Scattered across the edges of the Aegean and Ionian Seas are Greece’s most remote islands; places that sit far from major ferry routes, often closer to Crete than to Athens. These outliers offer a different kind of travel experience: slower, quieter, and deeply tied to local rhythms. Some have only a few hundred residents; others are shaped by volcanic terrain, monastic heritage, or maritime isolation.
This guide highlights Greece’s outlying islands: from pine‑covered Agistri and barefoot Elafonisos to Europe’s southernmost Gavdos. Each profile shows what makes these islands distinctive and how they fit into a broader itinerary for travelers seeking depth, solitude, and authenticity.

Outlier Greek Islands at a Glance
- Agistri: A pine‑covered Saronic Gulf island less than an hour from Athens, Agistri is ideal for swimming, cycling, and weekend escapes.
- Antikythira: Perched between Crete and Kythira, this windswept speck is a paradise for birdwatchers and history lovers, with ancient shipwrecks and a population of barely 50.
- Elafonisos: Known for Simos Beach and its turquoise waters, Elafonisos offers a laid‑back Peloponnesian detour with a barefoot, summer‑holiday vibe.
- Gavdos: Europe’s southernmost inhabited island, Gavdos is all cedar forests, remote beaches, and a true off‑the‑grid experience.
- Kythira: With waterfalls, Venetian castles, and mythic landscapes, Kythira bridges Peloponnesian road trips with ferries to Crete.

Agistri – Pine forests and an easy Athens escape
Agistri is one of the closest islands to Athens, just a short ferry ride from Piraeus, yet it feels worlds away from the city. Covered in pine forests and ringed by clear waters, the island is popular for swimming, cycling, and hiking, with a laid‑back atmosphere that makes it ideal for a quick getaway. The main villages of Skala and Megalochori offer tavernas, small beaches, and a relaxed pace, while quieter coves can be reached by bike or on foot. With its combination of accessibility and natural beauty, Agistri is a favorite for Athenians seeking a weekend retreat and for travelers looking to add a simple, authentic island to their itinerary.

Antikythira – Birdwatchers and ancient shipwrecks
Antikythira is one of Greece’s smallest inhabited islands, perched between Kythira and Crete. With only a few dozen permanent residents, it’s a place where time feels suspended. The island is best known for the discovery of the Antikythera mechanism, an ancient device often called the world’s first computer, found in a shipwreck off its coast. Today, Antikythira attracts birdwatchers who come to see migratory species resting on the island during their journeys between Europe and Africa. The main settlement, Potamos, has a handful of houses and a small harbor, while the rest of the island is rugged and windswept. Accommodation is minimal, and most visitors arrive on day trips or short stays from Kythira or Crete. For those who make the effort, Antikythira offers a rare glimpse of Greek island life at its most remote and unspoiled, with history and nature intertwined.
Elafonisos – Simos Beach and Peloponnesian charm
Elafonisos is a small island just off the southern Peloponnese, famous for Simos Beach, often ranked among the best in Greece. The beach is a double‑sided stretch of fine sand and turquoise water, ideal for swimming and camping. Despite its growing reputation, Elafonisos remains low‑key, with a single village where tavernas serve fresh seafood and ferries shuttle back and forth to the mainland in just ten minutes. The island is popular with Greek families in summer, but outside peak season it retains a relaxed, almost sleepy atmosphere. Accommodation is limited to small hotels and rooms to rent, which helps preserve its charm. Elafonisos is easy to combine with a Peloponnese road trip, especially if you’re exploring Monemvasia or heading toward Mani. For travelers who want a spectacular beach experience without the crowds of the Cyclades, Elafonisos is a perfect detour.

Gavdos – Europe’s southernmost point
Gavdos lies south of Crete and holds the title of Europe’s southernmost inhabited island. It’s a place that feels like the edge of the map, with cedar forests, sandy beaches, and a population that swells only in summer. The island’s most famous spot is Tripiti, marked by a giant chair sculpture overlooking the Libyan Sea, symbolizing its “end of Europe” status. Gavdos has long attracted free campers and travelers seeking an alternative lifestyle, but in recent years small guesthouses and tavernas have made it more accessible. Ferries connect it to Crete, though schedules are weather‑dependent, adding to the sense of remoteness. Life here moves slowly: mornings on the beach, afternoons under tamarisk trees, evenings with fresh fish and raki. For travelers who want to disconnect completely, Gavdos offers a rare chance to experience Greece at its most elemental and untamed.

Kythira – Myth, waterfalls, and Peloponnesian detour
Kythira sits at the southern tip of the Peloponnese, officially part of the Ionian Islands but geographically closer to Crete. It’s long been associated with the myth of Aphrodite’s birth, and the island still carries a sense of timeless beauty. Villages are scattered across hillsides, Venetian castles guard the coastline, and waterfalls like those at Mylopotamos add a surprising touch of greenery. Kythira is best explored by car, as public transport is limited, and its beaches range from sandy stretches to hidden coves reached by dirt tracks. The island has a slower rhythm than the busier Ionian hubs, with family‑run tavernas and small guesthouses forming the backbone of tourism. Ferries connect Kythira to the Peloponnese and Crete, making it a natural add‑on to a mainland road trip. For travelers seeking a mix of myth, history, and quiet landscapes, Kythira is a rewarding island.

Trizonia – A Corinthian Gulf secret
Trizonia is the only inhabited island in the Corinthian Gulf, a small green dot between mainland Greece and the Peloponnese. With no cars and only a few hundred residents, it feels like a step back in time. The island’s harbor is lined with tavernas serving fresh fish, and yachts occasionally stop here on their way through the Gulf. Beyond the port, you’ll find quiet paths, small beaches, and views across to the mainland mountains. Accommodation is limited, but that’s part of the appeal: Trizonia is not a place for busy itineraries, but for slowing down. Access is easy — a short boat ride from the village of Glyfada near Nafpaktos — yet few travelers make the detour. For those exploring central Greece or the northern Peloponnese, Trizonia offers a rare chance to experience authentic island life without straying far from the mainland.
Practical Tips
Getting there & island hopping
These islands are scattered, so planning is key. Some natural clusters help:
- Close to Athens: Agistri – just a 1-hour ferry from Piraeus, making it perfect for day trips or short stays.
- Peloponnese & Crete edge: Elafonisos and Kythira – Elafonisos is reachable via short ferries from the Peloponnese (Neapoli/Lakonia), while Kythira connects to Crete and the Peloponnese by ferry or small plane.
- Remote & southernmost: Gavdos and Antikythira – these require careful planning: Gavdos is accessed via Chora or Paleochora in Crete, and Antikythira only has occasional sailings from Kythira or Crete.
- Corinthian Gulf, accessible from Central Greece: Trizonia is a short boat ride from Glyfada near Nafpaktos; there are no cars, so everything is walkable.

Even among Greece’s most remote islands, a few have small airports that make access surprisingly easy. They’re included in my full guide to quiet Greek islands with airports.
How long to stay
Remote islands reward different rhythms of travel. Elafonisos is compact enough for 2–3 days, perfect to enjoy its beaches before moving on. Larger and wilder islands like Kythira call for 4–6 days, giving you time to hike waterfalls and explore villages without rushing. The more isolated the island, the more worthwhile it becomes to stick around, as limited transport and slower pace make extended stays part of the experience.
Best time to visit remote Greek islands
- May–June & September–October – warm seas, mild weather, and fewer crowds.
- July–August – main islands like Agistri fill up, but Elafonisos and Kythira remain relatively quiet.
- Winter – very off-season; some ferries may not operate, but you’ll have true solitude.
Getting around
- Larger islands: Kythira and Elafonisos benefit from car or scooter rentals to reach waterfalls, beaches, and villages.
- Tiny islands: Agistri, Trizonia, Gavdos, and Antikythira are easily walkable. A bicycle or scooter rental can help explore the few roads efficiently.
Connectivity and Internet on Remote Greek Islands
Signal can be unpredictable on the smaller, far‑flung islands beyond the main groups. Long dirt roads, low population, and limited infrastructure mean you’ll hit stretches where mobile data fades out completely. These places feel wild and disconnected in the best way, but it helps to know which networks hold up when coverage gets thin.
My guide to the best eSIM for Greece explains the options that perform most reliably on remote islands like these.
Accommodation
Expect family-run guesthouses, small hotels, and seaside tavernas serving fresh fish and local specialties. Booking ahead is smart, especially in peak summer, because accommodation is limited.
Final Thoughts
These outlier islands expand the definition of Greek island travel. They’re not about ticking off famous names, but about finding the edges where myth, solitude, and local rhythms still shape daily life. Some are perfect for short add‑ons to an Athens itinerary (Agistri) or mainland Greece itinerary (Trizonia), while others reward slow travel (Gavdos, Kythira). Together, they reveal a quieter, more authentic Greece for those willing to wander off the main routes.
