A day on the water between Delos and Rhenia is a strong combo. You get UNESCO sights at Delos, then you switch gears to calm, sandy coves on the uninhabited island of Rhenia. I love the way this trip mixes two very different Aegean experiences without wasting half your day in transit.

I especially like the built-in flexibility at Delos: you can stay on board for swimming and views, or hop off for a 2-hour Delos exploration with the right pacing for the site. One thing to keep in mind is that Delos entrance fees and an on-site guide are not included, so your final cost can creep up if you plan to do the full Delos visit.

Key things to know before you go

• UNESCO Delos time (2-hour option): you’ll have a defined window to see the ancient remains.
• Swim either on the cruise or after Delos: you can stay aboard or disembark at Delos depending on your mood.
• Rhenia’s payoff is the beaches: expect uncrowded coves and clear water more than landmarks.
• Lunch and drinks are included: makes the price feel more fair on a 6.5-hour day.
• Passport info has a strict timing rule: send it at least 12 hours before departure.
• Cold weather can happen: an extra layer can save your comfort, especially early.

A short cruise that hits Delos and Rhenia in one go

This is the kind of cruise that works when you want variety but still have only one day in the Cyclades. Delos gives you the big-name ancient site energy. Then Rhenia shifts you into beach-mode, where the main event is clear water, sandy coves, and getting away from crowds.

If you like your Greece days to feel active without being stressful, this one fits. You’re not stuck on a bus all afternoon. You’re moving by sea, which also means the views keep changing, from Mykonos’s harbor bustle to open-water stretches and then calmer island scenery.

Getting to the boat: Mykonos New Port and passport timing

The meeting point is at the New Port of Mykonos, right opposite the Olia Hotel. Plan to arrive early enough to handle check-in without rushing. This is one of those tours where a little timing buffer buys you a calmer start.

Also, read the passport rule carefully. Your passport information must be sent at least 12 hours before the cruise so port authorities can allow you to board. That’s not optional. If you’re traveling with a last-minute document change or you’re slow with emails, build that time into your plan.

Bring your passport or ID card. The cruise is 6.5 hours total, so once you’re late, it’s hard to make up time.

Delos, the UNESCO stop: how the choice works and what to focus on

Delos is the star of the ancient side of this day. The cruise includes time at this UNESCO world heritage site, but how you experience it depends on your choice during the Delos stop.

You have two ways to do Delos:

• Stay on board and enjoy the blue and green water from the cruise.
• Disembark for a 2-hour Delos tour.

That split matters. If you’re the type who wants to move at your own pace through ruins, staying onboard can be a real win. You avoid the pressure of keeping up with a group on uneven ground.

If you want the full impact of seeing the site on foot, the 2-hour window is the practical target. You’ll want to arrive with a quick mental checklist. In a short tour like this, you’ll get the most satisfaction by deciding in advance what you care about—main archaeological areas, key structures, and general layout—then let the guide’s commentary fill in the gaps.

One important cost note: Delos entrance fees are not included. Also, an English (or other language) speaking guide for Ancient Delos is not included either. The cruise itself has a live tour guide (English, Greek), but the site tour needs to be handled within what’s offered by the operator and what you pay on top for entry.

On-board swimming during the Delos stop: a smart way to enjoy the Aegean

Even if you do the Delos tour, you’ll likely appreciate the chance to get back on the water. During the Delos portion, you can enjoy swimming from the boat in the blue and green waters.

This is where the cruise format pays off. Delos can be visually intense—stone, mosaics, and ruins in a concentrated time. A swim break gives your body a reset, and it also changes how you experience the island setting. Salt air and open-water light are part of the Delos atmosphere, even if your feet are on deck.

Practical tip: bring swim basics that you can use fast. A small towel, something to keep your phone dry, and a cover-up help. If the morning is cool, you might also want a layer for when you get back on board.

Rhenia Island’s real trick: sand, coves, and clear water

Rhenia is the reason many people pick this cruise. It’s uninhabited, and the appeal is physical: sandy coves, crystal clear water, and beaches that feel uncrowded compared with more developed spots.

The cruise sails straight to Rhenia after Delos, and that direct transfer is part of the value. You’re not losing the day with long logistics—just switching from ruins to swim time.

Once you’re there, the choices are simple:

• Swim
• Snorkel
• Disembark if the schedule allows for the main beach time

When an itinerary highlights snorkeling and crystal water, take it literally. Plan your time so you can spend at least a chunk of it in the water, not just on the deck looking at it. If you’re the kind of person who enjoys a slow pace—floating, checking out the shoreline from the shallows, then repeating—you’ll probably feel like you got more out of Rhenia than you expected.

Lunch, drinks, and what you’re really paying for

At $117 per person for a 6.5-hour outing, the big question is: what’s included, and what costs extra?

Here’s what’s covered:

• Cruise escort
• Lunch on board
• Drinks and beverages
• All local taxes

So you’re not funding a meal on top of the ticket, which matters on an island day where food lines and prices can add up quickly.

What’s not included:

• Delos entrance fees
• A speaking guide/escort specifically for Ancient Delos (language options are listed, but not included)
• Land transfer services (listed as 8€ per person, per way)

This pricing structure makes sense if you’re okay paying separately for Delos entry. It’s also fair if you view the Delos part as an option with an extra fee rather than a guaranteed full guided experience.

The guide and language situation: English and Greek on the water

The cruise includes a live tour guide in English and Greek. That’s useful for helping you understand what you’re seeing while sailing and while moving through the day.

But remember: the information about Delos notes that an English (or other language) speaking guide/escort for the UNESCO site is not included. So if your priority is a fully guided Delos walking experience in English, budget for how that’s handled during the tour option you choose.

A simple way to handle this: when you check in, ask what exact Delos option you’ll be doing and what is covered with your ticket versus what costs extra onsite.

Weather, timing, and small surprises: how to protect your day

Aegean weather can turn fast, and this matters most during the Delos portion because you’re deciding whether to get off the boat and walk around.

One clear pattern from real experiences: operators can be patient when conditions are rough early. In at least one case, the weather was cold and rainy at the start, and the team waited for things to improve so people could explore Delos at their own pace. That’s exactly what you want to hear—flexibility, not stubborn schedules.

Still, timing can shift. A couple of experiences point to misunderstandings about what time is spent on Delos versus whether Rhenia time happens as expected. You can’t control the day’s anchor decisions or docking logistics, but you can reduce the chance of feeling shorted by doing two things:

• Ask at check-in how the day’s order will run and how much time you have at each stop.
• If Rhenia beach time is a top priority, confirm the plan for disembarking there and whether there are any conditions that could change it.

Also, if you’re prone to feeling cold, pack for it. Even in Greece, mornings can feel sharp when you’re moving on deck.

Who this cruise suits best (and who might feel frustrated)

This cruise is a great match if you want:

• An efficient day that covers Delos + Rhenia
• A relaxed rhythm: ruins, then sea time, then return
• The chance to swim and snorkel with minimal extra planning

It’s also a decent family option because it’s straightforward: you’re on a boat, food is handled, and you’re not navigating multiple ferry connections.

It may disappoint you if you’re extremely Delos-focused and want a long, unhurried, fully guided walking tour. The Delos exploration is described as a 2-hour option, and if your expectations are bigger than that, you might feel like the time is tight. It can also be frustrating if your ideal day includes guaranteed full beach time at Rhenia no matter what the weather does—because operations can change what’s practical on the day.

Service you can feel: helpful staff makes a difference

A strong theme in the good experiences is human service. One person described forgetting a jacket and being able to use one of the crew’s items when the weather turned chilly. That kind of small, practical kindness matters on a sea day when comfort can change fast.

There are also specific names attached to a standout interaction: Joana and Kristo. When people feel supported—especially during weather delays or when timing gets complicated—that tends to turn a potentially awkward day into a memorable one.

Should you book this cruise to Delos and Rhenia?

I’d book it if your idea of a perfect Mykonos day is: see one major ancient site, then spend real time in clear water on an uninhabited island. You’ll likely feel good value because lunch and drinks are included, and the day is short enough that you’re not drained by travel.

I’d think twice if you’re planning to spend all your time obsessing over Delos details and need a long, fully guided UNESCO experience. This tour is built for a “see it, enjoy it, then swim” rhythm.

If you decide to go, do these two things and you’ll stack the odds in your favor:

• Send your passport details at least 12 hours before departure.
• Ask at check-in how the stop times will work that day, especially if Rhenia beach time is your main goal.
