We have a free afternoon, so it is time to walk a little bit. We travel towards Castellar de N’Hug, one of the official Charming Villages and the point of arrival of the Cement Train. The town is known for its spectacular natural setting, its Romanesque architecture, and its enormous croissants. It is also famous because it is home to the source of the river that forms the backbone of the entire province of Barcelona, from the Pyrenees to the Mediterranean: the Llobregat. The path to its source is short and well-established, with wooden ladders and handrails. As we get to the end, we see the spectacular waterfall bursting straight from several cracks in the rock wall. Before it gets dark, with a couple of croissants weighing a kilo each in hand, we reach Ripoll where we spend the night.
