From the Refugio Nuevos Horizontes, approach the saddle between Ilinazas, and cross it, until you find other paths that can take you to the ridge on the right, which you will reach soon.
Start climbing the scree and sand slope, and aim to gain the ridge early to avoid this very unpleasent climbing. Climb to the top of the ridge and head towards a big tower. Go around it on the right side and drop down, traverse this section called "El Paso de la Muerte" (potential snow/ice) and walk toward several gullies. Climb up one of them with few 5.3 moves, carefully looking for the easy way up, and get to the top.
Way down: use the same route.
One rope if you need to feel comftable on the rock section. Crampons and ice axe plus some snow ice pro if route has snow or ice (mainly December to February)
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
