1. Atlantic City Boardwalk | Atlantic City, NJ
Atlantic City Boardwalk, the first boardwalk in the U.S., was built in the 19th century to keep sand out of the hotels and train cars on New Jersey’s Absecon Island. The four-mile boardwalk passes by the Absecon Lighthouse, Atlantic City Historical Museum, Boardwalk Beach, and casinos galore. There’s also the iconic Steel Pier, a 300-year-old pier filled with nostalgic amusement rides. No trip is complete without sampling saltwater taffy.
