A speedboat day in the Aegean hits different. This private Delos-to-Mykonos cruise strings together myth-stuffed ruins, a swimming paradise at Rhenia, and then a Greek sunset return ride that feels made for photos. You’ll spend most of the day on the water, with a captain guiding you between small ports and well-known south-coast beach stops.

Two things I really like about this experience: the open bar setup (beer, wine, and soft drinks are free on board) plus snorkeling gear if you want to slip in for a look under the surface. I also appreciate that Delos is treated with respect, even if you’re mostly viewing it from the water first.

One consideration: the day includes Delos viewpoints, but the Delos archaeological-site entrance fee is not included, so plan for that if you want to go beyond what you see from the boat.

Key highlights at a glance

• Private group for up to 9: you control the pace and you’re not sharing the boat with strangers.
• Beer, wine, and soft drinks included on board, with bottled water and snacks.
• Snorkeling equipment provided, so you can add a swim whenever conditions look good.
• Rhenia swim time is the main event, especially near Skinos (often nicknamed Blue Lacuna).
• Aegean sunset ride back to Mykonos: the timing tends to give you the most memorable light.

Why this Delos–Rhenia–Mykonos route works so well

This cruise is designed for one big goal: to compress the best of the region into one day without turning it into a long ferry-and-bus marathon. You start in Mykonos, then go straight to Delos, where you get that instant sense of place just by approaching the island’s small port and seeing the ancient monuments.

Then you switch from history mode to beach mode. Rhenia is close by, and it’s where the water time really pays off. After that, the south-coast Mykonos stops keep the vibe relaxed: you’re mostly using the boat as your transport to hop between shoreline viewpoints, beach areas, and the sort of places that people talk about for their sea access.

It’s also a practical setup for groups. The price is per group up to 9, and the boat day is long enough (about 8 hours) that you’ll feel you actually used your time well.

Ornos dock to Delos: holy island views, and the one fee to know

The day starts at Ornos dock with an approx. 10:00 am departure, and Delos is the first stop. The boat trip is short enough that you don’t feel rushed before you arrive. Once you’re at Delos, you can see the ancient monuments from the small port area, and the island’s mythology is the theme of the moment—Poseidon revealing the holy island, and Leto arriving to give birth to Apollo and Artemis.

Here’s the key practical detail: the Delos archaeological-site entrance fee is excluded (listed as 12 euro per adult). The cruise can give you a meaningful view and a quick look, but if you want to go inside the archaeological area in a more formal way, you’ll need to account for that extra cost.

My tip: if you’re the type who wants to walk among ruins for longer than a quick look, budget the ticket early in your planning so it doesn’t surprise you later. If you’re more into the sea views and photos, you can treat Delos as the dramatic opening act.

Rhenia and Skinos (Blue Lacuna): the best swimming stretch

After Delos, you head to Rhenia, the nearby island that’s famous for clear water and quiet beach time. Historically, this island has a darker reputation: in antiquity, people were sent away from Delos—births and deaths were restricted there—and Rhenia became a sort of necropolis and sanatorium. Today, though, you’re there for the contrast: calm water, beaches, and a long swim-friendly break.

You’ll have about 3 hours at Rhenia, and this is the stop where the day usually turns into a full reset. The most famous beach is identified as Skinos, often called Blue Lacuna. You’ll be able to swim in the crystal-clear water, sunbathe on the sandy shore, stroll along the coast, and generally take your time.

A couple things to keep in mind:

• You’re on a speedboat cruise, so you’ll want to be ready to go when it’s time to re-board.
• The snorkeling gear is included, so this is where you’re most likely to actually use it.

If you want a “spend the day in swim-and-sun mode” experience, Rhenia is why you book this route.

South Mykonos beach-hopping: Psarou, Elia, and Kalo Livadi from the sea

Once the Rhenia swim break is done, the cruise shifts to the south coastline of Mykonos. You’ll stop in areas that are tied to the island’s international beach reputation—places people associate with beach bars, restaurants, and sea-entry access.

The stops listed include:

• Psarou beach (about 1 hour)
• Elia Beach (about 1 hour)
• Kalo Livadi Beach (about 1 hour)

This part of the day isn’t just “pass by the coast.” You’ll be getting that sea-level perspective—one of the best ways to appreciate Mykonos south because cliffs, coves, and beach shapes show up differently from the water than from shore.

One more useful context: the cruise notes sea-entry access by private docks at the most famous spots. In plain terms, this is a day where your boat ride is what gets you close to the action, while still giving you enough onboard downtime to relax.

My take on the tradeoff: these stops are shorter than Rhenia, so treat them like picture windows plus a chance to cool off, not like a full beach club day. If you’re hoping for hours of walking, plan to focus on views, quick swims, and short breaks.

Open bar, snacks, snorkeling gear: what’s included and what to double-check

This is one of those days where “included” can mean a few different things, so it helps to be precise. Based on what’s provided, you should expect:

• Unlimited beer, wine, and soft drinks on board
• Bottled water
• Snacks and fresh fruits
• Snorkeling equipment included
• A captain included

The open bar part is pretty straightforward on paper: beer, wine, and soft drinks are free of charge on board. Still, one caution comes from the way these kinds of cruise days can be interpreted in the real world. There was at least one issue tied to what a guest expected versus what was offered during the day, so the smartest move is to set your expectations clearly in advance—especially if you’re picturing a full bar setup with many spirits or no limits at all.

Also, snacks are included, but don’t plan on this replacing lunch. Think of snacks as a convenient add-on for the boat ride and beach breaks, not a full meal.

On the snorkeling side, this is a real perk because you don’t have to rent gear at an extra place. If you’re new to snorkeling, Rhenia is a logical place to try it, since conditions are described as crystal-clear and beach access is right there.

Timing, private-group comfort, and practical tips for 8 hours

This is an 8-hour cruise with an early-ish start (10:00 am). That matters, because it gives you time to do Delos first, then get to the best water stop before the day gets too hot. You’re also set up for the classic “light changes” moment—coming back to Mykonos with sunset views.

Because it’s private (your group only, up to 9), the day feels more flexible than most multi-stop boat tours. You can keep conversations going without noise from a large crowd, and you’re not trapped on a set schedule in the way you would be with bigger group operations.

Practical advice that will make your day smoother:

• Bring swim gear you’re comfortable re-using quickly. You’ll likely go back and forth between deck time and water time.
• Plan for sun. You’ll be out on the boat and at beaches for hours.
• If you’re sensitive to heat or glare, bring sunglasses and something for your face (cap or sunscreen).
• If you’re set on Delos as more than a viewing stop, budget the 12 euro per adult entrance fee so you can decide without stress.

One more planning note: this experience is often booked well ahead—on average 122 days. If your dates are firm, book early rather than waiting for last-minute deals.

Price and value: $1,982 per group, and how to judge if it fits you

The price is $1,982.41 per group (up to 9) for roughly 8 hours. That sounds steep until you do the math with the key idea: you’re paying for a private boat day, not a per-person ticket on a shared tour.

If your group fills closer to 9 people, you can think of it as roughly a couple hundred dollars per person. If you’re traveling with fewer people, the cost per person climbs quickly, and then this becomes a “worth it if you value privacy and time on the water” choice.

So how do you decide?

• If your top priority is Delos + Rhenia + south-coast Mykonos in one go, and you want control of the day, the group pricing can be fair.
• If you only care about one beach stop, you might get better value with something shorter or more focused.
• If your group includes snorkelers and you want gear included, that’s a small cost you avoid.

Also factor in what’s actually included: snacks, bottled water, fresh fruits, snorkeling gear, fuel surcharge, and the captain. Those add up more than they look like on a menu of extras.

Who this private speedboat cruise is best for

I’d point this cruise toward travelers who want a classic Mykonos day without the hassle of hopping between ferries and buses. It’s especially good if you:

• Want one boat day that covers Delos viewpoints, a major swimming island, and multiple south-beach areas
• Prefer private-group comfort over crowded tours
• Want snorkeling gear included and you’re willing to use it on the best water stop

It’s also a solid fit for mixed groups—people who want history can enjoy Delos, and people who want beach time can focus on Rhenia and quick swims during south-coast stops.

Should you book this Delos, Rhenia and Mykonos private cruise?

If your idea of an ideal Mykonos vacation is time on the water with a little bit of everything—ruins, swimming, and sunset—then this is an easy yes to consider. Rhenia is the anchor, and the cruise gives you a practical way to reach it with a long swim block.

I’d book it if:

• You have a group and can use the up-to-9 pricing
• You care about snorkeling with included gear
• You’re okay with Delos being a shorter stop unless you pay for site entry

I’d think twice if:

• You’re expecting a full lunch experience on board or a wide-ranging bar beyond beer, wine, and soft drinks
• You’re traveling solo or with just a couple of people and privacy alone isn’t worth the per-person cost

If you match the vibe—sea time, short hops, and a sunset return—this is one of the better ways to see more of the area in a single day.
