Ruta 40 Gas Stations: Southern Patagonia Fuel Map
Complete guide to gas stations along Argentina's legendary Ruta 40 in southern Patagonia. Station locations, distances, fuel types, and survival tips for the most remote highway.
Argentina's Ruta Nacional 40 is one of the world's great road trips - and one of its most challenging for fuel planning. Stretching over 5,000 km from the Bolivian border to Río Gallegos, the southern Patagonia section features vast distances between tiny towns and gas stations that may or may not be open.
This guide covers: El Calafate to Río Gallegos (the most-traveled southern section)
Key facts:
- Total distance: ~650 km (El Calafate → Río Gallegos)
- Gas stations: 6-8 along the route
- Longest gap without fuel: ~210 km
- Road surface: Mix of paved and gravel (ripio)
El Calafate (Starting Point)
El Calafate is the gateway to Los Glaciares National Park and has the best fuel infrastructure in southern Patagonia.
