The Cambridge to Paris Rail-Trail is one of the easiest ways to turn Cambridge into an active day out. The route follows an old rail corridor along the Grand River, with a mix of woodland, river views, farm edges and small-town Ontario scenery rather than a hard urban cycling path.
It works for cyclists, runners and walkers who want a longer outing without complicated navigation. The full ride to Paris is a proper excursion, but shorter out-and-back sections from Cambridge still give you the river landscape that makes the trail worthwhile.
