Fishing is ok. You would be better off going to the Black Pont break wall at north end of East Matunuck state beach. Yes you will need a fishing license. You can get one online.
I don't know if you can fish there, but you get the license in the walmart or online fishing area and a good place to fish is in the pulgatory in newport.
I don't fish. I go there to enjoy the views.
