Patagonia is one of the most fascinating regions of South America, known for its dramatic mountains, enormous glaciers, remote lakes, and rugged wilderness. But where does Patagonia begin, and where does it end?
Patagonia is a vast geographic region spanning southern Chile and Argentina. Unlike a country with clearly defined political borders, Patagonia has no single universally agreed-upon boundary. Its northern limits vary depending on whether you're looking at geography, history, or local traditions.
In this guide, we'll explore where Patagonia begins and ends, how the region is divided between Chile and Argentina, and the towns, national parks, mountains, and glaciers that help define it. Whether you're planning a visit or considering a move to southern Chile, understanding Patagonia's geography is a great place to start.
Where is Patagonia?
Patagonia lies at the southern end of South America, spanning parts of Chile and Argentina. But exactly where is Patagonia, and where does it begin? There is no single universally accepted boundary. In Chile, the Bío-Bío River is sometimes used as a rough northern limit, while in Argentina, the Colorado River is often cited as a northern boundary. Patagonia extends south through the Andes, vast steppe landscapes, glaciers, and fjords toward Tierra del Fuego.
For those of us living in Chile, Patagonia is closer than many people realize. Traveling south from Puerto Montt, the landscape gradually changes into a world of remote fjords, forested mountains, turquoise lakes, and glaciers. The Aysén Region and the Magallanes Region are especially well known for their spectacular Patagonian scenery.
Chilean Patagonia
Chilean Patagonia is famous for its dramatic Andes mountains, deep fjords, temperate rainforests, turquoise lakes, and enormous glaciers. It stretches through southern Chile, where remote landscapes and small communities offer a very different experience from the country's more populated central regions.
The main regions associated with Chilean Patagonia include:
- Los Lagos Region – Often considered the gateway to Patagonia, with Puerto Montt as an important transportation hub, the Chiloé Archipelago, Lake Llanquihue, and access to the Carretera Austral.
- Aysén Region – One of Chile's least populated regions, known for its rugged mountains, rivers, glaciers, fjords, and extensive wilderness. Highlights include Coyhaique, Lago General Carrera, Laguna San Rafael National Park, and the Carretera Austral.
- Magallanes and Chilean Antarctica Region – Home to Torres del Paine National Park, the city of Punta Arenas, Puerto Natales, and Chile's portion of Tierra del Fuego.
The northern boundary of Patagonia varies depending on the definition being used. Some broader interpretations extend into areas farther north, including parts of Los Ríos or Araucanía, while many modern travel guides focus on the southern regions listed above.
Chilean Patagonia is wetter and more forested on the western side of the Andes, where the Pacific climate brings abundant rainfall. Farther east, the mountains give way to drier landscapes. For visitors and people considering a move to Chile, the region offers remarkable opportunities for hiking, kayaking, fishing, wildlife watching, and exploring rural communities.

Argentine Patagonia
Across the Andes from Chile, Argentine Patagonia stretches south from the region around the Colorado River toward Tierra del Fuego. It includes the provinces of Neuquén, Río Negro, Chubut, Santa Cruz, and parts of Tierra del Fuego. Its landscapes range from the dry Patagonian steppe and Atlantic coastline to the towering Andes, glacial lakes, and vast ice fields.
Some of the best-known destinations include:
- Bariloche – A popular mountain city on Lake Nahuel Huapi, known for its lakes, forests, skiing, and access to Nahuel Huapi National Park.
- Esquel and Trevelin – Towns in the Andes foothills offering mountain scenery, hiking, and access to Los Alerces National Park.
- El Chaltén – A trekking destination near Mount Fitz Roy and Cerro Torre, with spectacular mountain trails.
- El Calafate – The main gateway to Los Glaciares National Park and the famous Perito Moreno Glacier.
- Puerto Madryn – A coastal destination known for marine wildlife and access to the Valdés Peninsula.
- Ushuaia – A major city on the Argentine side of Tierra del Fuego, often promoted as one of the world's southernmost cities.
For people living in Chile, Argentine Patagonia offers an opportunity to experience the other side of the Andes. Border crossings connect some areas, but distances are substantial, and travel times depend on the route, road conditions, and season. Check current border requirements before setting out.
Tierra del Fuego: The Edge of the World
At the southern end of South America lies Tierra del Fuego, an archipelago divided between Chile and Argentina by an international boundary. Its landscapes include windswept grasslands, rugged mountains, forests, glaciers, and remote channels.
On the Argentine side, Ushuaia is a well-known base for exploring the Beagle Channel and Tierra del Fuego National Park. On the Chilean side, the archipelago extends across a much larger and more remote area, including parts of the island of Tierra del Fuego and numerous smaller islands and channels.
Tierra del Fuego is often described as Patagonia's final frontier, but it is not simply an empty wilderness. Communities, Indigenous histories, working settlements, and distinctive wildlife are all part of the region's story. For travelers, it offers a memorable look at the far southern reaches of Chile and Argentina.
Why Patagonia's Boundaries Are Flexible
Patagonia does not have one officially recognized northern boundary. Its limits vary depending on whether you're looking at geography, history, local traditions, or tourism. What most definitions share is the idea of a vast region shaped by the Andes, open steppe, glaciers, forests, and a strong connection to the natural world.
We sometimes get into friendly disagreements with locals on our Chile Expat Family YouTube channel about where Patagonia begins. Jim and I live near Puerto Octay in the Los Lagos Region, south of Puerto Montt. Some people consider our area part of Patagonia, while others draw the northern boundary farther south.
That's one reason this question is so interesting: people who live in the region may have different ideas about what Patagonia means. Rather than claiming that one boundary is correct for everyone, it's more useful to understand the different definitions and the landscapes they describe.
Patagonia for Expats Living in Chile
For expat families living in Chile, Patagonia offers extraordinary opportunities for exploration, outdoor activities, and discovering some of South America's most spectacular landscapes.
- Hiking and trekking — Explore trails in Torres del Paine National Park, the Cerro Castillo area, and along the Carretera Austral.
- Wildlife watching — Look for condors, guanacos, whales, dolphins, and penguins, depending on the location and season.
- Cultural experiences — Visit small fishing communities, learn about local traditions, and discover the region's Indigenous histories.
- Outdoor adventures — Enjoy kayaking through fjords, glacier excursions, fishing, camping, and scenic road trips.
You don't have to travel from Santiago to experience the journey south. From our home in the Los Lagos Region, Patagonia and the Carretera Austral are part of the wider world of southern Chile that we continue to explore.
If you're considering moving to Chile, visiting southern Chile before making a decision can also help you understand its climate, distances, services, and rural lifestyle.
Conclusion: Where Does Patagonia Begin?
So, where does Patagonia begin? The answer depends on the definition you're using. The Bío-Bío River is sometimes cited as a northern limit in Chile, while the Colorado River is commonly used as a rough boundary in Argentina. Neither defines a universally accepted border.
What is clear is that Patagonia is an extraordinary region shared by Chile and Argentina, stretching through mountains, forests, steppe, lakes, glaciers, and the islands of the far south.
For us, living in southern Chile means being close to landscapes that make this part of the world so special. Whether you call the area where you live Patagonia or simply southern Chile, the best way to understand the region is to explore it for yourself.
