Underground tours in Naples are very popular with multiple sites and entry points, this one being the main location. Entrance is via an alley along Via dei Tribunali, one of the main stretches in the historic center, and on a Sunday noon it was packed with visitors waiting for their tour times.
Like probably 70-80 people waiting in a 12 x 20 foot area...a fair number of staff on hand wrangling the lines, telling people/groups with pre-bookings to line up in front of those without. Each person basically has to talk to a staff member to figure out exactly who they should be standing behind. Then there are staff members calling out times for each tour at the front, Italian then English alternately. I'm not sure why they don't implement an easier, more straightforward system, for each language--one line for prebooked and one line without.
Tickets can be booked in advance online by tour language and they ask you to be there 15 minutes prior to your time slot. This is most certainly not only recommended, but required if you want to avoid inadvertently missing your timeslot due to the confusing line as mentioned above. Also their website refers to the online tickets as "skip-the-line" though to be clear you are essentially just booking a spot in advance, you still need to wait in line at the entrance.
And hands down book in advance. They "guarantee" entry at the door (as I heard a few different staff members mention to certain people in line), however what they don't initially mention is this is only after all pre-booked visitors enter, so this could mean an indefinite wait of 30 minutes, an hour, 1.5 hours...who knows. For safety reasons entry is only possible via guided tour, and there are limits to the size of each group. They definitely push it though, considering my group of about 35ish was one of several groups to go down in staggered times of about 15-20 minutes apart.
Once the guide directs the group to enter the pathway leading underground, they make you line up along the stairs while another group exits, then your group can enter. It's several flights down (then back up) so I saw some elderly with walking handicaps and families with strollers struggling. Honestly I wouldn't recommend coming here if you fall into either group. I imagine it could be dangerous for the former (think slippery stone in some areas) and there was a toddler crying during two-thirds of my tour that made for a very distracting experience if you consider the cavernous reverberations.
After waiting in line for about 15-20 minutes outside, then another 10-15 minutes on the stairs inside, the tour itself lasted about an hour and fifteen minutes after we finally got downstairs. It was very informative and our guide tried her best to crack jokes and maintain a light-hearted atmosphere while at the same time projecting her voice as loud as possible and telling other nearby groups to keep their voices down (yes, bc there were a few different groups in close proximity sometimes so she had to practically yell to be heard). She shared about the history, functions (aquifer, munitions storage, landfill, war bunker, etc) and unique conditions (cool temps and high humidity) that makes this subterranean complex such an integral part of Naples' story.
The last 20 minutes was dedicated to visiting the ruins of an ancient Roman amphitheater only a few minutes walking from the Sotterranea entrance/exit. It's in a separate building altogether on a residential street and it was intriguing to see the intersection of antiquity and modern life.
