Shared Mykonos Sail Cruise to Delos and Rhenia Islands

Ancient Delos and the clear waters around Rhenia give this Mykonos boat trip a fine balance: you get a serious dose of Greek archaeology, followed by a long swim, a generous lunch, and time to stretch out on deck. The day begins at Agios Ioannis Diakoftis, where you board a large gulet and leave Mykonos behind.

I like the one-two punch of history and sea time. Delos gives the outing a purpose beyond sunbathing, while Rhenia supplies the easy pleasure of jumping into cool water. I also like the friendly, attentive crew, who keep drinks moving, help with swimming gear, and look after passengers who need a hand.

The main caution is practical: getting on and off the boat can be awkward, especially in choppy water, and the return sail may feel rough after lunch. Delos is also hot and exposed, while the roughly 90 minutes on shore can feel short if you want a close look at everything.

Key points to know before you book

• Delos is the star attraction: Explore an ancient island associated with Apollo and protected as a UNESCO site.
• Rhenia brings the water time: Swim, snorkel, or relax near a sheltered bay while lunch is prepared.
• The food is more than a token buffet: Expect grilled pork sticks, beef and lamb kebabs, vegetables, Greek salad, tzatziki, seasoned rice, and fruit.
• The boat is spacious but barefoot: You remove your shoes on board, and the boats may carry up to 30 or 40 people depending on the departure.
• The $151 price includes useful extras: Lunch, drinks, Wi-Fi, snorkeling equipment, insurance, and a host are included, but Delos admission and transfers cost more.
• Sea conditions matter: Calm weather can make this a superb day, but wind and chop can make boarding and the return journey tiring.

Why this six-hour cruise works so well

This is not simply a sightseeing boat with a quick photo stop. The day has three distinct parts: the crossing from Mykonos, a visit to Delos, and a long stop at Rhenia for swimming and lunch.

That mix matters. If you spend all day on a beach, you may wish you had seen Delos. If you spend the whole day among ruins, you may wish for a swim. Here, you get both, though neither part is unlimited. Delos receives about an hour and a half, and Rhenia receives about two and a half hours, with sailing time filling out the rest.

The cruise starts at 9:30 a.m. from Agios Ioannis Diakoftis. You receive a basic safety briefing and an outline of the day from a crew member. There is also a QR code with more information, and life jackets are available if you need or request one.

The operators use one of two gulets, depending on group size. Andreas is an 89-foot boat with a stated maximum of 40 people, while Atlantis is a 72-foot boat with a stated maximum of 30. The overall activity can reach 70 people, though the boats themselves are assigned by group.

You go barefoot once aboard. That is both a safety rule and a comfort choice, so wear shoes that are easy to remove. The boats are described as wide and comfortable, but you should not expect a private yacht charter. This is a shared cruise with room to lie back, eat, and move around.

Leaving Agios Ioannis for the Cyclades

The first stretch is the pleasure of being on the water. Mykonos is famous for its wind, and that wind can make the sail feel lively rather than calm. On a smooth day, you can settle into a drink and watch the island recede. On a breezier day, you will feel the boat working through the waves.

The crew serves coffee, tea, soft drinks, water, beer, and white and red wine as part of the trip. Cocktails and other alcoholic drinks are available to buy, but they are not included. Wi-Fi is also included, though the best reason to be on deck is to look up from your phone.

The crossing to Delos takes about 40 minutes. That is enough time to get comfortable, hear the plan for the day, and decide whether you want to explore the ruins or remain on board during the Delos stop.

If you are prone to seasickness, take the sailing seriously. The boat is large, but size cannot erase rough water. Some days are wonderfully calm. Other days can be windy and choppy, especially on the return. Keep sunscreen, water, and a light jacket handy, and consider where you sit if motion bothers you.

Ancient Delos in 90 minutes

Delos is the cultural heart of the trip. The island is identified with the birth of Apollo and is protected as a UNESCO archaeological site dating to around 3500 BC. Its ruins make clear why this is not just another pretty Greek island stop.

You can prebook a professional guided tour for an additional 45 euros per person, or explore independently after paying the 20 euro entrance fee. If you choose the self-guided option, take a moment before leaving the boat to understand the meeting time. The boat cannot wait for a slow wander.

The allotted time is about an hour and a half. That is enough to see major remains and get a feel for the scale of ancient Delos, but it is not enough for a leisurely study of every corner. A guide can help you use the time well, especially if ancient Greek history is new to you. The crew also gives an overview of the island, but that is not the same as a full archaeological tour.

Delos is hot, bright, and exposed. Bring a hat, water, sturdy comfortable footwear for shore, and plenty of sunscreen. The contrast is part of the day’s charm: you walk among pale stone and old sanctuaries, then return to the boat for a cold drink and a swim.

If you would rather not walk the ruins, you can stay aboard while the group visits Delos. The boat remains close to a bay, giving you time to sunbathe or swim. That choice suits anyone who has already visited Delos, dislikes hot archaeological sites, or simply wants a more relaxed day.

The 20 euro entrance fee is not included in the base price. Add it when comparing the total cost. The guided option brings the cost up again, but it may be worthwhile if the ancient site is the main reason you booked.

Rhenia brings the reward of clear water

After Delos, the boat continues to Rhenia, sometimes spelled Rineia. This is the day’s most relaxed stop. The boat anchors near water described as a natural pool, and you can swim straight from the boat, use the provided snorkeling gear, or stay dry on deck.

The crew has swimming noodles and life jackets for anyone who is not a confident swimmer. Tell the crew what you need rather than trying to manage alone. Masks and snorkels are provided, though fins are not. The water is clear enough to look toward the rocks and spot fish, though this is casual snorkeling rather than a full reef excursion.

You have about two and a half hours here. That gives you time for a swim, a rinse, a plate of food, and another swim. It also means you are not rushed into the water for five minutes before moving on.

The setting can still be shared with other boats, especially on a popular summer day. Even so, the experience is more about open water, sun, and a good meal than about finding an empty cove. If you want a private beach, this is not that. If you want a comfortable place to swim without arranging your own boat, it works well.

The crew keeps the mood easy and attentive. Dimitri and Thomas have been especially helpful with passengers who needed assistance, including one mother with mobility concerns. That kind of practical care matters on a boat, where a steady arm can make boarding, swimming, and moving around far less stressful.

The onboard BBQ is a real part of the value

Lunch is served as a buffet after the swimming stop. The menu includes grilled pork sticks, beef and lamb kebabs, grilled eggplant, zucchini, mushrooms, Greek salad, tzatziki, seasoned rice with vegetables, and seasonal fruit salad.

That is a substantial meal for a day on the water. You are not limited to a sandwich or a small box of snacks. The food is freshly prepared on board, and drinks are included with lunch and throughout the cruise. Beer, wine, coffee, tea, soft drinks, and water are part of the package.

The timing makes sense. You first get into the water, then return to the boat for food. If you are sensitive to motion, be aware that the sail back follows lunch. On rougher days, the combination of a full stomach and choppy seas can be unpleasant. Eat at a sensible pace, drink water, and give yourself time before settling into the return crossing.

Vegetarians have grilled vegetables, salad, rice, tzatziki, and fruit, though the supplied menu does not describe a separate vegetarian main course. If you have serious dietary restrictions, ask the provider before booking rather than relying on the buffet to meet your needs.

The return sail can be the toughest hour

The route back to Agios Ioannis takes about an hour. On a calm day, it is a pleasant close to the trip. After swimming and lunch, you can stretch out on the comfort deck, talk with the crew, or watch the coast return.

On a windy day, this is where the cruise may lose some of its shine. Several parts of the Aegean can become rough without warning, and the boat’s size only helps so much. The crew’s priority is safety, and the itinerary may change if conditions are poor.

You receive notice the evening before if the weather is unsuitable for the planned cruise. The operator may offer another date or a full refund if the activity is canceled for weather. That is useful flexibility, but it also means you should avoid scheduling this as the one activity you cannot miss during a short stay.

What the $151 price really covers

At about $151.16 per person, this is not the cheapest way to see Delos. But the price includes far more than transport to an archaeological site.

You receive the boat trip, host, lunch, snorkeling equipment, personal insurance, Wi-Fi, and a good range of drinks. You also get the Rhenia swimming stop, which would require a separate boat arrangement if planned on your own.

The extras are important. Hotel pickup and drop-off costs 20 euros per person and must be arranged in advance. Pickup usually takes place 30 to 60 minutes before departure, with the driver contacting you the evening before. The Delos admission fee is 20 euros per person, and the professional guided tour is another 45 euros per person.

For a simple comparison, a couple choosing the base cruise, round-trip transfer, and Delos admission would pay roughly $302.32 before those euro charges are converted. Add the guided visit and the total climbs again. The package remains good value if you want a full day with food and swimming, but it is less attractive if you only want a short archaeological visit.

If you are staying near Agios Ioannis and can reach the meeting point easily, skip the transfer. If you are in Mykonos Town, have luggage, or are arriving from a cruise ship, the paid pickup may be worth the convenience. Make sure it is reserved ahead of time, since it is not automatic.

Who will enjoy this cruise most

I would choose this for someone who wants a full Mykonos day with a little of everything. Families with older children and teenagers should find plenty to do, from exploring Delos to jumping into Rhenia’s water. Couples can spend much of the day lounging with a drink, while active passengers can swim and snorkel.

It also suits you if you like guided travel but do not want to be led around every minute. You can pay for the Delos guide, explore on your own, or stay aboard during the archaeological stop.

I would be cautious if you have major mobility limits. Boarding may involve a moving gangplank, and getting on and off can be difficult in rough water. Crew members can assist, but the operator does not present the boat as fully accessible.

This is also not ideal if you want a quiet, private sailing day. The cruise is shared, the group size can be significant, and the water may be lively. You should also be comfortable removing your shoes and stepping carefully around a boat deck.

Free cancellation is available up to 24 hours before the 9:30 a.m. start. Changes or cancellations inside that window are not accepted, except when poor weather causes the operator to cancel. You must provide passport, ID, or driving license details when booking for insurance purposes, along with a valid phone number for cruise and transport updates.

Should you book the Delos and Rhenia cruise?

I would book it if you want history, swimming, and a filling meal in one well-paced day. The crew care, spacious boats, included drinks, and strong lunch make the price easier to justify. Delos gives the cruise substance, while Rhenia keeps it from becoming an all-day walk over hot ruins.

Book the guided Delos option if archaeology is your main goal. Choose self-guided Delos if you prefer freedom and want to keep the cost down. If swimming matters more than ancient stones, stay aboard during the Delos stop and enjoy the water near the island.

Go in with realistic expectations about the sea. Calm weather can make this one of the best days of a Mykonos visit. Wind, rough boarding, and a choppy return can make it tiring. Bring sunscreen in generous quantities, a hat, swimsuit, light jacket, and a little patience. The result is a rewarding Greek island day, not a guaranteed smooth-water postcard.
