12 Secret Islands in Greece to Avoid the Crowds

Myth vs. Reality: The Truth About Crowding in the Greek Islands

The global perception of the Greek summer is often defined by the sun-bleached, blue-domed churches of Santorini or the high-energy beach clubs of Mykonos. However, according to data from the Hellenic Statistical Authority (ELSTAT), over 75% of international arrivals to the Aegean islands are concentrated in just a handful of highly commercialized destinations. This leaves dozens of pristine islands virtually untouched by mass tourism.

While popular social media channels suggest that finding an empty beach in Greece during July and August is impossible, the reality is far more encouraging. By stepping off the standard ferry routes, travelers can experience the authentic, slow-paced Mediterranean lifestyle that first drew writers and artists to these shores decades ago. In these secluded havens, the water is crystal clear, the tavernas are family-run, and the hospitality (philoxenia) remains a genuine cultural value rather than a commercial transaction.

The 12 Best Secret Greek Islands

1. Folegandros: The Dramatic Cliffside Alternative to Santorini

Folegandros offers the same jaw-dropping volcanic topography as its famous neighbor, Santorini, but without the cruise ship crowds. The island’s capital, Chora, is built on the edge of a sheer 200-meter cliff, offering sweeping views of the Aegean Sea. Visitors can walk up the zigzagging stone path to the Church of Panagia, which dominates the hillside, particularly spectacular at sunset.

How to get there: Folegandros does not have an airport. You can reach it via a 4-to-6-hour ferry ride from Athens (Piraeus) or a shorter 45-minute high-speed ferry from Santorini. Check schedules on Ferryhopper.

Hyper-local insight: The Chora of Folegandros is entirely pedestrianized. To experience the ultimate quiet, visit the squares of Chora around 11:30 AM when day-trippers have not yet arrived, and enjoy a traditional plate of matsata (handmade local pasta served with rooster or rabbit) at a quiet corner taverna.

2. Anafi: The Untouched Cycladic Escape

Anafi is a rugged, cone-shaped island located just east of Santorini. It remains one of the most isolated islands in the Cyclades, characterized by its wild landscapes and pristine, unorganized beaches like Roukounas. The island has only one major settlement, Chora, where traditional stone houses cling to the hillside beneath a Venetian castle ruin.

History vs. Legend: The Argonauts' Sanctuary

Safety & Respect Disclaimer: When hiking around Mount Kalamos or visiting remote chapels after dark, always carry a reliable flashlight, wear sturdy shoes, and respect the quietude of these spiritual sites. Do not leave trash or disturb the ancient stone structures.

3. Iraklia: The Small Cyclades Sanctuary

Part of the Lesser Cyclades, Iraklia is a tiny island of fewer than 150 permanent residents. It is a haven for hikers and those seeking complete peace. The island has two main villages: Agios Georgios (the port) and Panagia. Iraklia is famous for its dramatic caves, particularly the Cave of Saint John, and its untouched beaches like Alimia, where a sunken World War II plane is visible to snorkelers.

How to Get There: Take the legendary local ferry, the Express Skopelitis, from Naxos, or board a direct ferry from Piraeus, which runs several times a week.

Hyper-local insight: There are no banks or fuel stations on Iraklia. Ensure you withdraw cash in Naxos or Athens before departing, and arrange any scooter or car rentals well in advance during peak season.

4. Sikinos: The Wine-Rich Haven

Sikinos is one of the most low-key islands in the southern Cyclades, situated between Ios and Folegandros. It has successfully resisted major tourism development, preserving its traditional agriculture, stone-paved pathways, and terraced hillsides. The island is highly regarded for its wine production, a tradition dating back to antiquity when the island was known as Oinoe (Island of Wine).

Key Attraction: The Manalis Winery offers organic wine tastings on a terrace overlooking the sea. Visitors can also explore the Episkopi, a unique monument that was recently restored—a 3rd-century Roman mausoleum converted into a Byzantine church.

5. Lipsi: The Dodecanese Eco-Paradise

Located in the northern Dodecanese, Lipsi is a cluster of small islands with a strong focus on sustainable development and environmental protection. The local municipality has actively discouraged the development of organized sunbeds and umbrellas on its beaches, encouraging a natural, eco-friendly beach experience. The main town features a picturesque harbor lined with blue-and-white tavernas serving fresh seafood.

Local Culinary Treat: Lipsi is famous for its sweet black wine, Fokiano, and its exceptionally fresh octopus, which is sun-dried on lines along the harbor before being grilled over charcoal.

6. Kastellorizo: The Far-Eastern Gem

Kastellorizo (officially Megisti) is the easternmost island of Greece, located just two kilometers off the southern coast of Turkey. The island is famous for its pastel-colored, neoclassical mansions that ring the deep-water harbor, a stark contrast to the typical whitewashed Cycladic architecture. Kastellorizo has no beaches; instead, visitors dive directly into the deep, clear harbor water or take taxi boats to the spectacular Blue Grotto, one of the largest sea caves in the Mediterranean.

How to Get There: Kastellorizo has a small airport with daily flights from Rhodes, as well as regular ferry connections from Rhodes and Piraeus.

7. Alonissos: The Marine Park Sanctuary

Alonissos is the quietest of the Sporades islands, characterized by its dense pine forests, olive groves, and pebble beaches. The island is home to the National Marine Park of Alonissos and Northern Sporades, the largest marine protected area in Europe. This park is a critical habitat for the endangered Mediterranean monk seal (Monachus monachus).

For Divers: Alonissos features the spectacular underwater museum of Peristera, where divers can explore a 5th-century BC shipwreck containing thousands of ancient amphorae. For non-divers, the Information Center in Patitiri offers virtual reality tours of the wreck.

8. Kythira: The Island of Aphrodite

Located at the junction of the Aegean, Ionian, and Cretan seas, Kythira is a large but remarkably quiet island with a diverse landscape of gorges, waterfalls, medieval castles, and pristine beaches. Its architecture is a unique blend of Venetian, Ionian, and Aegean styles.

History vs. Legend: The Birth of Love

According to ancient Greek mythology and Hesiod's Theogony, Kythira is the birthplace of Aphrodite, the goddess of love, who emerged from the sea foam here before traveling to Cyprus. Historically, the island was a strategic maritime crossroads, ruled successively by the Spartans, Romans, Byzantines, Venetians, and British, leaving behind a rich archaeological heritage.

9. Ithaca: The Mythological Home of Odysseus

Ithaca, located in the Ionian Sea, is synonymous with home, perseverance, and adventure. Separated from Kefalonia by a narrow channel, Ithaca features lush, green hillsides that drop steeply into deep, sheltered bays. The island’s capital, Vathy, sits inside a fjord-like bay and features colorful Venetian-style houses.

Must-Visit: The Kathara Monastery, located at the island's highest point, offers panoramic views of the entire Ionian archipelago. Hikers can also explore the Cave of the Nymphs, where legend says Odysseus hid his treasures upon returning from Troy.

10. Amorgos: The Deep Blue Island

Amorgos is the easternmost of the Cyclades islands, famous for its dramatic mountain ridges and deep blue waters, which inspired Luc Besson's 1988 film The Big Blue. The island's crowning jewel is the Monastery of Panagia Hozoviotissa, a 10th-century structure built directly into the face of a sheer cliff 300 meters above the sea.

Traveler Tip: Dress respectfully when visiting the monastery (long trousers for men, long skirts and covered shoulders for women). The monks frequently welcome visitors with a glass of local psimeni raki (a warm, spiced grape spirit with honey and cloves) and a piece of Turkish delight.

11. Donoussa: The Remote Cycladic Outpost

Donoussa is another gem of the Lesser Cyclades, situated north of Amorgos. It is small enough to explore entirely on foot, with a network of ancient donkey paths connecting its five small villages. The island is highly favored by wild campers, hikers, and those seeking an uncomplicated beach holiday on soft golden sands like Kedros and Livadi.

Getting Around: There are very few cars on Donoussa. During the summer, a small local boat runs daily trips from the main port of Stavros to the island's more remote beaches.

12. Kasos: The Authentic Dodecanese Maritime Hub

Kasos is the southernmost island of the Dodecanese, located near Crete. It is an island of rugged landscapes, deep-rooted musical traditions (featuring the lyre and lute), and a proud maritime history. Kasos remains almost entirely untouched by international tourism, preserving its authentic local culture and culinary heritage.

Food Highlight: Try makarounes (local pasta) served with sitaka, a creamy, slightly sour local goat and sheep cheese, or soupiopilafo (cuttlefish risotto cooked in its own ink).

Planning Your Trip: Essential Logistics & Practicalities

Planning a trip to Greece's lesser-known islands requires careful preparation, as transport links are less frequent and local infrastructure is more modest than on the major islands.

Pros & Cons of Secret Greek Islands

• Pros: Uncrowded beaches, lower prices for dining and lodging, authentic cultural interactions, preserved natural environments, and a peaceful atmosphere.
• Cons: Longer and less frequent ferry connections, limited luxury amenities, fewer English-speaking services in remote areas, and limited medical facilities.

Best Time to Visit

Additionally, you will avoid the peak heat of mid-summer.

Budget Estimations

Based on cost-of-living estimates for rural Greece, a budget traveler can expect to spend approximately €50 to €80 per day (including hostel/budget room, local meals, and ferry transport).
