A day on the water with two big Mykonos hits.

I love how this cruise mixes a stop at Rhenia for a swim with a guided UNESCO tour of Delos, so you get both sea time and real archaeology without rushing around town. The lunch-and-wine setup onboard is practical, and the free Wi‑Fi is handy when your phone starts acting dramatic at sea. One consideration: Delos admission isn’t included, and your time on the island is limited to about 1h30 with the guide, so plan for a structured visit rather than a long, wandering day.

What also makes this feel like good value is the small-group yacht format: it tops out at 35 people, and the experience is run with proper safety briefings and crew support. In the Delos portion, English guidance seems to hit the mark—names like Fanny, Silia, and Elisa show up in the feedback as guides who make the ruins easier to picture. And yes, the ride can be bumpy in wind, so I treat this as a sailing day first, even when you’re mainly here for Delos.

Key highlights worth clocking before you go

• Rhenia swim-and-snorkel break in a quiet cove with gear and floating noodles included
• Licensed English guide at Delos for temples, marketplaces, and museum artifacts
• Onboard lunch plus house wine and drinks served between swims and ruins
• Free Wi‑Fi on the yacht so you’re not totally offline at sea
• Max 35 people which can keep the day from feeling like a bus tour

Getting on board at Mykonos: the sailing part is real

This tour starts at the yacht, with a representative briefing you on what the day looks like and getting you matched up with the crew. Before you pull away, there’s a safety talk, which matters here because the Aegean can turn from calm to choppy pretty fast.

If you want hands-on fun, you can help raise the sails or get a short steering lesson. Even if you don’t, I like that you’re not just sitting there—your day is actively shaped by sailing, sun, and movement. One review noted the ride can get chilly and rough, and another specifically warned that wind can make things bouncy. If you’re prone to motion sickness, I’d take precautions before you board (a quick dose of dramamine is a common approach people use), and stay toward the center of the boat if you have a choice.

Timing-wise, the start is 9:00 am. Weather matters a lot in Mykonos, and the operator is clear that the experience requires good conditions—so have at least one flexible day in your schedule when you can.

Rhenia Island: the swim stop most people actually remember

After about an hour of sailing, you anchor in an unspoiled bay at Rhenia. The point here is simple: a golden-sand cove, clear water, and time to get in. You swim directly from the yacht using the ladder—there’s no tendering or shore dock described for this stop—so you’re committing to swim-first time rather than beach-walking.

Snorkeling equipment is included for free: mask, snorkel, and fins, plus floating noodles. That’s great because you don’t need to bring gear or rent it in town. Do note a practical detail from the setup: this is a swimming and snorkeling break, but it’s not billed like a reef safari. If you like calm, clear water and don’t mind that the underwater scene may be basic, you’ll likely be happy. People also mention that the water can feel chilly, so if you’re sensitive, keep your swim time realistic.

Also, check your towel situation. Beach towels aren’t included, but they can be rented onboard. If you prefer a familiar towel, bring one—your future self will thank you, especially after a direct-from-the-boat swim.

This is also where the day turns into a social, easy-going rhythm. You’re not grinding through ruins yet. You’re in the sun, surrounded by sea color, and getting fed in a relaxed way before Delos.

Lunch and drinks onboard: simple, filling, and good enough

Right after the water time, lunch is served onboard. The menu is designed for a boat day, so think “solid fuel,” not “fine dining.” You’ll get either:

• Italian pasta with Greek-flavored dressing and Greek salad, or
• a local Mediterranean-style buffet with fresh local fruits

On the drinks side, the cruise includes house wine (white and rosé), soft drinks, bottled water, and instant coffee/tea. That’s a big part of the value: you’re paying for the boat, and you’re not separately paying for lunch or drinks while you’re out of Mykonos.

One helpful practical note: the drinks are complimentary, but on a boat, service can mean you may need to ask rather than assuming it will just be poured. If you want wine or a soda, just make eye contact and request it. Crew support is part of how these tours stay smooth.

If you’re picky about carbs, temper expectations a bit—some feedback described the meal as carb-heavy. Still, it’s a good reset after swimming, and it saves you from spending time hunting for food in Mykonos before your archaeology stop.

Delos UNESCO: what you’ll see with the guided route

Delos is the mythic birthplace of Apollo in Greek mythology, and in real-world terms it’s a UNESCO-listed site tied to an ancient trading and pilgrimage city. After Rhenia, you go ashore for a licensed guided tour (entry fee not included) that runs about 1h30.

Here’s what makes the guided time worthwhile: Delos isn’t just a collection of rocks. Your guide helps connect the dots between what you’re standing on—temples, marketplaces, and sacred sites—and the bigger story of how this place functioned.

You’ll also have museum time with artifacts, which is a smart move. Ruins can be hard to fully understand when you’re looking at stones under harsh sun. A museum stop gives context, and the artifacts make the ruins more than just shapes and walls.

Then there’s the walk up Mt. Kythnos for views. You’re getting a “see it from above” moment that’s hard to recreate on your own. But it does mean you need a moderate level of fitness. If you’re dealing with mobility limits or you’re traveling with pregnancy concerns, the operator asks you to advise before booking so they can reconfirm safe participation.

One more Delos reality check: your ground time is limited. Some people wish they’d had more time to wander, so if you’re the type who likes to linger and sketch and read every plaque, you might feel a bit rushed. This tour works best when you’re happy with a structured route and you’re willing to let the guide set the pace.

On-deck comfort, Wi‑Fi, and the “will I be cold?” question

Boats have their own weather rules. Even when the air feels warm, wind and sea spray can make it cooler on deck. People specifically mention chilly water and windy conditions, plus the occasional bumpy ride. Pack like you’ll be outside for hours: sun protection, layers if you run cold, and a plan for wet spray.

The tour includes free Wi‑Fi onboard. That’s genuinely useful in Mykonos because you’ll likely want maps, messaging, or sharing photos while you’re still close to signal. Just don’t expect it to behave like your home Wi‑Fi—use it for practical stuff, not streaming your entire week.

Also included are all safety equipment and fuel charges and taxes. You’re not nickel-and-dimed mid-day for the essentials.

For the Delos guided portion, a wireless radio device is not stated as included by default. It’s described as complimentary if provided, and there may be fees if it isn’t or if it’s lost/damaged. Translation: if you’re sensitive to hearing loss in outdoor spaces, ask about the radio device before you start the inland portion so you’re not guessing.

Price and value: what you get for about $145

At $145.12 per person for roughly 6 hours, you’re paying for a full yacht day with real content. The included items that actually move the needle are:

• Sailing yacht cruise for about 6 hours with crew
• Licensed English guide at Delos
• Lunch onboard
• House wine, soft drinks, bottled water, and coffee/tea
• Snorkeling gear (mask/snorkel/fins) and floating noodles
• Free onboard Wi‑Fi
• Farewell shot drink
• Safety equipment, fuel, and taxes

The big exclusions are the Delos entrance fee (paid on site by cash) and optional pickup/drop-off shuttle service. Those add-ons matter because the Delos ticket can change your true “all-in” number.

Still, I think the price is competitive for what you get: you’re not just seeing one place. You get a sea swim stop, a UNESCO site with a guide, food and drinks, and a sail back to Mykonos that functions like a built-in decompression period.

Where value can slip is comfort level. This tour is capped at 35, but boat assignments can vary, and some groups have been smaller (around 8) while others have felt larger (around 14). If you really hate sharing space, you’ll want to read the room when you board and don’t assume “small group” means “empty deck.”

Who should book this Delos and Rhenia sailing cruise

I’d steer you toward this tour if you want a day that’s:

• Equal parts archaeology and sea time
• Guided enough that you understand what you’re seeing at Delos
• Easy on planning, with lunch and drinks handled onboard
• A good fit for short stays in Mykonos, especially since the operator recommends scheduling early in your trip in case weather forces changes

I’d think twice if you:

• Need a lot of free wandering time at Delos (your guided time is about 1h30)
• Get strongly seasick in wind and chop
• Have mobility challenges and didn’t disclose them when booking (Delos includes walking, including a climb toward Mt. Kythnos)

The overall vibe can work for families too. One review highlighted how the crew handled a 3-year-old kindly, but as always, safety comes first on boats, so keep kids close and follow crew instructions.

Booking smart in Mykonos: practical tips that save stress

This is one of those tours where good prep makes the day feel effortless.

• Plan to be at the meeting point on time: start at Olia Hotel Mykonosparalia in Mykonos, and you’ll identify staff by a Sunfos Alessia Yachting shirt or sign.
• Expect the disembarkation point to potentially change because of weather. That’s normal on sailing days.
• Bring cash for Delos entrance because the entry fee is payable by cash on site.
• Consider sunglasses, sun hat, and sunscreen. Delos is sunny, and you’ll be outside for the ruins and viewpoint walk.
• If you want pickup, it’s optional and costs extra. The meeting area is noted as near public transportation, so door-to-door may not be worth it unless your schedule or mobility makes it necessary.
• After booking, you may be asked for passport details (full name, passport number, nationality, date of birth) for the passenger list before embarkation.

And one last sailing-day mindset: pack for wind as if it’s always possible. Even on a good day, sea spray and breezes are part of the experience.

Should you book this sailing cruise to Delos and Rhenia?

Yes, if you’re aiming for one high-impact day: swim in clear Aegean water at Rhenia, then get a guided UNESCO visit at Delos with museum time and a viewpoint walk. The included lunch, house wine, snorkeling gear, and onboard Wi‑Fi make it feel like a complete package rather than a “tour plus extra shopping.”

I’d hold back if you want long, unstructured time at Delos, if you’re very sensitive to motion, or if you’re allergic to paying extra on the spot (Delos entrance is cash-based). But for most people balancing history and beach time, this is the kind of Mykonos day that saves you from choosing between sea and ruins.
