This is the classic and best-documented way to climb Pico de Posets. It is generally a non-technical alpine ascent, but it is still a serious high-mountain outing because of the elevation gain and the length of the day. The route follows established mountain paths and then steeper upper slopes and ridge terrain near the summit. In normal summer conditions it is mostly a hiking-style mountaineering route, but snow, ice, or poor visibility can make navigation and footing more demanding. It is the standard route described in guidebooks for the peak and the one most commonly used for summit attempts.
