Also try Sand Hill Cove for family beach (fairly calm, not big waves); also Narragansett Town Beach is very nice too. Matunuck and East Matunuck is very nice, more surf if that's what you like. Misquamicut Beach has more surf but can have an undertow at times.
I really miss the beaches ! waaaaahhhhh.
And the seafood, and the pizza. waaaaaahhhh.
