Begin your day by taking a train from Rome to Naples. Once you arrive at the Naples station, head to the Piazza Garibaldi and grab an authentic Neapolitan pizza from Sorbillo. The pizza here is some of the freshest and tastiest in Naples.
Take a train to Pompeii and spend a few hours exploring the ancient ruins. Pompeii is an archaeological wonder and provides a unique glimpse into the life of ancient Romans. Be sure to wear comfortable shoes, and if you're visiting in the summer, be prepared for the heat.
Take a train to Sorrento and head to Ristorante Bagni Delfino for lunch. Try the spaghetti con vongole, a delicious pasta dish with clams. After lunch, take a stroll through the historic center of Sorrento and take in the stunning views of the Bay of Naples.
Take a train to Positano and spend the rest of your day exploring this charming cliffside town. Walk through the town's narrow streets and take in the beautiful views of the Mediterranean Sea. Be sure to stop by Fornillo Beach, a secluded and picturesque beach that is perfect for a dip in the ocean.
If you have extra time, consider taking a boat tour of the Amalfi Coast or visiting Capri island. If you have less time, skip Pompeii and spend more time in Sorrento or Positano.
