Spend your third day in Spoleto enjoying the beautiful outdoors. Start with a hike to the Ponte delle Torri, a magnificent medieval aqueduct that offers stunning views of the surrounding countryside. Afterward, head to the Parco del Sole, a lovely park where you can relax, have a picnic, or go for a bike ride. If you're feeling adventurous, try your hand at rafting or kayaking on the nearby Nera River. End the day with a leisurely walk along the picturesque Spoleto Valley.
