C & O Canal: Drive-In Campground Sites Professional Review and Guide
"All campsites along the canal have two things in common: the Potomac in front and the towpath behind. This means an endless supply of boating, fishing, swimming, and hiking opportunities. Every site is some what different in character, however, in that the surrounding topography changes and nearby historical sites and towns (or lack thereof) change the experience of camping in each site.
As a general rule, expect a large, cleared area with individual campsites scattered around the available space. While the sites are usually big, they’re never terribly far from one another. Antietam Creek has as its main draw point its proximity to Antietam National Battlefield, which is a short drive (or canoe ride) away."
