- Location: Loop Head Clare, Clare
- Size: 60 acres
- Description: 20km SW of Kilkee, 67km SW of Shannon Airport
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth

Built to exacting standards, this home blends striking architecture with classical influences. Ornate decorative ceilings, a stone staircase with brass-coated balustrades, and exquisite Bossi chimneypieces merge seamlessly with modern design. A helipad, sea, and road access ensure convenience.
Nearby amenities include Kilbaha Bay Harbour, Carrigaholt village, Kilkee, Kilrush, and access to Kerry.

The lower level features a pool room, ‘Champagne Room,’ and changing rooms. The master bedroom suite, two more bedroom suites, and a guest bedroom suite complete the picture, with a lovely courtyard, integral garaging, laundry, and back kitchen.
2. Whiddy Island Estate (incl. Rabbit Island) (€4,000,000)
- Location: Bantry Bay, County Cork
- Size: 226 acres
- Description: 3 km W of Bantry, 85 km SW of Cork city
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Set at the head of Bantry Bay, Whiddy Island Estate is less a single remote island than a substantial coastal estate with its own private island included. Assembled over several decades, the holding extends to approximately 226 acres of rolling coastal farmland and includes Rabbit Island, a separate freehold island just offshore.
The estate is unusually developed for an island opportunity. It includes multiple residential and commercial buildings, reportedly as many as ten houses, several cottages, a seafront main residence with its own slipway, and the Bank House Restaurant & Bar, which operates as a commercial premises with an apartment above.
Whiddy Island also carries notable historical depth. The land includes sites linked to early monastic settlement and a holy well at Kilmore, while The Battery, a gun fort built in 1804, reflects the island’s strategic role in guarding Bantry Bay during the Napoleonic period. In 1918, Whiddy also hosted a US Navy seaplane station, adding another layer to its maritime history.
Unlike a castaway-style island, Whiddy is gently inhabited and connected to Bantry by a short ferry crossing of around ten minutes. This makes the estate more suitable as a hospitality business, rental portfolio, family compound or long-term West Cork investment than a purely private wilderness retreat. The property is available as a whole or in separate lots.
3. Cameron Island (€950,000)
- Location: Lough Derg, County Tipperary
- Size: 100 acres
- Description: 12 km NW of Nenagh, 40 km NE of Limerick city
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Set on Lough Derg, Cameron Island is a rare freehold lake island estate of approximately 100 acres, with The Lake House standing as its only residence. Reached by boat in around five minutes from the mainland quay, the island offers privacy, water access and wide views across one of Ireland’s great inland lakes.
The single-storey house was comprehensively refurbished in 2005 and includes a hall, study, bright kitchen-dining-living space and three bedrooms. Its own stone harbour provides direct island access, making the property practical as a private retreat while still keeping the feeling of full separation from the mainland.
The gardens around the house are a major part of the appeal. Around 1.5 acres have been planted as an arboretum, with specimen trees including Judas tree, copper beech, red oak, Japanese maples, ginkgo and pines. A Victorian croquet lawn, Zen garden, lily pond with fountain and small walled orchard add a highly cultivated character to the lakeside setting.
Beyond the gardens, native woodland covers much of the remaining island, helping preserve its privacy and natural atmosphere. Located near the boating and angling areas of Coolbawn, Terryglass and Dromineer, Cameron Island offers a turnkey island home on Lough Derg, suited to buyers seeking a private family retreat, nature-rich estate or long-term Irish lake holding.
4. Shore Island (€900,000)
- Location: Near Cloonakilla and Kildysart, County Clare, North Atlantic Ocean
- Size: 30 acres
- Description: 300m from shore, 2.3km from Ballynacally Pier, Western Ireland
- Ownership: Freehold
- Development: Non-developed
- Map: See on Google Earth
What currently exists as agricultural land also presents an intriguing opportunity for development – pending the relevant bureaucratic processes.
Shore Island, a 30-acre island within the Shannon Estuary, currently finds purpose as year-round grazing land for cattle. But several ruins that remain on the island have the potential to help planning permission applications for new, inhabitable residences. There is already a pipe supplying fresh water to the island.
Deep tidal waters surround the island, making Shore Island only accessible by boat.
Though the vicinity to various towns and transport links eases any concerns about accessibility and convenience – once on land, it takes 40 minutes by car to reach Shannon Airport.
5. Ardoilean (€750,000)
- Location: West coast of Barnanrusheen, south of Inishbofin, North Atlantic Ocean
- Size: 79 acres
- Description: 4km from shore, 5.5km from Barnanrusheen, Western Ireland
- Ownership: Freehold
- Development: Non-developed (ruins)
- Map: See on Google Earth
Ardoilean Island is a unique investment opportunity. The property, also known as High Island, is an expanse steeped in history, with archaeological artefacts inundating the ~79-acre plot. Foremost, church remnants on the island correlate with early Iron Age settlements. There is also the foundation of a monastery on Ardoilean’s southwestern edge that dates back to the seventh century. Other examples of historical relics are the remains of an old water mill, a granite globe, and a long-disused copper mine shaft.
Beyond its historical reputation, Ardoilean endures as an island of immense natural value – serving as a haven for a vast array of birdlife. Fulmars, petrels, shearwaters, gulls, and oyster catchers live on the island. Barnacle geese also visit during the winter.
There is a more modern building near Ardoilean’s southern landing area. A septic tank also suggests future building potential, though any construction would be subject to the necessary planning constraints.
Due to its historical value, the resident monastery is not part of the sale. Regardless, the opportunity to own the surrounding island – one of such historical significance – is nothing short of rare.
6. Long Island (€550,000)
- Location: Lower Lough Erne, County Fermanagh
- Size: 12 acres
- Description: 5 km N of Enniskillen, 140 km SW of Belfast
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Set within the broad waters of Lower Lough Erne, Long Island is a genuine private lake island of approximately 12 wooded acres in the Fermanagh Lakelands. With no bridge, no causeway and no immediate neighbours, it offers a rare level of privacy while remaining only a short boat journey from Enniskillen, Killadeas Marina and Lough Erne Yacht Club.
At the heart of the island is an off-grid residence with two to three bedrooms, supported by its own generator for light, heat and everyday use. A private jetty and marina provide direct boat access, making the island practical as either a seasonal escape or a full-time retreat for buyers comfortable with water-only access.
The current owners have lived on and improved the island since 1978, giving the property a lived-in character rather than the feel of a simple holiday cabin. A Certificate of Lawfulness reportedly confirms its residential use, with possible scope for further development subject to planning consent.
Mostly covered in mature woodland and threaded with shoreline paths, Long Island combines privacy, natural beauty and established residential use in one of Ireland’s most scenic lake districts. It is best suited to a buyer looking for a secluded island home, family retreat or long-term lakeland holding with access by private boat.
7. Inis Saimer (€299,000)
- Location: South of Abbey, North of Milltown, River Erne
- Size: 1 acres
- Description: 100m from shore, 500m from Ballyshannon, Northern Ireland
- Ownership: Freehold
- Development: Developed
- Map: See on Google Earth
Inis Saimer is a residential island on the River Erne – an area noted for its serene atmosphere and high quality of life. The town of Ballyshannon is within eyeshot of the island and offers convenient access to shops and restaurants.
Foremost, purchasing the plot includes an established residence – a spacious home boasting open-plan living spaces and national grid connections. Three bedrooms also provide generous living capacity.
The island benefits from a private jetty – The Mall Pier (Ballyshannon’s quay) is just 100 metres upriver. The Erne Estuary, within which the property resides, is prime sea trout angling territory.
Inis Saimer is an investment ready for immediate enjoyment.
8. Mason Island (€120,000)
- Location: Carna, County Galway
- Size: 2 acres
- Description: 6.5 km W of Carna, 80 km WNW of Galway city
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
The last families left Mason Island in 1957, and the Atlantic has kept it quiet ever since. Known in Irish as Oileán Máisean, the island lies just off Mace Pier in the Carna Gaeltacht of south Connemara, close enough to the mainland for a short crossing, with the Twelve Bens visible on the horizon and white sand along parts of its shore.
For sale is a freehold parcel of approximately 2 acres, including two stone ruins that were once dwelling houses, together with the island’s own pier. The parcel sits close to the landing point, making it one of the more accessible opportunities on the island.
Because the ruins were formerly homes, the agent suggests that reinstatement or rebuilding may be possible, subject to planning consent. This gives the property potential as an off-grid island retreat in one of Ireland’s most distinctive coastal regions, although any development should be carefully verified with the local planning authority.
Mason Island has a deep human history. At its height, it supported more than a hundred residents, while early Christian relics suggest much older settlement. Today, it is known for its quiet beauty, Gaeltacht setting, walking routes and the traditional Galway hooker and currach sailing culture that still shapes this part of the Connemara coast.
9. Inishdaweel Island (Price Upon Request)
- Location: Clew Bay, County Mayo
- Size: 17.2 acres
- Description: 6 km SW of Newport, 12 km NW of Westport
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Set within the sheltered inner waters of Clew Bay, Inishdaweel Island is a low, green freehold island of approximately 17.2 acres. Clew Bay is one of Ireland’s most distinctive coastal landscapes, known for its many drumlin islands, with Croagh Patrick rising to the south and the Nephin Beg range to the north.
The island itself is simple and undeveloped. There is no house, ruin or built structure, only open grazing land that has long supported cattle and sheep. Its appeal lies in its privacy, natural setting and position within the calm waters of the bay, rather than in ready-made buildings or immediate development potential.
Inishdaweel also sits within a wider landscape rich in Irish history and folklore. Clew Bay is strongly associated with Grace O’Malley, the famous pirate queen, whose castles still stand in the region. Dorinish Island, once owned by John Lennon, lies further out in the bay, adding another layer of cultural interest to the surrounding waters.
Because Inishdaweel is within the Clew Bay Complex Special Area of Conservation, it should be viewed primarily as an amenity, conservation or lifestyle holding rather than a straightforward building plot. For the right buyer, it offers a private uninhabited island with grazing, birdlife and peaceful anchorage in one of western Ireland’s most beautiful bays.
10. Inishskehan Island (Price Upon Request)
- Location: Clew Bay, County Mayo
- Size: 17.2 acres
- Description: 6 km SW of Newport, 12 km NW of Westport
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Freehold islands rarely come up on Lough Corrib, and almost never at this scale. Inishskehan, also known as Inis Sceithín, meaning “island of the little whitethorn,” is an approximately 8-acre island on the sheltered eastern side of Ireland’s largest lake, west of Headford and within a short boat trip of the piers at Greenfields and Annaghkeen.
The island is low, natural and largely untouched. Lough Corrib is known for its wild brown trout and salmon fishing, protected wetland character and famously island-filled waters, with more than 1,300 islands often associated with the lake. To own one of them outright is an unusual opportunity.
Inishskehan is close to a blank canvas. The land is unzoned, and its only structure is a traditional dry-stone sheep pen built years ago by the current owner’s father, giving the island a small but meaningful piece of local heritage within an otherwise undeveloped setting.
For the right buyer, the island could suit a private retreat, conservation-minded holding or long-term land investment, with any future building subject to normal Irish planning consent. Galway city, Cong and the gateways to Connemara all remain within practical reach from the surrounding shoreline.
11. Inishbarna Island (Price Upon Request)
- Location: Killary Harbour, County Galway
- Size: 22 acres
- Description: 14 km W of Leenane, 75 km NW of Galway city
- Ownership: Freehold
- Development: Undeveloped
- Map: See on Google Earth
Set at the mouth of Killary Harbour, Ireland’s only true fjord, Inishbarna is a wild freehold island of approximately 22 acres. Known in Irish as Inis Bearna, meaning “island of the gap,” it rises sharply for its size and looks out across the water toward Mweelrea and the Connemara mountains.
The island has a striking cultural and historical character. In 1948, philosopher Ludwig Wittgenstein, while working nearby at Rosroe, reportedly became fascinated by Inishbarna and considered building a cottage there, before being warned that the Atlantic weather would make such a structure difficult to keep standing. A century earlier, the poet Seán Mac Conmara lived on the island and wrote of British warships passing below.
Today, Inishbarna remains undeveloped and exposed in the best Connemara sense. A white navigation beacon still stands on the island, guiding vessels toward Leenane, while 19th-century ruins of a bothy and cattle enclosure add traces of past use. There is no habitable dwelling, and the island should be understood as a wild holding rather than a ready-made retreat.
For the right buyer, Inishbarna could suit conservation ownership, a summer camp, a private wilderness escape or a long-term landholding in one of the west of Ireland’s most dramatic coastal landscapes. Access is by boat from Leenane or Rosroe, with mussel farms, sea-angling and some of Connemara’s finest walking country nearby.
12. Middle Calf Island (Price Upon Request)
- Location: Near Schull and Baltimore, North Atlantic Ocean
- Size: 64 acres
- Description: 5km from Cunnamore Pier, 3.3km from Cape Clear Island, Southwest Ireland
- Ownership: Freehold
- Development: Non-developed (ruins)
- Map: See on Google Earth
Nestled between its sibling islands – West Calf and East Calf – Middle Calf Island offers a prime location in the middle of County Cork’s Roaring Water Bay.
Of similar size to its western neighbour, which is also listed on the private island market, Middle Calf has a history of human habitation and agricultural usage. Once home to numerous families and a school, the island now only supports a herd of grazing Kerry Bog ponies – though numerous ruins endure as reminders of the land’s heritage.
The paperwork did exist to support the reconstruction of dwellings on the island, but those applications have since expired – new investors would be encouraged to renew any development paperwork.
Of the island’s natural bounty: several small lakes proliferate the ~64-acre landscape, as well as several beaches.
