Sylvan Falls is a 1,437-acre Adirondack Park property in Hopkinton, St. Lawrence County, defined by sole ownership of a spectacular 25-foot waterfall and over 2.25 miles of frontage along the West Branch of the St. Regis River, a designated APA recreational river running nearly 75 miles from the Saranac Lake region to the St. Lawrence River. Above the falls the river runs slow and deep, ideal for paddling and fishing; below, it drops through fast, boulder-strewn water over exposed bedrock, splitting around a small island reached by footbridges from the western bank. The southern 0.75 miles of frontage runs along both banks, the remainder tracing the eastern boundary. Sylvan Falls Road sits close enough to the falls for a home to be within sight and sound of the water, an exceptional homesite under the APA's Rural Use classification (approx. 8.5-acre average lots). Terrain is gently rolling for the Adirondack foothills, ranging from about 985 to 1,310 feet, with well-drained soils and a well-stocked young hardwood forest with strong appreciation potential. Two independent town-road access points -- White Hill Road to the west and Sylvan Falls Road to the east -- serve an extensive internal road and trail network suited to hiking, skiing, and ATV use. The property is enrolled in New York's 480A Forest Tax Program (Certificate No. 40-133), transferable to new ownership and a meaningful reducer of annual carrying costs. A 15-year management plan covers 1,124 eligible acres, with commercial harvests planned for 2024-2034 offering near-term timber revenue. Existing recreational lease camps along Sylvan Falls Road generate approximately $9,959 annually and may be assumed or terminated. Potsdam is 14 miles northwest; Montreal 2 hours northeast; Albany roughly 3 hours southeast. Few northern Adirondack properties combine this scale, river frontage, and sole waterfall ownership on one parcel -- a generational recreational or conservation holding. Offered at $1,450,000.
