Lago Posadas

Twin lakes, one turquoise, one sapphire, divided by a land bridge laced with fossils.

#Water#Solo#Couple#Relaxed#Wandering#Eco

Lago Posadas and Lago Pueyrredón lie either side of a narrow land bridge, and they are different colours — Posadas turquoise with glacial flour, Pueyrredón midnight blue with depth — two tones across one plateau, with Monte San Lorenzo's 3,706 metres standing behind in perpetual cloud. The landscape has appeared in Argentine photography for half a century without ever becoming commercially known.

The lakes are glacier-fed and joined at an isthmus of glaciofluvial deposits whose sediments carry marine fossils from the ocean that stood over this ground in deep time. San Lorenzo, one of the Patagonian Andes' highest summits, feeds both systems from its ice fields and offers a serious mountaineering approach from this side to the properly equipped. The small village beside the lakes supports far more than a transit stop — signed walks, viewpoints, simple village tables, a provisions shop and bakery for the road — but the region's terms hold: long gravel approaches, fuel and road conditions confirmed before committing, water activities chosen according to wind rather than assumed calm, and guanacos outnumbering people the whole way in.

Best For

Solo

For whoever has finished the Chaltén–Calafate circuit and wants the unmediated version — a two-tone glacial landscape, a road that requires care, and a village base that lets each day follow one shore instead of pushing through.

Couple

The two colours visible simultaneously from the isthmus viewpoint, ice fields above, produce a specific private quality in people who find this place without guidance.

Why This Place
  • The paired lakes hold visibly different colours, read together from the road above.
  • Marine fossils in the isthmus sediments recall the ocean that once stood here.
  • The gravel approach runs long and empty — guanacos outnumber people the whole way.
  • Condors ride the morning thermals level with the western shore's viewpoints.
What to Eat

Cordero and lake trout — Patagonia's plain rewards, done well.

Mate and tortas fritas on the shore, watching the two blues meet at the isthmus.
