Rhode Island is the smallest state in the country, but don’t let that fool you into thinking it has little to offer. One of the original U.S. colonies, Rhode Island was the last to officially become a state. Newport has over 400 miles of coastline, and the state also has many historical monuments and locations, as well as varied plant life. Forests cover three out of every five acres of the state, so that’s a lot of plant life.
