Dear customer, here you can book the skip-the-line ticket for Underground Naples which will allow you to go directly to the entrance at the selected time, avoiding long waits in line.
This service naturally has an additional cost on the regular ticket.
If you do not find skip-the-line tickets available or you are not interested in them you can always go directly to Piazza San Gaetano 68 without any reservation. In fact, even if you find a queue, entry is always guaranteed to anyone who decides to queue.
Waiting times in the queue depend on several factors but vary from 10 minutes to a maximum of 90 minutes in periods of high turnout.
