Scenery
The Carretera Austral is a symphony of green and blue. Expect ancient Valdivian rainforests, towering fjords carved by glaciers, vibrant turquoise rivers fed by meltwater, and dramatic hanging glaciers like Ventisquero Colgante in Queulat National Park. The landscape is intensely lush, often misty, and constantly evolving, with volcanoes peeking through clouds. Every bend reveals a new, breathtaking vista of untouched wilderness, from the marble caves of Puerto Río Tranquilo to the majestic General Carrera Lake. Ruta 40 offers a starkly different, yet equally awe-inspiring, panorama. It traverses the vast, arid Patagonian steppe, characterized by golden grasses, sparse vegetation, and wide-open skies that stretch to the horizon. In the distance, the jagged peaks of the Andes provide a dramatic backdrop, culminating in the iconic granite spires of Mount Fitz Roy near El Chalten and the colossal ice formations of Perito Moreno Glacier near El Calafate. The beauty here lies in its immense scale, the dramatic light, and the raw, untamed feel of the high desert.
Activities
The Carretera Austral is a paradise for active adventurers. Opportunities abound for world-class trekking (Cerro Castillo, Jeinimeni National Park), kayaking (Marmol Caves, fjords), white-water rafting on rivers like Futaleufú, fly-fishing, and exploring remote national parks. Glacier hiking and boat trips to Ventisquero Colgante or Laguna San Rafael are highlights. It's about immersion in nature, often with fewer crowds and a greater sense of discovery. Ruta 40 provides access to some of Patagonia's most iconic experiences. El Chalten, the 'National Capital of Trekking,' offers unparalleled hikes to Laguna de los Tres (Fitz Roy) and Laguna Torre. Near El Calafate, the Perito Moreno Glacier demands attention with ice trekking, boat tours, and viewing from extensive boardwalks. Other activities include exploring Cueva de las Manos (ancient cave paintings), visiting Welsh settlements in Chubut, and various outdoor pursuits, often with more structured tour options available.
Accommodation
Accommodation options along the Carretera Austral tend to be smaller, more rustic, and locally run. Expect charming cabins (cabañas), guesthouses (hospedajes), campsites, and eco-lodges. Larger towns like Coyhaique and Futaleufú offer more choices, but booking ahead, especially in peak season, is crucial due to limited availability in remote areas. Camping is a popular and rewarding option for self-drivers. Ruta 40, particularly in its southern section, boasts a wider range of accommodation, from budget hostels and campsites to luxurious hotels and estancias (working ranches). Key tourist hubs like El Calafate and El Chalten have extensive options to suit all budgets. Even smaller towns often have several hotels or guesthouses, making last-minute bookings somewhat easier, though popular spots fill up.
Food & Dining
Food along the Carretera Austral emphasizes fresh, local produce and traditional Chilean Patagonian fare. Expect excellent seafood (salmon, king crab), succulent lamb (cordero al palo), locally grown fruits (berries), and hearty stews. Dining options are simpler, often in family-run restaurants or 'cocinerias.' Self-catering is highly recommended by stocking up in larger towns like Coyhaique. Argentine Patagonia on Ruta 40 is renowned for its succulent Patagonian lamb (cordero), superb beef, and regional specialties like empanadas and dulce de leche. Malbec wine is also widely available. Tourist centers like El Calafate and El Chalten have diverse restaurant scenes, from casual parrillas to upscale dining. Groceries are readily available in most towns, making self-catering convenient for self-drive travelers.
Cost Comparison
The Carretera Austral can be surprisingly expensive due to its remoteness. Fuel prices are higher, and groceries in smaller towns can carry a premium. While accommodation might be simpler, limited competition can keep prices firm. Ferry crossings, though picturesque, add to the cost. Budget for higher daily expenses, especially if relying solely on restaurants. Costs on Ruta 40 are generally comparable, but can be more variable. Fuel might be slightly cheaper than in Chile. Accommodation in tourist hubs can range from budget to luxury. Park entrance fees (e.g., Los Glaciares National Park) can be significant. However, self-catering is easier and often cheaper in larger Argentine towns, potentially lowering overall food costs. Strategic planning and vehicle choice can help manage expenses on both routes.
Accessibility
Accessing the Carretera Austral often involves flying into Puerto Montt or Balmaceda (Coyhaique). The route itself is challenging for self-drive, with long stretches of gravel (ripio) and mandatory car ferry crossings (e.g., from Hornopirén to Caleta Gonzalo, or from Puerto Yungay to Río Bravo). While navigable with a 2WD, a 4x4 or high-clearance vehicle is recommended for comfort, safety, and peace of mind on the rough terrain. Public transport is available but infrequent and can be slow. Ruta 40 is generally more accessible. Major airports include El Calafate (FTE) and Bariloche (BRC). The southern section, connecting El Chalten and El Calafate, is fully paved and easy to drive. While other sections, particularly further north, can have gravel, the overall driving experience is smoother and faster. Public bus services are regular between major towns, offering a good alternative to self-drive if preferred.
Weather
Expect temperate rainforest climate along the Carretera Austral: cool, wet, and often unpredictable. Summers (Dec-Feb) bring milder temperatures (10-20°C) but still a good chance of rain. Winters are cold and very wet, with snow in higher elevations. Packing waterproof gear and layers is essential any time of year. Days can be overcast, adding to the dramatic, moody scenery. Ruta 40, especially in the south, experiences a drier, more continental climate. Summers are generally warmer (15-25°C) with more sunshine, but strong, relentless Patagonian winds are a defining feature. Winters are cold, with snow and ice, particularly in the mountain passes. Be prepared for significant temperature swings between day and night, and always account for the wind factor, which can impact driving conditions.

Choosing between the Carretera Austral and Ruta 40 depends entirely on your travel style and priorities. If you crave raw, untamed wilderness, off-the-beaten-path adventure, and don't mind challenging roads for the reward of pristine nature and fewer crowds, the Carretera Austral is your dream. It's for those who want to immerse themselves in Chile's lush, fjord-filled Patagonia, a truly unforgettable self-drive journey. However, if your vision of Patagonia includes iconic glaciers, world-famous trekking, generally smoother roads, and more developed infrastructure with easier access to well-known landmarks, then Argentina's Ruta 40, particularly its southern stretch, will be more to your liking. It offers grand vistas and comfortable travel to bucket-list destinations. For the ultimate Patagonian experience that captures the diverse beauty of this region, consider combining both.
Combine Both Destinations
Combining these two epic routes is not only possible but highly recommended for the ultimate Patagonian adventure. A common strategy for self-drivers is to drive a section of one, cross the border, and continue on the other. For example, after exploring the northern Carretera Austral (e.g., up to Futaleufú), you could cross into Argentina to connect with Ruta 40 northbound towards Bariloche, or if in the south, cross between Chile Chico (Carretera Austral) and Los Antiguos (Ruta 40) to continue towards El Chalten/El Calafate. Allow at least 2-3 weeks, ideally more, to truly appreciate both, accounting for border crossings and varying road conditions. Renting a car with international permit is essential for a seamless cross-border experience.
Car Rental Advice
Self-driving is the absolute best way to experience both the Carretera Austral and Ruta 40, offering unparalleled freedom and flexibility. For the Carretera Austral, a 4x4 or high-clearance 2WD vehicle is strongly advised due to extensive gravel (ripio) sections, which can be rough and sometimes muddy. Ensure your rental includes spare tires and a jack, and consider additional insurance for gravel roads. On Ruta 40, especially the southern part connecting El Chalten and El Calafate, a standard 2WD sedan is perfectly adequate for paved sections. However, an SUV offers more comfort on any gravel detours and provides better visibility. When renting, explicitly state your intention to cross international borders. You'll need an international driving permit, your home country's license, and specific cross-border authorization documents from the rental company, which must be arranged in advance (typically incurring a fee of around $100-200 USD). These documents are mandatory for insurance and border officials. Always check fuel levels as gas stations can be sparse, especially on the Carretera Austral and remote Ruta 40 sections, and carry cash for small towns and ferries.

Frequently Asked Questions
Which route is better for first-time Patagonia visitors?
Ruta 40 is often recommended for first-timers due to its easier access to iconic landmarks like Perito Moreno and Fitz Roy, generally smoother roads, and more developed tourist infrastructure. The Carretera Austral offers a more rugged and off-the-beaten-path experience, better suited for those seeking a deeper dive into wild nature.
Do I need a 4x4 for both routes?
A 4x4 or high-clearance vehicle is highly recommended for the Carretera Austral, where large sections are gravel (ripio) and can be rough. For Ruta 40, particularly the southern paved sections, a standard 2WD car is sufficient. However, an SUV or 4x4 provides more comfort and capability for exploring gravel side roads or tackling unpaved northern sections of Ruta 40.
How long does it take to drive each route?
Driving the full Carretera Austral (approx. 1,240 km / 770 miles) typically takes 10-14 days, including time for activities and ferry crossings. The southern section of Ruta 40 (e.g., from Bariloche to El Calafate, approx. 1,400 km / 870 miles) can be done in 5-7 days of driving, but you'll want at least 3-5 extra days for hiking around El Chalten and visiting Perito Moreno.
Can I cross the border between Chile and Argentina with a rental car?
Yes, but you must arrange cross-border authorization with your rental company well in advance (typically 7-10 days). This usually involves an extra fee and ensures you have the necessary documentation (permiso de salida or authorization letter) required by border officials and for insurance purposes in the other country. Without it, you will be denied crossing.
Which route is more budget-friendly?
Both routes can be expensive due to their remoteness. The Carretera Austral can have higher fuel and grocery costs in smaller towns due to limited supply. Ruta 40 offers more variety in accommodation and food prices in larger towns, potentially allowing for more budget control, but major park entrance fees (e.g., Los Glaciares National Park) can add up. Overall, they are broadly comparable, with diligent planning helping on both.
When is the best time to visit both routes?
The Austral summer (December to March) is the most popular time due to milder weather, longer daylight hours, and all services being open. However, this is also peak season, meaning more crowds and potentially higher prices. Shoulder seasons (November, April) offer fewer crowds and potentially lower prices, but with slightly more unpredictable weather.
Is wild camping allowed along these routes?
While not strictly 'legal' everywhere, wild camping (boondocking) is widely tolerated and practiced along both routes, especially in more remote areas, provided you are respectful of private property, adhere to Leave No Trace principles, and avoid national park boundaries where designated campsites are mandatory. Always check local regulations.
