Kos: 3-Island Cruise with Greek BBQ Lunch and Swimming

The best part of this Kos boat trip is the variety packed into one day. You visit Kalymnos for sponges and local products, swim in the clear water around Platy, and finish at the little beach of Pserimos. Between stops, the Santa Maria gives you cushioned sun decks, shade, tables, and a bar.

I like the Greek BBQ lunch served aboard, and I like the chance to spot dolphins during the cruise rather than spending the whole day tied to one beach. The drawback is that the boat typically fills to capacity, and one of the three island stops is mainly a swimming stop rather than a full island visit.

Key things to know before boarding

• Three very different stops: Kalymnos offers a port and local shopping, Platy is focused on swimming, and Pserimos gives you beach time and a short walk ashore.
• The Santa Maria is a large wooden boat: You get sun decks with cushions, a shaded area, tables, and a bar, but shade seats can go quickly.
• Dolphin watching is part of the route: The planned stop lasts about 20 minutes, though wildlife sightings can never be guaranteed.
• Lunch is included, drinks are not: Pack cash for the bar, souvenirs, honey, orange juice, and other local products.
• Arrive 30 minutes early: You must meet outside the Santa Maria and carry your passport or a copy for boarding.
• This suits active passengers best: Swimming, boat jumps, uneven shore areas, and limited mobility access make it unsuitable for pregnant women and people with mobility impairments.

A full day on the Aegean aboard Santa Maria

From the port of Kos, you board the 80-foot Santa Maria for a long day on the water. The boat is made for a social outing rather than a quiet sailing trip, with open sun decks, padded cushions, a shaded section, tables, and a bar.

That setup matters because seven to seven and a half hours is a long time to spend at sea. You can move between sun and shade, sit at a table for lunch, or stretch out while the boat crosses the Dodecanese waters. If you want a shaded seat, arrive early. One person found that sitting near the cabin meant staying in shade for much of the day, while another advised arriving early to claim the best protected spots.

The boat can reach capacity, so do not expect an intimate cruise. I would treat the full boat as part of the atmosphere: music, conversation, swimming, drinks, and an upbeat crew. If you prefer a calm, small-group sailing trip, this is not the right format.

The crew speaks English, German, Greek, and Italian. Ariel and Aria are among the staff members singled out for warm, helpful service, and the crew keeps the energy going with friendly attention and Greek dancing near the end of the day.

The first cruise from Kos to the island group

The opening cruise takes about 80 minutes. This is your first chance to settle in, find a seat, and watch Kos fade behind you as the boat heads toward the nearby Dodecanese islands.

The route is as much about being on the water as it is about reaching each stop. You will have time to work on your tan, sit beneath the shade, order a drink, and take in the blue sea from the deck. Sunscreen is essential, even if you plan to spend much of the morning under cover. Reflections from the water make the sun feel stronger than it may at the port.

The day has several stretches of cruising between stops. Bring a towel and something comfortable to sit on if you have a preference, though the boat provides cushioned areas. A light cover-up can also help after swimming, since the wind and boat speed may feel cooler than the beach.

Dolphin watching for about 20 minutes

The boat makes a planned stop for dolphin watching, lasting about 20 minutes. This is a pleasant break from the longer crossings, and the route gives you a chance to look for dolphins gathering near the boat.

Keep your expectations sensible. Dolphins are wild animals, so no sighting can be promised, but the cruise specifically allows time to watch for them. Stay on deck and scan the water rather than treating this as a formal wildlife tour with guaranteed encounters.

If you have children in your group, this can be one of the most exciting parts of the crossing. It also gives adults something to do between swimming and meals. Have your phone ready, but keep watching instead of staring at the screen. A dolphin appears and disappears quickly.

Kalymnos: a one-hour taste of sponge island life

Kalymnos is the most cultural stop of the day. The boat allows about an hour near the port, with time to walk around the small town of Vathy, browse local shops, and see the island’s traditional sponge trade up close.

Greek sponges are the signature purchase here. At local stores, you can touch and compare the natural sponges, then decide if one makes a useful souvenir. This stop also gives you a chance to shop for local honey and fresh orange juice, along with other products that are difficult to find in ordinary souvenir shops.

The hour is enough for a short walk and a quick purchase, not a full exploration of Kalymnos. You will need to watch the time and return to the boat promptly. If you want a sit-down meal on shore, one hour leaves little room for a slow lunch. One person used the stop to eat souvlaki at a small restaurant by the port, but the included meal is served later aboard Santa Maria.

Kalymnos gives the day some local character. You are not only stopping at swimming spots; you are also seeing a working island port and getting a small look at products tied to local life. The visit is brief, so think of it as an introduction rather than a full island tour.

The Greek BBQ lunch on board

Lunch is included and served aboard the boat. The Greek BBQ is one of the strongest reasons this trip offers good value at $28.23 per person, since you receive a full day at sea, several stops, swimming time, and a meal without paying for a separate restaurant lunch.

Drinks are not included. The bar is available, but you will need extra cash for water, soft drinks, cocktails, or other purchases. The bar helps make the boat feel like a floating lunch stop, but keep your spending in mind if you are traveling with a family or plan to order several drinks.

The timing also works well. You can explore Kalymnos without needing to organize lunch there, then eat while continuing along the route. Some people may prefer choosing their own meal in a port, but the onboard BBQ keeps the schedule simple and leaves more time for the islands and swimming stops.

The dining area has tables, though seating can be in demand on a full boat. Find your preferred spot early, especially if you want shade during lunch.

Platy Island: clear water and a swimming stop

Platy is the day’s main water stop. The boat allows about 40 minutes here for swimming, and the clear water is the main attraction.

You may also have the chance to jump from the rocks or from the upper deck of the boat. The small cliff jump near Platy adds a little thrill, but it is optional. Only jump if you are comfortable, follow the crew’s instructions, and check the water before entering. You can enjoy the stop just as well from the ladder or by floating beside the boat.

This is not a long beach visit. The boat stops for swimming rather than taking you ashore for a walk, cafés, or shopping. That distinction matters. If your idea of an island tour means stepping onto each island, Platy may feel like a technical stop. If your ideal day includes warm water, a sun deck, and a quick jump from the boat, it may be one of your favorite parts.

Bring your towel where you can reach it easily. After swimming, you may want to dry off before lunch or the next crossing. Water shoes are not listed as required, but you should take care around rocks and ladders.

Pserimos: beach time, cafés, and small shops

The final island stop is Pserimos, where you get about 40 minutes for free time, shopping, sightseeing, and a walk. Compared with Platy, this is a proper chance to step ashore and enjoy a beach setting.

Pserimos is a good place to slow down after the active swimming stop. You can walk along the beach, stop at a café, or browse small vendors for souvenirs and local goods. The visit is short, so you will not have time for a long walk or an extended beach stay, but it adds a different mood to the day.

I like the way the stops balance one another. Kalymnos gives you products and port life. Platy gives you open-water swimming. Pserimos gives you a beach and a few places to wander. None of the stops offers a full island day, but together they create a broad sample of the area.

Keep cash with you at Pserimos. Shopping is not included, and the tour specifically recommends bringing cash for island purchases. You should also keep track of the departure time. A small island stop can feel relaxed, but the boat cannot wait for a late return.

The long ride back to Kos

After Pserimos, the boat spends about an hour and a half cruising back toward Kos. This is the longest return stretch, so it is a good time to claim a comfortable seat, order a drink, and let the day settle.

You may see more sea views, listen to music, or join the onboard atmosphere. Greek dancing near the end of the trip has been part of the fun, and the crew’s friendly style helps keep the return from feeling like a simple transfer.

The return crossing is also when the full-day nature of the experience becomes clear. You have been in the sun, swimming, walking, eating, and moving between islands for most of the day. Pack sunscreen and use it again after swimming. A little planning makes the final crossing much easier.

Is $28.23 good value for a Kos boat tour?

At $28.23 per person, this is a low-cost way to spend nearly a full day on the water. The price includes the cruise, three island stops, swimming opportunities, and Greek BBQ lunch. You still pay for drinks, souvenirs, and local products, but those are easy costs to control.

The value is strongest if you want variety. A separate boat ride, island port visit, swimming stop, lunch, and dolphin watch would usually take more planning. Here, the route and meals are arranged for you.

The price comes with tradeoffs. The boat can be full, the island visits are short, and the schedule is fixed. Platy is mainly a water stop, and Pserimos is only about 40 minutes. You are paying for a lively full-day group cruise, not a private charter or a slow island expedition.

For families, couples, and friends who want an active day without a high price, the cost is attractive. For anyone wanting quiet, personal space, or long hours on one beach, a smaller boat or a single-island excursion may be a better use of money.

What to bring and who should book

Pack swimwear, a towel, sunscreen, cash, and your passport or a copy of your passport. You need the passport document for boarding, even though the tour begins and ends at the port of Kos.

You should arrive 30 minutes before departure and meet outside the Santa Maria. Transfers to the harbor are not included, so you must arrange your own way to the meeting point.

This trip fits you best if you:

• Enjoy swimming and spending long hours outdoors
• Like a social boat with music, food, and a bar
• Want to see several nearby islands in one day
• Are happy with short shore visits
• Like local shopping, Greek food, and informal entertainment

It is not suitable for pregnant women or people with mobility impairments. The boat, swimming stops, ladders, shore access, and island walking all make this a more active outing.

Should you book this three-island cruise?

Book it if you want a cheerful, good-value day at sea with swimming, a Greek lunch, local shopping, and the chance to see dolphins. The crew, especially Ariel and Aria, adds a personal touch, and the mix of Kalymnos, Platy, and Pserimos keeps the day from feeling repetitive.

Skip it if you need a quiet boat, lots of personal space, or a full day on each island. You should also think twice if you dislike fixed schedules or do not swim. For most active visitors staying in Kos, though, this is an easy way to sample the surrounding islands without spending much.
