Other Facts About “Little Rhody”

• Rhode Island is small enough that only one area code is required. The 401 area code services the entire state.
• There is a 77-mile hiking trail across the state. The North-South Trail runs from the Massachusetts border in Burrillville in the north to Charlestown on the Atlantic Ocean in the south.
