I know we've adapted the idea to some of our own cities-San Antonio, Sioux Falls, New York--but who knew the original river walk was along the Tiber?
My first night in Rome, I walked along it myself for a bit. My Campo de' Fiori studio, heaven on earth btw, is a long block from the Ponte Sisto, one of Rome's many beautiful bridges.
I instantly saw you can walk along below and that not many people do. (I also learned you want to walk along the south/west side of the river. On the other side are homeless encampments where people poo on the ancient brick sidewalk and did not seem terribly overjoyed at my presence).
Anyway, I was jet-lagged beyond belief but managed to stagger down at twilight and mingle as who would want to miss even a minute of the wonder?
