If you are a lover of mesmerizing ocean views and historic mansions, the Cliff Walk in Newport, RI, will provide you with the best of both worlds. While some might consider the Cliff Walk to be more of an unconventional hike, it has been an official national recreation trail since the '70s and is by far one of the most popular attractions in Newport. Be sure not to abandon the path when cozy cafes and buzzing boutiques start popping up. If you do, you'll unfortunately miss out on the close-up views of Rhode Island's rocky coastline.
