As we progress, the road enters the Els Ports Natural Park. The route narrows and the gradient increases until the tarmac gives way to a dirt track. This is where the climb up Montsagre begins, a demanding and technical ascent that combines steep ramps with rocky and uneven terrain, typical of the limestone geology of the massif. Among the pine trees, the views gradually open up, revealing the course of the Ebre river and, in the distance, the Cardó-el Boix mountain ranges. It is a purely natural, silent and rugged environment.
