11 Islands for Sale in Chile

Latest listing added: August, 2026

1. Isla Huelmo ($9,200,000)

---

Link to original listing

• Location: Reloncaví estuary, near Puerto Montt, Los Lagos
• Size: ~168 acres, 68 hectares
• Description: 22km SSW of Puerto Montt, Approx 59km NW of Hornopirén
• Ownership: Freehold
• Development: Developed
• See on Google Earth

Twenty-two kilometres from Puerto Montt, the airport city that opens all of Chilean Patagonia, Isla Huelmo offers sixty-eight hectares of private island within reach of an international gateway.

That combination is what makes it unusual. Most Patagonian islands demand a flight, a second flight and a boat. Huelmo sits in the Reloncaví estuary an easy run from a city with daily connections to Santiago, along with hospitals, supply and services.

The island is already under development. A main house is being built, with a secondary house, a caretaker’s residence and a dock in place, the hardest and most expensive part of any island project already solved.

Sixty-eight hectares leaves room to complete the scheme with genuine privacy, or to extend it. For a buyer who wants Patagonia without the logistics that usually come with it, Huelmo may be the most practically accessible large private island in southern Chile.

2. Isla Guardiamarina Zañartu and Islotes San Andrés ($7,000,000)

---

Link to original listing

• Location: Commune of Cisnes, Provincia de Aysén
• Size: ~951.4 acres, 385 hectares
• Description: 37km NW of Puerto Cisnes, Approx 143km NW of Coyhaique
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

A named island and its attendant islets, offered together: Isla Guardiamarina Zañartu and the Islotes San Andrés run to 385 hectares in the Cisnes commune of Aysén.

Buying an island with its satellites in one transaction changes what the holding can be. The main island carries the development; the islets supply separation, anchorage and an outlook no neighbour can alter. In an archipelago as crowded with small landforms as the Chonos, that control is worth a great deal.

Aysén is Chile’s emptiest region, a labyrinth of fjords, channels and forested islands with a population density closer to Greenland’s than to anywhere else in South America. International arrivals come through Balmaceda Airport, with onward connections into the channel network.

For a buyer wanting scale, seclusion and a defensible boundary in the least developed corner of Patagonia, this is a rare configuration to find intact and in single ownership.

3. Isla Puduhuapi ($6,900,000)

---

Link to original listing

• Location: Chaitén, Provincia de Palena, Los Lagos
• Size: ~1,729.7 acres, 700 hectares
• Description: 8km WSW of Chaitén, Approx 20 min by boat from Chaitén
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Eight kilometres from Chaitén, Isla Puduhuapi is a seven-hundred-hectare island in the Palena fjords, close enough to town for a twenty-minute crossing, remote enough to sit entirely within its own horizon.

This stretch of coast carries particular weight in conservation circles. It borders the country Douglas Tompkins assembled into Pumalín, the private park later donated to Chile that became the template for large-scale conservation purchase in Patagonia. Puduhuapi lies in that same landscape of temperate rainforest, volcanic peaks and fjord.

Seven hundred hectares accommodates almost any brief, a private estate with real separation, a lodge, or a conservation holding with buildings kept deliberately minor against the scale of the land.

Access is by commercial flight to Puerto Montt, light aircraft to Chaitén’s airfield, then the short boat crossing.

4. Isla García ($4,200,000)

---

Link to original listing

• Location: Commune of Cisnes, Provincia de Aysén
• Size: ~10,378 acres, 4,200 hectares
• Description: 95km WNW of Puerto Cisnes, Approx 170km SSW of Chaitén
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Four thousand two hundred hectares that have never been developed, never been divided, and never left a single owner’s hands. Isla García is as close to untouched Patagonia as private ownership gets.

The island lies in the Cisnes commune of Aysén, surrounded by national parks and reserves, a position that makes it an ecological sanctuary by geography as much as by intent.

Ten thousand three hundred and seventy-eight acres of native Patagonian wilderness, entirely virgin. There is no infrastructure, no prior scheme to work around, no history of subdivision to unpick. For a conservation buyer, that clean title is worth as much as the land itself.

Access runs through Puerto Montt’s La Paloma aerodrome with daily flights operated by Pewen Servicios Aéreos. Aysén is the least populated and least developed stretch of Chile, the part travellers reach last and remember longest.

5. Tic Toc Islands ($3,500,000)

---

Link to original listing

• Location: Gulf of Corcovado, Chaitén, Los Lagos
• Size: ~1,324 acres, 536 hectares
• Description: Gulf of Corcovado off Chaitén; nearest airfield Chaitén, Puerto Montt onward
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Not one island but roughly forty. The Tic Toc Islands form a private archipelago of some 536 hectares in the Gulf of Corcovado, off Chaitén in Chilean Patagonia, a scattering of forested islands and islets held as a single legacy holding.

Archipelago ownership is the rarest thing in this market. Instead of a boundary and a neighbour, a buyer acquires an entire seascape: the channels between the islands, the anchorages, the sheltered water, and forty separate shorelines from which to choose a building site. 

The setting is extraordinary even by Patagonian standards. The Gulf of Corcovado is one of the most important blue whale feeding grounds on the planet, and the surrounding waters were given marine park protection in 2022 for exactly that reason.

Native forest covers the islands. Chaitén provides the nearest airfield and supply point, with Puerto Montt connecting onward. Offered through Sotheby’s International Realty.

6. Isla Diego Portales ($3,000,000)

---

Link to original listing

• Location: Provincia de Última Esperanza, Magallanes
• Size: ~36,999 acres, 14,973 hectares
• Description: 45km SW of Puerto Natales, Approx 33km by sea from Puerto Natales
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Fifteen thousand hectares. Isla Diego Portales is not an island in the sense the market usually means, it is a landscape, a continuous holding of cliffs and native forest in the Última Esperanza province of Magallanes, with direct maritime access from Puerto Natales.

At this size the conversation changes entirely. A holding of this scale in Chilean Patagonia belongs in the same category as the great conservation properties of the region, the estates that went on to become national parks, rather than anything resembling a private retreat.

The land is undeveloped native forest and cliff shoreline, fronting the fjord systems that run west toward the Pacific. Puerto Natales, the regional hub and gateway to Torres del Paine, supplies air links and port logistics.

For a conservation buyer, an institution, or a family thinking in generations rather than seasons, Diego Portales is one of the largest single island holdings ever brought to the open market in South America.

7. Lacao Island ($2,600,000)

---

Link to original listing

• Location: Province of Chiloé, Ancud Commune
• Size: 206 acres, ~83 hectares
• Description: 700m from shore, ~16km northeast of Ancud
• Ownership: Freehold
• Development: Non-Developed
• See on Google Earth

The undeveloped island of Lacao, located just 700 metres offshore in Caulin Bay, is recognised locally for its natural charm. The substantial property, which spans in excess of 200 acres, features a northern edge that rises into a 14-metre cliff – a vantage point that offers sweeping views towards the mainland coast. Lacao’s southern boundary, instead, slopes gradually to sea level, where a sand beach meets deep blue waters. Open pastures, dense thickets, and an area of wetland cover the land in between. 

Proximate to the cities of Ancud and Puerto Montt, Lacao Island has the potential for a variety of purposes – from habitat conservation to private sanctuary or commercial development.

8. Isla Manzano ($1,859,000)

---

Link to original listing

• Location: Caleta Manzano, Hualaihué commune, Los Lagos
• Size: ~35.1 acres, 14.2 hectares
• Description: 16km WSW of Hornopirén, Approx 65km SSE of Puerto Montt
• Ownership: Freehold
• Development: Developed
• See on Google Earth

Isla Manzano arrives finished. A main house and three cabins already stand on fourteen hectares of fjord island, which in Chilean Patagonia, where most island stock is raw forest and rock, is a genuine rarity.

The island lies off Caleta Manzano in the Hualaihué commune, sixteen kilometres from Hornopirén and sixty-five southeast of Puerto Montt. This is fjord country at the head of the Carretera Austral: sheltered water, dense native forest, mountains rising straight from the shoreline.

The existing buildings mean a buyer can use the island from the first season rather than committing to a construction programme in a region where every sheet of material arrives by boat. That logistical reality is precisely why developed Patagonian islands trade at a premium to their acreage.

For a family retreat, a small lodge, or a base for exploring the fjords, Manzano offers what most of its neighbours cannot: somewhere to sleep on the night you arrive.

9. Imalev Island ($1,500,000)

---

Link to original listing

• Location: Province of Chiloé, Castro Commune
• Size: 32 acres, ~13 hectares
• Description: 3km from shore, ~29km east of Chonchi
• Ownership: Freehold
• Development: Non-Developed
• See on Google Earth

Imalev Island is a 32-acre property within the Chiloé Archipelago – a collection of islands located between Chiloé Island and the Chilean mainland. As one of the smaller islands within the group, Imalev is well-sheltered on both flanks from the elements. 

The triangular property rises to a cliff on its south-southeastern edge – the 80-metre bluff features a lighthouse and drops sharply into the deep blue waters below. The western shoreline extends into a sandbar and can be walked. Much of Imalev’s interior habitat is characterised by prairie land, though there are some pockets of native vegetation. 

Though undeveloped beyond the maritime-army lighthouse, Imalev Island harbours natural water resources that could sustain residents. Future expansion is a real possibility.

10. Isla Focus ($600,000)

---

Link to original listing

• Location: Última Esperanza Sound, Magallanes
• Size: ~689.4 acres, 279 hectares
• Description: 24km SW of Puerto Natales, Approx 20km by boat from Puerto Natales port
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Puerto Natales is the doorway to Torres del Paine, and Isla Focus sits twenty-four kilometres from it, 279 hectares of Patagonian island in the Última Esperanza Sound, at the threshold of one of the most visited wilderness regions on earth.

The scale is the story. Two hundred and seventy-nine hectares for six hundred thousand dollars is among the lowest land costs of any titled island holding in the Americas, and the topography is described as unusually favourable for building, ample usable ground rather than the sheer rock that defines much of the fjordland.

Natural beaches front the property, and the surrounding channels open into the South Pacific. Mountains, glaciers and ice fields frame every horizon.

Puerto Natales provides an airport with regular flights, port ramps and full logistics support, which in Patagonia is the difference between an ambition and a project.

11. Isla Mutri ($385,000)

---

Link to original listing

• Location: Hualaihué fjords, Provincia de Palena, Los Lagos
• Size: ~61.8 acres, 25 hectares
• Description: 16km SW of Hornopirén, Approx 72km SSE of Puerto Montt
• Ownership: Freehold
• Development: Undeveloped
• See on Google Earth

Twenty-five hectares of Patagonian fjord island for under four hundred thousand dollars, Isla Mutri sits at a price point that has all but vanished from the private island market.

The island lies in the Hualaihué fjords of the Los Lagos region, sixteen kilometres southwest of Hornopirén and seventy-two from Puerto Montt, the gateway city for Chilean Patagonia. This is the northern fjordland, where temperate rainforest runs down to the water and the Andes rise directly behind it.

Mutri is carried by two independent brokers at the same figure, including Chile Sotheby’s, unusual corroboration in a market where island listings are so often single-sourced.

For a buyer who wants genuine Patagonian wilderness rather than a tropical postcard, and who would rather build than inherit, this is among the most accessible entry points anywhere in the region. Hornopirén connects to the Carretera Austral, Chile’s southern highway, bringing road access within reach of the shoreline.
