Rhode Island has some of the best beaches in the USA. The smallest state has 40 miles of coastline — which is why we call it the Ocean State.
The best beaches are in South Country, about 45 minutes from Providence — see list at: https://www.southcountyri.com/beaches-and-towns/beaches/
RI State beaches are free to the public, however you’ll have to pay for parking — see list here: https://www.visitrhodeisland.com/things-to-do/beaches-water-sports/beaches/state-beaches/
Our favorite best is Misquamicut Beach in Westerly
Misquamicut State Beach is perfect for families. A beautiful wide sandy beach stretching for seven miles. You’ll find here bathrooms, changing areas, food stands, a big beach pavilion and many shaded areas.

Best beach for adventurers: Mohegan Bluffs, Block Island
“Any ocean lovers with a wild side, those who may appreciate a bit more of a rugged vibe, this one’s for you. Mohegan Bluffs is a patch of sea cliffs that sits on the southern tip of Block Island, which is only accessible by ferry (visitors depart from either Point Judith, RI or New London, CT). At about 150 feet tall, the tall clay cliffs are just past the Southeast Lighthouse and are reminiscent of the Cliffs of Moher in Ireland. The view from the top is stunning — you can even see Long Island (specifically, Montauk in the Hamptons) across the Atlantic.” (source: Lonely Planet)
