9 Greek Islands You’ve Never Heard of (But Need to Visit)

There’s something about Greek islands that feels timeless—the way the whitewashed houses reflect the sun, the scent of olive groves in the air, and the endless stretch of blue where the sky meets the sea.

With thousands of islands scattered across the Aegean and Ionian Seas, there’s no shortage of beauty. But let’s be honest: some, like Santorini and Mykonos, can feel more like tourist traps than relaxing escapes.

The good news? Greece has plenty of islands where you can enjoy stunning landscapes, quiet beaches, and authentic experiences without the crowds. Here’s what you need to know to plan your trip and explore some of the country’s hidden treasures.

A Quick Look at Greece’s Islands

Greece is home to over 6,000 islands and islets, but only 227 are inhabited. These islands are grouped into distinct clusters, each offering something unique. The Cyclades are known for their whitewashed buildings and turquoise waters, while the Ionian Islands bring lush greenery and Venetian charm. In the North Aegean, you’ll find islands rich in history, and the Sporades offer dense forests alongside idyllic beaches. From Crete’s rugged mountains to the medieval towns of the Dodecanese, there’s a corner of Greece for every traveler.

Islands That Feel Too Crowded

Some islands have earned global fame, but their popularity can be overwhelming. Take Santorini, for example. Its sunsets are legendary, but with over a million cruise passengers visiting each year, the streets can feel more packed than picturesque. Mykonos, another hotspot, is famous for its nightlife but often struggles with overcrowded beaches and inflated prices.

According to recent data, Santorini and Mykonos see an annual influx of over 1.3 million and 1.2 million cruise passengers, respectively. These numbers don’t account for the additional tourists arriving by air or ferry, making it clear why these islands feel so busy.

If you’re set on visiting these iconic spots, consider coming in May or October. The weather is still lovely, and the crowds thin out, letting you enjoy the charm without the chaos.

Where to Escape the Crowds

Luckily, Greece’s lesser-known islands offer just as much beauty and a lot more breathing room. Here are some worth exploring:

Anafi

Anafi sits quietly near Santorini, but it couldn’t feel more different. Life here moves slowly, with empty beaches, simple tavernas, and trails that take you to stunning views. While Santorini’s streets are brimming with over a million visitors, Anafi sees only a fraction of that traffic, offering a peaceful alternative for those looking to truly relax.

Getting there: Ferries from Piraeus or Santorini. Check schedules carefully, as services can be limited.

Kythira

Positioned between the Peloponnese and Crete, Kythira offers an enchanting mix of waterfalls, Venetian castles, and secluded coves. Unlike its busier counterparts in the Cyclades, Kythira remains largely off the radar for mass tourism, preserving its authentic charm and slow pace.

Getting there: Fly from Athens or take a ferry from Neapolis.

Lemnos

Lemnos is all about untouched beauty. With its wide, sandy beaches and volcanic landscapes, it’s an island for those who love nature. Compared to the crowded Cycladic islands, Lemnos attracts far fewer visitors, giving you plenty of room to enjoy its serenity.

Getting there: Direct flights from Athens or ferries from Lavrio port.

Symi

Symi’s pastel-colored harbor might be one of the most picturesque in Greece. Spend your time swimming in clear waters, hiking to quiet monasteries, or just wandering the charming streets. While Symi sees day-trippers from Rhodes, its evenings are peaceful, offering a much-needed respite.

Getting there: Ferries from Rhodes make Symi an easy addition to your itinerary.

Ithaca

Known as the home of Odysseus, Ithaca is a peaceful escape. Explore its quiet villages, hike trails with sweeping sea views, or find your own secluded bay for a swim. Its charm lies in its slow pace and modest number of visitors, especially compared to nearby Kefalonia.

Getting there: Ferries from Kefalonia or mainland Greece.

Tilos

Tilos, part of the Dodecanese, is a haven for nature lovers. This small island is known for its hiking trails, unspoiled beaches, and quiet charm. Unlike the bustling hotspots, Tilos has intentionally limited visitor numbers, creating an eco-conscious and serene destination.

Getting there: Ferries from Rhodes or Kos.

Paxos

Just south of Corfu, Paxos is an Ionian gem with crystal-clear waters and olive groves that seem to stretch forever. The island’s laid-back vibe makes it perfect for unwinding. With fewer visitors than the larger Ionian islands, Paxos feels like a private retreat.

Getting there: Ferries from Corfu.

Folegandros

Folegandros combines Cycladic charm with a fraction of the crowds of its neighbors. Wander through the stunning cliffside town of Chora, where every corner offers a photo-worthy view. Its beaches, like Agali, feel like private escapes compared to the busier islands in the group.

Getting there: Ferries from Piraeus or Santorini.

Amorgos

Amorgos is where you go to feel like you’ve stepped into another time. Known for its dramatic cliffs and the iconic Monastery of Hozoviotissa, this island is perfect for hiking and soaking up the raw beauty of the Aegean. Despite growing popularity, it remains quieter than its Cycladic neighbors.

Getting there: Ferries from Piraeus or nearby Cycladic islands.

Tips for Island Travel

Traveling around Greece’s islands can be an adventure in itself. Ferries are the main way to get around, but schedules can vary depending on the season, so planning ahead is key. For some of the quieter islands, flights from Athens are a faster and easier option. Once you arrive, renting a car or scooter can make exploring more flexible, especially if public transport is limited.

The best time to visit is in late spring or early autumn when the weather is warm, and the crowds are lighter. And when it comes to where to stay, small guesthouses or family-run accommodations often provide the warmest welcome.

Why These Islands Deserve Your Time

Greece’s magic isn’t confined to its famous spots. The quieter islands offer something just as special: the chance to slow down, connect with nature, and experience Greek culture without distractions. Whether it’s watching the sunset over Anafi’s cliffs or wandering the colorful harbor of Symi, these islands prove that you don’t need to follow the crowds to find beauty.

But you don’t have to skip the big hitters entirely. Consider adding some of these lesser-known gems as side trips to balance your journey. You might find that the contrast makes both experiences even more memorable. So, why not take the road less traveled and discover a different side of Greece? It might just be the highlight of your trip.
