Easily the most rewarding route from Córdoba to San Luís, capital of the neighbouring province of the same name, is by the RP-34 and then the RN-20 beyond Villa Carlos Paz. The winding Nueva Ruta de las Altas Cumbres climbs past the Parque Nacional Quebrada del Condorito, a deep ravine where condors nest in cliffside niches, climbing over a high mountain-pass before winding back down a series of hairpin bends. The serene, sunny valleys to the west of the high Sierra Grande and Sierra de Achala, crisscrossed by streams and dotted with oases of bushy palm trees, are known collectively as the Traslasierra, literally “across the mountains”.
The self-appointed capital of the sub-region, Mina Clavero, is a popular little riverside resort. Near Nono, a tiny village at the foot of the northern Comechingones to the south of Mina Clavero, is the oddball Museo Rocsen. In a long valley parallel to the Sierra de Comechingones lies the picturesque village of San Javier, from where you can climb the highest summit in the Central Sierras, Cerro Champaquí.
