Lago 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 gravel road from Ruta 40, this area is a destination for those who actively seek the end of the road. In winter, de juin à août, 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 snow-dusted, 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 — environ 90km on gravel from Ruta 40 — but the reward is experiencing one of Earth's most isolated landscapes in absolute solitude.

Min Moyenne

-5°C

Precipitations

Very low, averaging 10-20mm par mois. The semi-arid steppe receives minimal moisture. Light snow and frost are more common than rain.

Vent

Severe. Open steppe location means constant, powerful wind. Gusts can exceed 100km/h during storms.

Ensoleillement

Environ 8 heures de lumière du jour. Clear skies are frequent, maximizing available light.

Winter at Lago Posadas is defined by extreme cold, persistent wind, and vast emptiness. The dry continental climate produces clear skies but bitter temperatures. Frost is constant, and wind chill is the defining feature of outdoor conditions. The lakes rarely freeze due to their depth and wind action, maintaining their turquoise color toute l'année.

Lake Viewpoints

The turquoise waters of Lago Posadas and Lago Pueyrredón against the frozen steppe and snow-covered mountains create extraordinary visual contrasts. The narrow land bridge separating the lakes is particularly photogenic.

Petrified Forest Visit

The Bosque Petrificado near Lago Posadas contains fossilized trees millions of years old. Accessible in winter on dry days, the petrified trunks amid the frozen landscape create a surreal, timeless scene.

Geological Formations

Colorful badlands, eroded canyons, and sedimentary rock formations surround the lakes. Winter light, especially low-angle morning and afternoon sun, dramatically illuminates these geological features.

Wildlife Observation

Guanacos, foxes, and condors inhabit the area toute l'année. The sparse winter landscape makes wildlife more visible. Condors soaring above the frozen steppe are a particularly powerful sight.

Non Disponible Cette Saison

All organized tour servicesFishing at the lakes (season closed)Camping facilitiesAny structured recreational activities

Hebergement

Extremely limited. Hipólito Yrigoyen has one or two very basic hospedajes. Availability must be confirmed in advance. Expect simple rooms with wood heat. Bring your own food supplies as restaurant options may be nonexistent in winter.

Affluence et Tourisme

You will almost certainly be the only tourist in the entire area. This is one of the most remote and least-visited places in Patagonia, even in summer. In winter, isolation is total.

Tarifs

Prices are minimal where services exist. The main expense is fuel and location de voiture for the long drive to get here. Arrange a vehicle from a major city. Carry extra fuel as there are no guaranteed fuel stations between Ruta 40 and the lakes.

Conditions de Conduite

Important pour les voyageurs en voiture de location

The environ 90km gravel road from Ruta 40 to Lago Posadas is the only access. In winter, it can be icy, snow-covered, and deeply rutted. A 4x4 is absolutely essential. Chaînes à neige must be carried. There is no cell phone coverage, no roadside assistance, and no other traffic for potential help. Carry full emergency supplies including extra fuel, food, water, warm clothing, and communication equipment (satellite phone or PLB recommended). This is genuinely remote and self-rescue capability is necessary.

Questions Frequentes

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?

Yes, it's a detour from Ruta 40. However, 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 satellite communicator or PLB provides essential safety.
