Overview
The Carretera Austral — or Route 40's far-southern counterpart — is often confused with its more famous Chilean namesake, but Argentina has its own version of deep Patagonian road travel running through the provinces of Neuquén, Río Negro, Chubut, and Santa Cruz. The region commonly referred to as Argentina's 'Carretera Austral' corridor encompasses the remote lake district and Andean foothills south of Bariloche, extending through destinations such as El Bolsón, Esquel, and the Carretera Austral–adjacent zone near Los Alerces National Park and beyond.
This is a landscape of extreme contrasts: dense Valdivian temperate rainforest on western slopes, open Patagonian steppe to the east, turquoise glacial rivers, and peaks draped in permanent snow. Infrastructure is deliberately sparse, which is precisely why travelers who make the effort are rewarded with genuine solitude and landscapes largely unchanged for centuries.
Many travelers combine Argentine and Chilean sections of the broader Patagonian route, crossing at multiple border passes. The journey itself — whether by car, motorcycle, bicycle, or occasional bus — is as much the destination as any single point along the way. Road conditions vary enormously by season; some stretches are paved, many are ripio (gravel), and certain passes close entirely in winter.
Before You Go
Visas and Entry
Entry requirements depend on your nationality. For current visa rules, check TravelerPulse's Visas section and the official Argentine immigration authority (Dirección Nacional de Migraciones) at migraciones.gob.ar.
Health and Vaccinations
No mandatory vaccinations are required for most travelers entering Argentina. Hantavirus is present in rodent populations across Patagonia; avoid disturbing rodent nests or sleeping directly on open ground. Bring adequate sun protection — UV levels at altitude and in glacial environments are intense even on overcast days. Carry a personal first-aid kit, as medical facilities are widely spaced along this route.
Practical Preparation
- ATMs are rare: Stock up on Argentine pesos in Bariloche, Esquel, or Comodoro Rivadavia before heading into remote sections. Verify current cash availability locally, as the currency situation in Argentina can change.
- Fuel stops: Plan fuel carefully. Distances between service stations can exceed 100 km on some stretches. Carry a spare jerry can if driving.
- Connectivity: Mobile signal is limited or absent across large portions of the route. Download offline maps (Maps.me or similar) and relevant sections of iOverlander before departure.
- Travel insurance: Essential. Ensure your policy covers remote evacuation and adventure activities.
Getting There
By Air
The most practical international gateways are Buenos Aires (Aeropuerto Internacional Ministro Pistarini, Ezeiza) or, for the northern section of the route, Bariloche (Aeropuerto Internacional Teniente Luis Candelaria). Esquel also has a small airport with domestic connections. Verify current route availability and schedules with Aerolíneas Argentinas and other domestic carriers, as services change seasonally.
By Long-Distance Bus
Long-distance buses from Buenos Aires serve Bariloche and other northern Patagonian towns. Travel times are considerable — Buenos Aires to Bariloche is roughly 20–22 hours by bus. From Bariloche, regional services connect to El Bolsón, Esquel, and points south, though frequency drops sharply in more remote sections.
Cross-Border from Chile
Many travelers begin or end their journey on the Chilean side of the Carretera Austral and cross into Argentina via border passes such as Futaleufú, Lago Verde, or others. Border crossing procedures and specific pass requirements should be confirmed with Argentine and Chilean border authorities before travel, as seasonal closures apply.
Getting Around
Self-Drive
Renting a 4WD or high-clearance vehicle is the most flexible way to travel this corridor. Rental agencies in Bariloche offer vehicles suitable for ripio roads. Read the rental contract carefully — many agencies restrict travel on unpaved roads or into Chile; negotiate this explicitly if you plan a cross-border itinerary.
Motorcycle
The route is popular with motorcyclists, and a strong community of overlanders uses platforms like iOverlander to share current road and fuel conditions. Pack for unpredictable weather; wind in Patagonia can be severe.
Cycling
Long-distance cycling is feasible and practiced, but requires serious preparation. Prevailing Patagonian winds typically blow west to east and south to north — consider this when planning direction of travel. Carry substantial spare parts, as bike shops are rare south of Esquel.
Bus
Public bus coverage exists between larger towns (Bariloche–El Bolsón–Esquel) but becomes very limited or nonexistent on remote stretches. Hitchhiking is a locally accepted practice on this route and is widely used by budget travelers, though it carries the standard risks and unpredictability of any hitchhiking situation.
Ferry
Some lake crossings within the Argentine lake district — notably the classic 'Cruce de Lagos' route linking Bariloche to Puerto Montt in Chile — incorporate ferry segments. Verify current operators, schedules, and prices directly with the operators, as these change seasonally.
Things to See & Do
Los Alerces National Park
One of Argentina's most undervisited UNESCO World Heritage Sites, Los Alerces protects ancient alerce (Fitzroya cupressoides) trees, some estimated to be over 2,500 years old. Boat tours on Lago Menéndez are a highlight; these access stands of monumental alerces unreachable on foot. Verify tour availability and booking with the park administration or locally in Esquel and Trevelin.
Trekking and Hiking
Trails range from short nature walks to multi-day backcountry routes. Volcán Lanín (accessible from Junín de los Andes, slightly north of the core corridor) and the Reserva Nacional Lago Puelo near El Bolsón are popular shorter options. Backcountry trekkers should register with park rangers and carry topographic maps.
Fly-Fishing
Patagonian rivers and lakes — the Río Futaleufú, Río Palena, and their Argentine counterparts — are regarded among the best fly-fishing destinations in the world for introduced trout species. Guided operations exist in several towns; verify licensing requirements with local outfitters.
White-Water Rafting
The Río Manso near Bariloche and cross-border rivers offer rafting experiences across varying grades of difficulty. Several outfitters operate from Bariloche.
Wildlife Observation
- Andean condors are frequently seen soaring over mountain passes
- Huemul (Andean deer), a critically endangered species, inhabit forest edges — sightings are uncommon but possible
- Austral parakeets, Magellanic woodpeckers, and other Patagonian bird species reward patient observers
- Pumas are present but rarely seen
Food & Drink
Regional Cuisine
Food along this corridor is honest and meat-forward. Cordero patagónico (Patagonian lamb), often slow-roasted on a cross-spit (asado al palo), is the signature dish of the region and widely available in towns along the route. Venison and wild boar also appear on menus, particularly in estancias that offer meals.
Welsh Heritage in the Chubut Valley
The towns of Trevelin and Gaiman (the latter lies east of the Andean corridor) preserve a Welsh Patagonian cultural tradition dating to the 19th century. Teahouses (casas de té) serving traditional Welsh cream teas, homemade cakes, and preserves are a genuinely distinctive and historically rooted experience — not a tourist confection.
Craft Beer and Wine
El Bolsón has a well-established craft brewing scene; several small breweries operate in and around town. Patagonian wine regions (notably from the Río Negro valley) produce Malbec and Pinot Noir of increasing quality; look for these on restaurant lists rather than major supermarket imports.
Practical Notes
- In remote stretches, options narrow to basic almacenes (general stores) and occasionally a single restaurant per village. Carry emergency food supplies.
- Tap water is generally safe in established towns; verify locally in smaller settlements.
Practical Information
Emergency Contacts
Argentina's general emergency number is 911. Police: 101. Fire: 100. Medical emergency: 107. Verify whether these numbers are operational in the specific remote areas you plan to visit, as coverage and local response capacity vary significantly.
Currency and Payments
Argentina's currency and exchange situation has been subject to significant fluctuation. Travelers should verify current exchange rate policies, accepted payment methods, and cash availability before departure. In remote areas, cash is essential — do not rely on card payments.
Communications
- Purchase a local SIM card in Bariloche or another major town for data access where signal exists
- Satellite communicators (Garmin inReach or similar) are a worthwhile investment for remote travel in this region
Maps and Navigation
- Instituto Geográfico Nacional (IGN) Argentina produces the most reliable topographic maps for the region
- Garmin and OSM-based offline maps provide useful road-level navigation
Seasons and Road Conditions
- November–March: Best weather; most roads accessible; highest traveler volume
- April–May: Autumn colors, fewer travelers, cooler temperatures
- June–September: Many high passes close; some roads impassable without specific equipment; not recommended for most travelers
- Always check current road conditions with Vialidad Nacional or Vialidad Provincial before setting out
Safety
The primary safety concerns along this route are environmental rather than related to crime. Road accidents on ripio (gravel) roads are a genuine risk; loose gravel causes loss of vehicle control, and river crossings can be hazardous after rainfall. Drive at reduced speeds on gravel, keep headlights on, and never attempt an unfamiliar river crossing without first assessing depth and flow on foot.
Weather changes rapidly and severely in Patagonia. Conditions can move from clear to white-out or severe wind within hours. This applies equally to hikers, cyclists, and drivers. Always carry layers, waterproofs, and emergency supplies even on short day trips.
Wilderness distances mean that help can be hours or days away in an emergency. Inform someone of your planned route and expected check-in times. A satellite communicator significantly improves safety margins in remote sections.
Petty theft is uncommon in small Patagonian towns but apply standard precautions in larger hubs like Bariloche: do not leave valuables visible in vehicles, use hotel safes where available, and be aware of your surroundings in busy public spaces.
