Two islands, one boat, and zero wasted time. I like this trip most for the combo of Delos ruins and Rhenia’s swim stops, because you get history plus beach time in one half-day. One thing to consider: Delos is often hot and exposed, and the Delos entrance fee is extra.

On the water, I also love the energy. The family-run crew turns the return ride into a music-and-dance scene, and the included BBQ with fruit hits the spot after time in the sun and sea.

Key highlights I’d prioritize

• UNESCO Delos (self-guided for about 2 hours): walk among major ruins at your own pace
• Rhenia swim time (about 3 hours): jump in for swimming and snorkel with clear water
• BBQ lunch onboard: meat skewers, salad, rice, and fruit get served during the Rhenia stop
• Cycladic Sisters by boat: you ride the coastline views between islands for the whole experience
• Crew-led fun on the return trip: singing, dancing, and good vibes on the way back

Why Delos and Rhenia in one half-day feels so right

This is the kind of Mykonos outing that fixes a common problem: you either pick “history all day” or “beach all day.” Here, you get both. You sail out from Mykonos, spend solid time in the water at Rhenia, then switch gears to Delos, one of Greece’s most important archaeological sites.

The best part for most people is that you control the balance. At Rhenia, you’re there long enough to swim, snorkel, and just float. At Delos, you get a structured window (about two hours) that’s long enough to see the big spreads of ruins without feeling like you need a whole day of museum stamina.

And yes, the mood helps. Reviews consistently mention a lively crew and a return ride that leans into music and dancing, so this doesn’t feel like a rigid bus tour.

Price and what $101 really buys (plus the real add-ons)

At about $101 per person for a 6.5-hour outing, you’re mostly paying for the boat logistics: getting to Delos and Rhenia, fuel, crew, and the onboard meal. The tour includes the boat trip and the BBQ plus fruit, so you’re not stuck looking for food at sea.

Two costs you should mentally plan for:

• Delos entrance fee is not included (approx €20).
• Snorkeling equipment is not included, and you can purchase it onboard.

Also, understand the “value” angle: you’re paying for convenience and time. A private boat or separate ferry-and-taxi approach can balloon fast, and Delos in particular is easiest when everything is coordinated for you.

Old Port meeting point: the quick way to avoid stress

You meet at the bus station at the Old Port of Mykonos. That’s a good setup for most people because you’re already near the main harbor area where boats and tours organize.

My practical tip: arrive a little early. One recent guest said it took extra time to locate their agent because signage wasn’t obvious. When you’re dealing with a busy port, that extra buffer can save your whole morning.

Bring your ID/passport. The activity lists passport or ID card as what you need, and you’ll want it ready at check-in.

Rhenia Island: the swim stop that makes this trip

Rhenia is the part that makes people say they can’t believe the water. The schedule gives you roughly three hours there, and the activity is built around water time: swimming and snorkel, plus a BBQ meal while you’re onboard.

What you’ll actually do in the Rhenia window

A typical flow looks like this:

• You sail over from Mykonos (about 45 minutes).
• You get time to swim and snorkel in clear water.
• The BBQ lunch and drinks arrive during the stop.
• You return onboard when it’s time to head for Delos.

From guest notes, the entry is often from a boat stop near the shoreline, so it’s usually more practical for confident swimmers. One review also flagged that the water entry can mean stepping in and getting back to the boat, so if you’re unsure about swimming, plan on taking it slow.

Water shoes are smart

A couple of comments mention a rocky shoreline near the beach area. If you want easier footing, water shoes help.

Sea-sickness check

The boat ride can be a bit choppy. One guest even said bring meds if you need them. If you’re sensitive to motion, pack your usual remedy and keep that in mind before boarding.

The BBQ lunch: more than just a snack

Multiple reviews called the food good, and several mentioned specifics like meat skewers, chicken/pork sticks, Greek salad, rice, watermelon, and plenty of drinks. Even if you’re not a wine person, it’s a useful way to refuel after swimming.

So in your head, don’t think of this as a “quick sandwich lunch.” Think of it as fueling a day outdoors.

Delos UNESCO ruins: how to get the most from two hot hours

Delos is the archaeological payoff. You’re given about two hours for a self-guided visit, and Delos is a UNESCO World Heritage Site.

This self-guided format is important. A guide for Delos is not included, so you’ll rely on the site’s plaques, a map, and your own choices. That can be great if you like moving at your own pace. It can also feel like work if you want a deep narration.

Plan your walking strategy

Delos has a lot to see, and it’s famously exposed in the sun. One guest warned that the hottest part of the day can make walking tough, with little shade. That means you’ll get more enjoyment if you bring:

• sunscreen
• a hat
• water

If you feel yourself slowing down, prioritize the main highlights and don’t try to cover every corner. Two hours goes fast once you’re actually walking among the ruins.

Can you stay onboard instead?

Yes. The plan allows you to stay on board if you’d rather swim again or just rest. Several reviews also say there’s an option to do either Delos or an extra swim stop. If you’re traveling with friends who want different things, this flexibility can keep everyone happier.

When Delos access gets limited

One review mentioned Delos was closed early due to heat on that day, and the itinerary shifted to give more time to swim/relax. That’s not something you can count on, but it’s a real-world reminder: summer weather can change the plan fast. Keep your expectations flexible.

Sailing between islands: the scenery time you tend to forget

The sailing segments aren’t just travel. You’re moving across the South Aegean and getting that in-between view of the Cycladic Sisters by boat. Even when the water is choppy, it’s still part of the charm: you’re not stuck indoors, and you’re constantly passing coastline and island silhouettes.

Also, note the boat setup. One guest described it as a big, heavy boat that handled choppy waters. Another said the ride can feel rocky, which is why motion-sickness planning matters. Either way, you’re not on a tiny craft, which is reassuring for a lot of people.

The return ride: where the dancing comes in

This tour has a reputation for ending with fun. Multiple guests mention a return trip with music and a dance party. Reviews describe singing and dancing, and at least one guest said the hosts provided a fun time with dancing at the end.

If you’re into social energy, you’ll likely enjoy it. If you’re not, you can still stay seated, but the vibe is part of the overall experience.

Crew personalities you might notice

Names that came up in recent reviews include Mola, Mohamed, Michael, and Poala. It sounds like this is the kind of operation where the crew interacts with passengers throughout the day, not just at check-in.

What to pack for a smooth Delos and Rhenia day

You’ll be outside all day: sea time, sun, and walking ruins. Don’t show up with “just a swimsuit” and hope. Here’s what makes the day easier, based on what people flagged and what the schedule demands:

• Swimsuit and a quick-dry towel (you’ll get in the water at Rhenia)
• Sunscreen and a hat (Delos is exposed)
• Water shoes (if you want easier footing on rocky areas)
• Passport or ID card
• A refillable water bottle (Delos has no shops)
• Any sea-sickness meds if you’re prone to motion feeling

Snorkeling gear isn’t included, but you can buy it onboard. If you snorkel often and want your own setup, you might prefer to bring your own. If you’re trying it for the first time, buying onboard can work since you’re already there.

Who this trip suits best (and who should rethink it)

This is a strong match if you want a single, organized outing that gives you:

• major ruins at Delos without needing a full-day commitment
• serious water time at Rhenia
• a social, friendly crew vibe

It’s also good for mixed groups because Delos is optional in the sense that you can stay onboard instead, depending on how you want to spend your time.

You might not love it if…

• You hate boats in choppy water. The schedule requires sailing, and the ride can feel rocky.
• You want a guided deep history lecture at Delos. The Delos portion is self-guided, and a Delos guide isn’t included.
• You want a lot of shade on a walking-heavy site. Delos is exposed and hot in summer.

Should you book this Mykonos to Delos and Rhenia boat trip?

I think it’s a yes for most people who are doing Mykonos and want more than just beach hopping. The value is in the mix: boat transport + BBQ + real Delos time + Rhenia swimming in about 6.5 hours.

Book it if:

• you care about UNESCO ruins but don’t want to lose the day to museums
• you’d rather spend a chunk of time in the water than just looking from shore
• you enjoy friendly group energy, especially on the return ride

Skip or reconsider if:

• you get seasick easily and don’t want to prepare for choppy sailing
• you need a dedicated Delos guide explanation
• you’re not comfortable with an exposed, hot walking site

If you’re on the fence, the deciding factor is simple: do you want Delos plus Rhenia in one day? If yes, this is one of the most efficient ways to do it from Mykonos.
