Spalathronisi Island (€10,000,000)
- Location: Toroneos Gulf, Sithonia
- Size: 26 acres, 10.4 hectares
- Description: Approx. 500 m from shore, 8 km NW of Toroni.
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Around 500 metres off the Sithonia coast of Halkidiki, between the Porto Carras resort area and Porto Koufos, Spalathronisi is a rare whole private island in northern Greece. The island sits in the clear waters of the Toroneos Gulf, close to the mainland yet still offering a distinct private-island setting.
The island is currently undeveloped, but its strongest reported feature is planning potential. The listing describes approved tourist-development capacity of around 8,000 m², including guest and auxiliary facilities, which would make it highly unusual in a market where island development rights are often difficult and slow to secure.
Its location is also a major advantage. Sithonia is one of Halkidiki’s most attractive coastal areas, known for pine-covered hills, turquoise bays and summer resort demand. Spalathronisi benefits from this established destination while remaining separated from the mainland by a short boat crossing.
For a developer or private buyer, Spalathronisi offers a combination of access, location and reported planning progress that is rarely available on a Greek island. All permits, planning terms and development rights should still be verified before presenting it as build-ready.
Makri Island (€8,000,000)
- Location: Ithaki, Kefalonia, Ionian Islands, Ionian Sea
- Size: ~243 acres, ~98 hectares
- Description: 4km from shore, 53km northeast of Kefalonia Airport, 226km west of Athens
- Ownership: Leasehold (100 years)
- Development: Non-developed
- Map: See on Google Earth
Makri is a private island in the Ionian Sea, 30 kilometres east of Kefalonia and 60 kilometres northwest of Patras, Greece’s third-largest city. Corfu and Zakynthos are also two of the more well-known travel hubs within the surrounding area – both islands offer an array of recreation and leisure opportunities.
The Ionian Islands are distinguished for their meandering coastlines, sandy beaches, marine-rich waters, and verdant greenery. Makri, though one of the coast’s more conspicuous islands, is an embodiment of these traits.
The 243-acre property delivers over seven kilometres of coastline and forested peaks. However, the island’s forested state puts its potential for development into severe question. Makri’s owner once embarked on a project to parcel any buildable land on the island and construct houses to rent or sell. However, the plan was never fulfilled, and the more recent forestry assessments have created new obstacles regarding expansion.
Makri is an island with an alluring foundation, but more clarity is needed for buyers set on development.
Kardiotissa Island (€5,000,000)
- Location: Sikinos, Cyclades
- Size: 133 hectares, 329 acres
- Description: Approx 2.5km from shore, 5km NE of Karavostasis
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
In the open Aegean between the quiet islands of Sikinos and Folegandros, Kardiotissa is one of the larger uninhabited private islands in the Cyclades. Spanning approximately 133 hectares, or 329 acres, it offers rare scale in one of Greece’s most sought-after island regions.
The island is undeveloped, with no roads, buildings or permanent residents. Its character is raw and natural, shaped by rugged Cycladic terrain, open sea views and clear water on every side. For a buyer who values space, privacy and untouched landscape, Kardiotissa offers a type of island holding that is increasingly difficult to find.
Its position adds to the appeal. Secluded, but within sailing reach of Folegandros, Ios and Santorini, the island sits in the heart of the southern Cyclades while still feeling removed from the busier routes of the Aegean.
Kardiotissa could suit a buyer looking for a private nature reserve, a long-term island holding or a carefully planned estate, subject to all Greek planning and environmental approvals. With its size, location and untouched condition, it stands out as a serious whole-island opportunity in the Cyclades.
Kouneli Island (€4,000,000)
- Location: Ithaki, Kefalonia, Ionian Islands, Ionian Sea
- Size: 23 acres, ~9 hectares
- Description: 3km from shore, 54km northeast of Kefalonia Airport
- Ownership: Information upon request
- Development: Non-developed
- Map: See on Google Earth
Kouneli is a private island amongst the Ionian group. Its closest neighbour, Makri, is also for sale on the Greek real estate market.
The island comprises 23 acres of sloped and level land, lengths of rocky shorelines, and an abundance of interior vegetation. Regardless of its flora coverage, the island has been cleared of all forestry restrictions.
There are indications that some parcels of land on Kouneli can be developed, though further inquiry would be necessary. At present, the island offers no serviceable structures and there are no amenities. A prospective buyer would also likely have an interest in building a dock or small harbour to facilitate passage on and off the property.
A promising island on the more affordable end of the market.
Nisida Panteleimona (€3,500,000)
- Location: Inousses, Chios Strait
- Size: 9 acres, ~3.6 hectares
- Description: 100m from shore, 20km NE of Chios Airport Omiros, ~220km NE of Athens
- Ownership: Freehold
- Development: Developed, with further potential
- Map: See on Google Earth
Archetypal island beauty, proximity to community hubs and tourist interests, and the potential for development – Panteleimona is a special property set to garner significant interest on the Greek real estate market.
Sheltered by the island of Inousses (often also referred to as Oinousses) in the Chino Strait, Nisida Panteleimona delivers an ideal balance of connectivity and calm. The islands are separated by just over 250 metres of water, making transit between the two as simple as a short boat ride. Due to the proximity of Inousses’ main settlement (of the same name), prospective residents will have near-direct access to amenities and services.
In its current state, the island features three small churches, each with its own unique history. An electrical generator serves the churches, and there is also a well for drinking water.
Looking forward, Panteleimona has development potential for up to 200 square metres. This declaration includes clearance from the forestry department and complete title deeds supported by all necessary documentation.
Whether for a private residence or a small rental property, Nisida Panteleimona is primed for immediate development. Such combinations of natural assets, connectivity, and complete documentation are rare.
Xeronisi Island (€3,000,000)
- Location: Aegean Islands, Kavala
- Size: 36 acres, ~14.5 hectares
- Description: 1km from shore, ~23km east of Kavala Airport
- Ownership: Information upon request
- Development: Development potential
- Map: See on Google Earth
This well-connected private island is located just one kilometre from shore, 8.5 kilometres from the seaport city of Kavala, and approximately 120 kilometres east of Thessaloniki. Both cities offer access to international airports, though Thessaloniki (Greece’s second-largest city) transits more flights.
The proximity of both major settlements also guarantees access to essential services and desirable amenities – a valuable asset for those in the market for a private island.
Of the island’s total area, three hectares are designated as forestland, thus strictly prohibiting construction. However, the rest of the island’s approximately 11.5 hectares can be built upon. Much of the island’s 2.5-kilometre coastline is inaccessible, though some areas would suit development. There are also a handful of small, shallow beaches on the island’s eastern and northern sides. The interior is dominated by indigenous vegetation – wild olive trees, fruit trees, and other shrubs.
Panoramic sea views, convenient land access, and recognised build potential – this is an undeveloped island worth noting.
Strongyli of Antiparos (€3,000,000)
- Location: Cyclades, S Aegean
- Size: 297 acres, 120 hectares
- Description: Approx. 5 km from shore, 14 km SW of Paros Airport.
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
In the heart of the Cyclades, within sight of Antiparos and Paros, Strongyli of Antiparos is a rare whole-island opportunity in one of the most desirable parts of the Aegean. Spanning approximately 120 hectares, or 297 acres, it is among the larger private islands for sale in Greece and offers remarkable scale for its price point.
The island is currently undeveloped, with no roads, buildings or permanent residents. What it offers instead is raw Cycladic landscape, open sea views and the clear blue water that has made this part of Greece internationally known. It is a true blank canvas, best suited to a buyer with patience, vision and the ability to navigate the Greek planning process.
Development may be possible, but it should be approached carefully. The opportunity appears to depend on an approved business plan rather than a simple off-the-shelf building permit, making it more suitable for a considered eco-resort, hospitality concept or large private estate than a quick residential build.
For a developer or long-term private buyer, Strongyli offers a rare chance to shape an entire island close to Antiparos and Paros while still keeping a strong sense of separation and privacy. With its size, location and undeveloped character, it stands out as a serious Aegean island development opportunity rather than a ready-made retreat.
Stroggilo Island (€2,500,000)
- Location: Patmos, Kalymnos, Dodecanese, Aegean Sea
- Size: ~54 acres, ~22 hectares
- Description: 160m from Marathi Island, 22km south of Aérodrome de Leros
- Ownership: Freehold
- Development: Non-developed
- Map: See on Google Earth
Spanning 54 acres within the blue waters of the Aegean Sea, Stroggilo Island presents itself as an ideal sanctuary for sailors and island hoppers.
Stroggilo, or Strogylo as it is locally named, hosts generous anchorage alongside three natural beaches. These features foster curiosity as to the island’s development potential. While an old house and a well with groundwater currently sit in ruin on the property, future efforts to redevelop or expand would be subject to planning permission and approval from the relevant authorities. As such, diligent inquiries into Strogglio’s affairs would be recommended.
Notwithstanding questions of Strogglio’s commercial availability, the property is attractively proximate to other recreational landmarks. The serene beach destination of Marathi is a short boat journey away and offers access to a selection of tavernas.
Athanasios Island (€2,200,000)
- Location: Itea, Delphi, Fokida, Corinthian Gulf
- Size: ~2.6 acres, ~1.1 hectares
- Description: 1km from shore, 92km northeast of Araxos Airport, 124km west of Athens
- Ownership: Freehold
- Development: Development potential
- Map: See on Google Earth
St. Athanasios is the smallest island in the Greek market. But, its manageable size, flat land, and picturesque location provide ideal conditions for private residential development.
The island lies just one kilometre from the shore and can be reached by boat from the nearby coastal town of Itea. Olive and pine trees inundate St. Athanasios’ interior, while a small sandy beach marks the northwestern coast.
Though, perhaps the island’s greatest asset is its unrestricted freehold title. The property also boasts an indispensable ensemble of supporting documents from all relevant public authorities. Lastly, for investors with an eye towards development, St. Athanasios is free of Natura 2000 area restrictions.
As such, there is scope for the construction of a private residence.
St. Athanasios’ profile and potential surpasses its modest size.
Skyropoula (Price Upon Request)
- Location: Western Saronic, Gulf of Korfos
- Size: ~1,038 acres, ~420 hectares
- Description: Approx. 6 km from shore, 17 km SW of Skyros Airport.
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Set in the Aegean between Skyros and Evia, around an hour from Athens, Skyropoula is a private island of exceptional scale. Spanning approximately 420 hectares, or about 1,038 acres, it is one of the largest Greek private islands to appear on the market and offers a level of space and seclusion rarely available in this part of the Mediterranean.
The island remains undeveloped, with three pine and olive covered hills rolling down toward a long and varied coastline. Two natural harbours provide sheltered anchorage, while the island’s historic stone church, dating back to 1726, adds a sense of permanence and character to an otherwise untouched landscape.
One of Skyropoula’s strongest reported advantages is its title position. The listing describes the ownership as clean, complete and recognised by both the Greek State and the European Union, which is an important point in a market where island ownership and development rights often require careful legal verification.
For a buyer thinking long term, Skyropoula offers the scale to create a major private estate, a discreet eco-resort or a generational island holding kept largely wild. With its size, location near Skyros, natural harbours and reported title clarity, it stands out as a serious trophy island opportunity in the Aegean.
St. John’s Island (Price Upon Request)
- Location: Western Saronic, Gulf of Korfos
- Size: ~750 acres, ~303 hectares
- Description: Approx. 7 km from shore, 57 km W of Athens International Airport.
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
At the northern end of the Diapori island group, in the sheltered western Saronic Gulf off Korfos, Agios Ioannis, also known as St. John’s, is the largest of a small private cluster of islets within easy reach of Athens. Open, sunny and undeveloped, it offers a rare combination of seclusion, clear water and strong access to the Greek capital.
The island is a true blank canvas, with gentle open ground, an accessible shoreline and views across the surrounding islets toward the Peloponnese. Freehold and untouched, it could suit a private estate or a quiet, low-density retreat designed around the calm character of the Saronic Gulf.
Its position is the main strength. Agios Ioannis offers a private-island setting within a manageable boat ride of Athens, in sheltered waters known for sailing and coastal escapes. For a buyer seeking privacy without giving up access, it is a rare foothold in one of Greece’s most accessible island regions.
Tragonisi (Price Upon Request)
- Location: Western Saronic, Gulf of Korfos
- Size: ~90 acres, ~36 hectares
- Description: Approx. 5km from shore, 60km W of Athens International Airport
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
In the calm western reaches of the Saronic Gulf, close to the fishing village of Korfos and around 45 minutes by boat from Athens, Tragonisi is one of the private islets within the Diapori group. Sunlit, sheltered and intimate in scale, it offers a rare private-island setting within easy reach of the Greek capital.
The island is undeveloped, with open sloping ground leading down toward a sandy beach, a valuable feature on an islet of this size. Its freehold status, accessible shoreline and simple natural terrain make it a strong blank-canvas opportunity for a discreet private retreat or low-density island escape.
Tragonisi’s strength lies in its setting. The surrounding Saronic waters are sheltered and clear, with views across the neighbouring Diapori islets and toward the Peloponnese. For buyers seeking the romance of a Greek private island without deep remoteness, Tragonisi offers privacy, manageable access and a quiet position in one of Greece’s most approachable island regions.
Santorini Island (Price Upon Request)
- Location: Cyclades, S Aegean
- Size: ~34 acres / ~14 hectares
- Description: Approx. 2km from shore, 11km W of Santorini Airport
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Set inside the Santorini caldera, Aspronisi is one of the most visually striking islets in the Cyclades. Located just off Santorini’s famous volcanic coastline, it offers a rare position within one of Greece’s most recognisable island landscapes, with open views across the caldera and toward the sunset-facing side of the Aegean.
The islet is described as undeveloped, with natural shoreline access, two beaches and volcanic terrain shaped by the same geological story as Santorini itself. Its appeal is not large-scale infrastructure or ready-made estate living, but the unusual chance to hold a private island position in a setting known worldwide.
However, this listing should be treated with caution. The available information appears limited, and the island’s location inside the Santorini caldera means any development potential would need careful legal, planning and environmental verification. It should not be presented as a simple resort or build-ready opportunity without stronger confirmation.
For the right buyer, Aspronisi may be best understood as a rare natural holding rather than a conventional development island. Its value lies in its location, views and symbolic position within the Santorini landscape, but ownership, sale status and permitted use should all be confirmed before it is published as an active opportunity.
Vouvalos Island (Price Upon Request)
- Location: Preveza, Epirus, Ambracian Gulf
- Size: ~32 acres, ~13 hectares
- Description: 4km from shore, 270km northwest of Athens
- Ownership: Freehold
- Development: Non-developed
- Map: See on Google Earth
Vouvalos Island sits within the Ambracian Gulf – both the largest enclosed gulf in Greece and an area designated as a national park due to its ecological significance. The inlet is also a region less travelled than most, but that fact does not diminish the resident beauty. Rather, it shows the area to be one of Greece’s hidden gems.
Vouvalos itself is an island of particular charm. Its unusual shape provides several natural harbours and beaches, ideal spaces for recreation and leisure. Meanwhile, much of the property’s interior is marked by olive groves and pine trees. A lagoon also sits at the centre of the island.
Information regarding the island’s development potential requires further inquiry.
