My wife and I have walked the 7th St. to Freedom Park portion of this Greenway many times (alone or with our dogs) and we love it. The scenery is great. Lots of walkers, bikers and runners on nice days. The Metropolitan is right on the route and has stores and restaurants. Alternates between sunny and shady, plenty of places to rest on benches or on the grass. Public restroom is available between The Metropolitan and Morehead St., and are clean and well maintained.
We have also walked the 12th St. to Cordelia Park section of this Greenway and it is a hidden gem. Not nearly as busy as the section I reviewed above, and as such I wouldn't recommend for a woman walking or running solo. Nonetheless, we've never felt at all unsafe and it is a very pretty walk.
