Remote Islands in South America That Feel Like Another World

South America is famous for its dramatic mountains, enormous rainforests, colorful cities, and long stretches of coastline. But beyond the better-known destinations are islands where the pace of life changes completely. Some are separated from the mainland by hundreds of kilometers of ocean, while others are hidden among fjords, forests, glaciers, or tropical waters.

These remote islands can feel almost unreal. You might find penguins walking along deserted beaches, volcanic landscapes rising from the Pacific, tiny communities surrounded by endless water, or forests where the only sounds are birds and waves. For travelers looking for places that feel genuinely different from ordinary tourist destinations, South America’s islands offer plenty of possibilities.

1. Robinson Crusoe Island, Chile

Robinson Crusoe Island is part of Chile’s Juan Fernández Archipelago, located far out in the Pacific Ocean. Its isolation is one of its greatest attractions, but the island’s rugged scenery makes the journey even more worthwhile.

Steep mountains, narrow valleys, dense vegetation, and rocky coastlines dominate the landscape. Unlike the polished feel of many popular island destinations, Robinson Crusoe feels wild and adventurous.

The island is also associated with the famous story of Alexander Selkirk, the sailor whose experience of isolation helped inspire Daniel Defoe’s Robinson Crusoe. Walking through the island’s dramatic terrain makes it easy to understand why the location became connected with one of literature’s most famous tales of survival.

2. Alejandro Selkirk Island, Chile

If Robinson Crusoe Island feels remote, Alejandro Selkirk Island takes that feeling even further. It is the most distant major island in the Juan Fernández Archipelago and is characterized by steep mountains and rugged terrain.

There are no sprawling resorts or busy tourist districts here. Instead, visitors encounter dramatic scenery, small settlements, hiking routes, and an extraordinary sense of isolation.

The island’s mountainous landscape rises sharply from the ocean, creating views that seem more suited to a remote expedition than a conventional holiday. It is an ideal destination for travelers who enjoy nature, hiking, solitude, and places that remain largely outside the mainstream tourism circuit.

3. Easter Island, Chile

Few islands in the world have a landscape and cultural identity as distinctive as Easter Island, also known as Rapa Nui. Located in the southeastern Pacific Ocean, the island is famous for its enormous moai statues, but there is much more to discover beyond these iconic monuments.

Volcanic craters, grassy hills, dramatic cliffs, caves, beaches, and ancient ceremonial sites create a landscape unlike almost anywhere else in South America.

Rapa Nui’s distance from mainland South America contributes to its otherworldly atmosphere. The island feels separated from the ordinary rhythms of continental life, while its Polynesian heritage gives it a cultural character that is very different from Chile’s mainland.

4. Chiloé Island, Chile

Chiloé may not be as isolated as some of the islands farther into the Pacific, but it can still feel like another world. Located in southern Chile, Chiloé is known for its distinctive wooden architecture, green landscapes, seafood traditions, folklore, and strong island culture.

Misty mornings, rolling hills, forests, quiet beaches, and colorful houses give the island a personality of its own. Small villages and traditional markets offer a slower experience compared with Chile’s major cities.

Travelers can explore historic wooden churches, visit coastal communities, hike through national park landscapes, and sample local dishes. Chiloé is particularly appealing to travelers who want an authentic cultural experience rather than an isolated beach resort.

5. Wellington Island, Chile

Deep in Chilean Patagonia lies Wellington Island, part of one of the world’s most complex coastal landscapes. The island is surrounded by channels and fjords and forms part of the remote Patagonian wilderness.

Here, the landscape is defined by mountains, glaciers, forests, cold waters, and unpredictable weather. Much of the region is difficult to access, making it a destination more suited to adventurous travelers and expedition-style journeys.

The sense of scale can be overwhelming. Mountains appear to rise directly from the water, while remote waterways stretch between seemingly endless stretches of wilderness.

6. Tierra del Fuego, Argentina and Chile

Tierra del Fuego is not a single isolated island experience, but the world’s southernmost inhabited region contains some of the most remote island landscapes in South America. Divided between Argentina and Chile, the archipelago sits near the southern tip of the continent.

Forested mountains, glaciers, windswept coastlines, lakes, and channels create a landscape that can look almost Antarctic. The weather can change quickly, adding to the area’s wild character.

For travelers exploring the region, the surrounding islands and waterways offer opportunities to experience landscapes far removed from crowded tourist routes. It is one of the best areas in South America for travelers who want dramatic wilderness rather than tropical island scenery.

7. Isla de los Estados, Argentina

Isla de los Estados lies east of Tierra del Fuego and is one of Argentina’s most isolated islands. Its dramatic combination of mountains, forests, cliffs, bays, and rough seas gives it an almost mythical atmosphere.

The island has a fascinating maritime history and was once associated with navigation through the challenging waters around the southern tip of South America.

Today, its remote location and protected natural environment make it particularly interesting to people fascinated by wild landscapes. This is not the kind of island where visitors arrive expecting beach bars and souvenir shops. It is a place defined by wilderness.

8. Navarino Island, Chile

Located south of the Beagle Channel, Navarino Island sits in one of the world’s most spectacular southern landscapes. The island is home to Puerto Williams, often described as one of the world’s southernmost cities.

Beyond the settlement, the island offers mountains, forests, lakes, and rugged coastlines. The famous Dientes de Navarino range provides an especially dramatic backdrop for adventurous hikers.

What makes Navarino Island special is the combination of remoteness and accessibility. You can experience an extremely isolated part of Patagonia while still having a small community from which to organize activities and explore the surrounding wilderness.

9. Galápagos Islands, Ecuador

The Galápagos Islands are more famous than most destinations on this list, but they still deserve a place here because of how different they feel from the mainland. Located roughly 1,000 kilometers off Ecuador’s coast, the archipelago is renowned for its unique wildlife and volcanic landscapes.

Giant tortoises, marine iguanas, sea lions, penguins, and unusual bird species are among the animals that make the islands extraordinary. The landscapes range from black volcanic rock and barren lava fields to green highlands and beaches.

What makes the Galápagos feel like another world is not simply its distance. It is the feeling that evolution created an entirely separate chapter of life here.

10. Fernando de Noronha, Brazil

Far from Brazil’s crowded mainland beaches, Fernando de Noronha is an Atlantic island archipelago known for spectacular scenery and protected marine environments.

Clear water, volcanic rock formations, secluded beaches, cliffs, and abundant marine life create an experience that feels dramatically different from mainland Brazil.

The islands are environmentally protected, and visitor access is regulated. That helps preserve the natural character of the destination and prevents it from becoming another heavily developed beach resort.

11. Ilha do Marajó, Brazil

Marajó is a massive island at the mouth of the Amazon River and offers an experience unlike the tropical island image many travelers have in mind.

Instead of focusing purely on beaches, Marajó is known for wetlands, waterways, rural landscapes, wildlife, traditional communities, and Amazonian culture. The island’s size means that different parts offer very different experiences.

For travelers interested in exploring beyond conventional tourist routes, Marajó provides a fascinating combination of island life and Amazonian landscapes.

12. Santa Cruz Island, Ecuador

Santa Cruz is one of the main inhabited islands of the Galápagos, but its interior can still feel remarkably remote. Outside the developed areas, travelers encounter highlands, lava formations, agricultural landscapes, and giant tortoise habitats.

The contrast between the small towns and the surrounding wild environment is part of the island’s charm. Within a relatively short journey, you can move from cafés and local shops into landscapes where giant tortoises roam freely.

13. Islas de los Frailes, Peru

Peru’s Pacific coastline contains numerous islands and rocky offshore landscapes that are easily overlooked by international travelers. Some are important habitats for seabirds and marine wildlife rather than conventional tourist destinations.

The contrast between Peru’s desert coastline and its offshore islands can be striking. Dry, almost lunar landscapes meet cold Pacific waters, creating scenery that feels very different from the lush tropical islands found elsewhere in South America.

Why South America’s Remote Islands Feel So Different

There is something psychologically powerful about reaching an island that is separated from everyday life by a stretch of ocean. The journey itself becomes part of the experience.

On remote South American islands, you are more likely to encounter small communities, protected ecosystems, unusual wildlife, traditional cultures, dramatic weather, and landscapes that have not been heavily transformed for tourism.

Some islands are tropical. Others are cold, mountainous, windswept, or volcanic. What connects them is the feeling of separation. They remind travelers that there are still places where nature sets the pace.

How to Travel Responsibly to Remote Islands

Remote destinations are often environmentally fragile, so responsible travel matters. Visitors should respect wildlife, follow local regulations, avoid leaving waste behind, and support locally owned accommodation, guides, restaurants, and services whenever possible.

It is also important to research transportation before traveling. Some islands have limited ferry services, irregular flights, restricted visitor numbers, or weather-dependent connections. A little planning can prevent a remote adventure from becoming a logistical nightmare.

Final Thoughts

South America’s remote islands prove that you do not always need to travel to another continent to feel completely disconnected from familiar surroundings. From the volcanic isolation of Rapa Nui to the wild channels of Patagonia and the extraordinary ecosystems of the Galápagos, these islands offer landscapes and cultures that feel almost detached from the rest of the world.

For adventurous travelers, that isolation is precisely the attraction. These are places where the journey can be challenging, the weather unpredictable, and the comforts limited—but where the reward is an experience that feels genuinely unlike ordinary travel.

If you are searching for remote islands in South America, these destinations are a reminder that some of the continent’s most memorable adventures begin where the mainland ends.
