Cunningham Falls State Park

Cunningham Falls S.P. sits in Maryland. Swimmers come for a natural day on the water without resort amenities. The park is anchored by Maryland's largest cascading waterfall. A gorgeous, multi-tiered rush of water tumbling over ancient rocks. And a 43-acre man-made lake that together create a scenic swimming spot. The air here smells of damp forest floor and mountain laurel, and the tree canopy closes in tight enough that you forget how close you are to civilization. The park sits within the Catoctin Mountain range, where hardwood forests drape the hillsides in dense green from spring through early fall, and erupt into fiery color come October. The falls themselves cascade roughly 78 feet in a series of steps over smooth schist rock, pooling into cool, clear water at their base. Sunlight filters through the canopy and catches the spray, making the waterfall a particularly magical place in the morning hours. The surrounding terrain is lush with native plants and home to abundant wildlife. You may catch a glimpse of white-tailed deer, wild turkey, or any number of forest birds as you make your way through the park's trail network. Visitors wade and splash at their own discretion, drawn naturally to the cool water pooling near the falls. The rocky bottom and cascading nature of the falls mean footing requires care, and conditions can change with rainfall, so it pays to be cautious and aware of your surroundings. Treat Cunningham Falls S.P. as a wild swim: no lifeguard, variable depth, and rules that can change by season.

Cunningham Falls S.P. works well as a day trip from Frederick or Thurmont. Stock up in town, then head to the water with food, water, and sun protection. Pair the swim with a stop at Martins Mill Bridge (about 17 mi away) or browse more Maryland waterfall spots in our directory. For the full list in Maryland, see our state directory.

Access to the swimming area is via Cunningham Falls State Park. An entrance fee is typically required. Parking, especially at the William Houck Area, fills quickly on summer weekends. The swimming spot is unofficial, meaning it is not a staffed or specially maintained beach; visitors assume personal responsibility.

The park's historic iron furnace reflects Maryland's industrial heritage, while the surrounding area, including Frederick, offers a glimpse into the region's colonial and Civil War-era history.

Visitors are encouraged to follow Leave No Trace principles to protect the park's environment. Efforts are ongoing to preserve native wildlife and plant species within Catoctin Mountain's ecosystem.
