From San Clemente, go through the town of Torre de’ Passeri and begin to climb toward Santa Maria del Monte di Bolognano (entrance to Maiella National Park); from here, reach the quaint village of Muséllaro, descend into the wild valley of the Orta River and climb up to the beautiful medieval church of St. Thomas Becket. From the church, go through the hamlet of St. Thomas and continue to the village of Salle.
