If you’re up for a little more adventure, keep on driving to Naples, 25 miles from Castel Campagnano. There are plenty more fabulous things to see and do here, including Castel dell’Ovo and Naples National Archaeological Museum. Amalfi, 40 miles away, is another destination that’s worth the journey. Stop by Amalfi Cathedral and Villa Rufolo, two must-see attractions in the area.
