Seclantás, Los Cardones National Park, Tin Tin’s straight road, Cachi, Molinos and the gorge of Las Conchas River, are the milestones of the Calchaquíes Valleys’ circuit. The most exciting challenge for bikers is the Cuesta del Obispo, an impressive snail-form slope with a 1.200 m. drop. Other options are the Salinas Grandes (Big Salt-pans) and the Quebrada de Humahuaca (Humahuaca Gorge) joined by the Lipán Slope.
Mendoza’s arid mountains permit crossing the Andes Mountain Range by the Vergara Path, between the cities of Malargüe and Curicó (Chile), with ascending slopes of 500 m. and descending slopes of 1.000 m., by the occidental side.
Those preferring breathtaking descends can take the roads of the Altas Cumbres (High Peaks) or the Puentes Colgantes (Hanging Bridges) path, in the province of Córdoba.
In Tandil, at La Movediza mount (Moving stone), biking circuits take the old rails used for stone transportation, a hard route that requires maximum concentration. At the Sierra de la Ventana hills, the Cura Malal circuit is the best choice for mountain bikes.
Lanín, Nahuel Huapi or Los Alerces National Parks also guarantee proper environments for this kind of circuits.
In the last years, the Transpatagonian crossing, from the Pacific to the Atlantic has become very popular. One of the circuits ends at the city of Puerto Madryn, after crossing the inhospitable Somuncurá plateau. There are also circuits entirely along the Atlantic coast, by the cliffs roads, leaving from the city of San Antonio Oeste, passing by the marine fauna reservations.
"Confines of the 40s” is an expedition for lonely bikers and lovers of danger. Its existence is so mythic that, in spite of having areas without water or posts, bikers from the whole world challenge to do it.
