Camden Yards is the jewel not only of Baltimore, but of Major League Baseball. When the former train yard was converted into a historic stadium in 1992, it inspired a wave of similar sites across the country. Even when there isn’t a game, take a stroll down Eutaw Street, marked with every home run to hit it over the years. Still not close enough to the action? Tours are available regularly and will even score you a trip to the O's dugout.
