Paso Roballos is an international mountain pass through the Andes, joining Chile and Argentina, at an elevation of 715m (2,345ft) above the sea level. The pass links Cochrane and Bajo Caracoles.
The road to reach the pass, by the Chilean side is Ruta X-78 and by the Argentinian side is ruta provincial Nº 41. The connecting Chile-Argentina road through Paso Roballos is narrow and with less traffic than Chile Chico pass. It is very good at the beginning but deteriorates (corrugations and lose gravel) as it smoothly climbs to the pass were migration offices are. Going down to Bajo Caracoles-Argentina you can ride at higher speed but corrugations are present here and there. The pass is open throughout the year, although occasionally closed by snow.
This is a maintained road where a high clearance 2WD vehicle is able to travel safely at low speeds on long dry straight-of-ways, without losing control due to wash boarding, ruts, or dips.
The unpaved sections of the road can be impassable when wet. It is very important to check rainfall in this area before setting off and make sure you are well prepared for the trip.
