Swimming:
Swimming is the absolutely the best at East Beach and area salt water beaches. The body surfing is great as well as the walks up and down the beach. Private parking means come and go as you please. If it's a burger you want you can go over to the 'Blue Shutters' for all kinds of beach snacks. There are also many fresh water facilities very close by.
The fall provides a special time to go hiking, biking, birding, sailing, golfing, antiquing, and (outdoor) reading.
Activities:
Wow! Misquamicut and Watch Hill a few miles away, Narragansett Beach (20 minutes) Block Island Ferry (20 minutes), Newport (30 minutes), Casinos (30-35 minutes), golf courses (everywhere). Providence with it's famous zoo is a short drive (30-35 minutes) as well as the Mall shopping in Warwick.
You can easily spend a day antiquing if that is your thing with the nearby flea market on Sundays. An overcast day you can drive to a number of nearby wineries and taste some of the best wines.
Bring a camera because there are many local roads that are declared 'scenic' and offer many opportunities for great photographs.
Restaurants:
South County has the best restaurants that will please everyone! I love casual dining, nearby restaurants have Rhode Island Clam Chowder and Clam Fritter's. Family dining at Aunt Carries rules! For those that like to tip a glass and smell that wonderful salt air, go to the Coast Guard House and hang out on the roof and watch the waves roll in. For a more sophisticated dinner the Shelter Harbor is lovely.
Other Activities:
Anything associated with the water.
