Mykonos from the water hits different. This small-group catamaran day mixes Delos UNESCO scenery from the sea with long, relaxed time at Rhenia’s calm, swimmable coves—plus real onboard comfort like snorkeling gear and lunch with unlimited drinks.

Two things I genuinely like: the pacing feels easy (you’re not racing around), and the vibe is social without being chaotic, thanks to a maximum of 10 travelers and a skipper/crew that run a tight, friendly ship. The BBQ lunch and local wine/beer also matter more than you’d think on a boat day—they keep you fueled while you’re out in the Aegean sun.

One drawback to keep in mind: this is weather-dependent, so if conditions aren’t good, the operator may switch dates or cancel. And you’ll pass Delos rather than visit it onshore, so if you’re hoping for museum time on the island, plan for something else.

Key Things You’ll Notice on This Catamaran Day

• Small group size (up to 10): more space, less waiting, and an easier feel for families, couples, and friends.
• Delos insights while cruising by: you get context about Apollo and Artemis without the logistics of landing.
• Rhenia’s long water-time (about 4 hours): enough hours to swim, snorkel, and actually relax.
• Snorkeling gear included: masks and snorkels are provided, so you can travel lighter.
• Unlimited local wine and beers: the drinks are part of the day, not an add-on.
• SUP only if weather allows: paddle time might happen, but don’t count on it if winds are up.

Meeting at Agios Ioannis Diakoftis: The Start That Sets the Mood

You start at Agios Ioannis Diakoftis, at the Agios Ioannis Dock in front of the church. The check-in style is straightforward—there’s a short welcome and a safety briefing, then you’re on board and moving. From the first moments, you’ll feel the difference between a big, crowded boat and a smaller catamaran outing.

Because this departure is near public transportation, you don’t need to build your whole day around taxis. Still, if you want hotel pickup, it’s optional upon request, not included automatically—so you’ll want to confirm that before you assume it exists.

One small detail I appreciate: they use a mobile ticket, which keeps things simple when you’re bouncing between beaches, wind, and sunscreen. And with WiFi onboard, you can post your first sea-shot without having to hunt for signal the entire afternoon.

Cruising Past Delos: UNESCO Views Without the On-Island Rush

You’ll cruise along the route with views of Mykonos and nearby islets, and then pass by Delos. The captain shares stories and context about Delos as a sacred UNESCO World Heritage site, including the mythological connection to Apollo and Artemis. Even if you’ve read about Delos before, seeing the coastline from the water gives the island a different feel—more immediate, more “place,” less “textbook.”

Here’s the practical part: you’re not doing a full onshore visit. There’s no mention of landing tours at Delos in your day plan—so think of Delos as a highlight you observe, photograph, and listen to, not a place you’ll explore with shoes and museum tickets.

Also, if your travel style is “I want the big sites but I hate crowds,” this approach fits nicely. You get meaningful narration without the time drain of disembarking, walking, and re-grouping.

A tip for your photos: bring sunglasses you don’t mind getting salt-sprayed and keep your camera/phone ready for quick angles. Catamaran cruising moves the viewpoint fast, and the coastline can look stunning even when you only have a few seconds.

Rhenia Island: The Best Part for Swimmers, Snorkelers, and Sail-Relaxers

Rhenia (often listed as Rineia) is the quiet-water stop. You’ll get about 4 hours there, which is a lot for a day on the sea. This is where the day shifts from sightseeing to the classic Cyclades “do less, enjoy more” mode.

On Rhenia, you can relax on board, swim, snorkel, or simply hang out in the calm. That matters because it gives you options—some people want active water time, others want shade, a cold drink, and a good book.

Snorkeling gear is included (masks and snorkels), so you’re not stuck improvising with rental shops or scrambling to find equipment at the dock. If you’ve never snorkeled before, this is one of the easiest ways to try: you’re not far from the boat, and you’re with crew support.

And yes, you may also be able to use the SUP, but only weather permitting. In other words, treat it as a bonus. If winds are calm, great. If not, you’ll still have plenty to do just by swimming and drifting in the clear water.

The On-Board Food and Drink Plan: BBQ That Actually Feels Like Lunch

A boat day lives or dies on food. Here, you get BBQ meals with chicken skewers plus local appetizers. It’s the kind of simple meal that works well onboard: something warm, filling enough, and not fussy when you’re bouncing gently over waves.

On top of that, you get unlimited local wine and beers, plus soda/pop soft drinks. For a lot of travelers, this is the difference between a “we’ll eat later” outing and a true vacation moment. You can keep the relaxed pace without needing to plan a restaurant stop afterward.

If you’re watching what you eat or you don’t drink alcohol, you’ll still be covered with soft drinks and the onboard meal. You can also pace yourself—most people are naturally calmer on a catamaran day because the sea does the entertainment job for you.

One more comfort note: because you’re out several hours, having food and drinks included keeps you from feeling rushed or under-fueled. That’s a big value point when you’re paying for a semi-private sea experience and not just a transit ride.

The Return Cruise Back to Mykonos: Panoramas on Your Way Home

After Rhenia, you cruise back toward Mykonos with panoramic Aegean views and sights of the Cyclades islands along the route. The return leg is often when the mood turns extra relaxed—people linger for photos, and conversation flows more easily once the swim/sun stress is done.

Also, keep an eye on the sky timing. Many visitors describe the return portion as the highlight, especially when the light gets softer. Even if you don’t chase sunsets on purpose, the Aegean can turn dramatic fast, and the boat perspective is made for that.

This part of the day is short compared to the main stop, but it’s still worth staying near a good viewing spot. If you’re the type who likes to watch shorelines fade into distance, this is your moment.

Group Size and Timing: Why “Max 10” Matters on a Catamaran

This tour caps at 10 travelers, and you’ll feel it. On small boats, you’re not constantly waiting for people to move, and you’re less likely to lose your spot at the rail when conditions are busy.

The tour duration is about 5 hours, so it’s long enough to feel like a proper sea day, but not so long that you burn your whole afternoon and evening. That’s useful in Mykonos, where days can disappear fast once you start hopping between beaches.

There’s also a clear structure with brief dock time at the start and end (about 15 minutes each). That makes the day easier to plan around, especially if you’re trying to keep dinner plans later. If you’re staying in or near Mykonos Town, factor in a little buffer for getting to Agios Ioannis Diakoftis for the meeting time.

What to Bring (and What You Can Skip)

Some items are not included, and this is where you can save yourself a hassle. Beach towels are not included, so bring your own (or plan to use a towel from your hotel).

Other items to consider bringing:

• Sunscreen and a hat (you’ll be outside most of the day).
• A lightweight cover-up for after swimming.
• A small dry bag for phone/keys so you’re not stressed about splashes.

You’ll also want to wear swim-friendly clothing you can handle saltwater in. Since snorkeling gear is included, you don’t need to pack a snorkel mask.

If you’re sensitive to motion, know that catamarans usually feel smoother than single-hulled boats, but you’ll still want water and a calm attitude. Having drinks included makes it easier to stay comfortable once you settle in.

Who This Tour Is Best For (and Who Might Prefer Something Else)

This is a great match if you want:

• A small-group boat day with a relaxed pace.
• Time at a swimmable island with an easy onboard setup.
• Lunch and drinks built into the plan.

It’s especially good for couples, friends, and families who want a “one big day” that doesn’t require navigating multiple boat transfers. The snorkeling included makes it beginner-friendly, and the SUP option adds a fun twist when conditions allow.

If you’re looking for a structured archaeological itinerary or an on-island Delos visit with walking routes, this likely won’t fully satisfy that itch. This day is about seeing Delos from the water, listening to the stories, and then spending your time where you can swim and snorkel.

Should You Book This Mykonos Delos and Rhenia Catamaran Tour?

If you want a high-value Mykonos outing that blends scenery, swimming time, and food without stress, I’d say book it. The small group size, included snorkeling gear, and onboard BBQ with unlimited local wine/beer make it feel like more than a simple boat ride—you’re buying comfort plus time on the water.

It’s also a smart pick if you’re trying to do “less logistics, more sea.” Meet at Agios Ioannis Diakoftis, cruise, swim at Rhenia for several hours, then enjoy the return panoramas.

The only “wait and think” moment is weather. If windy or rough conditions are forecast, you might get a date change. Also, if Delos onshore is your main priority, you may want a different tour that includes landing on the island.
