The waterfall is entirely man-made, resulting from the construction of the Erie Canal overflow spillway.
The drop is approximately 35 feet, created as water spills from the canal level into the creek basin below.
The bedrock underneath the waterfall consists of Clinton formation shale.
Holley Canal Falls is one of the few places where you can observe the direct interaction between the historic Erie Canal and local geography.
The park grounds contain the remnants of a former stone mill foundation from the mid-19th century.
Holley Canal Falls is a unique man-made waterfall located on the Erie Canal in Orleans County, New York. The falls were created in 1825 when builders of the Erie Canal designed a spillway to drain excess water from the canal into the East Branch of Sandy Creek. The waterfall features a series of cascading tiers dropping approximately 35 feet over shale bedrock. The park surrounding the falls contains remnants of 19th-century canal infrastructure, including stone walls and historical markers. Visitors can access the area via a paved path that leads directly to the base of the cascade. The site is a rare example of industrial engineering functioning as a natural-looking landscape feature. It is integrated into the larger Erie Canalway National Heritage Corridor.
From the bottom of the wooden observation staircase looking upward to capture the full tiered effect of the falls.
Wear sturdy, water-resistant footwear as the area near the base of the falls can be muddy and slippery.
The park is compact, so plan to combine this visit with a bike ride or walk along the nearby Erie Canalway Trail.
Bring mosquito repellent during the summer months as the shaded, damp environment attracts insects.
Do not attempt to climb the shale ledges, as the rock is fragile and loose, posing a significant slip and fall hazard.
Stay on marked trails to prevent soil erosion and protect the delicate shale rock formations near the falls.
