Paso Vergara to Puerto Ramírez — Carretera Austral Backcountry via Río Palena
Patagonia before the tourists find it.
This is where the Carretera Austral reveals its unfinished, genuinely wild side. The route begins at Paso Vergara on the Argentina-Chile border southwest of Río Pico, drops into the Palena River valley, and grinds northwest to Puerto Ramírez where the road reconnects with the paved spine of Ruta 7 near Lago General Palena. The Río Palena crossings — some bridged, some not — define the experience. When the river is running hard after rain, the unbridged sections demand a read of current, a solid snorkel height check, and nerves. The track surface alternates between loose volcanic gravel, clay that turns to axle-deep mud in wet conditions, and exposed bedrock shelves through temperate rainforest corridors that feel genuinely prehistoric.
This is a Difficult-rated route that will punish unprepared rigs. A lifted 4WD with all-terrain tyres, recovery gear, and a high-lift jack is the minimum. Snorkel is strongly advised. Carry fuel for at least 400 km of range — there is nothing between the border and Puerto Ramírez. Best season is November through March; outside of that window, the clay tracks become impassable and the rivers run unpredictably high. Chilean border crossing formalities apply at Paso Vergara — get your paperwork sorted in Coyhaique or Comodoro Rivadavia. What you earn is some of the most dramatic and least-travelled Patagonian scenery on the continent, period.

Frequently asked questions
Can a stock Tacoma or 4Runner run this trail?
No. A stock rig will get you into serious trouble here. You need a lifted 4WD with a snorkel — the Río Palena crossings can run thigh-deep or higher depending on snowmelt, and the muddy sections will swallow low-clearance bumpers. Recovery gear and a second vehicle are not optional.
When is this route actually passable?
November through March is your window. Outside of that, snow closes the passes on the Argentine side and the river crossings become dangerous from winter runoff. Even in summer, a rain event can spike river levels fast — Patagonia doesn't care about your timeline.
Do you need permits to cross the border here, and are there fees?
Yes — this is an international border crossing between Argentina (Chubut Province) and Chile (Aysén Region), so you need valid passports and must clear customs and immigration at the official border post. Vehicle import permits (for taking your rig into the other country) are required at the crossing. No trail-specific fee exists, but verify current border crossing status with Chile Dirección de Vialidad before you go, as this crossing can be seasonally restricted.
What's the hardest section and what should I expect?
The Río Palena crossings are where rigs get stuck or drowned — multiple ford points with rocky, uneven beds and current that shifts with daily melt. Beyond the river, the track through the rainforest transition zone throws deep ruts, off-camber shelf road, and mud that gets worse after any precipitation. Budget extra time and scout every ford on foot before you drive it.
Is there any fuel or resupply between Paso Vergara and Puerto Ramírez?
No. There is nothing on this 140 km stretch — no fuel, no stores, no cell service at all. Top off in Palena (Chile side) or the nearest Argentine town before you start, carry extra fuel for the full route plus a buffer, and bring all food and water you'll need. The dispersed camping along the route is excellent, but you are fully self-sufficient from the moment you leave pavement.
