It looks like a lot of campgrounds, Audubon nature reserves, state parks, and the only major city is Providence which is museums and food.
Only thing I know about Rhode Island is that they made chickens there
Hope this helps!
Theres a killer arcade called Freeplay in Providence. One fee <$10 to get in and all the games are set to free play. Great pinball selection if you’re into that. Cheap beer and okish food while you’re there. 21+ most days.
To clarify: only Saturday.
If you only have one day, and it’s open, I would recommend visiting Rhode Island School of Design’s museum and campus. The RISD museum was surprisingly nice. Small but uncrowded - it was the type of place I could bring a sketch pad and draw for hours. There are probably other museums and attractions nearby, along with nice places to eat and drink. I don’t know much about outside of Providence though.
Rhode Island School of Design is one of the top art schools in the US. They have an art museum on campus that houses pieces like you’d find at actual city museums plus works by their students. https://www.risd.edu/
Go to North Kingstown beach and set up camp in front of this guy’s place
