Speed Limits
Urban
40 km/h
Rural
110 km/h (paved routes), 60 km/h (gravel roads)
Gravel
60 km/h (recommended maximum, can be lower depending on conditions)
Enforcement
Speed cameras are present on RN40, particularly near town entrances and exits. Police checkpoints (gendarmaría) are common, especially on major routes, enforcing speed limits, documentation, and vehicle safety. Fines can be issued on the spot or sent to your rental company.
Vehicle Requirements
Explanation: While main paved roads are manageable with a sedan, an SUV provides better ground clearance for gravel side roads and improved stability against strong Patagonian winds. For winter conditions or exploring unpaved national park routes (like to Lago Mascardi or Tronador), a 4WD vehicle with good tires is strongly recommended.
Winter Requirements: From May to October, it is legally mandatory to use winter tires (M+S or dedicated snow tires) or carry snow chains when driving on mountain passes and certain routes in the Bariloche region, particularly towards Cerro Catedral or the Chilean border. Rental companies usually offer these as an add-on.
Snow Chains: Snow chains are essential for winter driving on icy or snowy roads, especially on routes to ski resorts or when mountain passes are affected by heavy snowfall. Learn how to fit them before you need them.
Driving Hazards
Wind
Strong westerly winds are common year-round, especially on open sections of RN40. Drive with caution, as gusts can affect vehicle stability, particularly for larger vehicles.
Animals
Wildlife, including deer, guanacos, cattle, and horses, can appear suddenly on roads, particularly at dawn, dusk, and in rural areas. Drive defensively and be prepared to stop. Collisions with animals are a significant risk.
Flooding
Heavy rainfall can lead to localized flooding, especially in low-lying areas or where mountain runoff crosses roads. Check weather forecasts, and avoid driving through deep water. Some unpaved roads can become impassable.
Ice
Black ice is a major hazard in winter, particularly on shaded sections of roads, bridges, and during early morning/late evening. Exercise extreme caution, reduce speed, and avoid sudden braking or steering.
Gravel
Many scenic routes and secondary roads are gravel (ripio). Loose gravel can cause loss of traction, increased stopping distances, and stone chips to your vehicle. Reduce speed, maintain a safe distance from other vehicles, and be aware of 'washboard' surfaces.
Seasonal Conditions
Summer
Generally dry and sunny, perfect for driving. Main roads are in excellent condition. Expect heavy tourist traffic on popular routes and at attractions.
Tips: Book accommodations and rental cars well in advance. Carry plenty of water. Be mindful of dust on gravel roads and maintain extra distance.
Autumn
Cooler temperatures, stunning fall foliage. Weather can be unpredictable, with sunny days transitioning to rain or early snow flurries in May, especially at higher elevations.
Tips: Roads are less crowded. Be prepared for changing weather; carry warm clothing and check forecasts, especially for mountain excursions.
Winter
Cold, snowy, and icy. Many roads, especially those leading to ski resorts or into national parks, require chains or winter tires. Road conditions can change rapidly.
Tips: Essential to have winter tires and/or chains. Check road status daily with Vialidad Nacional (National Roads Authority) or local tourism offices. Drive slowly and smoothly. Plan for slower travel times.
Spring
Melting snow and increasing rainfall. Roads can be wet or muddy, especially gravel routes. Wildlife becomes more active. Temperatures begin to rise.
Tips: Be aware of slippery surfaces from melting snow and rain. Roads might have potholes from winter damage. Enjoy the spring blooms and fewer crowds than summer.
Emergency Information
Breakdown
For mechanical breakdowns, contact your rental car company's roadside assistance first. If no specific service is provided, local mechanics are available in Bariloche. For minor issues, look for 'Gomerías' (tire shops) for tire repairs.
Police
Emergency number 911 (general emergencies) or 101 (police specific). Gendarmería Nacional (National Gendarmerie) patrols major routes, while Policía de Río Negro handles local incidents.
Towing
Local towing services are available in Bariloche. Your rental company will typically arrange this. If stranded in a remote area, cell coverage might be an issue, so flag down passing vehicles for help if safe to do so.
Cell Coverage
Good in Bariloche city and along major paved routes (RN40). Coverage can be spotty to non-existent on secondary gravel roads, inside national parks, and in remote valleys. Always inform someone of your itinerary if exploring off main roads.
Parking Guide
In Bariloche city center, parking is mostly paid 'Estacionamiento Medido'. You purchase hours via an app or from authorized vendors (kiosks). Free street parking can be found further from the center but can be scarce. For attractions outside the city (e.g., Cerro Campanario, Llao Llao), designated parking lots are usually available, some free, some paid. Overnight parking is generally safe in well-lit areas or hotel parking lots.

Frequently Asked Questions
Are snow chains mandatory in Bariloche during winter?
Yes, from May to October, it is legally mandatory to carry and often use snow chains or have approved winter tires (M+S or dedicated snow tires) on many routes in the Bariloche region, especially when heading to ski resorts like Cerro Catedral or crossing mountain passes.
What kind of vehicle is best for driving around Bariloche?
For paved main roads, a sedan is sufficient. However, for exploring gravel side roads, venturing into national parks, or for better comfort and stability against winds, an SUV is highly recommended. For winter or more adventurous unpaved routes, a 4WD is ideal.
Is cell phone coverage reliable on Patagonian roads near Bariloche?
Cell phone coverage is generally good within Bariloche city and along major paved sections of RN40. However, it can become very limited or non-existent on secondary gravel roads, in valleys, and deeper inside national parks. Always be prepared for areas without signal.
How often should I refuel when driving outside Bariloche?
It's always wise to refuel whenever you see a petrol station, especially before embarking on longer journeys. While major routes have stations every 50-100 km, some stretches, particularly heading south on RN40 or into more remote areas, can have gaps of up to 120 km. Don't let your tank fall below half.
What should I do if I encounter wildlife on the road?
Drive cautiously, especially at dawn, dusk, and in rural areas. Reduce speed and be prepared to brake. If an animal is on the road, honk your horn gently from a distance to encourage it to move, but avoid sudden maneuvers that could cause you to lose control.
Are there speed cameras in and around Bariloche?
Yes, there are speed cameras (radars) present, particularly on RN40 as you approach and depart from Bariloche, and in some urban areas. Police checkpoints are also common, enforcing speed limits and general vehicle regulations.
What are the common road hazards beyond winter conditions?
Besides winter ice and snow, common hazards include strong crosswinds (especially on open stretches of RN40), loose gravel on unpaved roads, sudden appearance of wildlife (cattle, horses, deer), and occasional potholes on older paved sections. Dust can also be an issue on dry gravel roads.
Is it safe to drive at night in the Bariloche region?
Driving at night is generally not recommended outside urban areas, especially on rural or unpaved roads. Visibility is significantly reduced, increasing the risk of encountering wildlife, not seeing potholes or other road damage, and making it harder to navigate unfamiliar terrain. Stick to daylight driving for safety.
