Carretera Austral Southern Section
Patagonia's remote gravel highway
The final 240-mile stretch of Chile’s Carretera Austral from Villa O’Higgins to Puerto Yungay crosses some of Earth’s most pristine wilderness. This gravel lifeline winds past the Northern Patagonian Ice Field, where glacial valleys carved by ancient ice reveal turquoise lakes and granite spires. The road dead-ends at Puerto Yungay, requiring a ferry across the Pascua River to continue into Argentina’s vastness.
Moderate to difficult depending on weather — Patagonian storms turn washboard gravel into mud pits without warning. High-clearance vehicle minimum with spare parts and emergency supplies; fuel available only in Villa O’Higgins and Puerto Yungay. Best November-March when daylight stretches 16 hours, but prepare for sudden weather changes. No permits required but inform Carabineros of travel plans. You’ll witness untouched Patagonian wilderness that fewer people see than summit Everest.

Frequently asked questions
Can a stock 2WD truck handle the Carretera Austral Southern Section, or do I need 4WD?
A high-clearance 2WD can manage the route in dry summer conditions, but 4WD is strongly advisable. Patagonian weather can turn sections into deep mud overnight, and you're 240 miles from reliable help if you get stuck.
What months is this section actually drivable without serious risk of being snowed or rained out?
November through March is the reliable window. Outside those months, snow closes passes and rain turns the gravel into a muddy mess that can strand vehicles for days. April gets unpredictable fast.
Do I need any permits or entry fees to drive the Carretera Austral Southern Section?
No permit is required to drive the route itself, but some side roads into national park areas require an entrance fee paid at park gates. Bring Chilean pesos in cash — card readers don't exist out here.
What's the hardest part of this route and what should I actually expect?
The worst sections are corrugated washboard gravel that'll shake your rig apart if you push speed, combined with blind corners on narrow ledge roads above river valleys. It's not technically extreme, but sustained remoteness and no bailout options are what get people — mechanical problems here are serious.
How far do I need to fuel up before leaving, and is there any gas along the 240 miles?
Fill every time you see a pump — fuel stops are scarce and unreliable on this stretch. Carry a minimum 20-liter jerry can as backup. Villa O'Higgins at the southern end has fuel but supply can be inconsistent; don't count on it being there when you arrive.
