Fort Frederick State Park Professional Review and Guide
"One couldn’t ask for a better location for a campground. Fort Frederick sits up the hill, easily accessible via a paved path (Fort Frederick Road). Down from the fort, you cross the C&O Canal Towpath running alongside Big Pool. The campground sits between the towpath and the Potomac River. Fort Frederick is perhaps the best place to view the span of Maryland’s military history.
The fort’s location makes it a prime attraction. Parkland contains sections of the Potomac River, C& O Canal, Big Pool, and the Western Maryland Rail Trail (WMRT), a 23-mile paved path that follows the former Western Maryland Railway line. The Potomac allows for great swimming (be careful: the currents can be deceptively swift midriver), boating, and fishing. The species of fish, both native and introduced, number in the dozens—bass, carp, catfish, crappie, eel, herring, perch, pickerel, shad, sunfish, and trout among them."
