"This tour will take the better part of your day (it's six hours start to finish). But going by bike to these outer city sites—the old Appian Way via the ancient aqueduct—is the easiest and most entertaining way to see them. Plus you won't want to cut out early: it ends with wine and some nibbles in Caffarella Park, which is so expansive it feels like you're in the countryside even though it's smack in the middle of the greater city. Bikes feel brand new and the confidence of the tour guides will put any nervous riders at ease." - Erica Firpo, Maresa Manara
