Ruta 40 (Patagonia Section) — Car Rental Guide
Embark on the ultimate Patagonian adventure by renting a car for Ruta 40. Navigate Argentina's legendary highway, discovering remote landscapes, glacial lakes, and vibrant towns at your own pace. Essential tips for vehicle choice, fuel, and road conditions included for an unforgettable journey.
Why Rent a Car Here
Renting a car for Ruta 40 transforms a mere trip into a true expedition. This iconic route is the backbone of Patagonia, connecting you to world-renowned national parks like Los Glaciares, Perito Moreno, and Lanín, as well as charming Andean towns and remote estancias. Public transport simply cannot grant you the freedom to explore at your whim, stopping for every breathtaking view, wildlife sighting, or hidden trailhead. A rental car gives you unparalleled flexibility to adapt to weather, explore off-the-beaten-path destinations, and create a truly personalized adventure, making every kilometer an integral part of your unforgettable Patagonian story. It's the only way to genuinely embrace the spirit of the open road in this magnificent wilderness.
Renting a car for the Patagonian section of Ruta 40 isn't just a convenience; it's an absolute necessity for truly experiencing the raw, untamed beauty of this incredible region. This legendary highway stretches over 5,000 kilometers from north to south, with its Patagonian segments offering some of the most dramatic and isolated landscapes on Earth. Relying on public transport here is impractical and severely limits your freedom to explore hidden gems, remote national parks, and spontaneous detours. With your own vehicle, you gain the flexibility to chase the perfect sunset over the Andes, linger at a pristine glacial lake, or simply pull over to marvel at the vast, desolate steppe.
Driving Ruta 40 is an adventure that demands respect for the elements and preparation for long stretches without services. Expect a mix of paved and gravel roads (ripio), sometimes intense Patagonian winds, and the need to carry extra fuel and supplies. This guide will equip you with all the essential information to choose the right vehicle, understand road conditions, and navigate the challenges, ensuring your Ruta 40 road trip is not just possible, but truly epic and safe.
Road Overview
Paved
Approximately 60-70% paved in the main Patagonian sections, with significant stretches of gravel (ripio), especially in the central and southern parts.
Main Routes
- RN40 North (e.g., Bariloche to Esquel)
- RN40 Central (e.g., Esquel to Perito Moreno)
- RN40 South (e.g., Perito Moreno to El Calafate)
- RN40 Branch to El Chaltén (RN23/RN40)
Conditions
Road conditions vary widely from smooth asphalt to rough, washboard gravel (ripio). Expect long, straight, often windswept sections. Wildlife, especially guanacos and rheas, are common road hazards. Services (fuel, food, lodging) can be extremely sparse, with stretches of 200km or more between towns. Cell signal is often nonexistent for hours.
Vehicle Recommendations
| Vehicle Type | Suitability | Price Range | |
|---|---|---|---|
| 4wd | Highly recommended for comfort, safety, and navigating challenging ripio sections, especially if exploring off the main route or in adverse weather. Higher ground clearance and robust suspension are invaluable. | $100-200 USD/day | Recommended |
| suv | A strong second choice, offering good ground clearance and comfort for both paved and gravel sections. Many SUVs are 2WD but still provide a much better experience than a standard car on Patagonian roads. | $70-150 USD/day | |
| pickup | Excellent for groups or those carrying extra gear (camping, extra fuel). Offers superb robustness and often 4WD capability, making it ideal for the most rugged parts of Ruta 40. | $90-180 USD/day | |
| sedan | Only suitable for very specific, short, and known paved sections of Ruta 40. Not recommended for the full Patagonian experience due to low clearance, poor performance on gravel, and increased risk of damage. | $40-70 USD/day |
Fuel Information
- Availability
- Fuel stations are sporadic, sometimes hundreds of kilometers apart. Always fill up whenever possible, even if your tank is half full. Some smaller stations may run out of fuel, especially during peak season.
- Prices
- Expect prices around $1.00-1.50 USD/liter for gasoline (nafta) and diesel (gasoil). Prices can fluctuate and are generally higher in remote areas.
- Tips
- Carry at least one 10-liter jerrican (fuel canister) for emergencies, especially on the longer, emptier stretches. Always check your fuel gauge and plan your stops meticulously. Be aware that some small towns only have limited hours for fuel sales.
Parking Information
- Availability
- Parking is generally abundant and free in most towns, national parks, and roadside pull-offs along Ruta 40. Designated parking lots are available at major tourist attractions.
- Costs
- Mostly free. Some national park entrances may charge a fee for vehicle entry (separate from the entrance fee per person). Occasional paid parking might be found in larger cities like Bariloche or El Calafate's town centers.
- Tips
- When parking in towns, always secure your vehicle and do not leave valuables visible. In remote areas, ensure your car is safely off the main road and visible to other drivers, especially at dusk or night. Overnight parking is usually safe at hotels/hostels.
Insurance Advice
Given the mixed road conditions, long distances, and potential for wildlife encounters, comprehensive insurance is crucial. Opt for full coverage (CDW/LDW with zero or low deductible) that specifically includes gravel/underbody damage. Many standard policies exclude damage incurred on unpaved roads, so verify this with your rental company. Consider third-party liability insurance for peace of mind, although it's often included. Documenting your car's condition with photos/videos before departure is also highly recommended.
Local Driving Rules
- 1Headlights must be on at all times, even during the day, on all national routes (including Ruta 40).
- 2Speed limits vary; typically 110 km/h on rural paved roads, 60 km/h in urban areas, and often lower on gravel (ripio) sections. Observe posted signs.
- 3Seatbelts are mandatory for all occupants.
- 4Yield to traffic from the right on unmarked intersections unless otherwise indicated.
- 5Passing is prohibited on solid yellow lines, hills, and curves.

Seasonal Considerations
summer
December to February. Generally the best time for driving, with long daylight hours and warmer temperatures. However, this is also the windiest season, and strong Patagonian winds can make driving challenging.
Be prepared for strong crosswinds, which can affect vehicle stability. Book accommodations and rental cars well in advance as it's peak tourist season. Carry plenty of water and sun protection.
autumn
March to May. Temperatures cool, and the famous Lenga trees display stunning fall colors. Winds tend to be less intense than in summer. Weather can be variable, with possibilities of early snow in late autumn in higher elevations.
Enjoy the beautiful scenery with fewer crowds. Pack layers as temperatures can change rapidly. Check weather forecasts, especially for mountain passes, as roads can become slippery with frost or light snow.
winter
June to August. Many parts of Ruta 40, especially in the south and high elevations, can be affected by snow and ice. Some sections or connecting roads may close temporarily. Strong winds and blizzards are possible.
Only undertake if you have experience driving in winter conditions and a 4WD vehicle. Carry snow chains and know how to use them. Many services and attractions may be closed. Check road status frequently (e.g., Vialidad Nacional).
spring
September to November. Weather is highly unpredictable, ranging from sunny days to strong winds and even late-season snow. Rivers and waterfalls are at their fullest from snowmelt.
Be prepared for all types of weather. Roads can be muddy or slippery after rain or snowmelt. Keep an eye out for emerging spring wildflowers. Fewer crowds than summer, but services begin to open up.
