Walking along the Via Ferrata "La Muela" in Villahermosa del Río is a real challenge to vertigo, because the 100 metres of difference in level over its 140 metres make this Via Ferrata one of the most vertical and aerial routes in Castellón. A route that offers us spectacular views of the rugged surroundings of this beautiful village in the interior of Castellón that is part of the Penyagolosa Natural Park.
