The Normal Route is the simplest route, sometimes incorrectly called North, since in fact it is the Northwest Route. In general no short-shafted ice axe or ropes are needed. For practical purposes, climbers use ski poles and crampons. Going up by this route there are several itineraries; therefore, it is common to set up two or three altitude camps (“Plaza Canadá”, “Nido de Cóndores” and “Berlín” or “Cólera”). This route is the most chosen by climbers as it does not present any technical difficulty; this means that the climbers don´t require a previous climbing experience on rocks or ice. It may be hiked, just by walking. You may have to use crampons and fixed ropes for your security, depending on the conditions of the route.
