Famous path from Chora to the Church of Panagia (also known as the Church of the Assumption of the Virgin Mary) — Folegandros Church of Panagia

You’ve seen the Santorini sunsets. You’ve heard of the Mykonos beach clubs. But Greece is full of magical islands and secret spots that never make it to the average traveler’s itinerary—and that’s exactly why you need to know about them.

As a luxury Greece travel expert (who’s spent 20+ years curating unforgettable itineraries), I’m spilling my favorite hidden gems that most tourists miss entirely—but trust me, they’ll be the highlight of your trip.

1. Folegandros – Santorini’s Wild, Romantic Cousin

Imagine all the drama of Santorini’s cliffs—without the crowds, cruise ships, or Instagram mobs. Folegandros is raw, romantic, and wildly underrated.

Must-do: Watch sunset from the Church of Panagia. It’s a hike—but it’ll take your breath away.

2. Koufonisia – Where You Barefoot Hop from Beach to Beach

This tiny Cycladic duo (Pano and Kato Koufonisi) is laid-back luxe at its finest. Crystal clear water, secret sea caves, and the kind of local tavernas that don’t need menus.

Insider tip: Charter a boat to Kato Koufonisi for the ultimate secluded swim.

3. Paxos & Antipaxos – Corfu’s Hidden Neighbors

Just south of Corfu lie two of the most charming Ionian islands. Think Italian villa energy meets Greek fishing village charm, with sapphire coves perfect for yacht-hopping.

Don’t miss: A wine-fueled lunch at Voutoumi Beach on Antipaxos. It feels like your own private paradise.

4. Kimolos – Milos’ Quiet Sister

If you love Milos for its moon-like beaches, you’ll swoon for tiny Kimolos. Just a 30-minute hop away, it offers untouched beaches, artisanal bakeries, and the kind of quiet that resets your soul.

Vibe: Greece, 40 years ago.

5. Syros – The Cycladic Capital with Neoclassical Glam

Syros doesn’t feel like a secret, but it flies totally under the radar. This is where Greeks vacation—and where marble squares, opera houses, and pastel mansions meet sun-drenched beaches.

Must-see: Aegean sunset from the aristocratic Vaporia district.

Final Thoughts: Add These to Your Greece Bucket List

The beauty of Greece isn’t just in the places you’ve heard of—it’s in the places that surprise you. That feel untouched. That give you space to breathe, explore, and fall in love with Greece in your own way.
