Mykonos draws over 2.2 million visitors annually, yet a 20-minute sail away lies an island with no hotels, no roads, no ferries. Rhenia is the uninhabited counterpart to sacred Delos, and for families seeking a day of genuine quiet, it offers something the beach clubs cannot: uninterrupted time together. For a broader look at what the island offers beyond the water, the Mykonos destination guide covers accommodation, dining, and seasonal considerations.
Yes, but only if you skip the group tours and charter a private vessel. Rhenia’s four coves offer the kind of empty shoreline that lets children splash without supervision and parents reset. The catch is cost — private charters start around €650, and you need to plan around the Meltemi winds that can make the crossing uncomfortable for younger kids.
Why Rhenia Works for Families
Rhenia sits immediately west of Delos, four times its size, yet carries none of its crowds. Because births and deaths were forbidden on sacred Delos grounds, Rhenia served as its necropolis — a history that left the island without permanent settlement. Today, no beach bars, umbrellas, or music disturb the shoreline. For a family, this means the only sounds are the boat engine and the water.
The four main coves — Glyfada, Stena, Lia, and Ambelia — each offer a different shade of blue and a different level of shelter. Glyfada is often called the “Blue Lagoon” of the Cyclades, its shallow sandy bottom reflecting sun to create a neon glow. Stena is a narrow channel that feels like entering a private sanctuary. Lia and Ambelia sit further from the main approach, preferred lunch spots for private charters because they stay sheltered from wind even when the Meltemi picks up elsewhere.

If you want to explore these coves at your own pace, there are options for sailing trips from Mykonos that can be tailored to family schedules. For those who prefer a faster crossing to maximize swim time, catamaran cruises offer more stability in choppy conditions — a real advantage when traveling with young children.
The Four Coves at a Glance
Before you decide which bay to make your base, it helps to understand what each offers. The table below compares them directly.
| Cove | Best for | Water conditions | Seclusion | Standout detail |
|---|---|---|---|---|
| Glyfada | First swim stop | Shallow, sandy bottom | Moderate — other boats may visit | Water glows neon blue in afternoon sun |
| Stena | Families with young children | Calm, narrow channel | High — feels like private entrance | Protected from Meltemi; minimal current |
| Lia | Lunch anchor | Sheltered, steady | High — fewer boats stop here | Preferred by charter crews for wind protection |
| Ambelia | Total privacy | Deep water close to shore | Very high — often alone in peak season | Rocky outcrops with sea anemones and silver fish |
Note that none of these coves have infrastructure. There are no bathrooms, no shade structures, no places to buy water. Everything you need for the day — food, drinks, sunscreen, towels — must come on the boat with you. The trade-off is that the water visibility is superior to almost anywhere else in the Cyclades because there is no permanent human presence to stir up sediment.
Choosing Your Vessel for a Family Day
The crossing from Mykonos to Rhenia is short — roughly 20 to 40 minutes — but the Aegean can be unpredictable. Vessel choice determines the rhythm of your entire day.
High-performance RIBs (rigid inflatable boats) can make the trip in under 20 minutes, giving you first access to the best coves before larger tour boats arrive. The day cruises available from Mykonos range from these fast options to more comfortable motor yachts. For families, a motor yacht with stabilizers provides a smoother ride and more deck space for lounging. Sailing vessels offer a slower, more romantic pace but can feel rocky when the Meltemi blows.
Aim for a 10:00 AM departure from Mykonos. This puts you ahead of the midday heat and ahead of the large tour boats that leave harbor around 11:00. By 10:30 you can be anchored in Glyfada with the cove to yourself.
For families considering snorkeling, snorkeling excursions from Mykonos often include gear and guidance, though on a private charter you can bring your own and stay as long as you like.
The Meltemi winds typically intensify from late morning through afternoon, especially July and August. The return leg from Rhenia to Mykonos can become choppy. If anyone in your family is prone to seasickness, take motion-sickness medication before boarding, not after the boat starts rocking.
Practical Timing and What to Know
The best months for a family trip to Rhenia are May, June, and September. In May and June, the sea is calm, the water warm enough for swimming, and the crowds at Delos — which you can combine with your Rhenia day — are thinner. July and August bring the Meltemi and the highest number of cruise passengers; Mykonos received approximately 900 cruise ships in 2025, according to port projections. Morning departures are essential in those months.
Delos and Rhenia are often combined in a single day because they sit only 15 minutes apart by boat. A typical schedule: depart Mykonos at 09:00, spend 1.5 hours at Delos before it gets hot, then cross to Rhenia for swimming and lunch. This gives you the archaeological context of Delos — the Terrace of Lions, the House of Dionysus — followed by the unfiltered nature of Rhenia. It’s a full day, roughly 6 to 6.5 hours, but the contrast between the two islands is what makes the trip memorable.
If you want to skip Delos entirely and spend the whole day at Rhenia, that’s the advantage of a private charter — you dictate the itinerary. Some families prefer to anchor at Lia by 11:00, swim until lunch, then move to Ambelia for the afternoon while the kids nap on deck.
Is Rhenia suitable for young children?
Yes, with caveats. The water entry is often via boat ladder, which some small children find intimidating. Bring a life vest or ask the crew for swimming noodles. The coves have no facilities, so pack diapers, snacks, and plenty of water.
The calm conditions at Stena make it the best choice for families with toddlers — the protected channel has minimal current and shallow entry points near the shore.
What’s the best time of year to visit Rhenia?
Late May through June offers the best balance: warm water, calm seas, and Delos crowds that are still manageable. September is similar but with the added benefit of cooler air temperatures for hiking on Delos.
July and August are hot, windy, and expensive. If you visit then, book your charter 3 to 6 months in advance — the best vessels and captains go first.
How much does a private charter to Rhenia cost?
Private RIB boats for up to 6 people range from €650 to €900 total, including lunch, drinks, and snorkeling gear. Full-sized luxury motor yachts cost more — expect €150 to €250+ per person for a premium experience.
Shared group tours run €70 to €120 per person, but you lose the flexibility to choose your coves and your schedule. For a family seeking solitude, the private option is the only one that delivers.
Can you visit both Delos and Rhenia in one day?
Yes, and most people do. The proximity — about 15 minutes between the two islands — makes it efficient. A guided tour of Delos takes about 1.5 hours, then you cross to Rhenia for 2 to 3 hours of swimming and lunch.
The risk is that the combined day feels rushed if you want deep time at either site. Families who prioritize swimming over archaeology might prefer to skip Delos and stay anchored at Rhenia all day.
What should we bring for a day trip to Rhenia?
Swimwear, towel, sunscreen, hat, and a windbreaker are essential. The boat ride can be wet, and Delos has almost no shade. Bring your passport or ID for Delos entry — copies are usually accepted.
Water shoes help with the rocky shoreline at Rhenia’s coves. If you use prescription snorkeling masks, bring your own — provided gear is basic. Motion-sickness medication is recommended even if you don’t usually get seasick; the Meltemi can surprise you.
Rhenia remains the kind of place that resists description because what makes it valuable is what isn’t there: no announcements, no schedules, no commerce. For a family, a day anchored in Ambelia with the water lapping against the hull and no other boats in sight is a reminder that solitude isn’t something you buy — it’s something you navigate toward.
