The Best Less-Crowded Greek Islands for Summer Escape

Beat the Crowds: Greece's Quietest Summer Island Escapes

Let’s face it—Greece in the summer is a magnet for tourists from around the globe. With its whitewashed villages, sun-kissed beaches, and ancient ruins, it’s no surprise that July and August are absolute peak months. But what if you're craving that quintessential Greek island experience without the chaos of cruise ships and packed tavernas?

The good news? While hotspots like Santorini and Mykonos are swarmed with selfie sticks and sun-seekers, there are still serene corners of Greece where you can bask in island magic—minus the mobs. Here’s your insider’s guide to Greece’s underrated and less-crowded islands worth escaping to in high season.

1. Kefalonia & Ithaka – Myth Meets Solitude

Kefalonia, the largest of the Ionian Islands, offers a mix of wild beauty, dramatic coastlines, and Greek authenticity. Despite its international airport, much of the island—especially areas like Agia Efimia and Assos—remains peaceful even in August. You’ll find pristine beaches (like secluded Foki and Petani), lush forests, and charming fishing villages untouched by mass tourism.

Just a short hop away lies Ithaka, the legendary home of Odysseus. With no airport and limited ferry access, Ithaka naturally filters out the crowds. Expect winding mountain roads, hidden coves like Gidaki, and a slow rhythm of life that feels like a throwback to old-world Greece.

2. Tinos – A Cycladic Secret

Often overshadowed by neighboring Mykonos, Tinos is the Cyclades’ best-kept secret. It boasts stunning beaches, quaint villages like Pyrgos, and a deep spiritual heritage. No airport, no cruise ships—just an authentic vibe and room to breathe. Despite its proximity to more popular islands, Tinos manages to stay under the radar, making it a haven for travelers in the know.

3. Milos – Breathtaking Yet Manageable

Yes, Milos has gained traction in recent years, but it still operates on a small scale. With a limited number of hotels and a tiny airport, the island can’t physically host large crowds. To avoid the day-time rush at popular spots like Sarakiniko or Kleftiko, head out early or late. Explore off-the-radar beaches like Kastanas or take a local fisherman’s boat to nearby Poliegos—an uninhabited island where turquoise waters and empty sands await.

Pro Tip: Skip staying in Pollonia or Adamas’ busiest areas. Find a quiet guesthouse inland or near the southern beaches to enjoy Milos at its most peaceful.

4. Lesvos – The Undiscovered Giant

If you're looking for an island that blends culture, gastronomy, and nature with minimal crowds, Lesvos (also called Lesbos) is your jackpot. It's large—big enough to offer variety without being swamped by tourists. While beach towns like Molyvos see some action, the island overall remains chilled out, even in August.

Highlights include:

• The Petrified Forest, one of the largest in the world
• Ouzo distilleries and wineries
• Hidden beaches like Vatera
• Vibrant festivals, local cheeses, and rustic mountain villages

Lesvos is also ideal for road-trippers. With a rental car, you’ll easily escape the handful of busy spots and explore its incredible diversity.

5. Tilos, Kalymnos & Nisyros – Quiet Dodecanese Charms

Thinking of exploring the Dodecanese? Skip Rhodes, which is bustling in high season, and consider lesser-known gems like:

• Tilos – Greece’s first energy self-sufficient island. It’s quiet, sustainable, and full of hiking trails, pebbled beaches, and a deep sense of calm.
• Kalymnos – A rock climber’s paradise with local charm and far fewer tourists than neighboring Kos.
• Nisyros – Home to an active volcano and quaint whitewashed villages. Its lunar landscapes and tranquil vibe make it one of Greece’s most fascinating escapes.

All three are accessible by ferry and remain off the mainstream tourist radar—even in July and August.

6. Sifnos & Folegandros – The Cycladic Sweet Spot

No airport? No problem. That’s exactly what keeps Sifnos and Folegandros refreshingly quiet.

• Sifnos is all about relaxed sophistication—great food (seriously, it’s a culinary hotspot), hiking trails, and intimate beaches like Vathi or Faros.
• Folegandros offers dramatic cliffs, crystal-clear waters, and one of the most photogenic choras (villages) in the Cyclades. While it’s getting noticed, its size and ferry-only access help keep things calm.

Both are ideal for travelers looking for authenticity without sacrificing comfort.

7. Limnos & Kythira – Remote and Remarkable

Last but not least, consider Limnos and Kythira—two wildly underrated Greek islands.

• Limnos, in the North Aegean, is windswept and wild with long beaches, ancient ruins, and local wines. It’s got a chilled vibe and is rarely crowded.
• Kythira, off the Peloponnese coast, is a romantic blend of Ionian, Cycladic, and Cretan influences. Think waterfalls, Venetian castles, and empty beaches even in August.

Both are perfect if you’re up for a bit of extra travel and a lot of extra tranquility.

Final Island Hack: Skip the Airports

Islands without airports are your best bet for escaping the summer swarm. They tend to have fewer visitors simply because they're harder to reach—and that’s exactly what makes them special.

So whether you’re a mythology buff headed for Ithaka, a nature lover drawn to Lesvos, or a minimalist beachgoer eyeing Tilos, Greece still has plenty of places where serenity and summer can coexist.
