The best overall boat tour in Mykonos is the Delos and Rhenia combination cruise: history, crystal-clear swimming, a guided introduction to one of the most significant archaeological sites in the Aegean, and lunch on board, all in a single five to six hour day. For pure sailing enjoyment around the island’s coastline, a semi-private catamaran tour covers the south coast beaches and hidden coves with food, wine, and swimming stops. For total flexibility and a private experience, a charter beats a group tour every time.
The right boat tour depends on two variables: what you want the day to feel like, and how many people you are traveling with. Solo travelers and couples on a standard budget fit naturally into semi-private group tours, which run with anywhere from eight to twenty-five passengers depending on the operator and vessel. Families with children or groups of six or more often find that a private speedboat or small catamaran charter costs less per head than the semi-private equivalent once you run the numbers, and delivers a day that is fully shaped around your group rather than whoever else booked the same slot.
From our work with over 13,500 travelers on the island, the boat tour category generates the highest rate of post-trip recommendation of anything we arrange. People who almost skipped it because they were not sure it was worth it are the ones who most often tell us it was the best day of their trip.
Want to make the Mykonos boat party experience actually worth the day rather than just a box ticked on a Greek island checklist? Here’s our Mykonos boat party guide so you pick the right one.
The Delos and Rhenia cruise combines a visit to the UNESCO World Heritage archaeological site of Delos with swimming stops at Rhenia, the uninhabited island immediately adjacent to Delos. Rhenia has no permanent population, no beach clubs, and no facilities, only an extraordinary clear sandy-bottomed sea in protected bays that see a fraction of the crowds of Mykonos’s own beaches. Together, the two islands make for the most complete single-day experience available from Mykonos.
Delos sits around six miles southwest of Mykonos, a 30-40 minute crossing by boat. It was once one of the most important trading and religious centers in the ancient Mediterranean: the mythological birthplace of Apollo and Artemis, a Panhellenic sanctuary, and a city that at its peak housed around 25,000 people from across the known world. The entire island is an archaeological site under Greek law, meaning there are no hotels, no residents, and no development. What remains are the ruins of temples, marketplaces, theatres, private houses with intact floor mosaics, the famous Terrace of the Lions (the originals now housed in the on-site museum), and the view from Mount Kynthos across the entire Cyclades. Going with a licensed guide changes the experience completely. The ruins are extensive and without context can read as ancient rubble. With a guide, they read as an ancient city.
Rhenia, a short sail from Delos, is where the swimming happens. Uninhabited, protected, and with the kind of water clarity that results from a bay that sees no motorized traffic and no development upstream, it is one of the better swimming spots in the entire Cyclades. Boats anchor in the bay and passengers jump directly into the water from the deck, a moment that consistently appears in people’s best-of-trip descriptions. On group tours, lunch is served on board between Delos and Rhenia, typically a proper Greek spread: grilled meats, Greek salad, tzatziki, fresh bread, wine and beer included. It is a full day, comfortably five to six hours from departure to return.
Practical notes from people who have done it: wear proper shoes with grip for Delos, the terrain is rocky and uneven. Bring a hat and significantly more water than you think you need. The island has no shade and no shops. Sunscreen applied before departure, not on the boat. The boat does not dock at Rhenia: passengers swim from the anchored vessel, so being comfortable in open water is a requirement. Those who prefer not to swim can stay on deck.
If you’d rather have us arrange this rather than navigating the booking options yourself, the Mykonos Tours team books guided Delos and Rhenia cruises with vetted operators and handles the logistics.
Delos is one of Greece’s most important archaeological sites and it’s a 20-minute boat ride from Mykonos – our Delos tour from Mykonos guide breaks down what’s actually there, how long you need, and whether a guided tour adds enough to justify the cost.
A standard semi-private catamaran tour runs five to six hours, departs from Ornos Bay, covers the south coast of Mykonos and typically includes stops at Rhenia for swimming, a view of Delos from the water, and two or three swimming stops in coves not accessible from land. Lunch is cooked fresh on board by the crew, wine and beer are included, and group size is typically capped at ten to twenty-five passengers. Expect to pay €90-180 per person depending on the operator, group size, and inclusions.
The catamaran is the right vessel for this kind of day. It is stable enough to handle moderate Aegean chop without producing the rolling motion that affects smaller motorboats in similar conditions. The deck space is generous: most catamarans used for tour operations have a forward trampoline net for sunbathing, a shaded stern area, and an interior cabin for those who want out of the sun. Departures are from Ornos Bay rather than the old port, reached by a short tender boat from the beach.
The quality variation between operators is significant and worth researching before booking. The things that separate good from average: fresh food cooked on board rather than pre-packaged, capped passenger numbers (ten to sixteen is genuinely semi-private; twenty-five is the edge of comfortable), a crew that knows the waters and adjusts for wind conditions intelligently, and a clear alternative itinerary communicated in advance for high-meltemi days. Semi-private catamaran tours with eight to twelve passengers on board are the format that consistently generates the best reviews, and they cost moderately more than the larger group version.
Most catamaran tours include a Delos flyby rather than a landing: the boat anchors offshore while the captain gives a summary of the site’s history and significance. This gives passengers the context without the full guided archaeological visit. Travelers who want to actually walk Delos and spend time in the museum are better served by booking a Delos-specific tour or combining the two as a separate day.

A private boat charter gives your group full control of the itinerary, timing, and pace. You choose where to go, how long to stay, and when to eat. The vessel, crew, and day belong to your group alone. Private charters make financial sense for groups of six or more when the per-person cost of a charter approaches the semi-private equivalent. They make experiential sense for any group that values flexibility and privacy above the social atmosphere of a shared tour.
The charter market in Mykonos runs from small speedboats and RIBs at the affordable end to sailing catamarans, motor yachts, and full luxury superyachts at the premium end. A private half-day RIB or speedboat charter for up to eight passengers starts around €800-1,500 depending on the vessel and season, covering a custom route with fuel and a licensed skipper included. A full-day private catamaran for ten to twelve passengers runs €1,600-3,500. Motor yachts suitable for larger groups start around €2,200 per day in shoulder season and climb to €3,700 and beyond at peak summer. At the luxury end of the market, superyachts of 88 feet and above run significantly higher.
The most common private charter itinerary we arrange for first-timers: depart Ornos or Tourlos, sail to Rhenia for a morning swim stop in the clearest water of the day, continue to Delos for a view of the archaeological site or a landing if the group wants it, then follow the south coast back past Paradise and Super Paradise Beach to Psarou, arriving back mid-afternoon. This covers the two most significant offshore destinations from Mykonos in a single half-day at a pace determined by the group.
A first trip to Mykonos needs different planning than a return visit and the priorities look very different once you know what the island actually delivers – our Mykonos tours for first-time visitors guide breaks down exactly where to focus your limited time and budget.
A Mykonos sunset catamaran tour is the best-value boat tour format on the island: three to four hours departing in the late afternoon, with swimming stops while the sun is still high, then food and drinks served as the light drops over the Aegean. The photography is exceptional. The temperature is gentler than the midday crossing. And the experience of watching the sun go down from the water, with Mykonos’s coastline and the distant silhouettes of other Cycladic islands behind you, is one of those things that a photograph approximates but does not contain.
Sunset tours typically depart from Ornos around 4-5pm, cruise the south coast and out toward Rhenia or nearby coves, and return as darkness settles, usually by 9pm. Some operators anchor off Little Venice for the final section of the evening, giving passengers a view of the Chora waterfront from the sea as the island lights come on. The DJ-party sunset boat format, which departs from the old port with an onboard DJ and music at higher volume, is a distinct product targeting a different traveler: it suits groups wanting the sunset plus an evening party atmosphere, less so couples or families after a quieter experience. Know which version you are booking before committing.
The light during a Mykonos sunset tour in June and September is what photographers come for. The Aegean sky goes through pink, orange, and amber in sequence, and the white of the island’s buildings catches and holds each phase. On a clear day in late May or early September, when the meltemi has not yet arrived or has already eased, a sunset on the water around Mykonos is genuinely extraordinary.
We’ve been arranging Mykonos boat tours since 2012. Talk to the team about which sunset tour format fits your group.

Match the tour format to your group size, budget, and what you actually want from the day. Solo travelers and couples on a standard budget: semi-private catamaran tour covering Delos, Rhenia, and the south coast. Families or groups of six or more: price out a private speedboat or catamaran charter, which often costs less per person than the group equivalent. Anyone who wants the history of Delos properly: book a guided tour with a licensed archaeologist rather than a general catamaran that passes Delos from offshore.
The group size calculation is worth doing before you assume a private charter is out of reach. A semi-private catamaran tour at €120 per person for a group of eight costs €960. A private half-day speedboat charter starts around €800 and takes the same eight people to the same places on their own schedule. At groups of six or above, the arithmetic often favors the private option before the intangible advantages of privacy and flexibility are even factored in.
The meltemi question should also factor into your choice. On strong meltemi days in July and August, smaller vessels take a rougher ride and are more likely to have itineraries altered by wind conditions. Catamarans handle moderate chop better than speedboats due to their beam width and stability. Good operators always have an alternative south-coast route ready for windy days, staying in the more sheltered waters below the island’s mass rather than heading to the more exposed northwest. Ask what the alternative itinerary is before you book, and check that the operator has a clear policy on meltemi cancellations and refunds.

The four things that most affect a Mykonos boat tour experience: meltemi wind conditions, seasickness preparation, what to bring that is not on the packing list operators provide, and booking lead time. In peak season, the best semi-private tours fill up one to two weeks in advance. Private charters should be confirmed as early as possible in summer months when the fleet is heavily booked.
The meltemi is the main variable. From late June through August, the north wind blows across the Aegean with variable intensity. On strong meltemi days, the crossing to Delos and Rhenia involves open water and noticeable swell. Good operators always have a sheltered alternative route along the protected south coast ready. If you are sensitive to motion, ask specifically about the planned route for your date and what the alternative is. Some operators cancel in genuinely bad conditions and offer full refunds; others proceed with the alternative route. Know the policy before you commit.
Seasickness preparation. The open-water crossing to Delos and Rhenia can be bumpy in moderate to strong meltemi conditions on a smaller vessel. If you are prone to motion sickness, take medication the night before and morning of rather than waiting to see how you feel. Sitting on deck rather than below, focusing on the horizon, and staying at the stern of the boat rather than the bow all help. Catamarans are more stable than speedboats in similar conditions. Sunset tours that stay closer to Mykonos’s sheltered south coast have calmer crossings than the full Delos runs.
What to bring that operators do not always mention. Delos has no shade, no shops, and no potable water from taps. Bring a proper insulated water bottle filled before departure and significantly more water than a normal beach day would require. The rocky terrain at Delos demands proper shoes rather than flip-flops: closed-toe shoes or firm sandals with grip. A hat that stays on in wind. Sunscreen applied before boarding rather than on deck. Cash for the Delos entry fee (€20 for adults as of June 2026), which is not always included in the tour price and is not payable by card at the site ticket booth.
Booking lead time. In July and August, the most popular semi-private catamaran tours fill up one to two weeks ahead. Private charters on the best vessels can book out further in advance than that. Book as soon as your Mykonos dates are confirmed rather than waiting until you arrive. Almost every operator offers free cancellation up to 24 hours before departure, so there is no practical reason to delay booking in favor of the flexibility of waiting.
We’ve put together a full seasonal breakdown in our best time to visit Mykonos tours guide so you know exactly when to go based on your priorities, budget, and tolerance for tourist crowds.
Questions before you book? The Mykonos Tours team can recommend the right tour for your group size, travel dates, and what you want from the day.
Yes, consistently. Among the travelers we work with, boat tours have the highest rate of post-trip recommendation of any activity on the island. Seeing Mykonos from the water, reaching coves not accessible from land, and combining the Delos archaeological site with swimming at Rhenia makes for a complete and distinct day that beach and nightlife alone cannot replicate. Most travelers who almost skipped a boat tour say afterward it was a highlight of the trip.
Semi-private group catamaran tours run €90-180 per person for a half-day or full-day tour including food and drinks. Guided Delos and Rhenia cruises run similarly, around €90-140 per person. Private half-day speedboat or RIB charters start around €800 per boat for up to eight passengers. Private catamaran charters for a full day start around €1,600. All prices are as of June 2026 and vary by operator, vessel size, and season.
Delos is a UNESCO World Heritage archaeological site six miles southwest of Mykonos: the mythological birthplace of Apollo, a former ancient trading center, and one of the most significant ruins in the Aegean. Boat tours from Mykonos reach it in 30-40 minutes. The public ferry from the old port costs around €25 round trip; entry to the site is €20 separately. A guided tour combining the boat, entry, and a licensed archaeologist runs €90-140 per person and is strongly recommended, as the ruins require expert context to read properly.
Morning departures for Delos and Rhenia cruises have the calmest conditions before the meltemi builds through the afternoon, and Delos is more bearable before the midday heat. Late afternoon departures for sunset tours give the best light of the day from the water. The slot to avoid is midday in peak July and August, when the meltemi is at its strongest and the open-water crossing to Delos is at its roughest.
By boat from the old port in Mykonos Town. Public ferry boats run from around 9am, with returns typically at noon, 1:30pm, and 3pm. In peak season, check the chalkboard at the old port ticket office for that day’s exact schedule. The crossing takes 30-40 minutes. Alternatively, organized tours depart from Ornos Bay by catamaran and include the Delos visit as part of a longer day combining Rhenia swimming and on-board lunch.
Yes. Strong meltemi winds in July and August can cause operators to alter routes or, in extreme cases, cancel tours. Most reputable operators offer a sheltered south-coast alternative itinerary on windy days rather than cancelling outright. Full cancellations typically trigger a full refund or rebooking option. Check the operator’s wind policy before booking, and if you are prone to seasickness, confirm the planned route for your specific date in advance.
