History buffs will love Gettysburg. Travelers can tour the roughly 6,000-acre Gettysburg National Military Park (the site of the Civil War’s bloodiest battle) and check out other historical attractions, such as the Jennie Wade House (where the only civilian casualty from the Battle of Gettysburg died) and the Eisenhower National Historic Site (a farm that once belonged to former President Dwight D. Eisenhower). Those who prefer a spookier glimpse of Gettysburg’s past can sign up for a ghost tour. After sightseeing, visit an antiques store to find a piece of war memorabilia to take home as a souvenir.
