The walk from Trevi to the castle at Poreta is suited to everyone, but you need to approach it with a slow and constant pace as there are numerous ups and downs over the hills, and stop now and again for a well-deserved break. It’s all downhill from Trevi to the Monastery of the Madonna delle Lacrime, well worth a visit if it’s open, and then over a paved road that leads to a panoramic trail. You’ll pass through the little town of Alvanischio, then ascend over olive groves set on terraced plots delineated by drywalls, rounded structures that hold up the soil and look almost like vases. In order to grow olive trees on the steepest of slopes, man very wisely crafted one of the most difficult, grandiose and wondrous irrigation systems in the history of agriculture in the Mediterranean. From the water fountain at Camponi, take the paved road first, then get on the dirt road to reach an old monastery. From there go downhill towards the castle of Campello, whose white walls stand out in the landscape. Replenish your water supply at Lenano and then get back on the road lined with heartfelt votive shrines devoted to the Madonna. The road is paved and continues downhill all the way to Poreta, your destination. Use whatever energy you might have left to climb to the top of the castle of Poreta, a part of the next leg of the journey.
