Is it possible to walk from the cruise ship docks to the Cliff Walk?
It's a little over a mile to the start at Memorial Blvd. I guess it just depends on how comfortable you are with walking and how the weather is that day....
The trolley is easily accessed at the visitor center quite near Perrotti park where you will be taken from the ship. The ships can't be landside in Newport as it just isn't that big and the water isn't deep enough.
I would are the trolley. It's only a mile but it is literally uphill both ways. Only in new england
