The route follows the red and white GR-1 markings to the plain of La Llana Pass. At several points, other trails appear, but they are shortcuts, variants, or detours to different parts of the mountain range. The path is easy to follow despite the steep slope and the loose stone scree. The trail passes near the impressive limestone tower of Peña de los Cencerros and continues toward the mouth of the two prominent peaks of the mountain range at the entrance to the La Llana plateau. At the GR-1 marker, a path leads off to each side, and the Historic Trail continues straight ahead to Santa Cruz de Campezo. The climb to the summit of Joar begins along the path on the left, first through bushes and then through a welcoming beech forest nestled in the limestone slope of the mountain's north face. These unique forests are isolated near the peaks and are the southernmost beech forests in Navarre.
