Looking for Rhode Island place to see and things to do

What state parks have hookups?

We always hit up local breweries and Gray Sail is in Westerley. If you like ipa's Captains Daughter is pretty good. I just happen to have some in the fridge.

Depends of couse on what you like to do.
We toured RI last year and we spent a few days at Burlingame state park followed by a few days at Charlestown breachway. The beach being a short walk from our site at the breachway was nice. The stone / rocks surprised us at the surf edge but once past that no problem.
If you stay at the breachway (dry camping) you may use the facilites at Burlingame.

If you paddle (we canoe) Ninigret pond is nice. We saw oyster farming for the first time up close. Horseshoe crabs moving under us. We put in at Ninigret park.
The park is a hidden jem, check it out on Friday night, the free observatory was worth a stop.
They also have a neat little swimming hole with lifeguards.

Slater mill http://www.slatermill.org/ is a neat few hours.

The hot air balloon festival was neat http://www.southcountyballoonfest.com/

As other mentioned the cliff walk is a nice peek at what you can't afford. Or maybe you can but are smart enough to have a camper instead.

X3 on the Newport Mansions. Also, check out Water fire in Providence. Try a little seafood hut like Flo's clam shack or Iggy's Doughboy and chowder house. There are several companies offering dinner cruises on Narragansett Bay. A trip to Block Island would also be a great day. If you like wine, try a tour of Newport or Sakonnet vineyards. Downtown Westerly shops on the ocean are nice, as well as Mystic CT. Mohegan Sun abd Foxwoods casino are just over in CT, too.

I forgot to add that we also did one of those ghost tours or something of that nature. Very informative and learn a little.

We stayed at Melville Ponds CG which is a municipal park and got a membership to the Newport Mansions for the year. It was one of our favorite trips.

X2 on the mansions. Cliff Walk and Ocean Drive. Newport walk around town then lunch/dinner and drinks. We have stayed Here a couple of time when our kids were younger. They loved the slide.

Newport..the mansions....about a 45 minute drive from Normandy Farms
