The landscape between Perito Moreno and Bajo Caracoles best embodies most people’s concept of Patagonia – sparsely populated and at times empty lands stretching to the horizon. Why most people venture to these parts at all is to see the magnificent Cueva de las Manos Pintadas (Cave of the Painted Hands), one of South America’s finest examples of rock paintings and listed as a UNESCO World Heritage Site. It can be approached either by road along a sidetrack just north of Bajo Caracoles, or, better, by walking or riding up the canyon it overlooks, the impressive Cañón de Río Pinturas.
From the canyon rim, it’s a spectacular two-hour walk to the cave paintings. The path drops sharply to the flat valley bed, and continues to the right of the snaking river, nestling up against rock walls and pinnacles that display the region’s geological history in bands of black basalt, slabs of rust-coloured sandstone and a layer of sedimentary rocks that range in hue from chalky white to mottled ochre. Bring binoculars for viewing the finches and birds of prey that inhabit the canyon, plus food, water, a hat and sunscreen.
At the point where the course of the Río Pinturas is diverted by a vast rampart of red sandstone, you start to climb the valley side again to reach the road from Bajo Caracoles and the entrance building to the protected area around the paintings, where there’s a modest display. Unfortunately, some parts of the site have been tarnished by tourists etching modern graffiti on the rock – hence the fence that now keeps visitors at a distance – and you can only access the cave accompanied by a guardaparque on a one-hour guided walk.
The cueva itself is less a cave than a series of overhangs: natural cutaways at the foot of a towering 90m cliff face overlooking the canyon below, a vantage point from which groups of Paleolithic hunter-gatherers would survey the valley floor for game. Despite the rather heavy-handed fence that now frames them, the collage of black, white, red and ochre handprints, mixed with gracefully flowing vignettes of guanaco hunts, still makes for an astonishing spectacle. Of the 829 handprints, most are male, and only 31 are right-handed. They are all “negatives”, being made by placing the hand on the rock face, and imprinting its outline by blowing pigments through a tube. Interspersed with these are human figures, as well as the outlines of puma paws and rhea prints, and creatures such as a scorpion.
