10 Hidden Islands of Greece

Greece is full of small islands that barely appear on the map — quiet, untouched places where you can escape the tourist crowds. The easiest way to reach them is by chartering a yacht in Greece.

From the sea, you’ll see fishing villages and rugged coastlines, where you can relax to the rhythm of the waves and feel the calm pace of Greek island life.

AnyDay Charter has selected ten of Greece’s most beautiful hidden islands that promise unforgettable impressions.

The easternmost island of Greece, located close to the Turkish coast.

The route is ideal for peaceful sailing and short passages. Onshore, you can stop at a small café and stroll along the promenade. Around the island, you’ll find rocky bays and the famous Blue Cave. Summer temperatures average around +28°C, and 22–25°C in spring and autumn.

Tip: Supplies like fuel and water can be hard to find on Kastellorizo, so stock up before you arrive — the infrastructure is limited.

Situated between Samos and Ikaria, this group of small islands features quiet harbors and fishing villages. It’s rarely crowded, which makes it perfect for unwinding and enjoying solitude.

Summer can be hot — around +29°C in July, and about +23°C in spring.

It’s a great spot for anchorage and swimming. The coastal tavernas offer authentic Greek dishes, and the clear waters are ideal for snorkeling. Watch out for underwater rocks as you approach.

A small island in the Dodecanese, known for its transparent waters and secluded coves. It will feel familiar to anyone who has experienced yacht charters in Turkey.

It’s perfect for relaxed sailing — weather is usually calm. When anchoring near Lipsi, check the depth, as some bays have uneven seabeds.

Average summer temperatures are about +27°C, and the sea warms up for swimming by June.

Onshore, visit the Church of Panagia Harou and local wineries. In the evening, it’s pleasant to stay anchored near Papa Beach. Between Lipsi and Patmos, you’ll find short and scenic routes suitable for day trips.

A quiet Cycladic island with rugged cliffs, white rocks, and minimal tourism. Gentle breezes and the sound of the sea create a peaceful atmosphere. Temperatures reach +28–29°C in summer with mild winds.

Visit the island’s beaches and rocky shores. Morning departures are most comfortable — the sea is calmer, and the wind lighter.

The smallest of the Lesser Cyclades, with few residents and a simple coastline. There are a handful of small bays perfect for swimming and exploring the Cave of St. John.

Average temperatures hover around +26°C, and winds are weak.

Tip: The local port is tiny, so plan to anchor in a sheltered bay.

A volcanic island with a diverse shoreline of caves, cliffs, and sandy beaches. The western coast is less developed, so keep that in mind when mooring.

Summer temperatures reach around +27°C, with the season lasting from May to October.

You can moor comfortably in Adamas Port, and on clear days, sail around the island, stopping in coves like Sarakiniko and Kleftiko.

A small island across from Paros, famous for its quiet beaches. The infrastructure is limited — unlike yacht charters in Croatia, where marinas are fully equipped, Greece offers more unspoiled, tranquil places.

The island is perfect for short stops as part of a Cyclades route. On the Despotiko side, the water is calmer, and the seabed is ideal for anchorage.

Summer temperatures reach about +29°C, with a mild, steady climate.

Visit the famous Antiparos Cave and spend time at the harbor near the old port.

An island rich in culture and moderately popular with tourists. It offers comfortable bays, good sailing conditions, and traditional villages with classic Cycladic architecture.

Temperatures in summer stay around +27°C, and the winds are predictable.

Walk the paths between Kamares and Apollonia, visit artisan workshops, and try local cuisine. Vathy Bay is one of the best-protected night anchorages.

A cultural gem of the Cyclades, known for the Church of Panagia Evangelistria and its charming villages. The sea here is calm, and navigation is easy.

Summer temperatures average +26°C, and the season is long and warm.

It’s a great island for leisurely walks, exploring pottery workshops, and enjoying seaside tavernas. Bring a camera if you plan to capture the scenery or film your journey.

Tip: Avoid anchoring on the exposed north side — winds there can be strong. We’ve also prepared an article on how to read and understand the wind when sailing.

Part of the Dodecanese, Symi is known for its neoclassical architecture and calm harbor. The port of Symi is beautifully arranged and well protected.

Summer temperatures hover around +28°C, and the sea stays warm until late September.

Spend the day in the harbor or explore small coves along the southern coast. Symi is often included in charters from Rhodes — just a few hours’ sail away, making it ideal for a shortstop.

Tip: Docking space is limited, so plan to arrive early.

Island-hopping is relaxing, but it still requires preparation.

Here’s what we recommend taking:

• Light spring-summer clothing: shorts, T-shirts, a windbreaker, and a sun hat. Bring sweaters for autumn.

• Non-slip shoes for the deck and sandals for walking ashore.

• As with yacht rentals in Italy, bring sunscreen, sunglasses, and a high-SPF lotion.

• A small first aid kit with plasters, antiseptics, and motion sickness tablets.

• Chargers and a waterproof phone case.

These essentials will make your trip more comfortable and safe. If you’re traveling with a pet, pack their necessary medications.

Sailing through Greece’s lesser-known islands is a chance to experience the country without crowds and discover untouched nature. Each island has its own charm, and the routes between them encourage slow travel — explore at your own pace, whether alone or with your family.
