If you’re in the mood for a little more adventure, keep on cruising to Naples, 35 miles from San Gregorio Matese. There are plenty more fabulous things to see and do here, including Castel dell’Ovo and Naples National Archaeological Museum. Amalfi, 55 miles away, is another destination that’s worth the trek. Visit Amalfi Cathedral and Villa Rufolo, two top-notch sights in the area.
