See: Newport Cliff Walk
"My favorite way to see Newport is a trek on Cliff Walk. The 3.5 mile seaside trail offers beautiful vistas of said cliffs on one side and a peek across the backyards of some of the enclave's stateliest homes on the other. While much of the path is paved, it becomes more of a cliff climb towards the southern tip of the island, and ends on a sandy spit the locals lovingly refer to as 'Reject's Beach' for its placement next to a stretch of tony bathing clubs." - Mackenzie
