Patagonia road trip 2026: a 14 day Chile and Argentina loop

Southern Patagonia is split between Chile and Argentina, and the best trips cross the border at least twice. The classic loop links Torres del Paine on the Chilean side with El Calafate and El Chaltén on the Argentine side, using the border posts at Cerro Castillo and Río Turbio.

This is different from the Carretera Austral, which runs further north through Chilean fjords and rainforest. This route is the steppe and the granite: drier, windier, and built around three or four major destinations rather than a continuous road.

How long it takes

Ten days covers Torres del Paine, El Calafate and El Chaltén at a reasonable pace.

Fourteen adds slack for weather, which in Patagonia is not optional. The Torres del Paine base viewpoint and the Fitz Roy trail from El Chaltén both need a clear day, and neither is guaranteed.

Seven days means picking two of the three and accepting that a bad-weather day costs you one of them.

When to go

December to February is peak summer: long daylight, warmest temperatures, all services open, and the strongest wind of the year.

November and March are the best compromise. Fewer people, less wind, still enough daylight, and most services running. March brings autumn colour.

April to September is winter. Many businesses close, some roads and park sections shut, and daylight is short. Torres del Paine stays open but on a limited basis.

Wind is the defining feature. Summer gusts routinely exceed 100 km/h on exposed roads, which affects driving on gravel and makes car doors genuinely dangerous to open carelessly.

The route

A loop from Punta Arenas, which has the best flight connections and car hire in the region.

Punta Arenas to Puerto Natales, around 250 km. Paved and straightforward. Puerto Natales is the base town for Torres del Paine: gear shops, restaurants and most of the region's accommodation.

Torres del Paine, three to four days. The park is the centrepiece. Day walks reach the base of the towers and Lago Grey; the W trek takes four to five days if you want the full route. Even without hiking, the road through the park is worth a full day.

Puerto Natales to El Calafate, around 270 km. Crosses into Argentina at Cerro Castillo. El Calafate is the base for the Perito Moreno glacier, one of the few glaciers in the world that is not visibly retreating, and the walkways bring you close enough to hear it calve.

El Calafate to El Chaltén, around 215 km. Along Lago Argentino and up Route 40. El Chaltén is a small village built for trekking, at the foot of Fitz Roy and Cerro Torre. The Laguna de los Tres trail is the classic day walk, long and steep at the end.

El Chaltén back to Punta Arenas, around 600 km. Two days with an overnight, re-crossing into Chile.

Crossing the border with a rental car

This is the detail that most often goes wrong, and it is worth handling before you book.

You need explicit permission from the rental company to take the vehicle between Chile and Argentina. It requires paperwork, usually costs extra, and often needs several days' notice. Turning up at the border without it means being turned back.

Allow time at the crossings. They are straightforward but not fast, and Chile has strict agricultural controls: no fresh fruit, vegetables, meat or dairy in either direction. Eat or bin them before you queue, because the fines are real.

Carry the vehicle documents, your passport and the rental authorisation together.

Roads and fuel

The main routes between the towns are paved. Route 40 in Argentina has long gravel sections in places, and the roads inside Torres del Paine are gravel throughout.

A standard car handles the paved sections. High clearance is more comfortable on the park roads and on Route 40's rougher stretches.

Fuel stations are far apart on the Argentine side in particular. Fill up in every town, and be aware that stations in small settlements occasionally run dry, which is why locals never pass one at half a tank.

Costs and logistics

Patagonia is expensive relative to the rest of both countries. Accommodation in El Chaltén and inside Torres del Paine books out months ahead for summer, and the in-park refugios especially so.

Argentina's currency situation makes payment complicated and changes often. Cards are widely accepted, but check current guidance close to your trip rather than relying on advice written a year earlier.

Common questions

Do I need to hike to make this worthwhile?

No. Perito Moreno, the road through Torres del Paine and the drive up to El Chaltén are all rewarding without a long walk. But the best of Fitz Roy and the towers requires a full day on foot.

One country or both?

Both. The two sides are genuinely different landscapes and the border crossings are manageable.

Can I take a rental car across the Chile-Argentina border?

Only with a permit arranged in advance by the rental company, plus the right insurance. It takes days to issue and costs extra, and without it you will be refused at the crossing. This is the single most common thing that derails a Patagonia drive.

When is the best time to visit Patagonia?

November to March, the southern summer. December to February is warmest and busiest; the shoulder months are quieter with more changeable weather.

How bad is the wind?

Genuinely strong, especially in summer, and it is the reason rental agreements warn about car doors. Open doors with a hand on them, and expect it to affect the car on exposed roads.

Is it better to fly between the towns?

There are flights between El Calafate and Punta Arenas, and skipping the long drive is reasonable if time is short. You lose the steppe, which some people are happy to lose.

Do I need to book Torres del Paine in advance?

Yes, if you want to stay inside the park. Accommodation there is limited and books out months ahead in summer, and some trails now require reserved entry.

Planning your version

Build the plan around the two weather-dependent days, not the driving. Give the planner your dates and where you want to walk, then keep a spare day near each of Torres del Paine and El Chaltén so a bad forecast does not cost you the reason you came.
