This is a walkway that follows the canyon at the bottom of the hills of La Peña. It was built by the Town Hall so that locals and visitors could enjoy the natural beauty of the place. This route starts in the north side of La Peña and goes along the canyon in two sections. The first one is 5 metres high and goes along the river level. The second section crosses the river through a hanging bridge until reaches a tunnel parallel to the river. This leads to another path that will take visitors to the town of Castril. The access to this route is from the church and from Parque de la Arboleda Perdida or the park of the lost grove.
