Review & FAQ:

This guided tour of the Naples Underground Geothermal Zone aqueduct system of Naples descends to a depth of over 130 feet. Participants will explore the cavities, tanks, and labyrinth of Naples’s tunnels while guides share their history, legends, stories, mysteries, and myths. Tours are family-friendly. Some of the tour is by candlelight, and a few tunnels are extremely narrow, which may be uncomfortable for some people. Keep in mind that the tunnels are a near constant 62°F with 90% humidity. Travelers should meet at Piazza Trieste e Trento. Tours in English are on Saturdays and Sundays, and there is an Italian-only tour on Thursdays.
