This is the best-known documented mountaineering line on Pedraforca-El Calderer. It follows the Canal del Verdet on the north side and uses fixed equipment in places, so it is more of an alpine via ferrata / easy climbing route than a pure hike. The route is exposed in sections and can be serious if wet, icy, or crowded. It is commonly used as an ascent line to the summit area of El Calderer. Route-finding is straightforward in good conditions, but loose rock and exposure require care. It is one of the classic ways to climb the mountain from the north side.
