This guide goes beyond the postcard pictures to provide a deep dive into what makes each destination special, along with practical tips to plan your journey through this magnificent corner of the Mediterranean.
1. Santorini: The Iconic Romantic Escape
When people envision the best islands Greece has created, Santorini (Thira) is often the first that comes to mind. Born from a catastrophic volcanic eruption, its dramatic caldera views, black and red sand beaches, and dazzling white architecture are utterly unparalleled.
Best For: Honeymooners, couples, and photographers seeking the quintessential Greek island experience.
Highlights & Experiences:
- Oia’s Sunset: The daily pilgrimage to the village of Oia for sunset is a rite of passage. The sight of the sun dipping below the horizon, painting the sky in hues of orange, pink, and purple, is a genuinely magical spectacle. For a more intimate experience, book a table at a cliffside restaurant or watch from the ruins of the Byzantine Castle.
- Luxurious Caldera Stay: The iconic cave-house hotels carved into the cliffside are a destination in themselves. Waking up to an infinite blue view from your private plunge pool is the epitome of luxury.
- Volcanic Wine Tours: Santorini’s unique volcanic soil produces Assyrtiko grapes, resulting in some of Greece’s most distinctive and celebrated wines. A tour of local vineyards like Santo Wines or Venetsanos offers stunning views and insightful tastings.
- Ancient Akrotiri: Step back in time at this incredibly well-preserved Minoan Bronze Age settlement, often called the “Minoan Pompeii.” It offers a fascinating glimpse into a sophisticated civilization frozen in time by the volcanic eruption.
- Unique Beaches: Swim at the otherworldly Red Beach, with its towering crimson cliffs, or the Perissa and Kamari beaches, known for their striking black volcanic sand.
Practical Tips: Santorini is incredibly popular. To avoid the worst of the crowds, visit in the shoulder seasons (April-May or September-October). If you’re there in peak season, explore Oia early in the morning before the cruise ship passengers arrive.
2. Mykonos: The Glamorous Playground
If Santorini is about romance, Mykonos is about revelry. Synonymous with glamour, world-class DJs, chic boutique shopping, and vibrant nightlife, it’s a magnet for the international jet set and those looking to see and be seen.
Best For: Party enthusiasts, luxury shoppers, and social travelers craving energy and style.
Highlights & Experiences:
- Legendary Beach Clubs: Spend your day at beach clubs like Scorpios, Nammos, or Paradise Beach, where the party starts at noon and transitions seamlessly from sunbathing to dancing under the stars.
- Mykonos Town (Chora): Lose yourself in a maze of immaculate whitewashed streets adorned with colourful bougainvillea. Discover high-end boutiques, art galleries, and the iconic 16th-century windmills overlooking the sea.
- Little Venice: This picturesque neighbourhood, with its medieval houses built right on the water’s edge, is the perfect spot for a romantic cocktail at dusk.
- Historical Day Trip to Delos: Just a short boat ride away lies the sacred island of Delos, one of the most important mythological, historical, and archaeological sites in Greece. As the mythical birthplace of Apollo and Artemis, its extensive ruins are a UNESCO World Heritage Site and a must-visit for history lovers.
Practical Tips: Mykonos is one of the most expensive Greek islands. Book accommodations and popular beach club sunbeds well in advance. The wind (known as the meltemi) can be strong in July and August, so pack a light jacket.
3. Milos: The Adventurer’s Lunar Paradise
For those seeking a more raw and authentic experience, Milos is rapidly becoming known as one of the true best islands Greece keeps somewhat secret. This volcanic island boasts a coastline of extraordinary geological formations, over 70 unique beaches, and a laid-back, unpretentious atmosphere.
Best For: Nature lovers, photographers, couples, and travelers looking to escape the crowds.
Highlights & Experiences:
- Sarakiniko Beach: Often described as a lunar landscape, Sarakiniko is arguably Greece’s most photographed beach after Navagio. Its smooth, wind-sculpted white volcanic rock formations contrast starkly with the deep blue of the Aegean Sea, creating an utterly surreal and beautiful environment for swimming and exploration.
- The Fishing Villages: The colourful, boat-filled syrmata (fishermen’s garages) in villages like Klima, Mandrakia, and Firopotamos are postcard-perfect. In Klima, you can even stay in one of these converted traditional homes.
- Kleftiko: This famous complex of sea caves was once a hideout for pirates. Today, it’s best explored by boat tour, offering incredible opportunities for swimming and snorkeling in crystal-clear turquoise waters.
- Rich History: Milos is where the famous statue of Venus de Milo was discovered, now housed in the Louvre. You can visit the site in the ancient city of Klima and see a replica at the island’s archaeological museum.
Practical Tips: The best way to explore Milos is by renting an ATV or a car, as public transport doesn’t serve all the remote beaches. Boat tours are essential to access secluded spots like Kleftiko.
4. Crete: The Colossus of Culture and Nature
Crete isn’t just an island; it’s a universe of its own. As Greece’s largest island, it stands out among the best islands Greece offers due to its sheer diversity. Here, you’ll find everything from palm-tree-lined beaches and rugged mountains to vibrant cities and some of the country’s most important archaeological sites.
Best For: Families, history enthusiasts, foodies, hikers, and anyone who wants a truly varied vacation.
Highlights & Experiences:
- Minoan Palace of Knossos: Explore the sprawling ruins of Europe’s oldest city and the centre of the powerful Minoan civilization. The complex palace, with its legendary connection to the myth of the Minotaur, is a captivating historical journey.
- Samaria Gorge: A hiker’s paradise. This 16km trek through one of Europe’s longest gorges, located in the White Mountains National Park, offers stunning scenery and ends at the Libyan Sea.
- Charming Old Towns: The Venetian harbours of Chania and Rethymno are incredibly romantic, with their lighthouse, Ottoman architecture, and narrow shopping streets filled with tavernas and cafes.
- Culinary Journey: Cretan cuisine is renowned as one of the healthiest and most delicious in the world. Indulge in fresh cheese (graviera), dakos (rusk salad), superb olive oil, and mountain herbs. Don’t miss a food tour or a visit to a local farm.
Practical Tips: You cannot see Crete properly in less than a week. Renting a car is essential to explore its diverse landscapes, from the beaches of Elafonissi and Balos in the west to the Lasithi plateau in the east.
5. Naxos and Paros: The Authentic Cycladic Duo
For a perfect blend of beautiful beaches, traditional village life, excellent food, and just enough nightlife, the neighbouring islands of Naxos and Paros are top contenders for the best islands Greece has for a balanced and authentic vacation. They are often visited together due to their proximity and frequent ferry connections.
Best For: Families, solo travelers, windsurfers, and those seeking a genuine Cycladic experience without the extreme crowds or prices of Mykonos or Santorini.
Highlights & Experiences:
- Naxos: The largest Cycladic island is the greenest and most fertile. It’s famous for its magnificent beaches (like Plaka and Agios Prokopios), the impressive Portara (a massive marble gateway from 530 BC), and stunning mountain villages like Apeiranthos and Halki, where you can sample local kitron liqueur.
- Paros: Often considered the more lively of the two, Paros boasts the charming fishing village of Naoussa with its chic bars and excellent seafood tavernas, the picturesque Parikia town, and golden sandy beaches like Golden Beach and Kolymbithres. It’s also a world-class windsurfing destination.
- Day Trip to Antiparos: A short ferry ride from Paros, this tiny, quiet island is perfect for a day of pristine swimming and visiting its famous cave.
Practical Tips: September is an ideal time to visit, as the sea is warm from the summer sun and the crowds have thinned. Use the efficient ferry system to island-hop between them easily.
6. Beyond the Classics: Greece’s Hidden Gem Islands
While the names above are famous for a reason, part of discovering the best islands Greece has to offer is venturing off the well-trodden path.
- Tinos: A place of pilgrimage with a famous church, but also an island of stunning villages (like Pyrgos), dovecores, and a strong artistic tradition, often overlooked by its neighbours Mykonos and Andros.

7. Practical Planning for Your Greek Island Adventure
When to Go:
- Shoulder Season (May-June & September-October): The absolute best time. The weather is perfect for exploring and swimming, prices are lower, and the crowds are manageable.
- Peak Season (July-August): Expect intense heat, crowded streets and beaches, and the highest prices. Book everything far in advance.
- Off-Season (November-April): Many hotels and restaurants close, but it’s a unique time for solitude and experiencing local life, though swimming is off the table.
