Shared Mykonos Sail Cruise to Delos and Rhenia Islands

Ancient Delos is the star here: a 3,500 BC archaeological site linked with Apollo, reached by boat from Mykonos. You get about 90 minutes to walk among the ruins, then return to a comfortable yacht for swimming, snorkeling, and lunch near Rhenia. I especially like the choice between exploring Delos and staying aboard, plus the crew’s steady care, from swim noodles to regular drink service.

The barbecue buffet is another strong point, with grilled meat, vegetables, Greek salad, tzatziki, rice, fruit, and wine or beer included. The main caution is the sea and the boarding: choppy water can make the ride rough, and the loose gangplank may be hard for anyone with mobility issues.

Key points to know before booking

• Delos and Rhenia in one day: Combine a major archaeological site with a peaceful swimming stop.
• A proper lunch comes with the sailing: Expect grilled pork, beef and lamb kebabs, vegetables, salad, tzatziki, rice, fruit, and drinks.
• You choose your Delos style: Pay extra for a professional guide, or explore independently for about 90 minutes.
• Swimming gear is supplied: Snorkels, masks, noodles, and life vests are available, though fins are not listed.
• The yacht is spacious but the sea can be rough: The boats carry up to 30 or 40 people on the named vessels, with a maximum tour size of 70.
• Transfers and entrance fees cost extra: Hotel pickup is 20 euros per person, while Delos admission costs 20 euros and the guided tour costs 45 euros.

Why Delos and Rhenia make a smart Mykonos day

Mykonos is famous for whitewashed lanes, beach clubs, and strong summer sun. This cruise gives you a different side of the islands. You spend part of the day in one of the Aegean’s most important ancient sites, then trade stone ruins for clear water and a long lunch aboard a yacht.

That combination is the real value. A land excursion to Delos gives you archaeology, but this trip adds the pleasure of getting there by sea and swimming near Rhenia. A standard boat outing may give you water time, but not the chance to walk through a major sacred center of the ancient Greek world.

The tour costs $151.16 per person, which is not a bargain-basement boat ride. Still, the price includes roughly six hours on the water, the yacht, a host, insurance, snorkeling equipment, a full lunch, soft drinks, coffee, tea, wine, beer, and water. Once you count a separate meal and a boat trip, the package makes reasonable sense.

Just remember that the two most important extras are not included. Delos admission is 20 euros per person, and a professional guided tour costs 45 euros. Hotel pickup and drop-off cost another 20 euros per person, paid in advance. If you are staying near the meeting point at Agios Ioannis Diakoftis, you can avoid that transfer fee.

Starting at Agios Ioannis Diakoftis

The cruise begins at 9:30 a.m. at Greece Sailing in Agios Ioannis Diakoftis. This is not a town-center departure, so check your transport plan before the morning of the cruise. If you buy the round-trip transfer, the driver normally contacts you the evening before and arranges pickup about 30 to 60 minutes before sailing.

You board one of two gulets depending on group size: Andreas, an 89-foot boat with a stated maximum of 40 people, or Atlantis, a 72-foot boat with a stated maximum of 30. The total activity can accommodate up to 70 people, but the boats are described as wide and comfortable, with space to sit back even when full.

At the start, a crew member gives basic safety instructions and explains the day’s route. You can also use a QR code for the information. Life vests are available if you need one or ask for one.

One practical detail matters: everyone goes barefoot on board for safety and comfort. Wear something easy to remove, and keep a light jacket handy in the early or late season. The wind can make the first and last parts of the day feel cooler than expected.

Sailing toward Delos

The ride to Delos takes about 40 minutes. On a calm day, this is a pleasant stretch of open water with views back toward Mykonos and across the surrounding islands. On a windy day, it can feel more like an active sail than a gentle cruise.

That distinction is worth taking seriously. Several accounts of the outing describe rough or choppy conditions, especially on the return. The crew cannot control the weather, and the yacht’s size helps but does not remove the motion of the sea. If you are prone to seasickness, sit where the movement feels easiest and avoid assuming that a sunny day means calm water.

The boat has Wi-Fi, drinks, and a host on board. The crew, including Dimitri and Thomas on some departures, is especially hands-on with drinks, equipment, and help around the yacht. Marissa has also helped arrange difficult meeting plans for passengers in the past, which shows how useful it is to communicate clearly before departure if you are arriving from a cruise ship or another part of Mykonos.

Walking ancient Delos for 90 minutes

Delos is the cultural heart of the excursion. The island is linked with Apollo and is protected as a UNESCO archaeological site. The ruins give you a chance to see the remains of a major ancient settlement rather than simply admire the island from offshore.

You have about an hour and a half on land. That is enough for a focused walk through the main ruins, but it is not a full archaeological study. If you want context, reserve the professional guided tour for 45 euros per person. If you prefer to move at your own pace, choose the self-guided option and use the time to see the site independently.

The guided option is especially useful because the stones and foundations can be hard to read without explanation. A guide can connect the streets, temples, homes, and public spaces into a clearer picture. Without one, you will still see an extraordinary place, but you may spend more time trying to work out what you are looking at.

Bring water, a hat, and sunscreen. Delos is exposed, and the sun can be intense even when the boat ride feels breezy. There are water vending machines near the museum shop, but you should not depend on finding shade or a convenient refill at every point on the island.

The time limit is the main drawback for history lovers. One hour and 30 minutes gives you a strong introduction, but some people will want longer. You may need to choose between a careful look at the museum and a broader walk through the ruins. If ancient sites are your main reason for booking, the paid guide is probably money well spent, but the schedule still remains fairly tight.

There is also a useful alternative. You can stay aboard while the other part of your group visits Delos, using that time to sunbathe or swim in a nearby bay. This makes the cruise work for mixed groups, such as one person who loves archaeology and another who would rather spend the morning on the water.

Rhenia brings the swimming and lunch

After Delos, the boat continues to Rhenia, usually called Rineia in the route details. The stop lasts about two and a half hours, making it the longest part of the day.

The water here is the reason many people remember the cruise. You can swim from the yacht, use the complimentary snorkeling equipment, or simply stretch out on deck. The crew provides noodles and life vests for anyone who is not a confident swimmer. Masks and snorkels are available, but fins are not listed, so do not expect a full fin-and-mask snorkeling setup.

The water is described as pool-like, though conditions vary. You may see fish near the rocks, but this is casual snorkeling rather than a dedicated marine-life expedition. I like that you can make the stop as active or lazy as you want. Jump in, float for a while, then return to the boat for a drink and lunch.

The meal is prepared and served on board. The barbecue includes grilled pork sticks, beef and lamb kebabs, eggplant, zucchini, mushrooms, Greek salad, tzatziki, seasoned rice, and seasonal fruit salad. Coffee, tea, soft drinks, water, white wine, red wine, and beer are included.

This is much more useful than a token snack. You get a proper meal after the Delos walk, and the menu gives you familiar Greek flavors without turning lunch into a formal event. Cocktails and other alcoholic drinks cost extra, but you do not need to buy drinks to get through the day comfortably.

The long Rhenia stop also keeps the cruise from feeling rushed. You have time to eat, swim, dry off, and enjoy the view. If the weather is cool, you can skip the water and remain on deck. The boat itself becomes the attraction.

Crew service and the feel on board

The strongest part of the experience is the crew. The staff regularly checks that people are comfortable, offers drinks, helps with swimming equipment, and assists with boarding. Dimitri and Thomas have been singled out for helping an older passenger with mobility concerns, which gives you a good idea of the service style.

The atmosphere is relaxed rather than built around loud music or a party crowd. Families, couples, older visitors, and teenagers can all fit into the day. You get a social boat experience, but the spacious gulet and long swimming stop leave room for quiet time.

That said, the boat is not a private yacht. The group may be large, with a maximum of 70 people overall, and the amount of personal space depends on the departure. The information about the named boats suggests lower numbers on those vessels, but the final group size can vary.

Boarding deserves a clear warning. The gangplank is not fixed to the dock, and wind or wave movement can make getting on and off awkward. Crew members are there to help, but this is not the best choice if you need a stable, step-free boarding arrangement. Once aboard, the boat is comfortable. The difficult moment is getting between dock and yacht.

Timing, transfers, and what to pack

The full day lasts about six hours, beginning at 9:30 a.m. and returning to Agios Ioannis Diakoftis. The route includes about 40 minutes sailing toward Delos, 90 minutes exploring or staying aboard, two and a half hours at Rhenia, and about an hour for the return portion.

The stated timing is approximate, since wind and sea conditions affect sailing. Poor weather can lead to a changed route or cancellation, with a different date or full refund offered. You can cancel for a full refund up to 24 hours before the start time, but changes or cancellations inside that window are not accepted.

Bring:

• Swimsuit
• Hat
• High-factor sunscreen
• Comfortable clothes
• A light jacket in cooler months
• Identification details supplied during booking

Passport, identity card, or driving licence details are required for personal insurance. A working phone number is also important for cruise and transfer messages.

If you are coming from a cruise ship, arrange the transport early. The transfer is available for 20 euros per person, but it must be reserved in advance and paid ahead of time. Do not assume that the yacht will wait at a port pickup point without a clear arrangement.

Who will enjoy this cruise most

I would choose this trip if you want one substantial day that mixes culture, food, scenery, and swimming. It suits couples, families with older children, and anyone who likes the idea of seeing Delos without giving up a full afternoon on the water.

It is also good for groups with different interests. One person can explore the ruins while another stays aboard, and everyone meets later for lunch and swimming. The crew’s willingness to help also makes it workable for some older passengers, provided they can manage the unstable boarding point with assistance.

I would think twice if you need very steady footing, dislike boat motion, or want a long and detailed visit to Delos. The sea may be rough, and the archaeological stop is limited to about 90 minutes. This is a combined island day, not a specialist archaeology tour.

Should you book the Delos and Rhenia sailing?

Yes, if you want a well-rounded Mykonos outing and can handle a moving boat. The best parts are the mix of ancient Delos, clear Rhenia water, a generous barbecue lunch, and a crew that pays attention to the small practical details.

Before paying, add the extras to your real budget. With Delos admission, a guide, and hotel transfers, the final cost can rise well above the base price. Also confirm your transport to Agios Ioannis and be honest about mobility needs.

For most people who want more than a beach day, this is a strong choice. Book it for the full Greek-island feeling: old stones in the morning, a swim after lunch, and a yacht ride home with the wind in your face. Just hope for calm seas.
