Ask ten different travelers to name the best islands to visit in Greece and you’ll get ten different answers, plus a small argument about ferry timetables. That’s part of the charm. With more than 200 inhabited islands scattered across the Aegean and Ionian seas, the country never hands you one obvious pick.
Stand on a caldera-edge terrace in Oia as the sun drops, and it becomes clear why Santorini keeps landing on every shortlist. But Greece holds a lot more than one famous view, and the right island really depends on what you want out of the trip, plus a few new rules for 2026 that change how some of these islands actually feel to visit.
This guide breaks things down by what actually matters on the ground: beaches, crowds, cost, and how far you’re willing to travel from the airport.

Why Santorini Still Tops Every List of the Best Islands to Visit in Greece
Santorini earns its reputation, even if locals will admit the crowds in Fira and Oia get rough by midday in July. The volcanic caldera, the black and red sand beaches at Perissa and Kamari, and the cave hotels carved into cliffside villages give it a look no other island quite matches.
Anyone who’s watched the sunset from Oia’s castle ruins knows why people book a room a year in advance. The trick locals share is simple: catch the same view from Imerovigli or Firostefani instead, where the crowds thin out and the angle is arguably better.
Best for: couples, honeymooners, first-time visitors who want the classic postcard version of Greece.
Skip it if: you’re traveling on a tight budget or you want to avoid tourist crowds in high season.
Mykonos and the Cyclades: Where the Party (and the Postcard) Started
Mykonos remains the loudest name in the Cyclades, known for whitewashed alleys, windmills, and a nightlife scene that runs from beach clubs straight through to sunrise. Paradise and Super Paradise beaches carry that reputation, for better or worse.
But the wider Cyclades group is where the real depth sits. Naxos, the largest island in the chain, has some of the best sand in the Aegean at Plaka Beach and a mountain interior full of villages that barely see tourists. Paros splits the difference between Santorini’s polish and Naxos’s calm, with the fishing village of Naoussa drawing a growing following of its own.
Milos deserves a mention on its own. Locals describe the coastline there as the most dramatic in the whole archipelago, with more than 70 beaches carved from volcanic rock, including the lunar-white cliffs of Sarakiniko.
Crete: The Island Big Enough to Feel Like Its Own Country
Crete is Greece’s largest island, and it plays by different rules. Four regions, Chania, Rethymno, Heraklion, and Lasithi, each carry their own character, from Chania’s Venetian harbor to the Minoan ruins at Knossos outside Heraklion.
Anyone who’s driven the south coast road toward Chora Sfakion knows the trade-off: rougher terrain, fewer crowds, and beaches like Elafonissi and Balos that feel worth the extra hour in the car. Families tend to gravitate here because there’s enough space to avoid the Santorini-style bottleneck, and flight connections from major European cities run all summer.
The Ionian Side: Corfu, Kefalonia and Zakynthos for Greener Scenery
The Ionian islands sit on the opposite side of the country, and they look almost nothing like the Cyclades. Corfu’s Old Town carries centuries of Venetian, French, and British influence in its architecture, giving it a different rhythm than the sun-bleached Aegean towns.
Kefalonia, the largest of the Ionian group, is famous for Myrtos Beach and a cave system worth a half-day trip on its own. Locals here will tell you the water off Myrtos looks almost unreal from the cliff road above it, and photos rarely do it justice.
Zakynthos, or Zante, holds the country’s most photographed beach: Navagio, the shipwreck cove only reachable by boat. It gets busy, but arriving before nine in the morning still buys a decent stretch of quiet water.
The Best Islands to Visit in Greece If You Want Fewer Crowds
Not every trip needs to chase the headline names. If crowds are the main worry, a handful of quieter islands consistently come up among travelers who’ve done the big three already.
- Folegandros — cliffside villages, almost no nightlife, and some of the calmest evenings in the Cyclades.
- Koufonisia — tiny, flat, and built entirely around beach days rather than sightseeing.
- Serifos — a working port town with a hilltop Chora that still feels lived-in rather than staged.
- Symi — pastel harbor houses in the Dodecanese, closer to Rhodes than most itineraries realize.
- Ithaca — Homer’s mythical homeland, with small family-run guesthouses standing in for big resorts.
Anyone who’s chased quiet corners of the Aegean knows these islands trade some convenience for a much slower pace, and most travelers who try one come back saying it was the best part of the trip.
The 2026 Overtourism Rules You Need to Know Before You Book
This is the part most guides still miss, and it changes how a Santorini trip actually feels this year. Starting in 2026, Santorini enforces a daily cap of 8,000 cruise passengers, and the way that cap gets calculated just got stricter. Ships are now counted at full berth capacity instead of the old 80 percent estimate, so a 3,000-berth ship takes up 3,000 slots instead of 2,400. In practice, that means noticeably fewer big ships docking on any given day.
There’s also a new tiered cruise levy: up to €20 per person in peak summer, dropping to €12 in spring and autumn, and just €4 in winter. Land-based travelers arriving by ferry or plane don’t pay this fee at all; it applies only to cruise disembarkations.
Here’s the twist most people don’t expect: Mykonos charges the same €20 peak levy but has no daily cap, and cruise arrivals there actually grew by 16 to 17 percent in 2025. The lesson is simple. A fee alone doesn’t reduce crowds; a hard cap does.
For travelers, the upside is real. With fewer cruise-day crowds, Santorini hotel rates have dropped noticeably compared to last year, with some properties running 14 to 22 percent cheaper and five-star rooms that cost over €700 a night in early summer now available closer to €500 in the shoulder months. Several beaches have also gained “Untrodden Beach” protection, banning sunbeds and permanent structures to keep the coastline closer to its natural state.
None of this should scare anyone off Santorini. If anything, 2025 and 2026 may turn out to be the calmest, best-value years the island has offered in a decade.
Getting Between Islands: Ferries, Flights and Realistic Timing
Island-hopping sounds romantic until you’re staring at a ferry schedule at 11 p.m. trying to work out connections. A few practical notes save real headaches.
High-speed ferries connect most of the Cyclades in under three hours, and booking through Ferryhopper or Ferries.gr a few weeks ahead avoids sold-out routes in July and August. Santorini, Mykonos, Naxos, and Paros all have domestic airports, which cuts travel time dramatically if the budget allows for it.
For the Ionian group, Corfu and Kefalonia both run direct flights from Athens and several European hubs, while Zakynthos connects easily by ferry from Kyllini on the mainland. Three islands per trip tends to be the sweet spot; anything more and you’ll spend half your holiday on boats.
Best Time of Year to Go
May, June, and the stretch from September into early October give the best balance of warm seas, long daylight, and manageable crowds. July and August bring peak heat and the busiest ports, along with the highest prices for rooms and ferry tickets.
Shoulder-season travelers who’ve made the switch rarely go back to August. Beaches stay open, restaurants stay less rushed, and prices on everything from tavernas to hotel rooms drop noticeably once the school-holiday crowds head home, and as the new cruise levy shows, shoulder season now saves money on the cap-and-fee front too.
Conclusion
There’s no single right answer to which Greek island deserves your time, and that’s really the point. The best islands to visit in Greece range from the caldera views of Santorini, now calmer and cheaper under the new 2026 cruise rules, to the quiet coves of Folegandros that never needed a cap to stay peaceful. Pick two or three, book ferries early, and let the island decide the rest.
