Trip of 297 km paved from General Acha until the crossing on the river Colorado and the entrance to the county of Black River . There are fuel, food and lodging in General Acha and 25 de Mayo. In Chacharramendi, good services. The road is right and of great monotony, for what seeks advice to make a high of 15 minutes every two hours to avoid accidents.
