Invierno in Lago Posadas
Descubre las mejores actividades, eventos y experiencias en Lago Posadas en invierno — desde aventuras al aire libre hasta cultura.
5 min de lecturaLago Posadas, together with neighboring Lago Pueyrredón, forms one of Patagonia's most remote and visually striking lake systems. Located in Argentina's Santa Cruz Province, accessible only by a long camino de ripio from Ruta 40, this area is a destination for those who actively seek the end of the road. In winter, de junio a agosto, it pushes even further toward the extreme.
The tiny settlement of Hipólito Yrigoyen (also known as Lago Posadas) serves as the only base, with a population of just a few hundred. In winter, the community hunkers down against the cold and wind, maintaining the basics of ranching life while the surrounding landscape freezes solid. The twin lakes maintain their remarkable turquoise color — a product of glacial meltwater — creating surreal beauty against the espolvoreado de nieve, wind-sculpted steppe.
The area is rich in geological wonders. Nearby petrified forests contain fossilized Araucaria trees millions of years old, and the surrounding badlands display colorful sedimentary layers exposed by erosion. In winter, these formations take on a spare, almost lunar quality under low sun angles. Getting here requires a committed effort — aproximadamente 90km on gravel from Ruta 40 — but the reward is experiencing one of Earth's most isolated landscapes in absolute soledad.

Importante para viajeros con auto de alquiler
The aproximadamente 90km camino de ripio from Ruta 40 to Lago Posadas is the only access. In winter, it can be icy, cubierto de nieve, and deeply rutted. Un 4x4 es absolutamente esencial. Cadenas para nieve must be carried. There is no cell phone coverage, no roadside assistance, and no other traffic for potential help. Carry full suministros de emergencia including combustible extra, food, water, warm clothing, and communication equipment (satellite phone or PLB recommended). This is genuinely remote and self-rescue capability is necessary.

Preguntas Frecuentes
Is Lago Posadas accessible in winter?
Technically yes, but it requires a capable 4x4, complete self-sufficiency, and acceptance of significant risk. The gravel access road can be impassable after heavy snow. This is not a casual winter destination.
Do the lakes freeze in winter?
The main lakes generally don't freeze due to their depth and constant wind agitation. Shallow edges may ice over, but the turquoise water remains visible — one of the area's great winter attractions.
Can I combine Lago Posadas with a Ruta 40 trip?
Sí, it's a detour from Ruta 40. Sin embargo, the 90km gravel access road each way adds significant time and difficulty in winter. Factor in at least a full extra day for the side trip.
Is satellite communication necessary?
Strongly recommended. There is no cell phone coverage in the area, and the remoteness means help is hours away even in good conditions. A comunicador satelital or PLB provides essential safety.
