Catoctin National Recreation Trail

Catoctin National Recreation Trail (CNRT) is a 26.6-mile point-to-point hiking route along the eastern-most ridge of the Blue Ridge Mountains in Frederick County, Maryland, linking Gambrill State Park, Frederick Municipal Forest, Cunningham Falls State Park, and Catoctin Mountain Park. The trail surface is soil and rock, with an average grade around 6 degrees.

Expect a physically demanding hike overall: the route is characterized as strenuous to demanding, with notable elevation change, rocky outcrops, and stream crossings, especially as you move through the forested ridge and into/out of the state-park units. Footing is a key part of the day here.

The south trailhead is at Gambrill State Park, and the route runs north to its north trailhead in Catoctin Mountain Park. The trail passes through multiple managed units and also parallels the Catoctin Mountain National Scenic Byway along portions of the corridor.

Catoctin Mountain Park is where the hike gets especially interesting historically and culturally: the route includes historic districts such as Camp Greentop and Camp Misty Mount, plus historic and prehistoric archaeological resources along the way (including Indian flint napping sites and Colonial-era charcoal hearths).

Trail structure includes access to several scenic vistas and overlooks, including views of the Monocacy River Valley from points along the line. The north–south through route also skirts lakes and crosses State Scenic Byway corridors as it moves between jurisdictions.

Planning-wise, water matters year-round, and dogs must be on leashes at all times in the Catoctin Mountain Park segment. Wear sturdy hiking shoes, and note that rock formations named in park guidance (Chimney Rock, Wolf Rock, and Hog Rock) restrict dogs from those specific areas.

Historically, portions of the CNRT were built in the 1930s by the Works Progress Administration and the Civilian Conservation Corps, and the trail was later upgraded and completed by the Potomac Appalachian Trail Club between 1979 and 1982; if you’re hiking it in full, this is one of the reasons the route feels like a long, consistent corridor rather than a patchwork.
