Ruta Provincial 23 – Cueva de las Manos

The dirt and gravel stretch of RP23 cuts through the heart of Patagonian nowhere, leading to one of South America’s most significant archaeological sites. Ancient handprints cover the canyon walls at Cueva de las Manos, left by hunter-gatherers who roamed these windswept plains millennia before Europeans arrived. The route follows the Pinturas River canyon through desolate beauty that hasn’t changed much since those early artists worked.

This is moderate overlanding – high clearance essential, 4WD recommended for wet conditions. The 46-kilometer stretch from the main highway can get rough, especially after rains when the clay sections turn slippery. Spring through fall offers the best conditions, though Patagonian weather remains unpredictable. Fuel up in Perito Moreno before heading out. Wild camping is possible along the route, but the wind never stops. You’re here for the profound connection to human history and the stark beauty of untamed Patagonia.
