About Flat Rock Falls

Flat Rock Falls is a tucked-away cascade set within New York’s Grass River Wild Forest, offering a peaceful stop for hikers who appreciate layered ledges and the soft roar of falling water. The site is on land owned and managed by SDC and carries the area’s SCA designation, which helps protect the natural character of the falls and surrounding forest. The falls’ broad, flat rock formations create several low cascades and shallow pools that invite photography and quiet observation rather than swimming or heavy use. Access to Flat Rock Falls feels suitably wild without being remote: the approach threads through mixed woods and opens onto a scenic rock apron above the water. Seasonal color and spring run-off are especially striking; because the site is managed by SDC within the Grass River Wild Forest, visitors should follow leave-no-trace practices and any posted rules that protect fragile habitats and the stream corridor.

The Setting

Flat Rock Falls sits at 1,040 feet within Grass River Wild Forest, fed by the Oswegatchie River, in the foothills of New York.

Trail & Hike Details

Trail Description
