From Matteotti town square in Assisi, take the road leading to Gualdo Tadino and, after 500m, turn right to Costa di Trex: from here, take the mule track on the right. The trail, once used to reach the mountain summit with the mules, is mainly an uphill trail: only at the summit it crosses the meadows and meets trail no. 55 passing by the doline of Mortaro delle Trosce.
