Rating it only a 3 because it was a LOT harder than the easy ratings I saw here. My iPhone app said we did over 59 “floors”. It is only 2.3 miles or so, but the up and down, and the footing made it pretty tough on this 64 year old! Took us 2.5 hours going from Monterosso to Vernazza. Views were spectacular to be sure. But it was not easy.
