Sorrento claims one of the Amalfi Coast's most picturesque harbors. Take in the whispering groves of lemon trees along the Amalfi Drive, or board a hydrofoil to the serene and sunny island of Capri. You can also tour nearby Pompeii, the fascinating ruins of a city covered in lava and ash from the A.D. 79 eruption of Mount Vesuvius.
