Beyond Santorini: Greece's Hidden Islands Trending for 2026

Santorini is magnificent. The caldera views, the white-and-blue architecture cascading down volcanic cliffs, the sunsets that stop you mid-sentence — it all deserves its reputation. But Santorini in peak season has also become something else: crowded, expensive, and increasingly difficult to enjoy at the pace that Greek island life is supposed to offer.

A growing number of travelers are discovering what Greeks have always known: the country has over 6,000 islands, roughly 200 of which are inhabited, and many of them deliver experiences that rival or surpass the famous names — at a fraction of the cost and without the crushing crowds. Euronews recently named Skopelos and Andros among the "surprise destinations" for 2026, and they are just the beginning.

This is your guide to the Greek islands that deserve your attention this year, the ones where you can still find an empty beach, a taverna where the owner remembers your name, and a sunset you do not have to share with a thousand other tourists.

Skopelos: The Mamma Mia Island

Skopelos earned global fame as the filming location for Mamma Mia, but it somehow avoided the tourist avalanche that such exposure usually brings. The island remains remarkably unspoiled, covered in dense pine forests that extend almost to the waterline, giving it a lush, green character unlike the arid Cycladic islands.

The main town, Skopelos Town, climbs a hillside above the harbor in a cascade of whitewashed houses with slate roofs and flower-filled balconies. The atmosphere is genuinely relaxed. Restaurants serve fresh fish caught that morning, and the pace of life revolves around long lunches, afternoon swims, and evening strolls along the waterfront.

The island's beaches are its greatest asset. Kastani Beach, where key Mamma Mia scenes were filmed, is a beautiful cove backed by pines. Stafylos and Velanio offer excellent swimming with fewer people. The iconic Agios Ioannis chapel, perched on a dramatic rock above the sea, is the spot where the movie's wedding scene was filmed — and it is just as striking in person as it was on screen.

Getting to Skopelos involves a ferry from the neighboring island of Skiathos, which has a small airport with seasonal flights from several European cities, or a longer ferry from the mainland port of Volos. The extra step of getting there is precisely what keeps the crowds manageable.

Accommodation ranges from simple family-run studios at 40 to 60 euros per night to charming boutique properties at 80 to 150 euros. Dining is excellent and affordable — a full taverna meal with wine rarely exceeds 20 euros per person.

Andros: The Hiking Capital of the Cyclades

Andros is the closest Cycladic island to Athens, reachable by a two-hour ferry from Rafina port, yet it feels worlds apart from the Cycladic mainstream. While Mykonos and Santorini built their identities around nightlife and luxury, Andros built its around nature, art, and walking.

The island has over 160 kilometers of marked hiking trails, many following ancient paths that connected villages across the mountainous interior. The Andros Route, a network of restored trails, is one of the best hiking experiences in Greece. Paths wind through terraced valleys, past Byzantine churches, along stone walls, and through landscapes where the only sound is wind and birdsong.

Andros Town, the capital, sits on a narrow peninsula jutting into the sea. It has an unexpectedly sophisticated cultural scene, with the Museum of Contemporary Art and the Archaeological Museum both worth visiting. The main street is lined with neoclassical mansions, a legacy of the island's wealthy shipping families.

The beaches are excellent and rarely crowded. Achla Beach, accessible only by boat or a hiking trail, is consistently ranked among Greece's best. Tis Grias to Pidima, with its distinctive rock formation rising from the sea, is another standout.

Andros also has a notable waterfall, Pythara, set in a green gorge — a rarity on the typically dry Cycladic islands. The island's water abundance supports a lush landscape that distinguishes it from its neighbors.

For travelers who value active exploration over passive relaxation, Andros is arguably the best island in the Cyclades.

Milos: The Volcanic Wonder

Milos has gained considerable attention in recent years, and for good reason. The island's volcanic geology has created a coastline of extraordinary variety — sea caves, multicolored rock formations, and over 70 beaches, each with a distinct character. Sarakiniko, with its lunar-white rock formations sculpted by wind and waves, is one of the most photographed spots in Greece.

Kleftiko, accessible only by boat, features towering white cliffs, sea caves, and crystal-clear water that shifts between turquoise and deep blue. A boat trip around Milos is one of the quintessential Greek island experiences, and the volcanic formations make it genuinely unique.

The fishing village of Klima, with its colorful boathouses built into the rock at water level, is impossibly photogenic. The main town of Plaka offers panoramic sunset views from the castle ruins that rival anything on Santorini — without the crowds.

Milos is more developed for tourism than Skopelos or Andros, with a wider range of accommodation and dining options. It has found a sweet spot between accessibility and authenticity that makes it ideal for travelers who want comfort without the feeling of being on a tourist conveyor belt. Prices are moderate — roughly 30 to 40 percent less than Santorini for comparable quality.

Naxos: The Largest and Most Diverse

Naxos is the largest of the Cycladic islands, and its size gives it a diversity that smaller islands cannot match. The western coast has long sandy beaches that are among the best in Greece — Agios Prokopios, Agia Anna, and Plaka stretch for kilometers. The mountainous interior holds traditional villages like Halki and Apiranthos, where marble-paved streets wind between Venetian-era towers.

Mount Zeus (Zas), the highest peak in the Cyclades at 1,004 meters, offers a rewarding hike with views across the entire island chain. The summit, according to mythology, is where Zeus spent his youth — not a bad place to grow up.

Naxos Town has a lively harbor dominated by the iconic Portara, a massive marble doorway that is all that remains of an unfinished temple of Apollo. The old town is a maze of Venetian-era alleys, and the dining scene is excellent, with a strong emphasis on local products — Naxos potatoes, graviera cheese, and kitron liqueur made from citron fruit.

For families and travelers who want variety within a single island, Naxos is hard to beat. It combines beaches, hiking, culture, and cuisine in a package that keeps you engaged for a week or more.

Lefkada and Ikaria: The Outliers

Two more islands deserve mention for travelers willing to venture further from the beaten path.

Lefkada, in the Ionian Sea off Greece's western coast, is unique among the islands because it is connected to the mainland by a causeway — no ferry required. Its western coast features some of the most dramatic beaches in the Mediterranean. Porto Katsiki, with its towering white cliffs and turquoise water, is breathtaking. Egremni, accessible by a long staircase, offers a wilder experience. The island is also a world-class windsurfing and kitesurfing destination, with Vassiliki Bay drawing enthusiasts from across Europe.

Ikaria, in the eastern Aegean, is famous for a very different reason: it is one of the world's five Blue Zones, where residents live measurably longer than the global average. The island's culture of community, diet, daily movement, and relaxed attitude toward time has been extensively studied. Visitors come for the springs, the hiking, and the panigiria — traditional festivals that run through the summer with music, dancing, and communal feasting that lasts all night.

Ikaria operates on its own clock. Shops open when the owner feels like it. Dinner starts late. The bus might come, or it might not. For travelers willing to surrender their schedules and go with the flow, it is one of the most restorative places in Greece.

Island-Hopping Logistics

One of the great pleasures of Greek travel is combining multiple islands into a single trip. The ferry network is extensive, and with some planning, you can create routes that are both efficient and varied.

A practical Cycladic itinerary might start in Athens, ferry to Naxos for four nights, continue to Milos for three nights, and return to Athens. For the Sporades, fly to Skiathos, ferry to Skopelos for four nights, and return via Skiathos. Combining Andros with Tinos and Naxos makes geographic sense within the Cyclades.

Ferry schedules are published online, and booking platforms like Ferryhopper and Direct Ferries make reservations straightforward. During peak season, advance booking is advisable for popular routes — deck-class tickets are rarely an issue, but cabin berths and car spaces can sell out.

Real-time ferry tracking, schedule updates, and booking confirmations all require mobile data. Having a working connection from the moment you arrive in Greece makes the logistics of island-hopping significantly smoother. Weather-related schedule changes are common in the Aegean, and getting notifications on your phone beats standing at the port hoping for information.

Staying Connected Across the Greek Islands with eSimphony

Greek mobile networks provide solid 4G coverage across all inhabited islands, including the smaller and more remote ones. Towns, ports, and popular beaches have reliable signal. Coverage can thin in mountainous interiors, but for the vast majority of island activities, connectivity is not an issue.

For travelers hopping between islands, the last thing you want is connectivity disruption. An eSimphony Greece plan or Europe regional plan keeps your data working seamlessly across every island and the mainland. Open the eSimphony app before your trip, choose your plan, and tap Install. When you land in Athens or step off the ferry on your first island, your data is active.

The practical benefits are immediate. Navigate unfamiliar island roads with real-time maps. Check ferry schedules and get alerts about delays. Book restaurants and accommodation on the next island while sitting on the beach of the current one. Translate a menu at a taverna where no one speaks English. Share photos and updates with friends and family without hunting for cafe Wi-Fi.

For a two-week Greek island trip, 8 to 15 GB of data covers most travelers' needs. If you plan to work remotely or stream content, a larger plan gives you the headroom. Moza, the AI assistant in the eSimphony app, can recommend the right plan based on your specific itinerary and usage habits. She can also suggest downloading offline maps for islands where you plan to hike in areas with limited signal.

Greece's hidden islands offer something that the famous names increasingly struggle to deliver: the feeling of genuine discovery. Empty beaches, unhurried meals, conversations with locals, and the simple pleasure of being somewhere beautiful without being part of a crowd. These islands are trending for 2026 because travelers are realizing that the best of Greece was never limited to two or three famous names — it was always spread across an archipelago of thousands, waiting to be explored. Get your connectivity sorted, pack light, and go find your island.
