Traveling overland from Ushuaia to Punta Arenas is not just a transfer between two cities—it is a full Patagonian journey. Along the way, you cross borders, seas, endless steppe landscapes, and some of the most isolated regions of the continent. It is a trip that combines paved roads, gravel sections, a ferry crossing, and long distances where the landscape becomes the true protagonist.

This article explains how to make the journey step by step, which routes are taken, how long it takes, which towns appear along the way, and what is worth stopping to explore.

A unique journey: crossing from Argentina to Chile through Tierra del Fuego

Although Ushuaia and Punta Arenas are relatively close on the map, the overland journey requires circling much of Tierra del Fuego and crossing the Strait of Magellan.

Approximate total distance: Between 600 and 650 km depending on the route

Total travel time: Between 10 and 12 hours of real travel time, including ferry and border crossings

Section 1: Ushuaia → Río Grande

National Route 3 and the heart of Tierra del Fuego Island

The journey begins leaving Ushuaia via National Route 3, the only road that crosses the island from south to north. In total, we have 210 km from Ushuaia to Rio Grande, in a paved road in good condition

What you will see?

Along the journey through Tierra del Fuego, these landscapes unfold in an almost cinematic sequence. The Carbajal Valley appears as a vast plain surrounded by mountains, crossed by peatlands and waterways that reflect the sky on clear days. Shortly after, the road climbs to Garibaldi Pass, one of the most impressive viewpoints on the island, offering a privileged view of Lago Escondido nestled between the mountains. As you descend, the scenery transforms once again, giving way to dense Fuegian forests, dominated by lenga and southern beech trees, which turn into vibrant colors during autumn. Finally, the route passes through extensive peat bog areas, unique landscapes formed by organic material accumulated over thousands of years, giving this southern region its distinctive character.

As you head north, the landscape changes: forests gradually disappear and give way to open steppe.

Recommended stop: Tolhuin

Tolhuin: a small town by Lago Fagnano, ideal for a break. Located almost exactly in the middle of the island, Tolhuin is often described as the “heart of Tierra del Fuego.” But beyond its geographic position, it’s a place that offers a different pace, a quieter atmosphere, and a strong connection with nature—something that immediately stands out when traveling between Ushuaia and Río Grande.

What makes Tolhuin special is its setting. The town sits on the shores of Lago Fagnano, one of the largest lakes in Patagonia, surrounded by forests, mountains, and wide open spaces. After driving through the winding roads and dramatic landscapes of southern Tierra del Fuego, arriving here feels like a pause—an invitation to slow down.

Unlike Ushuaia, which is more developed and tourism-driven, Tolhuin retains a more local, authentic character. It’s a small town, simple in structure, but rich in atmosphere. Life here moves at a different rhythm, shaped by the lake, the forest, and the changing Patagonian weather.

One of the most iconic stops in Tolhuin is the Bakery La Unión, a classic meeting point for travelers crossing the island. It’s the kind of place where people stop not just for food, but for the experience—warming up with a coffee, enjoying fresh pastries, and sharing stories with other travelers making the same journey.

For those who have more time, Tolhuin offers several outdoor activities. Walking along the shores of Lago Fagnano is one of the simplest yet most rewarding experiences. The landscape is open, calm, and often windswept, creating a strong sense of place. Fishing, kayaking, and hiking in nearby forests are also popular options.

The surrounding area is ideal for exploring. There are trails that lead into the forest, viewpoints over the lake, and less-traveled roads that reveal a quieter side of Tierra del Fuego. It’s also a good base for those looking to experience nature without the intensity of more remote or demanding destinations.

Tolhuin is not a place of big attractions—it’s a place of moments. A stop here, even if brief, adds something important to the journey: a sense of balance. It breaks the long drive, connects you with the landscape, and offers a glimpse into everyday life in one of the southernmost regions of the world.

In a route defined by distance and movement, Tolhuin is where you stop, breathe, and truly feel Tierra del Fuego.

Arriving to Rio Grande

Finally, you reach Río Grande, the largest city in the northern part of the island.

Río Grande: The Northern Gateway of Tierra del Fuego

As you continue north across Tierra del Fuego, the landscape gradually changes—and so does the feeling of the journey. After leaving behind the forests and mountains of the south, you eventually arrive at Río Grande, a city that represents a completely different side of the island. Located on the northeastern coast, along the shores of the Atlantic Ocean, Río Grande is the largest city in the Argentine portion of Tierra del Fuego. It is not a classic tourist destination like Ushuaia, but rather an important industrial and logistical hub, and that is precisely what gives it its unique identity.

The first thing that stands out when arriving in Río Grande is the landscape. The dense forests disappear, replaced by wide-open Patagonian steppe, where the horizon stretches endlessly and the wind becomes a constant presence. The terrain feels flatter, more exposed, and more raw—a different expression of Patagonia. The city itself has a practical, functional character. It grew around industry and production, particularly in electronics and manufacturing, and its urban layout reflects that purpose. However, beyond its industrial profile, Río Grande offers a glimpse into everyday life in one of the southernmost inhabited regions of the world. One of the most distinctive aspects of Río Grande is its relationship with the sea. The coastline is rugged and windswept, with dramatic views of the Atlantic. Walking along the shore, you quickly realize how powerful the elements are here—the wind, the cold water, and the vast openness create a strong and memorable atmosphere.

For many travelers, Río Grande serves as a strategic stop. It’s a place to refuel, rest, and prepare for the next stage of the journey toward the border and Chile. Services are more available here than in other parts of the island, making it an important logistical point. At the same time, the area around Río Grande has its own appeal, especially for those interested in nature and outdoor activities. The region is well known for fly fishing, particularly for sea trout in the Río Grande River, attracting anglers from around the world. Culturally, the city reflects the resilience of those who live in extreme conditions. Life here is shaped by strong winds, cold temperatures, and long winters, yet there is a sense of community and adaptation that becomes evident even during a short visit.

Río Grande may not be the highlight of a trip to Tierra del Fuego, but it plays an essential role in understanding the region. It represents the transition from the more touristic south to the vast and open landscapes of Patagonia—and it reminds you that this journey is not only about destinations, but about the spaces in between.

 

Section 2: Río Grande → San Sebastián Border Crossing

Heading toward the frontier

Distance: 80 km

From Río Grande, you continue along National Route 3 to the San Sebastián border crossing, where immigration procedures are completed to exit Argentina. This section features openlandscapes typical of Patagonian steppe.

From Río Grande to San Sebastián: The Last Stretch Across Tierra del Fuego

The journey from Río Grande to San Sebastián marks the final stretch across Argentine Tierra del Fuego before crossing into Chile. It is not a long distance—roughly 80 kilometers—but it carries a distinct feeling: you are leaving the island behind, heading toward a more remote and open landscape.

The route follows National Route 3, and unlike the southern part of the island, the scenery here is completely dominated by the Patagonian steppe. The forests are gone, replaced by vast, flat plains where the horizon seems endless. The wind becomes even more noticeable, often strong and constant, shaping the low vegetation and reinforcing the sense of exposure.

Traffic is usually light, and for long stretches, you may find yourself completely alone on the road. It’s a quiet drive, almost meditative, where the landscape unfolds slowly and without interruption. Along the way, it’s common to spot guanacos moving freely across the steppe, as well as birds adapted to this open environment.

As you approach San Sebastián, the surroundings become even more minimal. The border area itself is simple and functional, reflecting the remote nature of the region. This is where you complete the exit procedures from Argentina before continuing your journey into Chile.

Although it is a short segment, this part of the journey is meaningful. It represents a transition—not only geographically, but also in the character of the landscape. It’s the moment where Tierra del Fuego begins to feel behind you, and the vastness of southern Patagonia opens up ahead.

Section 3: Crossing into Chile and heading toward the Strait of Magellan

Once in Chile, the journey continues along secondary roads and then onto Route CH-257, which leads to the ferry crossing. Here, you will encounter gravel sections and areas with limited infrastructure.

From the border, the distance is approximately 120 km to the strait crossing

 

Section 4: Crossing the Strait of Magellan: The key moment of the journey

This is one of the most distinctive parts of the trip. Crossing the Strait of Magellan by ferry is one of the most distinctive and memorable moments of the journey. The main route connects Punta Delgada on the mainland with Bahía Azul on Tierra del Fuego, a short but essential crossing that takes approximately 20 to 30 minutes and operates several times a day. As you board the ferry, there is a clear sense of transition—you are not just continuing a road trip, but physically crossing one of the most historic and iconic waterways in the world. The winds can be strong, the waters often restless, and the landscape vast and open, reinforcing the feeling of being in a truly remote region. For those seeking an alternative, there is also a longer ferry option between Punta Arenas and Porvenir, which takes around 2 to 2.5 hours and offers a more extended navigation experience. Regardless of the option chosen, this crossing is unavoidable when traveling overland—it is a defining part of the route, where land gives way to sea, and the journey becomes even more immersive.

Section 5: Bahía Azul → Punta Arenas: Route CH-255 and Route 9

Once on the Chilean mainland, the journey continues north. When you arrive at Bahía Azul and step onto the Chilean mainland, the journey continues north along a route that truly defines the vastness of southern Patagonia. The drive follows Route CH-255, eventually connecting with Route 9, covering approximately 200 to 250 kilometers across an open and windswept landscape. This section of the trip feels completely different from the forested and mountainous scenery near Ushuaia. Here, the terrain becomes flat, expansive, and almost endless, dominated by the Patagonian steppe. The horizon stretches in every direction, with very few visual interruptions, reinforcing a strong sense of isolation.

Along the way, you will pass scattered sheep ranches (estancias), often marked by simple structures and large fenced areas that reflect the region’s rural economy. It is also common to encounter guanacos grazing freely, along with birdlife adapted to this open environment. The road itself is generally straightforward, but the constant wind and the sheer scale of the landscape demand attention and patience. This part of the journey is less about reaching a destination quickly and more about experiencing the immensity of Patagonia—an environment that feels raw, quiet, and profoundly untouched.

Arrival in Punta Arenas: Capital of Chilean Patagonia

Finally, you arrive in Punta Arenas, one of the most important cities in southern Chile.

It is a strategic hub in the Magallanes region and an ideal base for exploring:

• Strait of Magellan
• Magdalena Island (penguins)
• Puerto Natales and Torres del Paine

 

Punta Arenas is one of the most important cities in southern Chile and a key gateway to Patagonia. Located on the shores of the Strait of Magellan, it has a strong historical and maritime identity.
The city played a crucial role in navigation and trade before the Panama Canal was built. Today, it serves as a base for exploring places like Torres del Paine and Antarctica.
Its architecture reflects European influence, especially from Croatian settlers. The central square, Plaza Muñoz Gamero, is the heart of the city and a great starting point.
The waterfront offers beautiful views of the strait and often strong Patagonian winds. Nearby, you can visit Magdalena Island, home to a large colony of Magellanic penguins.
The climate is cool, windy, and unpredictable throughout the year. Punta Arenas combines history, culture, and access to some of the most remote landscapes on Earth.
