DESCRIPTION: Excellent section. It starts in Navàs, we soon arrive at l'Ametlla de Merola where we will begin our journey along the "Ruta de les Colònies Tèxtils". Along some paths parallel to the Llobregat river we will enjoy the silence of the forest, the murmur of the river, the songs of the birds, in short a delight for all the senses. We will pass through the middle of old textile colonies from the late 18th and early 19th centuries, engines of the industrial revolution in Catalonia, a great corner of history that will immerse us in our own skin. Cal Riera, Cal Vidal, Cal Marçal, Cal Pons with its Gothic church known as the Bergadà Cathedral, art and history along a simple but more wooded section with riverside vegetation to end at the entrance to the Pre-Pyrenees.
