The Appalachian Trail travels from Maine to Georgia. The 40 miles of the recreational trail in Maryland crawl along the backbone of South Mountain, and are perfect for 3-4 day hiking and camping trips. Popular day hikes along the Appalachian Trail include Annapolis rock, Washington Monument, and Weverton Cliffs.
Home to the Baltimore Orioles, Oriole Park at Camden Yards is a Major League Baseball ballpark built in 1992. Designed as a "retro" major league ballpark, Oriole Park closely resembles the old jewel box parks. Get a good view of the downtown skyline as you watch the game, and be sure to stop by the statue of Babe Ruth just outside the stadium.
