Local Insight:Rome wasn’t just built on seven hills, but on layers of history. The Basilica of San Clemente, visited on some tours, is a literal timeline: a 12th-century church sits atop a 4th-century basilica, which sits atop a 2nd-century Mithraic temple, built over a 1st-century Roman apartment.

Trastevere, the setting for many top food tours, means “across the Tiber.” For centuries, it was a working-class neighborhood separate from central Rome, which preserved its authentic, village-like charm and incredible culinary traditions you can taste today.

The “Bocca della Verità” (Mouth of Truth) is famous, but few know the ancient Roman drain cover was likely used in pagan rituals. Local legend says it bites the hands of liars, a myth popularized by the film “Roman Holiday” with Audrey Hepburn.

Walking is the only way to truly discover Rome’s hidden layers. You’ll stumble upon a 2,000-year-old cobblestone, smell fresh pizza from a century-old bakery, and turn a corner to find a Bernini fountain—all in a single stroll. It’s the ultimate Roman adventure.
