4. Rhodes, the island of knights and sun

Rhodes, the largest island of the Dodecanese, enjoys more than 300 days of sunshine per year, which earns it the nickname of the island of the sun. The medieval old town of Rhodes, inscribed on the UNESCO World Heritage List, constitutes one of the best preserved medieval ensembles in Europe. Surrounded by impressive ramparts, it was the stronghold of the knights of the Order of Saint John of Jerusalem in the Middle Ages.

The geological phenomena of Cephalonia fascinate visitors. The Katavothres sinkhole, where seawater mysteriously engulfs into cavities to resurface on the other side of the island, constitutes a unique natural curiosity.

This small island of the Saronic Gulf has made the radical choice to ban cars and motorcycles from its territory, thus preserving a unique atmosphere and precious calm. Travel is done on foot, by donkey or by water taxi along the coasts. This particularity gives Hydra an old-fashioned charm that has seduced numerous artists, writers and personalities from around the world.

Hydra's port, crescent-shaped, offers a theatrical setting with its 18th-century captains' houses climbing the rocky hills. These imposing stone houses, with sumptuously decorated interiors, testify to the maritime prosperity the island knew at that time. Several of these archontika (masters' houses) can be visited, like the Lazaros Koundouriotis house transformed into a museum. Hydra's beaches are mainly rocky and accessible by coastal paths or water taxi. Vlychos, Kaminia and Mandraki offer quiet coves with a few traditional taverns with their feet in the water. In summer, Hydra comes alive during cultural festivals and art exhibitions that reinforce its reputation as a cosmopolitan and refined island, where the Athenian intelligentsia likes to gather away from urban bustle.

14. Folegandros, the preserved secret of the Cyclades

Folegandros embodies the preserved authenticity of the Cyclades, far from the mass tourism that has transformed some of its neighbors.

The Chora of Folegandros is among the most beautiful of the Cyclades, spectacularly clinging to the edge of a cliff nearly 200 meters high. Its three squares connected by paved alleys invite strolling in a relaxed atmosphere where time seems suspended.

18. Skyros, the authentic island of the Sporades

Skyros, the largest and southernmost of the Sporades islands, remains unknown to classic tourist circuits, thus preserving rare authenticity. The island divides into two distinct parts: the verdant and fertile north covered with pines and olive trees, and the arid and mountainous south of wild beauty. This geological duality is also reflected in the unique local culture that mixes Cretan, Byzantine and Venetian influences. The Chora of Skyros, built in amphitheater on a rocky spur dominated by a Venetian kastro and a Byzantine monastery, offers a remarkable example of Cycladic architecture with its white cubic houses climbing the hill.

The paved alleys reveal small shaded squares and craftsmen perpetuating traditional know-how, notably the manufacture of carved miniature furniture and colorful decorative pottery.

20. Ikaria, the island of longevity

Ikaria has acquired worldwide renown as one of the 'blue zones' of the planet, these regions where life expectancy far exceeds the world average. A third of Ikaria's inhabitants reach the age of 90, a phenomenon attributed to the traditional way of life, local diet rich in vegetables, wild herbs and olive oil, as well as a relaxed pace of life where stress seems absent. This island of the eastern Aegean Sea takes its name from Icarus, the mythological character who fell into the sea after flying too close to the sun with his wax wings.

FAQ: The Most Beautiful Greek Islands

What is the best time to visit the Greek islands?

The ideal period to visit the Greek islands extends from May to October, with a preference for May-June and September-October to avoid crowds and excessive heat of July-August. The months of May and June offer pleasant temperatures around 25°C, more attractive prices and vegetation still green. September and early October benefit from a warm sea after summer and a calmer ambiance with the departure of summer vacationers. July and August, while guaranteeing maximum sunshine and a sea at perfect temperature, experience significant tourist affluence and high prices, particularly on the most popular islands like Santorini and Mykonos.

How to travel between the Greek islands?

The ferry network is the most used means to navigate between the Greek islands. Companies like Blue Star Ferries, Seajets or Hellenic Seaways ensure regular connections between islands, with classic ferries that are slower and more economical, or fast catamarans that are more expensive. It is recommended to book in advance in high season. Some islands have airports allowing domestic flights from Athens or Thessaloniki, a faster but more expensive solution. The main islands with airports are Santorini, Mykonos, Rhodes, Kos, Corfu, Zakynthos, Crete and a few others. To optimize your itinerary, prioritize islands from the same archipelago, as connections are more frequent and direct there.

How many islands should you plan to visit during a trip to Greece?

For a first trip of one to two weeks, it is advised to concentrate on two to four islands maximum in order to fully enjoy each one without spending your time in transportation. A stay of 10 to 14 days allows for example to comfortably combine three Cyclades islands (Santorini, Mykonos and Naxos or Paros) with a few days in Athens. For a longer trip of three weeks, you can consider four to five islands by varying the archipelagos. Keep in mind that each ferry transfer takes time (between 1h and 6h depending on distances), and that it is preferable to stay at least three nights on each island to really discover its atmosphere and main sites without constantly being in your luggage.

Which Greek islands to choose for family holidays?

For family holidays with children, prioritize islands offering sandy beaches with shallow waters, adapted infrastructure and less steep terrain. Naxos constitutes an excellent choice with its long fine sand beaches, picturesque villages and authentic character. Paros also offers beautiful family beaches and good tourist infrastructure without being too crowded. Corfu, with its luxuriant vegetation and varied beaches, generally pleases children. Rhodes offers an excellent combination of history, beaches and activities like the aquarium or water parks. Crete, by its size, allows varying activities between beaches, accessible archaeological sites like Knossos, and gorges adapted to family hikes. Avoid very steep islands like Santorini or very festive ones like Ios for a stay with young children.

What are the least touristic Greek islands?

To escape crowds and discover authentic Greece, orient yourself towards islands like Folegandros in the Cyclades, which has managed to preserve its traditional character. Ikaria, with its unique way of life and reputation as the island of longevity, attracts few conventional tourists. Alonissos in the Sporades offers preserved nature and quality ecotourism far from mass tourism. Samos, despite its proximity to Turkey and historical heritage, remains relatively little frequented. Skyros, the southernmost island of the Sporades, preserves its authenticity thanks to its relative isolation. Amorgos, Sikinos, Anafi in the Cyclades, or Kassos and Karpathos in the Dodecanese feature among the authentic islands where you will discover traditional Greek island life, far from the tourist bustle of Santorini or Mykonos.
