Descend 40 metres beneath the streets of Naples into a labyrinth of Greek aqueduct tunnels, Roman cisterns, and WWII air-raid shelters with a private expert guide. Naples' secret underworld is as dramatic as anything above ground.
What to expect
Your expert guide leads you through a narrow 16th-century palazzo entrance and down steep stairs into the Greek-cut tufa tunnels that honeycomb the entire city. The 45-minute route passes ancient cisterns, Roman theatre fragments (visible through glass floors), and a wartime shelter still bearing graffiti from 1943. The temperature drops to a cool 14°C — a relief in summer — and the acoustic silence is extraordinary. Emerging back into the sunlit chaos of the Spaccanapoli quarter feels like time travel in reverse.
Good to know
Located in central Naples, 15–20 mins by private transfer from Molo Beverello cruise terminal. Not suitable for severe claustrophobia; passages narrow to 70 cm in places. Pre-book private slots via the official site. Pair with lunch at a historic Neapolitan pizzeria on Spaccanapoli for a complete half-day Naples experience.
