mood friendly and relaxed rather than turning the boat into a loud party.

The main thing to consider is time. At 450 minutes, this is a full day on the water, and the boat can feel busy when everyone wants the best seats. Wind may also change the swimming stops, and the short island visits are for a taste, not a full exploration.

Key points to know before booking

• Vathi on Kalymnos: Spend about an hour around a natural fjord, with cliffs, caves, and a quiet village to explore.
• Swimming at Plati: Jump from the boat into clear turquoise water, though wind can sometimes change the plan.
• Dolphin spotting: The route passes fish farms where wild dolphins are sometimes seen near the boat.
• Lunch included: Expect souvlaki, salad, tzatziki, and bread, with beans and dolmades for vegetarians.
• Affordable onboard drinks: Cocktails are around €6, and water has been available for about €1 during happy hour.
• Simple port meeting point: Find the blue Odyssey boat opposite the Port Police and board by 9:30.

Three islands and a full day at sea

This is a classic Kos day cruise, but it has more substance than a quick boat ride around the harbor. You leave Kos and spend the day among the nearby Dodecanese islands, with time for a village visit, swimming, lunch, and a second island stop.

The advertised duration is 450 minutes, or seven and a half hours. Actual timing can vary because of wind, sea conditions, and dolphin spotting. One day may include extra time looking for dolphins, while another may require a change to the planned swimming stop.

I see the value in this format. You do not need to arrange ferries, find separate beaches, or work out island transport. The crew handles the route, food, and schedule while you sit back with music and sea views.

Still, this is not a private sailing trip. You share the boat with other people, and the seats can feel tight when the boat is full. Arrive early if you want a better choice of seating, shade, or a place near the rail.

Meeting the Odyssey at Kos Harbour

The meeting point is easy to identify once you know what to look for. Go to the harbor of Kos and find the blue boat named Odyssey, opposite the Port Police. You need to be onboard by 9:30 for ticket checks.

Hotel pickup is not included, so allow time to reach the harbor yourself. Bring your booking details, a hat, sunscreen, swimwear, and a towel. Towels are not provided.

The English-speaking captain and crew give information during the route and help passengers throughout the day. The crew has earned especially strong praise for being attentive and good-humored. That matters on a boat trip, where small things such as helping with boarding, finding a seat, or answering questions can shape the whole day.

The boat is described as wheelchair accessible, but the activity is also marked as unsuitable for people with mobility impairments. Those two details do not fully match, so you should confirm your own access needs before booking. Swimming from the boat and moving between the vessel and island docks may require good mobility.

Kalymnos and the fjord at Vathi

After roughly an hour of sailing, the boat reaches Vathi on Kalymnos. This is the most scenic village stop, with a natural fjord framed by rugged cliffs, coves, and caves.

You have about an hour here. That is enough to walk through the peaceful streets, take photographs, and try a local specialty, but not enough for a long village visit or a serious exploration of Kalymnos. Think of Vathi as a compact introduction to the island rather than a full-day visit.

The arrival is part of the attraction. You see the waterway open into the village and get a sense of how the island’s rocky coast shapes daily life. The setting feels more local and quiet than the larger resort areas of Kos.

Wear shoes suitable for walking and keep your expectations sensible. The stop is short, so you will need to choose between wandering, sitting for a drink, and taking photographs. If you want to cover every lane or spend time at a restaurant, the schedule will feel restrictive.

Lunch with souvlaki, salad, and vegetarian choices

After Vathi, you return to the boat for lunch. The meal includes pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian plate replaces the meat with beans and dolmades.

This is straightforward Greek boat food, not a formal restaurant meal. That is exactly what works here. You can eat onboard without losing time searching for food, and the meal is filling enough to carry you through the swimming stops and return voyage.

Vegetarians should make their preference clear to the crew before lunch. The vegetarian option has been described as suitable for vegans if the tzatziki is left out, but you should still confirm the ingredients directly with the crew if you have a strict dietary requirement.

The food has generally been one of the strongest parts of the day. Portions can be generous, and the meal arrives at a useful point in the schedule, after the first island and before the afternoon swimming. A small weakness is that the salad may be more like cabbage salad than the classic Greek salad some people expect.

Dolphin spotting near the fish farms

After lunch, the boat passes nearby fish farms. This is the best part of the route for looking for wild dolphins.

Dolphins are not guaranteed, and the captain cannot control where they appear. But several excursions have seen dolphins close to the boat, sometimes in groups. The captain may make an extra turn if dolphins are spotted, which can shorten or adjust the timing at another stop.

Keep your camera ready, but do not spend the whole cruise staring through a phone screen. Dolphin sightings happen quickly, and you may see only a fin, a jump, or a few animals moving beside the boat. The possibility adds a welcome sense of anticipation to an otherwise relaxed sailing stretch.

You may also spot flying fish, depending on conditions. The open water between the islands gives you a better chance to watch marine life than a short harbor cruise.

Plati islet and the main swim stop

Plati islet is the point for swimming from the boat. The water is clear and turquoise, and you can jump in and swim around the vessel rather than walking onto a conventional beach.

This stop is the day’s most active moment. You need to be comfortable entering the sea from the boat and climbing back aboard. Bring your own towel, and keep sunscreen nearby because the sun can feel strong after swimming.

The crew may play soft music while people swim or relax on deck. The atmosphere is usually easygoing, with cocktails available from the bar. The music is not always traditionally Greek, so do not book this expecting a folk-music program. The selection may be contemporary or mixed, and the volume can vary.

Wind is an important factor. On one occasion, the boat could not dock at Plati because of the conditions, and the crew added another swimming stop near Pserimos instead. That is a sensible adjustment, but it means you should view the exact route as flexible.

Pserimos and the final island hour

Pserimos is the last island stop. You have around an hour to explore at your own pace before the return to Kos.

This is a useful contrast with the boat-based swimming at Plati. You can walk around, look at the small settlement, and see a quieter side of island life. The stop is still brief, so it works best if you keep your plans simple.

Take some cash with you. Card payment may not be accepted at restaurants on the island, and the information supplied for the cruise specifically warns about this. You can use the hour for a short walk, a drink, or a quick look around, but do not count on a long meal and extensive shopping.

After Pserimos, the boat sails back toward Kos. The return takes roughly 30 minutes in the basic schedule, though the complete day can run longer or shorter depending on the sea and any changes made along the way.

Drinks, cocktails, and onboard comfort

Drinks are not included, but you can buy them onboard. Cocktails have been available for about €6, and bottled water has been offered for around €1 during happy hour. Prices are reasonable for a boat excursion, though you should carry some cash unless the crew confirms card payment.

The onboard bar adds to the social side of the trip. You can order a drink after swimming, sit with the group, and listen to music as the islands pass by. The atmosphere is more relaxed cruise than high-energy party boat.

Seating is one area where expectations matter. The boat has enough room for a comfortable day, but popular areas fill quickly. Some passengers have found the seating crowded, particularly when several people share space intended for fewer passengers.

The front of the boat can be a good place for views, but it may be exposed to spray in choppy conditions. If you want a dry ride, choose a more sheltered spot. If you are prone to seasickness, sit lower and closer to the middle of the boat, and ask the crew for help if needed. Crew members have assisted passengers with seasickness medicine, though you should not rely on this being available.

Is $35 good value?

At about $35 per person, this is strong value if you want a full day of swimming and island scenery. The price includes the cruise to three islands, swim stops, and lunch with meat and vegetarian options.

You would pay separately for drinks, and there is no hotel transfer. Even so, the cost covers several things that can quickly add up on an independent island day: transport by sea, food, local guidance, and access to multiple stops.

The value is best for people who want variety. In one day, you see a fjord village, pass fish farms, search for dolphins, swim from the boat, and visit Pserimos. The tradeoff is depth. You will not see every part of Kalymnos or Pserimos, and the island visits are timed introductions.

Prices and currency can change by season or booking date, so check the current amount before paying. The activity also offers free cancellation up to 24 hours before departure and a reserve-now, pay-later option, which is useful when your Kos plans may shift.

Who will enjoy this cruise most?

I would choose this for families, couples, and anyone who wants a simple day on the water without arranging several separate activities. Children who are confident in the sea should especially enjoy jumping from the boat, though you need to bring sun protection and keep an eye on them during swimming.

It also suits people who prefer a friendly, organized outing to a loud party cruise. The music is present, but the overall tone is described as calm and comfortable. The crew, including Yanni or Yanas, has been particularly attentive and good with families.

Vegetarians have a workable meal option, and the crew can help arrange it onboard. Vegans should ask about the meal ingredients and skip tzatziki if needed.

I would not choose this if you want a private boat, long walks on each island, a luxury meal, or a fixed route unaffected by weather. It is also a poor fit if you dislike a full day at sea or have difficulty boarding, moving around the boat, or entering the water.

What to pack for the Odyssey

Keep your day bag simple. Bring:

• Swimwear and a towel
• A sun hat and plenty of sunscreen
• Cash for Pserimos and onboard purchases
• Comfortable footwear for the island walks
• A waterproof pouch for valuables
• Motion-sickness medication if you normally need it

The sun is strong on the water, even when a breeze makes the air feel cool. Reapply sunscreen after swimming, and do not assume the boat will provide shade wherever you want to sit.

Should you book this Kos island cruise?

Book it if you want good value, clear swimming water, three island settings, and an easy Greek lunch in one day. The strongest reasons are the fjord at Vathi, the possibility of close dolphin sightings, the friendly crew, and the generous mix of included activities.

Skip it if your ideal day means quiet private sailing, long time in one village, or complete control over the route. For most people who want to see more of the Dodecanese without spending much, the Odyssey offers a satisfying and practical day out. Arrive early, bring cash and a towel, and treat the timetable as flexible when wind or dolphins change the plan.
