The Newport Cliff Walk is, along with the Newport mansions, among the most popular Newport RI attractions. Once you begin walking the path you'll understand why.
The Breakers mansion is the crown jewel of Newport Rhode Island mansions. It was the first mansion I saw growing up, and is the most popular attraction in the entire state of Rhode Island (300,000 visitors annually).
Lots of shopping and restaurants, right on the harbor.
Newport's famous 10 mile drive.
