Explore ancient Vicus Caprarius beneath the Trevi Fountain, then enjoy Rome’s iconic sights on a private guided tour.

About this tour

See Rome from two remarkable angles on a private tour that pairs the Trevi Fountain’s lively piazza with the archaeological world beneath it. Descend into Vicus Caprarius, an underground site discovered by chance, and explore the remains of the ancient city alongside the 2,000-year-old aqueduct that still supplies water to the fountain.

With an official licensed guide, uncover the stories behind this hidden corner of Rome before returning above ground to admire the Trevi Fountain. The private format keeps the experience focused on your group, bringing together lesser-known history and one of the city’s most celebrated sights. The tour also includes the Spanish Steps, adding another classic landmark to your Rome visit.

Choose this Rome Underground Trevi Fountain and Spanish Steps Private Tour for a close-up look at the city’s layers, from ancient engineering to iconic streets. Book your guided visit and discover what lies beneath the fountain.

How this score is calculated

This tour has no TourTruth score yet: Viator doesn't show a usable rating for it. It gets a score as soon as a provider lists one.

How the score works
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10. Tours without a usable provider rating are not scored.
