Rome: Underground of Trevi Fountain & Spanish Steps Private Tour

This tour combines two sides of Rome rarely seen together — a hidden underground world most visitors never know exists, paired with one of the city's most iconic, photographed landmarks above ground. Instead of simply admiring the Trevi Fountain from the crowd like everyone else, travelers descend beneath it into Vicus Caprarius, an archaeological site discovered purely by accident, to see the actual 2,000-year-old aqueduct still feeding the fountain today — an experience accessible by guided visit only. As a fully private tour, the pace, depth of storytelling, and route are shaped entirely around your group, with no fixed schedule or crowds to compete with. It's the perfect blend of hidden, lesser-known Rome and classic, postcard-worthy Rome in a single, personalized experience.
