If you visiting Newport, you need to stop at Newport Vineyards. It's on rt 138, just a couple of miles north of the the Newport bridge. For $5 you can sample a variety of their wines, and keep the glass when you're through. Case club members (which we are) can taste their wines for free. They also have public tours twice daily.
Fall River is about 25 minutes east of Providence. If you come to the area and have an interest in war history, you've got to stop at Battleship Cove. We've been there over a half-dozen times. The Battleship Massachusetts is the primary attraction here, but they also have the Destroyer Joseph P. Kennedy, Jr, a Balao-class submarine, USS Lionfish, a Soviet-built missile corvette, Hiddensee, and two rare PT boats on display. On the lower decks of the Massachusetts you will find an extensive PT Boat Museum, with thousands of war memorabilia which will keep you browsing for hours. On the other side of the parking lot there is also a 1920's carousel housed in a separate building. It is still running daily. What a great day trip this is!
This event takes place in downtown Providence on most Saturday nights from May to October. The WaterFire is a free event which centers on bonfires that blaze just above the surface of the three rivers that pass through the middle of the city. It's a great place to just hang out, have a drink, listen to music, and see the illumination of the rivers. Parking in Providence is a bit of a pain, but there is ample pay parking at the Providence Place Mall. Arrive early, and browse the many shops there, then it's a short walk to the Waterfire.
