Naples Underground Skip-the-Line Ticket and Guided Tour from Piazza San Gaetano

This is the ticket to book for the underground passages of Naples when the queue is the worry: it combines a skip-the-line entry with a guided tour. The visit starts at Piazza San Gaetano 68.

Below the street, the route follows hidden passageways and old cisterns, with remnants of the Greek and Roman city still in place. The guide ties these to the longer history of Naples.

The booking cannot be cancelled or refunded, which is worth checking before choosing a date.
