TheOneToGo
Rome after dark rewards the traveler who moves through it, not just stands before it, so the best night tour puts you in the streets with the monuments lit up and the crowds gone.
Our pick
Riding through Rome in a vintage Vespa sidecar as the Colosseum, Trevi Fountain, and the Pantheon glow against the night sky is a genuinely different thing from walking past them in daylight. You cover ground quickly enough to feel the city open up, slowly enough to absorb every piazza, and the sidecar format means you and your companions share the whole view together rather than trailing a guide single-file through crowds.
If our pick doesn't fit
A guided on-foot loop of the same landmarks at a fraction of the price, good if you prefer walking to riding.
Combines cycling with wine stops and bites, so it doubles as dinner, though it runs longer than the sidecar tour.
