Trip Essentials for Puerto Montt
Gas & Juice: Critical Pit Stops
Don't get stranded. These are your essential fuel and supply points.
Chaiten Service Station
Fuel & Supplies
The first major town after Pumalin, crucial for checking tire pressures and stocking up supermarket supplies.
Coyhaique Plaza
Fuel & EV Charging
The only large city on the highway, equipped with high-speed EV chargers, large supermarkets, and mechanical garages.
Cochrane Station
Fuel & Supplies
The last reliable major fuel station before entering the remote southern end of the highway leading to Villa O'Higgins.
Insider Driving Tips
Over 60% of the Carretera Austral is unsealed (rough gravel); drive slowly (40-60 km/h) to prevent gravel slips and windscreen chips, and carry at least two spare tires.
The highway requires crossing several key car-ferries (such as Hornopiren to Caleta Gonzalo); book these ferry crossings weeks in advance during summer months.
Gas stations can be over 200km apart; always top off your fuel tank at every single station you encounter, regardless of how much fuel remains.
Bring plenty of physical Chilean pesos; rural towns, ferries, and national parks rarely accept credit cards.

Pumalin National Park
Caleta Gonzalo Café
