Ancient Delos and easygoing Rhenia make a fine two-island pairing, and this seven-hour shared cruise lets you see both without paying for a private boat. You sail from Mykonos to Delos, then spend time swimming and resting around Rhenia, with a light lunch and drinks included.

I like the choice built into the day. You can pay separately to walk through Delos’s famous archaeological site, or stay on the boat and swim. I also like the small maximum group of 15 people, which should feel more personal than a large excursion boat.

The main caution is the sea. Wind can turn the return trip into a rough ride, and one particularly bad outing left passengers seasick. Check the forecast, bring sun protection and motion-sickness supplies if you need them, and understand that the destination or route can change in poor weather.

Key points to know before you book

• Two very different islands: Delos offers major ancient ruins, while Rhenia is for swimming, sun, and a slower pace.
• Lunch and drinks are included: You do not need to arrange food for the day, though the included meal is described as light.
• Delos admission costs extra: The archaeological site and museum are not included, and there is no professional guide at the ruins.
• Swimming is part of the appeal: You may swim from the boat near Delos and spend additional swim time at Rhenia.
• The boat holds up to 15 people: This is a shared cruise, but the group limit is modest.
• Weather matters: Strong winds can make the crossing choppy, alter the destination, or cancel the cruise.

Why Delos and Rhenia work well together

Mykonos is famous for whitewashed lanes and late nights, but the nearby islands offer a useful change of pace. Delos gives you ancient stones and sacred history. Rhenia gives you open water, a beach break, and time to do very little.

That contrast is the real reason to book this outing. A day spent only at Delos can feel hot and demanding, especially if you try to see the major ruins on foot. A day spent only on a swim boat can feel pleasant but a little thin. Put the two together and you get culture in the morning and relaxation later.

The cruise is also a practical alternative to hiring a private boat. At $116.36 per person, the price is not a bargain-basement ferry fare, but it covers a full day on the water, lunch, beverages, local taxes, and access to two islands. A private charter can cost far more once the boat, crew, fuel, and food are added.

Your value depends on how you use the options. If you visit the Delos ruins, swim at Rhenia, and enjoy the boat ride, the price makes sense. If you remain aboard at Delos and find the sea too rough for swimming, the same fare may feel less attractive.

Setting out from Mykonos at 10:30

The listed meeting point is at Olia Hotel, Mykonos, with the activity ending back at the meeting point. The start time is 10:30 a.m., and the total experience lasts about seven hours. That gives you a full afternoon on the islands without forcing you into an extremely early start.

Pickup and return hotel transfers are not automatically included. You can upgrade for that convenience, but you need to provide your preferred pickup location by 3 p.m. on the previous day. Give the operator the hotel name or cruise ship name. If you are staying in an apartment, provide a map, nearby hotel, or another clear landmark.

This matters on Mykonos. Some accommodations sit in pedestrian areas, and some villas are far from the main roads. For remote areas such as Elia, Kalafatis, Agrari, Panormos, Super Paradise, and Kanalia, an extra €10 per person may apply for transfers, paid in cash. The operator may assign a convenient meeting point when a property has no clear name or vehicle access.

If you arrange your own way to the start, be precise and arrive early. The company waits up to 15 minutes for late passengers, but even a short delay can disrupt the transfer schedule. A missed meeting point is not treated as the operator’s responsibility.

Delos: choose ruins or a swim

The first major stop is Delos, one of the most important ancient sites in Greece. The planned stop lasts about two hours, which is enough for a focused visit but not for a leisurely look at every corner.

The key decision is made before you arrive. The archaeological site and museum cost extra, and a professional guide is not included. If you want context, you will need to explore independently unless you arrange guidance separately. Bring your own plan for what you want to see, because two hours passes quickly among scattered ruins.

The site is valuable even without trying to see everything. Delos was a major religious and commercial center in the ancient Cyclades, and its remains give you a stronger sense of the region than a museum display alone. Streets, foundations, columns, mosaics, and open archaeological areas help you picture an entire ancient settlement rather than a single surviving monument.

There is also a practical side. Delos can be hot, exposed, and tiring. Wear sturdy shoes, carry water, and protect yourself from the sun. The provided lunch comes later as part of the cruise, so do not count on it to solve your needs during the site visit.

If ancient history is not your priority, you can stay with the boat and swim instead. This is a useful choice for anyone who has already seen major Greek ruins or simply wants a lighter day. The swim option also helps if the heat makes two hours of walking unappealing.

Do not assume the two choices offer equal conditions every day. Wind and sea conditions can affect how long the boat remains in one spot and how comfortable swimming feels. Ask the crew about the plan when you board, especially if you are choosing Delos for the water rather than the ruins.

Rhenia brings the slower half of the day

After Delos, the cruise continues to Rhenia. Here the focus shifts from archaeology to swimming, sun, and a break from the movement of the boat.

Rhenia is the part of the experience where you can settle into the day. You might swim from the boat, sit in the sun, or simply enjoy lunch and the surrounding sea. The appeal is not a long list of scheduled sights. It is the chance to spend time in a quieter setting near Mykonos.

The water may be cold, even in warm weather. That did not stop people from enjoying the swim, but it is worth knowing before you leap in. Bring a swimsuit, towel, sunscreen, hat, and a dry layer for the return ride. The supplied information does not specify a detailed packing list, so basic beach gear is your safest approach.

One point needs clarification before booking: the exact swim setup can vary. Some passengers may expect a roomy beach stop and instead find a boat-based swim less satisfying. Ask whether the day’s Rhenia stop will use a beach or a swim-from-the-boat arrangement, since conditions can influence the plan.

The best version of this stop comes when you treat it as unhurried time rather than a major attraction. Rhenia pairs nicely with Delos because it lets your mind shift gears. After two hours among ruins, a swim and a simple meal can be exactly what you need.

Lunch, drinks, and life aboard

A light lunch and beverages are included. The meal has received especially warm praise, with people describing it as excellent and delicious. That is important on a seven-hour outing, since finding food independently between boat departures and island stops would be awkward.

Still, light lunch means you should not assume a large restaurant meal. If you have a big appetite, dietary needs, or strong food preferences, confirm what is offered before departure. The supplied details do not list the menu or special-diet arrangements.

The boat ride itself is part of the experience, not just transportation between stops. On a calm day, the crossing gives you a pleasant view of the Cycladic islands and a chance to sit back between activities. The crew has also been described as friendly, caring, and professional, with particular praise for hosting and attentiveness.

Sea conditions are the big variable. One outing began pleasantly but became extremely choppy as the wind increased in the afternoon. Several people became seasick, and the return was described as frightening. That does not mean every departure will be rough, but it shows why you should take the weather warning seriously.

If you are prone to motion sickness, speak with a medical professional about suitable medication before the trip. Sit where the boat moves least, look toward the horizon, drink water, and avoid arriving with a heavy meal. These are sensible precautions for any island cruise, especially one crossing open water.

Group size, transfers, and what is not included

The maximum group is 15 people. That is a meaningful advantage over a packed excursion with dozens of passengers. You still share the boat, but the smaller capacity should make it easier to hear crew instructions and ask questions.

There is no professional guide at Delos. This cruise is best understood as transport and free time rather than a guided archaeological tour. If you want a detailed explanation of the ruins, factor in the cost of a guide or prepare to explore on your own.

Delos entrance and museum admission are also excluded. The tour information describes the Delos stop as free in the itinerary while separately stating that the archaeological entrance fee and museum are not included. Treat the site admission as an extra cost and confirm the current fee before departure.

Hotel and port transfers are another optional extra. The cruise itself begins and ends at the stated meeting point, so check the location against your accommodation. The transfer upgrade may be worth paying for if you are staying far from Mykonos Town, arriving by cruise ship, or carrying beach gear.

The boat can carry children only when accompanied by an adult. Most people can participate, but the experience involves boarding a boat, walking around an archaeological site if you choose that option, and dealing with possible movement at sea.

Weather rules deserve close attention

The cruise requires suitable weather. Strong winds over force six on the Beaufort scale can lead the operator to cancel, and the destination may change when conditions shift. The duration can also vary depending on the weather.

If the operator cancels because of poor weather, the booking terms say you will be offered another date or a full refund. The provider’s conditions also state that, when it cancels because of high winds, an 80 percent refund may apply, with a date change or alternative activity offered first. Because those terms differ, read the final cancellation conditions shown at booking and ask for clarification if weather is a concern.

You can cancel for a full refund when you give at least 24 hours’ notice. Cancellations or changes inside that window are not accepted for a refund. Last-minute flight problems or being unable to leave a cruise ship are also not accepted as automatic reasons for reimbursement, so do not book this for the same day you have an uncertain arrival.

I would avoid placing this cruise on a tight schedule. If you have a flight or ferry soon after the expected return, the weather policy and possible delays matter. Give yourself breathing room.

Who will enjoy this day most

I would recommend the cruise to you if you want a mix of ancient Greece and swimming, prefer a shared boat to a costly private charter, and like having lunch arranged. It suits couples, friends, and families with children who can manage a full day on the water.

It is also a good fit if you want choices. At Delos, history-minded passengers can pay for the ruins while others stay with the boat. At Rhenia, you can swim or simply rest. That flexibility keeps the day from feeling like a rigid march from one scheduled stop to the next.

I would be cautious if you dislike boats, become seasick easily, or need a guaranteed calm-water experience. The strongest negative experience came from rough conditions, not from the idea of the islands themselves. You should also look elsewhere if a guided archaeological visit is your main goal.

For a first visit to Mykonos, this cruise gives you a useful view beyond the main island. It does not replace a proper Delos tour for history lovers, and it is not a luxury yacht charter. It is a practical middle ground.

Should you book the Delos and Rhenia cruise?

Book it if you want two contrasting island stops, included food, and a smaller shared group at a reasonable price for a full day. The combination of Delos ruins, Rhenia swimming, and a friendly crew creates a strong day when the sea is calm.

Before paying, check three things: the weather forecast, the extra cost of Delos admission, and the transfer arrangement from your accommodation. Bring swimwear, a towel, sun protection, sturdy shoes, and motion-sickness supplies if needed.

My final call: this is a good-value choice for an active but flexible day from Mykonos, provided you accept that the sea controls the schedule. It is less suitable for anyone seeking a fully guided history tour or a guaranteed smooth ride.
