If you have time for a mansion tour, make it The Breakers. Built by the Vanderbilt family as a summer “cottage,” it has 70 rooms, gold-leaf ceilings, and marble bathrooms bigger than most apartments. Tours run daily and it’s absolutely worth it! Fun fact, it's also where they shot many scenes in The Gilded Age!
If you haven't already caught on, Newport has some pretty iconic ocean views and the Lawn Terrace at Castle Hill Inn is no exception! If you can manage to get in (this place is quite popular), claim an Adirondack chair out on the Lawn Terrace and grab a quick drink. Note, this view is best enjoyed during a sunset.
