Catoctin is a mountain ridge just north of Frederick, MD. This ridge is framed by 2 very famous civil war battlefields - Antietam to the south and Gettysburg to the north and is the site of a local Sept gran fondo that visits all these landmarks. This ridge also is home to the presidential retreat of Camp David. The ridge is characterized by climbs of about 1000 feet in 2 to 3 miles. Some of the backroads have some pretty steep pitches as you will experience!
