The hike begins in Valle del Arenas and continues right along the side valley Cortaderas. This valley is dominated by three big mountains: Punta Italia (left), Yamakahua (right) and Cortaderas in the background. To get to camp 1, a moraine field must be crossed, which is marked by a few stone walls that follow the lines of the moraines. Tents can be set up there. Camp 2 can be set up at the end of Valle Cortaderas, in the middle of the snow field, where a plateau 4,000 m above sea level is located.
The ascent begins here. Shortly after leaving the camp, you are faced with an area with crevasses, which you can best go around on the right side (northeast). Caution, on the southeast slope there is a large bergschrund of a rope length and a climbing inclination of 80°. Early in the season it can be crossed over the snow bridges. After mastering this obstacle, there is a traverse in east direction of about 30° inclination. It ends at a further bergschrund, which must be tackled with the utmost caution. Then the trail continues on the southern slope along a gully of approximately 45°, through snow and ice, and with some difficult steps. The inclination is 70° in some areas. The route from camp 2 to the end of the gully, which ends at some rock ledges, takes about 4 hours. Now turn towards northeast in order to climb to the ridge of the southern slope. The rock is poor quality at this place, difficulty III, and is connected to a gully of difficulty IV. Once this is mastered, turn to the north to a snow field with a 60° inclination and which leads to the summit after 50 meters. The descent is via the pass between Yamakahua and Cortaderas, which offers a beautiful rappel, when crossing a bergschrund.
