Greece has more than 200 inhabited islands, but most travelers end up visiting the same handful every summer. Santorini, Mykonos, and Crete are beautiful, but they also attract enormous crowds, cruise ships, and rising prices.

What many people don’t realize is that some of the most memorable Greek island experiences happen on much smaller islands where daily life still moves at a slower pace.

Across the Aegean and Ionian Seas, there are islands where fishermen still gather in small harbors in the morning, family-run tavernas serve seafood caught the same day, and evenings revolve around a walk through the village square rather than beach clubs.

In this guide you’ll discover five underrated Greek islands that remain surprisingly peaceful: Kythira, Kastellorizo, Alonissos, Tilos, and Folegandros. Each one offers something slightly different, from quiet hiking trails and nature reserves to colorful harbor towns and small cafés overlooking the sea.

If you love Greece but prefer places that feel more local and less crowded, these islands are worth adding to your list.

Where These Lesser-Known Greek Islands Are Located

The islands in this guide are spread across several different parts of Greece. Folegandros sits in the Cyclades in the southern Aegean, while Alonissos belongs to the Sporades islands further north. Tilos and Kastellorizo are part of the Dodecanese island group near the Turkish coast, and Kythira lies just south of the Peloponnese.

Because they’re located in different regions, getting to them usually involves a ferry from Athens or a short domestic flight followed by a ferry connection. For example, Alonissos is commonly reached via Skiathos, while Tilos and Kastellorizo are often accessed from Rhodes.

Knowing which island group they belong to can make planning much easier when you’re mapping out a trip through Greece.

Best time to visit these quieter Greek islands

The best months to visit most of these islands are May, June, and September. The weather is warm enough for swimming, ferries run frequently, and the islands feel far more relaxed than during the peak August holiday period.

July and August are still beautiful, but they are also the busiest months across Greece.

Even late September and early October can be wonderful for islands like Kythira and Folegandros, when the sea stays warm and the villages return to a slower pace.

Quick list: underrated Greek islands in this guide

Kythira – quiet beaches and Venetian villages south of the Peloponnese
Kastellorizo – colorful harbor island near the Turkish coast
Alonissos – nature-focused island in the Sporades marine park
Tilos – tiny Dodecanese island known for hiking and wildlife
Folegandros – Cycladic island with dramatic cliffs and a beautiful Chora

Kythira: The Hidden Jewel Between Peloponnese and Crete

Kythira sits south of the Peloponnese, right where the Aegean and Ionian seas meet. It’s technically part of the Attica region, but geographically it feels much closer to the Peloponnese than to the Cyclades islands most people know.

The island is known for its dramatic cliffs, waterfalls hidden in green valleys, and villages that seem suspended in time. Kythira has a quieter, slightly wild atmosphere that attracts travelers looking for a Greek island that still feels largely undiscovered.

Getting here takes a little more effort than flying straight to Santorini or Mykonos, which is one of the reasons the island still feels relaxed. From Athens you can either fly to Kythira Airport in about 50 minutes or take a ferry from Piraeus, which takes around six hours. Some travelers also drive through the Peloponnese and take a shorter ferry from the small port of Neapoli.

Whether you’re wandering the narrow, cobblestone streets of Chora (the island's capital), soaking up the sunshine on the peaceful beach of Firi Ammos, or discovering the ancient ruins of Paleochora, Kythira offers a quiet, intimate experience of Greece.

A must-see? The dramatic waterfalls at Mylopotamos, which cascade through lush greenery, offering the perfect backdrop for reflection or a peaceful picnic.

If you're looking for a cozy place to stay on Kythira, Nostos Guesthouse in Chora is a total gem. It’s small (only seven rooms) so it has this really intimate, homey vibe that makes it feel like you’re staying with friends. The décor is full of cool antiques, giving the place a cozy, welcoming feel. The hosts are super friendly and make sure you feel right at home. It’s also in the heart of Chora, so you’re just a short stroll from charming cafés, quirky little shops, and the Venetian castle. If you're after a peaceful, authentic spot to unwind and enjoy the local charm, this is definitely the place.

And don’t miss Ammos Restaurant, a small family-run tavern where you can savor local seafood like grilled octopus and fresh sardines. Mark this place! If you’re looking for the best coffee on the island, Veranda Café is a must. With its laid-back vibe and stunning views of the town and sea, it’s the perfect place to sip on a coffee and just soak it all in. Whether you’re in the mood for a rich Greek coffee or something more refreshing, the drinks here hit the spot. And if you're feeling peckish, their sweet and savory waffles are a treat.

If you enjoy this quieter side of Greece, the rugged Mani Peninsula on the southern Peloponnese has a similar atmosphere, with stone villages, dramatic coastlines, and a slower pace of travel.

Kastellorizo: Greece’s Tiny, Colourful Paradise

Nestled just off the Turkish coast, Kastellorizo (also known as Megisti) is the smallest of the Dodecanese islands, but don’t let its size fool you - it’s packed with charm.

Kastellorizo is one of the easternmost islands in Greece, sitting just a few kilometres from the Turkish coast. It’s part of the Dodecanese islands, far away from the busy Cyclades routes that most summer travelers follow.

Most people reach the island via Rhodes. You can fly from Athens to Rhodes in about an hour and then continue by ferry to Kastellorizo, which takes roughly two to three hours. There are also small regional flights between Rhodes and Kastellorizo. Because it takes that extra step to get here, the island remains surprisingly quiet even in summer.

This island feels like a true gem, where time slows down and life revolves around the azure sea, fresh fish, and the vibrant pastel-colored buildings that line the waterfront. It’s the kind of place where you’ll want to take a deep breath and just be…

Once you step foot on this tiny island, you’ll immediately feel the peace and quiet surrounding you. Wander along the harbor, where fishing boats gently bob on the crystal-clear waters, and the air is filled with the scent of the sea. A must-visit spot is the Blue Cave: a stunning natural wonder where sunlight streams in, creating a glowing, almost otherworldly blue light inside the cave. If history piques your interest, take a trip up to the Castle of the Knights. Perched high above the town, the views of the Aegean from here are absolutely breathtaking, and it’s a perfect spot to snap some photos.

A good place to sit in the evening is Alexandros Restaurant, right along the harbor, where tables face the colorful houses across the water.

For a truly special stay on Kastellorizo, Casa Mediterraneo is the place to be. This charming boutique hotel is tucked into three beautifully restored neoclassical mansions, each with spacious suites offering amazing views of the harbor and the Sea of Crete. The interiors mix Mediterranean, Ottoman, and French styles, with sun-kissed plaster walls, soft textiles, and marble touches that create a relaxed, stylish vibe.

What makes this spot even better is its location - just a short stroll from the harbor, so you can easily explore the island while still enjoying the peace and quiet. In the mornings, enjoy a fresh breakfast under a shaded pergola, and in the evening, the terrace is perfect for sipping a cocktail while watching the sunset. For something a little extra, they offer yoga sessions, and there's a boutique with unique finds from the owners' travels. If you’re after a peaceful and beautifully designed place to stay on Kastellorizo, Casa Mediterraneo offers the perfect mix of relaxation and style.

And when it comes to food, Pantelis Restaurant is a must-try. They serve incredible seafood, and the view is nothing short of spectacular. Be sure to sip on some ouzo while watching the sunset - it’s the perfect way to end your day and really soak in the beauty of this quiet, charming island. It can be busy at times, but it’s such a cozy place so it’s just nice with people around!

Alonissos: The Quiet Heart of the Northern Sporades

For a truly serene escape, Alonissos should totally be on your radar. It’s part of the Northern Sporades group of islands, but it still feels like one of the hidden gems of Greece - untouched by the big tourist crowds. Alonissos is close to the island of Skiathos, which is much more famous, but the atmosphere here is very different. Alonissos is calmer, greener, and known for its protected marine park.

The easiest way to get here is via Skiathos. From Athens you can fly to Skiathos in about 40 minutes and then take a ferry to Alonissos, which usually takes around two hours. There are also ferry connections from mainland ports like Volos and Agios Konstantinos if you prefer traveling entirely by sea.

The island is pretty much a nature lover’s dream. You’ve got rugged hills, crystal-clear waters, and little stone villages that make you feel like you’ve stepped into another time. Plus, the National Marine Park of Alonissos is home to the rare Mediterranean monk seal, so if you’re into wildlife, you might even catch a glimpse of these adorable creatures while diving or boating.

Once you get to Patitiri, the main town, you’ll instantly feel like you’ve entered a peaceful little world. It’s quiet, with whitewashed houses and narrow streets to wander through. If you’re in the mood to dive into the island’s past, pop into the Alonissos Museum - it’s a great spot to get a feel for the island’s maritime history.

For some serious chill time, head to Agios Petros Beach. It’s one of the more remote spots on the island, so you can escape the crowds and just relax with the sound of the waves. Trust me, it’s the perfect place to lay back and recharge.

When it comes to where to stay, Alonissos Beach Hotel & Spa is the way to go. It’s right on the water, so you can wake up to views that make you feel like you’re in a dream. After a day of exploring, this is the perfect spot to unwind.

If you're in the mood for some seriously good food on Alonissos, Tassia's Cooking in Steni Vala is a must-visit. This cozy family-run taverna is tucked right by the harbor, offering a relaxed vibe with stunning views. The menu is packed with fresh, traditional Greek dishes, and everything is made with love: especially the seafood. You’ll find classics like grilled fish, fried cheese pies, and lamb cooked with lemon, all served in generous portions. It’s the kind of place where you feel like you're eating at a friend's house, with the bonus of a gorgeous view of the water.

The atmosphere is super friendly and laid-back, making it perfect for a leisurely lunch or a sunset dinner. Honestly, it's one of those spots that makes you fall in love with the island all over again. So, if you’re looking for authentic, mouthwatering Greek food with a cozy, welcoming feel, Tassia's Cooking is where you want to go. Trust me, you won’t regret it!

Alonissos is all about slow living. It’s quiet, beautiful, and just what you need if you want to escape the hustle and take in the beauty of Greece at a slower pace.

Tilos: An Eco-Friendly Island with Authentic Charm

Tilos is a small island in the Dodecanese, located between Rhodes and Kos in the southeastern Aegean. The island’s reputation for sustainable tourism has kept it under the radar, but that’s exactly why it’s such a gem. Tilos is actually one of the quietest and most eco-conscious Greek islands. Tilos is a perfect blend of natural beauty and authentic Greek life, offering sweeping hillsides, dramatic cliffs, and pristine beaches.

Compared to its larger neighbours, it receives only a small number of visitors each summer, which is exactly why many people fall in love with it.

Most travelers reach Tilos via Rhodes. After flying from Athens to Rhodes (about one hour), you can continue by ferry, which usually takes around two hours. There are also ferry connections from nearby islands like Kos and Symi. Because most visitors stay in Rhodes, Tilos has managed to keep a much slower pace.

If you love nature, Tilos will steal your heart. The island is a hiker’s dream, with rugged hills and ancient paths winding through olive groves, past old stone houses, and leading to peaceful beaches. Many visitors walk from Livadia up to the abandoned medieval village of Mikro Chorio, which sits on a hillside above the coast and has beautiful sunset views. It’s this hauntingly beautiful place where nature has crept back in, with wildflowers growing through cracks in the old stone walls. It’s one of those places that feels timeless, and it’s perfect for a quiet stroll.

The beaches here are exactly what you need for a slow, relaxing day. Livadia Beach is just a short walk from the main town, offering calm, clear waters and a laid-back vibe. But if you’re craving something a little more secluded, Agios Stefanos Beach is a true gem: perfect if you want a quiet spot to unwind and feel like you’ve discovered your own secret piece of paradise.

What I love about Tilos is that it’s still so connected to nature. The island is home to a variety of wildlife, and if you're lucky, you might spot the rare Tilos butterfly. The National Park here is a great spot for nature lovers, and it’s a real treat for anyone looking to escape the more tourist-heavy spots in Greece.

As for where to stay, there are some cozy, family-run guesthouses that are perfect for getting that true island experience. Everything here feels personal and easygoing. And when it comes to food, To Delfini is the spot to go for fresh seafood and traditional Greek dishes. It’s right by the water, and the vibe is relaxed and welcoming, just like the island itself.

Tilos is all about slow living: there’s no rush, just the chance to enjoy the natural beauty, peaceful beaches, and delicious food. It’s perfect for anyone looking for an authentic, quiet getaway where you can truly disconnect, recharge, and enjoy a slower pace of life. If you’re craving a real escape from the hustle and bustle, Tilos is exactly what you need.

Tinos really is a Cycladic island that still feels surprisingly local. If you’re curious, I wrote more about spending a summer on Tinos here.

Folegandros: A Timeless, Enchanting Island

Finally, let’s talk about Folegandros: a tiny island that’s managed to stay refreshingly unspoiled despite its beauty. If you're craving a place that feels authentic and untouched, Folegandros is perfect for you. It’s the kind of island where you can really slow down and soak in the simplicity of life. You’ll find yourself walking through narrow, cobbled streets, surrounded by whitewashed houses with flowers spilling over the edges. It’s the kind of place where time seems to slow down, and you’ll be greeted by the warmest locals who are always happy to share a story or recommendation.

Folegandros is part of the Cyclades islands and sits between Santorini and Milos in the southern Aegean. Even though it’s close to some of Greece’s most famous destinations, it feels much quieter and more traditional.

From Athens, ferries leave from the port of Piraeus and reach Folegandros in around four to five hours. Another option is flying from Athens to Santorini and then taking a short ferry to Folegandros, which usually takes about an hour. Many travelers visiting Santorini never make it this far, which is one of the reasons the island still feels relaxed. The journey is smooth, and when you arrive, you’ll immediately fall in love with Chora, the island's charming capital. This village is perched high on a hilltop, offering jaw-dropping panoramic views of the Aegean Sea. As you wander through its narrow streets, you’ll come across whitewashed homes, cute cafés, and little boutiques tucked into the corners. It’s the perfect place to wander aimlessly, or just sit back and enjoy a coffee while taking in the sights.

For beach lovers, Agali Beach is a must-visit. It’s the kind of beach where the water is so clear, you can see straight to the bottom. The vibe here is calm and peaceful, just the sound of gentle waves and the occasional seabird flying by. It’s the perfect spot to lay down your towel, enjoy the sun, and take a refreshing dip in the crystal-clear waters. If you want to find your own little slice of heaven, take the path to Katergo Beach. It’s a more secluded spot that requires a bit of a hike or a boat ride, but trust me - it’s worth it. The view from the beach at sunset is absolutely magical. Watching the sun dip below the horizon while the sky fills with golden hues is the kind of moment that makes you feel like you’re in a dream.

When it comes to accommodation,If you’re looking for a cozy, charming place to stay on Folegandros, Anemomilos Boutique Hotel is perfect. This family-run gem is just a short walk from the heart of Chora, and it offers some of the best views on the island. The rooms are simple but beautifully designed, with whitewashed walls, blue shutters, and cozy terraces where you can enjoy the sunset. The vibe here is laid-back, with a pool to cool off after a day of exploring and a poolside bar for evening cocktails. It’s the ideal spot for anyone looking to unwind, enjoy some peace, and soak in the beauty of Folegandros!

For a true local experience, To Spitiko in Chora is a cozy, family-run taverna you’ll love. It’s the perfect spot to try traditional Greek dishes made with fresh, local ingredients. The vibe is super relaxed, and the food? Absolutely delicious.

Another great option is Zefyros, also in Chora. It has a lovely outdoor courtyard and a welcoming atmosphere, serving up Mediterranean dishes that’ll make you want to come back for more. Both places really capture the authentic spirit of Folegandros, so you’re in for a treat!

Folegandros is one of those islands that feels timeless. It’s a place where you can take your time, savor the moments, and enjoy the simple things like an afternoon stroll, a fresh seafood meal, or catching the perfect sunset. If you're looking to connect with nature, unwind in peace, and experience authentic Greek life, Folegandros should be at the top of your list.

Greece will probably always be associated with Santorini and Mykonos, but the country’s smaller islands often leave the strongest memories. Places like Kythira, Alonissos, Tilos, Kastellorizo, and Folegandros offer a slower kind of island travel - the kind where mornings start with coffee by the harbor and evenings end in a village square.

If you enjoy places where life still revolves around a village square or small harbor, you might also like exploring some of the quietest villages in Europe, especially outside peak travel season.
