In 2026, Greece implemented daily visitor caps of 8,000 people on Santorini and introduced strict limits on mega-cruise ship arrivals in Mykonos. For travellers wanting to see these iconic islands authentically – without queuing for three hours to see a sunset – the answer is arriving by private sailing boat. A gulet cruise lets you anchor in the same bays as the superyachts, visit islands that commercial ferries never reach, and experience Greece the way it was 30 years ago.Official Greece Travel Guide

Why Greece Is Capping Visitors in 2026

For years, Greece’s tourism boom looked like an unqualified success story. Arrival numbers climbed every season, hotel occupancy hit record highs, and islands that were once sleepy fishing communities became global travel brands. But by the mid-2020s, the strain on infrastructure, water supplies, and local life had become impossible to ignore.

Santorini, in particular, became the poster child for overtourism. On peak summer days, more than 17,000 cruise passengers were disembarking onto an island with a permanent population of roughly 15,000 people. Streets in Oia and Fira turned into slow-moving human traffic jams by mid-morning, and the famous caldera-view sunset spots required arriving hours early just to find standing room.

In response, Greek authorities introduced a daily cap of 8,000 cruise visitors to Santorini in 2026, alongside new restrictions on the number of mega-ships permitted to dock in Mykonos on any given day. Local municipalities have also tightened rules around short-term rentals, beach club expansion, and vehicle access in historic centres. The goal isn’t to discourage tourism altogether – Greece’s economy depends heavily on it – but to protect the character of the islands and the quality of life for residents, while making the visitor experience more sustainable in the long run.

For independent travellers, this shift creates a new reality. Turning up in high season without a plan now means competing for a shrinking pool of walk-in availability, particularly on the islands everyone has heard of. The islands themselves haven’t become less beautiful – if anything, the caps are protecting what makes them special. But the way people access them needs to change.

The Problem With Visiting Santorini and Mykonos in 2026

Even with visitor caps in place, Santorini and Mykonos in peak season remain two of the busiest patches of coastline in the Mediterranean. The caps limit cruise arrivals, but they do very little to reduce the sheer volume of people already staying on the islands via hotels, ferries, and short-term rentals.

The practical problems for travellers haven’t disappeared – they’ve just shifted shape:

• Restricted spontaneity. With daily arrival limits, popular excursions, boat tours, and even restaurant tables need to be booked well in advance. Turning up and figuring it out as you go is far less realistic than it used to be.
• Concentrated crowds in a smaller footprint. Santorini is a small island. Even 8,000 capped daily arrivals, combined with existing hotel guests, still creates dense crowds around the caldera towns, the same handful of beaches, and the sunset viewpoints everyone photographs.
• Rising prices. Reduced supply against strong demand pushes prices upward – for accommodation, excursions, and even simple things like a table for dinner with a view.
• A homogenised experience. Much of what visitors see on Santorini and Mykonos today is built around tourism itself: souvenir shops, infinity pools, and photo-ready cafés, rather than the fishing villages and working ports these islands once were.

None of this means Santorini and Mykonos aren’t worth visiting – they absolutely are. But seeing them exclusively by staying on land, and trying to squeeze both into a single land-based itinerary, increasingly means spending a significant part of your holiday managing logistics rather than enjoying the islands.

How a Sailing Holiday Changes Everything

A gulet cruise solves the crowding problem in a way that no amount of clever land-based planning can. Instead of basing yourself in one town and taking day trips out, you bring your accommodation with you – a traditional wooden sailing boat that moves between islands, anchoring in bays and harbours that are simply inaccessible to the coach tours and cruise ship crowds.

The difference comes down to a few key advantages:

You control your own schedule. Rather than being tied to ferry timetables or excursion departure times, a private gulet moves at the pace your group sets. If a bay is busy, you sail on to the next one. If you find somewhere beautiful and quiet, you simply stay longer.

You reach places ferries don’t go. Commercial ferry routes connect major ports because that’s where the passenger volume is. Countless smaller islands, secluded coves, and quiet anchorages across the Aegean and Ionian have little or no ferry service at all – but they’re easily reached by sailing boat.

You see Santorini and Mykonos differently. Rather than arriving by ferry into the main port and joining the crowds on foot, a sailing itinerary can approach these islands by sea, anchor away from the main harbour, and visit at times of day when the day-trippers have gone home. You get the caldera views and whitewashed villages, minus the three-hour queue for a sunset photo.

Every day brings a new anchorage. Instead of one island for your whole trip, a week-long cruise typically visits five or more islands, so the crowding problem is spread out rather than concentrated. If one spot feels busier than expected, it’s simply part of a longer journey rather than the whole holiday.

It’s how Greece used to feel. Long before mass tourism, this coastline was explored by boat – fishermen, traders, and early travellers moved between islands by sea. A gulet cruise reconnects you with that older rhythm: swimming from the deck in clear water, eating fresh fish in tiny harbour tavernas, and waking up somewhere new.

5 Greek Islands You Can Only Reach by Boat

Beyond the household names, Greece has thousands of islands and islets, and many of the most beautiful are only practically accessible by private boat. Here are five worth seeking out on a sailing itinerary.

1. Polyaigos

Uninhabited and largely untouched, this small island near Milos has no ferry service and no permanent population – just dramatic cliffs, sea caves, and turquoise water that few travellers ever see.

2. Koufonisia’s hidden coves

While the main village of Koufonisia does get a ferry, the island’s best swimming spots – tiny coves with sculpted rock formations and impossibly clear water – are tucked along a coastline that’s far easier to reach by boat than on foot.

3. Marathi

A tiny islet in the Dodecanese with a handful of residents and a couple of family-run tavernas, Marathi is the kind of place where a gulet can anchor for lunch and you’ll barely see another visitor.

4. Paximada

Off the coast of Crete, this rocky islet has no infrastructure at all, but it’s a haven for wildlife and a striking, peaceful stop for swimming and snorkelling.

5. Sikinos

Often overlooked in favour of its neighbour Santorini, Sikinos has limited ferry connections, a slower pace of life, and Byzantine ruins with almost no other tourists in sight.

These are the kinds of stops that transform a Greek island holiday – not replacing the icons, but adding the contrast of true seclusion alongside them.

Our Crowd-Free Greece Sailing Routes

At Sail in Greece, our cruises are built around exactly this idea: combining the islands people come to Greece to see with the quieter anchorages that only a private gulet can reach.

Our Ionian Cruises explore the calmer, greener side of Greece – think Kefalonia, Ithaca, and Zante – where pine-covered hills meet turquoise bays, and the pace of island life feels noticeably slower than in the Aegean.

Our Zante Cruises focus on the beaches and sea caves of Zakynthos and its surrounding islets, including spots that are effectively unreachable except by boat, away from the beach-club crowds.

Our Rhodes Cruises combine the medieval old town of Rhodes with a chain of Dodecanese islands and hidden coves that most travellers never make it to.

For those wanting a livelier social atmosphere, our 18-39s Cruises and Mykonos Cruises blend the buzz of nightlife stops with plenty of swimming and quieter anchorages in between – so you get the party without spending your whole trip fighting crowds.

Our Harmony Cruises strike a balance between sightseeing, relaxation, and a touch of nightlife, ideal for groups with mixed priorities.

And for travellers who want full flexibility, our Yacht Experiences let you charter privately and shape the entire itinerary – including which crowded ports to skip entirely.

Every itinerary is built around a fleet of traditional wooden gulets, ranging from smaller Standard boats for intimate groups up to larger Luxury vessels for bigger parties, so the experience can be tailored to the group size and style of trip you’re after.

Practical Tips for Avoiding the Crowds in 2026

If you’re planning a Greek island trip this year, a few practical adjustments can make a significant difference to how crowded your experience feels.

Book well ahead, especially for July and August. With visitor caps in place on the busiest islands, availability for accommodation, excursions, and boat charters is tighter than in previous years. Early booking isn’t just about price – it’s about securing a spot at all.

Consider shoulder season. Late May, June, and September offer warm weather and calmer seas, with a fraction of the visitor numbers of peak summer. Many sailing routes are just as enjoyable, if not more so, outside the July-August peak.

Visit famous islands by sea, not by ferry. Arriving at Santorini or Mykonos by private boat, and anchoring away from the main port, avoids much of the disembarkation bottleneck that ferry and cruise passengers face.

Prioritise time on the water over time in town. The most memorable parts of a Greek island trip are often swimming in a quiet bay or watching the sunset from a boat deck – not standing in a crowd. Build your itinerary around these moments rather than ticking off towns.

Choose a smaller vessel and group size if you want more flexibility. Larger charter groups sometimes need to plan further ahead for anchorages and dinner reservations; smaller groups can be more spontaneous.

Pack light and pack smart. Space on a gulet is more limited than in a hotel room. A soft-sided bag, reef-safe sunscreen, and swimwear that dries quickly will serve you far better than a hard suitcase full of resort wear.

Talk to your operator about the current visitor caps. Rules can shift during the season, and an experienced local operator will know which anchorages and ports are quietest on any given week.

Frequently Asked Questions

Do the 2026 visitor caps mean I can’t visit Santorini or Mykonos this year? No. The caps limit the number of cruise ship passengers allowed to disembark each day; they don’t prevent independent travellers, including those arriving by private sailing boat, from visiting. Booking ahead and choosing quieter arrival times still gives you full access to both islands.

Is a gulet cruise suitable for people who aren’t experienced sailors? Yes. Gulets are crewed by an experienced captain and crew who handle all the navigation and sailing, so guests can simply relax, swim, and enjoy the itinerary without any sailing experience required.

How many islands do you typically visit on a one-week cruise? Most one-week itineraries call at five to seven islands and anchorages, combining well-known destinations with quieter bays and villages that aren’t accessible by regular ferry services.

When is the best time to book a Greece sailing holiday in 2026 to avoid crowds? Late May, June, and September tend to offer the best balance of good weather and lower visitor numbers, though July and August remain popular for those who don’t mind booking further in advance to secure availability.
