There is one boulder in this area off of Buckeye Brook Rd. The boulder is pretty fun to play on though not extremely challenging. There are some really satisfying jugs that you can grip on a few of the routes. All in all, I wouldn't necessarily make a special trip for the boulder, but if you're in the area it's worth checking out.
Directions:
From Newport:
Take 138 W across bridge (toll)
Take US-1S
Turn slight right onto Kings Factory Rd
Straight onto Shumankanuc Hill RD
Turn left onto Buckeye Brook RD
Park in the larger parking lot on the north end of the road and walk 100 ft down the trail on the southern side of the road until you find the boulder.
